ADA Tejas Mark-II/Medium Weight Fighter

[Holy Triad]

What is the status of CSIO HUD MK2. Why Lite Hud was chosen for MWF,will this mean that LITE HUD will forever be on MWF and all the claims by CSIO regarding this technology will be go in vain?????anyone can answer....

I'm not sure of the variant,but this might answer yo question,(dated Feb 29,2020)


The Central Scientific Instruments Organisation (CSIO) today transferred the technology for manufacturing a new variant of head-up display (HUD) for the Tejas fighter aircraft to Bharat Electronics Limited (BEL), Panchkula, for commercial production.

Is this HUD is holographic type or conventional type?

Their are two type of HUD ,refraction and diffraction hud, diffraction hud is called HOLOGRAPHIC while refraction HUD was what on Tejas mk1 and CSIO developed,that's why I asked for the mk2 variant which CSIO said was under development..

It is a modification on mk1 hud,CSIO had sanctioned a different mk2 project.,.

So holographic one is under development, most probably

 

[HariPrasad-1]

Cockpit, sensor fusion, mission systems, sensors etc are from AMCA R&D coming to MWF

RAM paint will also come...............

Ok, the project is in limbo I guess,



You might already know this,but posting for other members to see,

Csio website says mk2 is an ongoing project,

MWF size difference with AMCA (adjusted by matching F414 nozzle's size).

It seems almost unbelievable how these two have very similar net payload of ±6.5 ton... Imagine how much & far its beefed-up brother of doubled thrust like AMCA, will be capable of hauling with extra fuel instead of weapon bays!

Well amca will carry almost double the fuel internally to mwf. 6000kg+ compared to 3300kg for mwf.
Amca will also carry way more sensors and instruments compared to mwf .

Yeah duh, it's so much bigger... But if ORCA is indeedva MWF on steroids, based on AMCA fuselage (on that at ORCA thread) & not inherit its weapon bays, then you're looking at upto 1ton more internal fuel, plus payload increase.

Nicked a screenshot from that video of @Kuntal. Other than this there is not a single topview of MWF anywhere on the Internet.

 

[Mikesingh]

The ORCA is probably the Tejas Mk 2 known as MWF (Can't these guys decide?) with extended fuselage to accommodate the bigger F414 engine and the addition of canards. With cutting edge avionics with the Uttam AESA, multi-sensor data fusion and so on, it's like designing an entirely new aircraft from scratch except for the same Delta wing config.

MWF is the final iteration of Tejas Mark2. ORCA is a separate proposed concept, which is practically a MWF on steroids.
Link to ORCA thread.

Originally arose from Navy's requirement of a twin engined deck based fighter or TEDBF, the idea is for fuselage to be extended & expanded to fit twin-F414 engines.
My personal opinion, it is most likely to be the existing AMCA fuselage with Tejas delta-canards... I don't see why they will work on a non-stealthy one when a better platform is already available for modifications.

There are advantages of non stealthy aircrafts too ....like better performance , more capacity to carry weapons , more endurance . Better range ......it is cheaper to built , cheaper maintenance and operations .
This is why all countries would built and use non stealthy aircrafts along with stealthy aircrafts in the near future .
They would have to design an entire new jet fighter along with new control laws .

Yeah, agreed. Those points have been discussed to death in the ORCA thread, with people who were questioning the requirements of ORCA with AMCA & MWF in picture.

They would have to design an entire new jet fighter along with new control laws.

But this one works both ways.

Which one do you think will be easier?.. Superimposing Tejas Mk2's delta canards on existing AMCA twin-F414 fuselage that can carry 6ton fuel, to move on to optimisations... Or to drastically alter the MWF platform by enlarging it enough to fit 2 engines, with room for extra fuel, all while keeping in mind performance parameter deciders like CoL or shifting CG & then do rigorous work tons of minor aerodynamic tweakings?

That^? Or this jet with decent degree of inherited frontal stealth?

Positioning of canards and shape and size of the air intakes matter a lot in designing a combat aircraft. The main changes made in MWF from its base line aircraft are the addition of canards and changes that have to made on the shape and sizes of the air intakes in order to cater the needs of the more powerful f414. Canards have to be positioned to the aircraft not to obstruct pilot's view or override/overlapped the main wings. In order to add some frontal stealth to the aircraft it needs to incorporate a retractable refueling prob instead of the protruding one and the canopy needs some paint jobs to remain stealthy, that tecnology has not been developed as yet even for AMCA and more over they should developed body conformal antenna. These technologies are the basics and no one will give you technologies you have to developed by own effort and canopies are to be coated with a thin layer of Indium Tin Oxide (ITO), which gives it a golden tint.

canopy has been developed way back in 2006.

See old posts m8.
MWF will very likely have retracting fuel probe, as well as semi-stealth (stealth feature that can be incorporated in classic design, like in F-15SE) as per reports. AMCA definitely will, never seen any external probe on any design render. Plus there is atleast 5 more year's time before they arrive.

I don't see any ORCA couldn't inherit those from both patents, especially if its to operate in post-2030 scenario. ^Its front silhouette look quite like J-20, no?
If the internal bays stay, then with external stealth weapons-pod, then you're looking at considerably stealthy A2A config, with max 3+4+3= 10 AAMs.

Had some spare time in my hands, so I updated the Wikipedia page of Tejas Mark 2 MWF... Check it out.

Suggest content I may have missed out.

Good job .
