Tejas Mk2 (Medium Weight Fighter) - News and discussions

why so salty?
I am not being Salty. Even DA had to redesign the nose of Rafale to make it compliant for deck ops regarding frontal visibility. As the wing sweepback angle increases, the Alpha to generate adequate lift also increases. LCA config for TEDBF is ultimate mistake. LCA already has a long nose and pilots flying it on deck will face serious visibility problems when they are not within the envelope for landing. trying to correct for the approach mistakes during landing on deck, they may hit an alpha which can make the deck disappear from vision. It is very common when we are just abot 100 feet from touch down and we need very rapid stick movement to keep the aircraft on meatball. Going blind at that time even for a fraction of a secons can be disastrous and that will happen in case of TEDBF if it uses the LCA configuration.
Test pilots landing LCA on deck does not mean that aircraft is safe. It will be flown by pilots who are not Test Pilots. AND they may not have the skills of a test pilot everyday, every flight. Hope you know about Bio-rhythems?
 
The weight gain on Mk2 due to larger size is being offset by an engine which delivers just extra 8KN of thrust. We will end up with even poor TWR for MK2 than what we have for MK1A.
TEDBF is LCA MK2 with twin engines and same configuration which has 50*/62.5* swept compound delta. No deck based fighter has ever been made with such high sweepback angles. Now what we will have is that we will get an aircraft with oversized engines which will result in suboptimal performance of the engines resulting in poor range. The aircraft size/weight has to be optimised for the engine used as a jet engine has best SFC at about 87% thrust. If the engine is operating most of the time below this thrust rating, it will have poor SFC which will result in poor range. Its like putting a truck engine in Maruti Alto.
Sir, I am confused. As per the article in delhi defence review the empty weight of tejas mk1 is 7040 kg and empty weight of mk2 is going to be 7000 kg. So mk2 is 40 kg lighter. Maximum wet thrust of Ge404 is 85Kn as per GE website. So how 15% increase in thrust will be insufficient for 40 kg lighter plane?
And if we see wiki then empty weight of mk1 is 6500 kg then mk2 is 7.6% heavier but still it has over 15% more thrust.

Mujhe Kuchh samajh me nahi aa raha.

The Mirage 2000's specifications are not so bad for an old aircraft! They have nothing to envy compared to the others.

France should offer to sell at least 20 Mirage 2000 along with the additional Rafale deal , at a discounted price of course

We are buying 21 more MiG 29s
20 more Mirages would be very useful to us 🤣

Wait ,regular pilots are not skillful as test pilots? Are you joking?
 
Some programmes launched by HAL only aim at thwarting the arrival of the Rafale, they do not aim at achieving a result. I don't think the operation will succeed.
Why only Dassault can play dirty?

Is that why Dassault crawling back to HAL according to new reports?

Test pilots are selected from regular pilots because the job needs even more skills and presence of mind.

I think this is correct.

shud be some mistake
LCA Mk2 shud be higher weight than LCA 1,
yes the plane has been made lighter, but also it has been made longer and that needs material.

LCA MK1 is 6500kgs, LCA MK1A is supposed to be 500-1000kgs lighter than LCA MK1 even if they reduce 500kgs it should be around 6000kgs and LCA MK2 weight target is around 7000kgs....
 
MK 2 update

Dr. Rao looks clueless in the interview. Typical old promoted to post where he has no vision or energy. He has one project under him and can't remember the timeline of MK2. No wonder ADA people are lying to the nation.

Lol, He is not clueless ...I think some people are not good at communication but good in their technical field also it may be due to the fear factor of heading a govt defense project. I think these interview questions are prepared prior to the interview and Dr. Rao just reading them from the paper on the desk.

Exactly, most of the ISRO scientists are like that too.
