Very nice pictures. There is indeed a strake added to the nose of the plane and another to the tail.

This was done after the crash. Was there certain issues identified with the design?

Good looking plane this one.

Is the LSP-1 fitted with the Saturn AL-55I?

finally, it looks beautiful.
More of these and we will not need that "murga" bae hawk.

Is the flight profile supersonic at all altitudes, what is the approach velocity, payload.

Actually really nice.

Hi,

I have the same question as Gagan. Could any experts comment on the addition of the strakes and how exactly it effects/modifies the aerodynamics of this aircraft?

Thanks for the pics Shiv. Details please, if possible, on when will the 12 LSP's be delivered?

Cheers
Robin

Shiv, Nice Pictures. Thanks cause your pics are always on my desk top`s....
When it comes to good pictures, you zoom ahead of everyone in league...

Please keep it up.

Gagan, Sajay ....
In general strakes serve two purposes, (1) to improve directional stability, or (2) to generate turbulent air at high angles of attack which improves controllability at such attitudes. I think that these changes have been made to the Sitara for the second reason. At high-AoA, the elevators on the tail would have been 'blanked out' by the wing and the engine intake. These strakes would alleviate such a situation.

Daanish ...
The Sitara is a purely subsonic design. It will just barely (if at all) push through the transonic regime, supersonic is out of the question. This is a good thing. Supersonic is well and good in combat aircraft or trainers, but subsonic aircraft with straight wings are perfect for new pilots. Also the aircraft will be cheaper to operate, thus (hopefully) cadet pilots will get more flying hours before graduating to more advanced aircraft.
