ADA Tejas (LCA) News and Discussions

[Bhadra]

another white elephant in the long list of failed projects

Do not say so in this forum or you will be marked .....

 

[ersakthivel]

EXACTLY. You have the answer in the very sentence.



I already explained so even a baby can understand. What does that make you?

Quoting from post #52.


Now do you understand? Why do you think I told you re-read #52? Go read it again. Babies need to learn by rote. So, mug it all up.

The rest of your post is nonsense as usual since you were not able to understand #52.



Read #52 again. Your answer is there.



Lower speed != poor design. Less than optimum air = poor design. Therefore, F-35 != poor design. LCA = poor design. Something that can never be fixed on the LCA Mk1 for obvious reasons.

!= means not equal to.

All kinds of intakes can supply air to engine if designed properly whether fixed or DSI or splitter plate.

So from your numerous posts on the subject I know for sure You don't have any explanation to the contrary.

SO lets set aside this mug up learning method of babies as I don't need it

Since you can not post any convincing theory material to save you life in this subject, I leave it to other posters to arrive at judgement.

SO what does your friend at ADA says about the air intake of LCA TEJAS MK-2?

WILL IT BE

1.VARIABLE INTAKE or

2.FIXED INTAKE or

3.DSI INTAKE ?

So with what type of the above intakes ADA proposes to increase the top speed of tejas mk-2?


Since you have already established that FIXED AIR INTAKE IS NOT GOOD ENOUGH TO LET TEJAS MK-I FLY BEYOND MACH 1.6
and
TEJAS MK-I WILL NEVER REACH MACH 1.8 AT SERVICE CEILING AS ADA CLAIMS IT WILL,

So an effort to design a variable inlet that excels in mig-21 and mirage -2000 must be under way ,So please get some clarification on this redesign with ramp up or DSI or variable intake?

But till now ADA has said that

JUST WITH THE ENLARGEMENT OF 5 PERCENT INLET AREA THEY CAN POWER TEJAS MK-2 OVER MACH 2.
wHAT ARE YOUR THOUGHTS ABOUT THAT?

[ersakthivel]

Any more discussion on air intake can be had at TEJAS -IV thread below
http://defenceforumindia.com/forum/indian-air-force/43717-ada-lca-tejas-iv-29.html#post646481
This thread is there for that purpose.
This is engine thread and we can leave this thread alone till we get the final official confirmation of engine thrust level on mk-2.

 

[p2prada]

SO what does your friend at ADA says about the air intake of LCA TEJAS MK-2?

Why do you need to know that? Anyway, I wouldn't ask such a stupid question. It is unnecessary.

TEJAS MK-I WILL NEVER REACH MACH 1.8 AT SERVICE CEILING AS ADA CLAIMS IT WILL,

We will see. It is a paper requirement. Reality is different.

Theoretically, the inlet design allows mach 1.8, but practically achieving such an objective has failed, unless some magic happens with the weight. LCA has never demonstrated a speed above Mach 1.6.

So an effort to design a variable inlet that excels in mig-21 and mirage -2000 must be under way

Tell, me. Why do we need such speed?

JUST WITH THE ENLARGEMENT OF 5 PERCENT INLET AREA THEY CAN POWER TEJAS MK-2 OVER MACH 2.
wHAT ARE YOUR THOUGHTS ABOUT THAT?

Mk-2's final design, we will see when it comes. Read post #52 and you have your answer. Read it again.
Post #52:

So, there is a chance we may see greater mach speeds with a 100-120KN engine on LCA (if there are no major weight gains on the aircraft), but that again depends on the inlet design which can handle accepting a greater volume of air.

Answer just one question of mine.

Before you write your reply, do you actually even read my post?

Just answer this one question. I don't care about the rest of the nonsense you keep posting.

