Re: AMCA News and Discussions

Two things wished for the MCA that may be futuristic in value are: 1) If the vertical stabilizer is the size that it is, then every opportunity should be taken to fill it up with fuel, to optimize on endurance when i posed the question - why are you not considering all moving V. stabilizer? to a hi...

The vertical fins of su30mkk are claimed to have fuel tanks.... Wow, that's news! So it does confirm that the plumbing is indeed feasible, on one of ours going forward. Too bad though the MKI doesn't have it but the MKK does and it's not even listed as of now, on future upgrades. Auxiliary fuel can...

Then why do the wings have sharp tips?[/quote] @indranilroy: All trailing edges are sharp aren't they. They usually end as a part of the airfoil. Whether it is the stabilizer or the wing, they end with a very blade like form. I haven't seen anything out there that has a thick, blunt sort of cut-off...

Re: AMCA News and Discussions

My questions are of a different kind ... why are the edges rounded on the stabilizers? By the way, I did not like the AMCA design initially, but it is starting to grow on me :-). Speculating more than anything else at this time: edges could be rounded because of better manufacturing efficiency, cou...

Re: LCA News and Discussions

Fly up to about 12,000 feet or less and you can manage without O2 for the duration of your fuel on-board. But it's not practical, since you'd want to cruise at 40,000 ft.> to your target/destination.

There was an unconfirmed report sometime ago, that there were structural issues that surfaced for the IJT during coupling tests. Won't be surprised if it's back in the design bureau. AL-41 integration was completed and there were no issues there apparently.
