Re: Naval Tejas Mk1/Mk2: News & Discussion - 23 February 2019

ADA is pitching NLCA as a LIFT for carrier landings, in line with what the USN does with Goshawks. NLCA is certainly much more capable than a Goshawk. NAvy has not evinced any interest as of yet. NLCA Mk2 is being completely redesigned. It won't be Naval AMCA, but a twin engined NLCA Mk2. Frankly, I...

Tens of landings. All the tests that they did at SBTF since the first trap will be repeated on the carrier. Same with take offs.

But the duration will be shorter as they dont have to wait for favorable wind conditions.

Re: Tejas Mk2 Medium Weight Fighter: News & Discussion - 23 February 2019

The EPE is actually not larger than the 414IN. It is supposedly a drop fit for aircrafts designed for the 414. It is advertised that no changes on inlet would be required either. But I dont understand how that's possible. Both engines have the same dimensions and pressure ratio, but the airflow of t...

Re: Chandrayan-2 Mission

Heartening. This fuel module is an interesting take. What has been revealed is that the lander module was designed to handle a certain amount of deviation. Increasing this tolerance would have increased fuel capacity. So this fuel module is to allow more flexibility.

Will it be launched using GSLV2?

Picklu ji, NLCA cannot be doing 7.1 m sink rate on shore because the SBTF is not steaming at full speed into the wind. Also the NLCA would never be doing a 7.1 m/sec unless the aircraft hits a air bubble just before landing and the ship is heaving and pitching at the same time. NLCA traps are at ful...

Re: Advanced Medium Combat Aircraft: News & Discussion - 30 August 2019

Actually, it is clear that IAF is deeply onboard with the AMCA program and the AMCA design goals are kind of laying out IAF's vision of the plane. It's primary role is air superiority. You can see that from the fineness ratio, targeted and TWR. They have traded payload and range to gain this perform...

F-35A does not have a supercruise requirement and the key metric is thrust minus drag (dry thrust). KFX with those F-414's will be limited in its speed. I think once it matures, you will see that reflected in its performance envelope. That's a very valid statement. That F35A's performance numbers a...
