Every aircraft has 3 axis fly by wire, jf17 has analogfbw
LOL...i'm just wondering what is so called "analog fbw"on JF-17.some smartass with so called "Comprehension" might give some explaination in detail?

JF-17 Thunder – Lightning Strikes Twice

Three Pakistan Air Force (PAF) JF-17s are attending this year’s Paris Air Show. The type will be making a welcome visit after the Pak-Sino-developed Thunder visited the event in 2015, and a lot has happened to the program since then.

Right now the last three Block 2s are on the Aircraft Manufacturing Factory (AMF) final assembly line at Pakistan Aeronautical Complex (PAC) Kamra, which will eventually help to equip a seventh operational unit later this year. Meanwhile, the first JF-17 has undergone a major overhaul at PAC Kamra’s Aircraft Repair Factory, and there is a dual-seat JF-17B, 17-601, undergoing test and evaluation in Pakistan. A decision from the PAF leadership on a new AESA radar for the Block 3 JF-17s is pending and is expected by November, followed by its first operational sortie early next year. Then, in deals that were signed in late-2017, AMF will assemble 50 Block 3 JF-17s and 26 JF-17Bs. Next year Air Engineering Depot 102 at PAF Base Faisal will start overhauling the jet's Klimov RD93 powerplant.

There is a lot going on to occupy the minds of the PAF leadership, and operationally the JF-17 is playing a major part in the defense of Pakistan’s skies, with six operational squadrons. During the PAF’s recent confrontation with the Indian Air Force, known in Pakistan as Operation Swift Retort, PAF Chief of the Air Staff Air Chief Marshal Mujahid Anwar Khan told AIN in mid-April, “The aircraft performed very well against the IAF Mirage 2000s and their Mica missiles, as well as the MiG-21 Bison and its R-73 Archer AAMs.”

On the export front, Aviation Industry Corporation of China (AVIC) has delivered six JF-17s (four single-seaters and two dual seaters) to the Myanmar Air Force, while PAC has sold three examples to Nigeria, and these should be delivered after the pilots are trained in Pakistan. Sales and marketing of the jet were split between PAC and China National Aero-Technology Import & Export Corporation (CATIC) in 2015. CATIC is engaged in discussions with Egypt surrounding the Block 3s, while PAC continues to talk to Malaysia.


Having flown around 100 hours of test and evaluation sorties, the first JF-17B to be delivered to Pakistan was having an air-to-air refuelling system fitted in mid-April.

PRODUCTION LINE
More than 100 JF-17s have now come off the AMF assembly line, where the wings, horizontal tail, vertical tail, and forward fuselage, representing 58 percent of the fighter, are built. They are matched with the remaining 42 percent built in Chengdu in China, including the mid- and rear- fuselages that are airfreighted to PAC Kamra. The three fuselage sections are mated at the JF-17 subassembly line and are pushed through on a large trolley to one of the four docks in the final assembly facility.

That’s when the avionics, wiring, undercarriage, harnesses, and Klimov RD93 powerplant are added, while the Martin-Baker Mk16 ejection seat comes later. The aircraft’s air-to-air refueling probes are not necessarily fitted on the assembly line, although all the necessary plumbing has been put in place since the production of Block 2 13-129.

After being towed down to the flight test shed, the newly built JF-17s are put through five functional check flights (FCFs) by one of the four qualified test pilots based at the co-located Test and Evaluation Squadron (TES). Three PAF pilots have qualified at the Boscombe Down-based Empire Test Pilot School for the JF-17, but now most of them go to Xian in China to get their qualifications. When the author met Squadron Leader Ali in April, he was about to test-fly the latest JF-17 to leave the assembly line. He went through a six months training program in China after flying with two operational JF-17 squadrons. Working alongside him in the flight test shed was Boscombe-qualified Group Captain Imran, who spent two years during the early days of the JF-17 test program at Chengdu flying the prototypes and was more recently the first JF-17 Combat Commanders School (CCS) commanding officer. He told AIN, “During the FCFs we push the aircraft to the limit, right through the complete envelope, to assess the handling qualities, checking the systems and aircraft performance.”

