LCA was always a bad and a limited design !! It started off in 1983 and pretty much a failed copy of Mirage 2000. and mind you that comparing the LCA to the Mirage 2000 is like comparing a trout to an eagle in the sky !

DRDO messed up in every field when it comes to LCA :
LCA
has design problems which
will be fixed.
LCA
has Radar problems which
will be fixed.
LCA
has engine problems which
will be fixed.
LCA
has FBW problems which
will be fixed.
25 years and the saga continues...
What LCA has turned out to be shouldnt be a surprise to anyone. I am amazed that DRDO didnt forsee all this coming !!
Oh well, as things stand now, first (40) forty LCAs will be incapable of doing combat and are in the league of basic trainer Mushak and Medium trainr K8.
and yes, it is a very serious aerodynamic issue and not only an engine issue as you like to belive :
I'll give you a better idea. Pluck the figures in for LCA and you will get a very good idea where LCA stands :
A jet aircrafts' characteristics
wing span = 21.5 m
wing area = 43.7 m^2
fuel mass = 3,617 Kg
total mass = 13,777 Kg
engine tsfc = 0.45 NN/hr
zero-L/D coefficient = 0.016
Oswald efficiency factor = 0.834
Calculate: (at SEA level)
1, max L/D ratio.
2, L/D at max speed.
3, max range/endurance.
4, max speeds.
If you cant then just say so. I will stop further commenting on your posts.
If you can then I will take this debate much further.
