Re: Tejas Mk.1 & Mk.1A: News & Discussions: 23 February 2019

Year end is March 2020. Not December 2019. They have been scaling up their production and should have the second assembly line ready so that the numbers can reach 16 per year. By 2023, they are targeting upto 24 per year, so it is a gradual build up, not something that's happening in just 9 months....

Re: LCA: News & Discussions - October 2016

Where did you see the 600 kg weight reduction claim? What I had read on IndiaStrategic was that the overall weight gain would be ~50 kgs, since 200 kg ballast in the nose would be gone and a 250 kg AESA radar and its back end would go there in its place You need to consider weight removed as 200(ba...

You are right at that, my bad. But since I have not read about actual max actuation rate per second for LCA, I wouldn't comment on that. But 2Hz seem low to me (Is this for LCA?). In one of the papers on LCA, one type of dynamic instability is shown to have 200ms time period to double amplitude, th...

That's a crucial point that IN and many people ignore in favour for "indigenous" developments. N-LCA is dependent on the MK2 upgrade, so unless that is done, not a single N-LCA MK2 will be available for our carriers. It is even safe to assume that even IAC 1 will be inducted, before N-LCA...

Still some confusion around the dry weight of the LCA. Shiv has quoted 6950 whereas KrishG is quoting 6550. Can we please get a definitive answer before the AI 2011 is over. 6950 may explain some of the payload limitations being discussed earlier.

Not that it matters much, but, I am not convinced that the Russians would like to deal with the RCS issue as much as the US. I get the same feeling.

On the second question, my guess is that the current alloy used may not stand at all when the inlet temp is raised to 1800 deg, practically ruining the core, which is probably why higher thrust is not demonstrated yet. 1400 to 1800 is a 400 deg C range, so will we see increased thrust at say 1600 d...