Once the FCFs are completed the PAF then puts the JF-17 through a further check flight and if there are no snags, the aircraft will be officially handed over.

PAC chairman Air Marshall Ahmer Shahzad told AIN, “Production of subassemblies has already started for the first two 50 Block 3 aircraft, to be assembled next year, and will be followed by another 12 in 2021, 2022, 2023, and 2024. We will assemble eight dual-seaters this year, followed by 14 in 2020, and the remaining four in 2021.”

Building the JF-17 since 2009 has catapulted PAC into the serious business of fighter production, a feat that not many countries can boast, particularly in Asia. The chairman said he is keen to build on this. The company has already built a high-speed aerial target and is close to the completion of an indigenous UAV.

BLOCK 3 JETS
The JF-17 Block 3 enhancements will involve new avionics, including a helmet-mounted display and a holographic wide-angle head-up display, better electronic warfare systems with integrated self-protection kit, as well as a missile approach and warning system, an increased payload, and more sophisticated weapons like a fifth-generation short-range air-to-air missile. It will be the ultimate JF-17, and with an AESA radar will have the capability to employ longer-range weapons and track multiple aircraft.

A decision on a new AESA radar for the Block 3s is expected to be made by the end of the year. There are now three Chinese contenders, which were all shown at last year’s Zhuhai Air Show, while Leonardo’s Grifo-E is still on the table.

Nanjing Research Institute of Electronics Technology's KLJ-7A is being marketed by China Electronics Technology Group Corporation in air- and liquid-cooling options. The second contender, which was displayed at the Zhuhai Air Show last November along with the two Nanjing examples, comes from Leihua Electronic Technology Research Institute (LETRI), another air-cooling AESA known as the LKF601E. AVIC has thrown its weight behind this option and claims it was the first air-cooling radar. Replacing the JF-17’s original KLJ-7 is simply a case of taking out the old system and inserting the new one. The PAF’s Flight Test Group is currently working the options.

WEAPONS OPTIONS
The PAF’s JF-17s are operational with the SD-10 beyond visual range air-to-air missile (AAM) with a data link and initial mid-course guidance, PL-5EII infrared short-range AAM, C-802 anti-shipping missile, and a stand-off capability courtesy of its Indigenous Range Extension Kit integrated with the Mk80 series of general-purpose bombs. The PAF chief of air staff recently told AIN that the JF-17 is better than many contemporary aircraft in three areas but would not provide any more details, although the air-to-sea mode is undoubtedly one of them.

At IDEF 19, held in Istanbul in early May, an Aselsan source confirmed that deliveries of the first of 50 Aselsan targeting pods for the JF-17s will commence "within a few months," which will provide the JF-17 with a laser-designator capability, working with JTACs on the ground in the air-to-land integration role.

Air Commodore Rashid Habib, JF-17 deputy chief project director, told the audience at the IDEAS 18 Air Power Conference in Karachi, that the JF-17 had flown 40,000 operational hours. He added that the JF-17B would be fitted with a missionized rear cockpit for combat training and operations, a three-axis fly-by-wire kit, and a fifth-generation advanced short-range air-to-air missile.

Analog fbw is that composite fbw system in that tin can which you people developed so that beggers can get what they are actually able to pay off,....strike twice :)):))
With a single proof of even an engagement ,only chinese friends can claim such idiocity,oh i forgot chinese ones ran away of being afraid against an armed militia despite lossing the fellow comarade .....what kind of drug do these pakis amd apparantly now chinese take ,they havent selected a radar yet people claim that they will fly first operational sortie next year. How ever this exposes the so called chinese dreams of developing an aesa ,the so called selection of radar is on from 1.5 years yet they dont know what will they get....keep claiming and screaming ,the result says that the so called junk fighter could even able to enagage 2 mirage2000snds despite being numerically superior and all it manages is to drop bombs with out accuracy and then ran away like they always do.....