You can do that favor for other members of the forum.
Not for me.
I never considered this irresolvable inadequate air intake will stop the engine from achieving the intended thrust level.it is you who first said that
1.Lca wont cross mach 1.4
2.Then it is limited to mach 1.5
Finally now it is limited to mach 1.6 only at some flight profiles

DO YOU THINK THAT IT IS SUCH A SIMPLE STUPID QUESTION?
It seems very important since you have certified that inadequate intake design is the flaw in mk-1,
Isn't it fair to assume that ADA is changing the design for MK-2 or still they don't know what you know?

We will see. It is a paper requirement. Reality is different.

What is reality?
.ADA's claim and HAL's claim that each LSP is refined to achieve better performance,
flight envelope is not opened fully yet to validate extreme air to air parameter,
Or
Your past claims that LCA is stuck at AOA of 16 deg and top speed of mach 1.4
And your present claim that unresolvable difficulties in MK-1 intake will stop it from reaching mach 1.8 in service ceiling?

Theoretically, the inlet design allows mach 1.8, but practically achieving such an objective has failed, unless some magic happens with the weight. LCA has never demonstrated a speed above Mach 1.6.

So please ask your friend at ADA what is stopping this theory from being executed in reality.

Tell, me. Why do we need such speed?

Because it was the design spec agreed upon by IAF and ADA , you should ask them WHY?

Mk-2's final design, we will see when it comes. Read post #52 and you have your answer. Read it again.

MK-2's air intake design is not finalized according to you and your friend in ADA?

So no one knows whether it is going to be,

1.MIG-21 type with radar at the center,
2.Or mirage -2000 with a conical object in the center,
3.Or DSI intake like the one present in the JF-17
4.or F-16 type with oval shape under the fuselage,
5.Or just the same intake as tejas mk-1 with 5 percent increase in inlet are as per ADA's statement?

It is being built or not?

Boeing's Super Hornet seeks export sale to launch 20% thrust upgrade

The 'enhanced durability engine' becomes the 'enhanced performance engine' when you put the fan on it," Gower said.



The improved thrust would likely be most welcomed among militaries operating in hot weather, which reduces engine performance especially at a takeoff.

Despite the dramatic thrust increase, the EPE would not require enlarging the F/A-18E/F's engine inlets to enable increased air flow, Gower said.

"We are not modifying the mould line of the aircraft," Gower said. "The current inlet gives us enough [air] in-take."

For people insisting that LCA Tejas can not be used in mixed fighter group tactics the following is a good read.
Draft copy of the exercise Cope India report says:

Among many fourth generations attributes added to the IAF MiG-21Bison design, the incorporation of HMS (Helmet Mounted Sight) and high-off-boresight R-73RDM2 NBVR/WVR (Near Beyond Visual Range/Within Visual Range) AAMs (Air-to-Air Missiles) have turned it into a "Great Equalizer" in the WVR combat scenario. Conceptually a small number of MiG-21Bisons maintaining "radar silence" can be guided towards their aerial target by a couple of Sukhoi-30s by secure data links in accordance with MFFC (Mixed Fighter Force Concept). Upon entering into an WVR combat envelope the MiG-21Bisons armed with HMS and deadly NBVR/WVR missiles had the capability of destroying even fifth-generation fighters alike F/A-22 Raptor as assessed by high-profile Fighter Analyst Ben Lambeth of RAND Corporation. According to Lambeth "in visual combat everybody dies at the same rate." F/A-22 also has to slow down if forced into a WVR combat scenario and loses the advantage of its super-cruise attributes. The situation further complicates if the IAF Sukhoi-30s have acquired the capability of providing target illumination for RVV-AE (AA-12 Adder) BVR missiles being launched from IAF MiG-21Bisons at extended ranges.

Eventhough claims vis a vis F-22 is hard to digest this report indicates mixed fighter groups are norm rather than exception.

Is this the same engine that is gonna go into Tejas MkII??

There are no concrete info.But it is definitely going to be a baseline variant of EPE with thrust in excess of 100 kn.