LOL...yeah.....

Analog fbw = composite fbw ??? don't make up your own stupid theory...

'Analog' is relative to 'Digital'...Analog control signal or the digital control signal
Analog systems

All "fly-by-wire" flight control systems eliminate the complexity, the fragility, and the weight of the mechanical circuit of the hydromechanical or electromechanical flight control systems—each being replaced with electronic circuits. The control mechanisms in the cockpit now operate signal transducers, which in turn generate the appropriate electronic commands. These are next processed by an electronic controller—either an analog one, or (more modernly) a digital one. Aircraft and spacecraft autopilots are now part of the electronic controller.[citation needed]

The hydraulic circuits are similar except that mechanical servo valves are replaced with electrically controlled servo valves, operated by the electronic controller. This is the simplest and earliest configuration of an analog fly-by-wire flight control system. In this configuration, the flight control systems must simulate "feel". The electronic controller controls electrical feel devices that provide the appropriate "feel" forces on the manual controls. This was used in Concorde, the first production fly-by-wire airliner.[16]

In more sophisticated versions, analog computers replaced the electronic controller. The canceled 1950s Canadian supersonic interceptor, the Avro Canada CF-105 Arrow, employed this type of system. Analog computers also allowed some customization of flight control characteristics, including relaxed stability. This was exploited by the early versions of F-16, giving it impressive maneuverability.[citation needed]
typically, Su27 has the 'Analog fbw ' so has the early model F16. and F-15 has the hybrid electronic/mechanical system
-----------

FC-1/JF-17 is always called 'Hybrid Flight control'. the main architecture is based on the 'Digital Flight control computer'...but

in the pitch axis -digital full authority quadruplex FBW system
in the yaw and roll axis- hybrid electronic/mechanical system

on JF-17B/Block3, those two axis control was replaced by digital full authority quadruplex FBW system as well... here comes the three-axis digital fly-by-wire- the full digital FBW system

LOL...i'm just wondering what is so called "analog fbw"on JF-17.some smartass with so called "Comprehension" might give some explaination in detail?

Even though I know ignorance is hard to cure , let me try

Heard about relaxed static stability (RSS ) ?

Almost all recent 4 and 5 generation fighters have RSS base design except for JF17/FC1 lolzzzz .

F16 LCA GRIPEN RAFALE EUROFIGHTER F18 etc etc are all RSS based design except for JF17/JF17B/FC1.

JF17/FC1 only so called modern fighter which is not RSS design based , basically a 3 generation design feature ( by US nomenclature ) and one of the reasons why PLAAF never gave a fuck about it , except for fanboys and porkies.:pound:

In simple words a RSS design based aircraft is designed to be aerodynamically unstable.

RSS changes the dynamics of the aircraft while dramatically enhancing its maneuvering capabilities.

An aircraft with RSS design will have the center of gravity aft of the neutral point. As we shift the center of gravity aft of the neutral point , stability is lost and the aircraft will start deviating from its trimmed state.so shifting the center of gravity back gives us a more responsive and maneuverable aircraft but with the added risk of uncontrollable behavior which cannot be contained by manual input. however this behavior is useful if we want high angle changes and even high AOA quickly.

RSS configured aircrafts are near impossible to control by pilot input, so an artificial stability is imposed by using computers , servos and sensors as parts of a fully digital fly by wire (FBW) control system working in all the three axis that is pitch, yaw and roll.

Advantages of RSS design coupled with FULL FBW are

1.it provides good handling capability

2.it also provides invariant response with respect to variations in aerodynamics , fuel etc and facilitates robust performance.

3.it enables the pilot to fly the mission without worrying about exceeding of flight parameters beyond the safe limits.in flight safety is increased.

4.precise response control , reduced lag and overshoots results in vastly improved response and tracking accuracy of the pilot airframe system.

Also RSS design based aircrafts with tri/quad redundant digital FBW can implement additional highly redundant fail safe advanced safety modes like

1. auto low-speed recovery (ALSR) incase of impending stall during nap of the earth missions or low speed maneuvers etc. The aircraft automatically takes control and recovers the aircraft.

2. Disorientation recovery mode (DRM) to fight pilot disorientation in the high seas ( a common cause for crash at sea ) or in the clouds etc. When the Pilot gets disoriented in such situations, he can press a switch (panic button) provided in the cockpit then the aircraft takes over the controls and recovers itself to level flight optimally (with minimum loss of speed or altitude).
Etc

And the reason why FC1/JF17 came out with analogue flight controls and later a hybrid flight control system and then later the JF17B twin seater came with full digital FBW minus the RSS design which is the reason why FBW was invented by the Americans in the first place lolzzz :pound:

Compared to a RSS design based fighter the advantages of implementing FBW in a aerodynamically stable aircraft ( non RSS ) is minimal except for a slight reduction in size , weight and power (SWaP) parameters.

It will provide bare minimal improvements in aerodynamic performance , superior handling capabilities , stable invariant response etc if at all compared to a fighter aircraft with a FBW designed to go hand in hand with its inherent aerodynamically unstable RSS design from the design stage itself.

So incase you still don't understand , a rough analogy of non RSS design JF17/FC1 with back ported FBW is like a 50cc mopeds spring suspension replaced with air suspension system lol. One can expect a reasonable comfortable ride while dreaming of Harley Davidson like ride lol :pound:

Actually I have no complains to the Chinese regarding JF17 and FBW blah blah...... , I appreciate them on their cooperation with the madrassa educated porkies - beggers can't be choosers can they ? :biggrin2:

Stop crapping with all these digital and analogue bullshit

FBW was implemented to control RSS based design ( aerodynamically unstable ) fighter aircrafts.

Blunder is a aerodynamically stable aircraft design like a 3rd generation fighter like mirage III , MiG-21 etc and implementing FBW on a stable fighter aircraft is going to do jack shit except for SWaP gains. Primary functionalities of FBW is lost in blunder aircraft to a large extent.

Posting nonsense here with an iota of knowledge.

aerodynamically unstable ... relaxed static stability... blah,blah ,blah....

I'm just wondering ...so called 'aerodynamically unstable ' on which axis ?

Right now the last three Block 2s are on the Aircraft Manufacturing Factory (AMF) final assembly line at Pakistan Aeronautical Complex (PAC) Kamra, which will eventually help to equip a seventh operational unit later this year. Meanwhile, the first JF-17 has undergone a major overhaul at PAC Kamra’s Aircraft Repair Factory, and there is a dual-seat JF-17B, 17-601, undergoing test and evaluation in Pakistan. A decision from the PAF leadership on a new AESA radar for the Block 3 JF-17s is pending and is expected by November, followed by its first operational sortie early next year. Then, in deals that were signed in late-2017, AMF will assemble 50 Block 3 JF-17s and 26 JF-17Bs.

There is a lot going on to occupy the minds of the PAF leadership, and operationally the JF-17 is playing a major part in the defense of Pakistan’s skies, with six operational squadrons. During the PAF’s recent confrontation with the Indian Air Force, known in Pakistan as Operation Swift Retort, PAF Chief of the Air Staff Air Chief Marshal Mujahid Anwar Khan told AIN in mid-April, “The aircraft performed very well against the IAF Mirage 2000s and their Mica missiles, as well as the MiG-21 Bison and its R-73 Archer AAMs.”

On the export front, Aviation Industry Corporation of China (AVIC) has delivered six JF-17s (four single-seaters and two dual seaters) to the Myanmar Air Force, while PAC has sold three examples to Nigeria, and these should be delivered after the pilots are trained in Pakistan. Sales and marketing of the jet were split between PAC and China National Aero-Technology Import & Export Corporation (CATIC) in 2015.

More than 100 JF-17s have now come off the AMF assembly line, where the wings, horizontal tail, vertical tail, and forward fuselage, representing 58 percent of the fighter, are built. They are matched with the remaining 42 percent built in Chengdu in China, including the mid- and rear- fuselages that are airfreighted to PAC Kamra. The three fuselage sections are mated at the JF-17 subassembly line and are pushed through on a large trolley to one of the four docks in the final assembly facility.

That’s when the avionics, wiring, undercarriage, harnesses, and Klimov RD93 powerplant are added, while the Martin-Baker Mk16 ejection seat comes later. The aircraft’s air-to-air refueling probes are not necessarily fitted on the assembly line, although all the necessary plumbing has been put in place since the production of Block 2 13-129.

After being towed down to the flight test shed, the newly built JF-17s are put through five functional check flights (FCFs) by one of the four qualified test pilots based at the co-located Test and Evaluation Squadron (TES). Three PAF pilots have qualified at the Boscombe Down-based Empire Test Pilot School for the JF-17, but now most of them go to Xian in China to get their qualifications.

He told AIN, “During the FCFs we push the aircraft to the limit, right through the complete envelope, to assess the handling qualities, checking the systems and aircraft performance.”

Once the FCFs are completed the PAF then puts the JF-17 through a further check flight and if there are no snags, the aircraft will be officially handed over.

PAC chairman Air Marshall Ahmer Shahzad told AIN, “Production of subassemblies has already started for the first two 50 Block 3 aircraft, to be assembled next year, and will be followed by another 12 in 2021, 2022, 2023, and 2024.

The chairman said he is keen to build on this. The company has already built a high-speed aerial target and is close to the completion of an indigenous UAV.

BLOCK 3 JETS
The JF-17 Block 3 enhancements will involve new avionics, including a helmet-mounted display and a holographic wide-angle head-up display, better electronic warfare systems with integrated self-protection kit, as well as a missile approach and warning system, an increased payload, and more sophisticated weapons like a fifth-generation short-range air-to-air missile. It will be the ultimate JF-17, and with an AESA radar will have the capability to employ longer-range weapons and track multiple aircraft.

A decision on a new AESA radar for the Block 3s is expected to be made by the end of the year. There are now three Chinese contenders, which were all shown at last year’s Zhuhai Air Show, while Leonardo’s Grifo-E is still on the table.

The second contender, which was displayed at the Zhuhai Air Show last November along with the two Nanjing examples, comes from Leihua Electronic Technology Research Institute (LETRI), another air-cooling AESA known as the LKF601E. AVIC has thrown its weight behind this option and claims it was the first air-cooling radar. Replacing the JF-17’s original KLJ-7 is simply a case of taking out the old system and inserting the new one. The PAF’s Flight Test Group is currently working the options.

WEAPONS OPTIONS
The PAF’s JF-17s are operational with the SD-10 beyond visual range air-to-air missile (AAM) with a data link and initial mid-course guidance, PL-5EII infrared short-range AAM, C-802 anti-shipping missile, and a stand-off capability courtesy of its Indigenous Range Extension Kit integrated with the Mk80 series of general-purpose bombs. The PAF chief of air staff recently told AIN that the JF-17 is better than many contemporary aircraft in three areas but would not provide any more details, although the air-to-sea mode is undoubtedly one of them.

At IDEF 19, held in Istanbul in early May, an Aselsan source confirmed that deliveries of the first of 50 Aselsan targeting pods for the JF-17s will commence "within a few months," which will provide the JF-17 with a laser-designator capability, working with JTACs on the ground in the air-to-land integration role.

Air Commodore Rashid Habib, JF-17 deputy chief project director, told the audience at the IDEAS 18 Air Power Conference in Karachi, that the JF-17 had flown 40,000 operational hours. He added that the JF-17B would be fitted with a missionized rear cockpit for combat training and operations, a three-axis fly-by-wire kit, and a fifth-generation advanced short-range air-to-air missile.

4 years later, the JF-17/FC-1 visits Paris–Le Bourget Airport again...

Lol Chinese aesa. Pakistani used Saab eryie against Indian jets and kept Chinse place secure on ground as they were completely and utterly useless. Lol.

.. oh?
aerodynamically unstable ... relaxed static stability... blah,blah ,blah....

I'm just wondering ...so called 'aerodynamically unstable ' on which axis ?

sciolistic idiot.
Keeping wondering...... till eternity

the best which can be expected from a ignoromous

1. it seems you have to raise your question when PA get their new tank Finally, let's see what they choose in the end and When?....VT-4 is priced at over 5 million USD and the Ukrain competitor asked for around 3.5 million in that early bidding.

Unlike our tradional weapon buyer, Pakistan is a normal commercial customer .our Defence industry learned a lot in early International Competitive bidding and Contract performing...we often read some memoirs of the old generation of salesman mentioning this learning curve...nowadays , the new Gen and the Defence indsutry has new stategy. and we understand some international buyers better then ever.

since you are in the same subcontinent ,and used to be under the same Colonial Rule, maybe you could understand more than us...lol...I saw quite some similarity in your defence tenders.

2. we don't think PAF want another fighter similar to F-16 class...obviously , trying to get more F16 or having the F16 upgraded is more important and effective than setup a new system for a new same class/Generation fighter.

yes, J-10C got the permission and is offered to international market last year. it seems aiming the country east to your territory.

BLOCK 3 JETS

The JF-17 Block 3 enhancements will involve new avionics, including a helmet-mounted display(1) and a holographic wide-angle head-up display(2), better electronic warfare systems with integrated self-protection kit(3), as well as a missile approach and warning system(4), an increased payload, and more sophisticated weapons like a fifth-generation short-range air-to-air missile(5). It will be the ultimate JF-17, and with an AESA radar(6) will have the capability to employ longer-range weapons and track multiple aircraft.
on Airshow China 2018

(1). HMD...around 3 models in the catalog


(2).holographic wide-angle HUD...there is another earlier model on J11B/BS J10B/C.


(3). KG600


(4). NG MAWS on J-10C


(5). PL-10E


(6) two configuration of KLJ-7A and LFK-601E

Let me give you a typical French roasting...



So this thing is air cooled which is a joke for an AESA to begin with, but now you have an air-cooled AESA with two 500 T/R side-panels for extended coverage. Are you trying to get your radar to the same temperature as your engines?

How many of these are "OPERATIONAL"..... EVEN IF THEY BEGIN IT TODAY, it would require years to deliver these with an operational fighter.....

Look at the size of the aperture of those side panels, you seriously think that it has 500 trm on the sides;-) ;-) ..... Typical chinese food which promises too much and delivers little.....

LOL...yeah.....

Analog fbw = composite fbw ??? don't make up your own stupid theory...

'Analog' is relative to 'Digital'...Analog control signal or the digital control signal

typically, Su27 has the 'Analog fbw ' so has the early model F16. and F-15 has the hybrid electronic/mechanical system
-----------

FC-1/JF-17 is always called 'Hybrid Flight control'. the main architecture is based on the 'Digital Flight control computer'...but

in the pitch axis -digital full authority quadruplex FBW system
in the yaw and roll axis- hybrid electronic/mechanical system

on JF-17B/Block3, those two axis control was replaced by digital full authority quadruplex FBW system as well... here comes the three-axis digital fly-by-wire- the full digital FBW system

View attachment 35814
Roll and Yaw axis, it has analog fbw, while on pitch axis its Digital FBW, the setup is called composite system... That also suggest, the design is relatively stable at yaw and roll, as beggars couldnt pay for more computers which cost thousands of dollars . Now go through the earlier or days old comment, you will realise that i mentioned for the operational variant . the tweet is so false, the one who tweeted dont even know that every aircraft has three axis, called pitch, yaw and roll.... JF17B/3 is as good as nothing, none of you even presented a model of that junk and yet claim all puddings in the single cake....
