The crux of matter here is that in a coast mode , manuverability is diminished, and I am pretty sure you are going to agree on this. Thats what is being said all along. You originally started with AAM DO NOT COAST . Now that you agree they coast after burnout there is nothing more to discuss. If I ...

Change in Velocity, delta V = 10 x Specific Impulse x LN m/s This assumes that all the fuel is used to get the missile as fast as possible and none is used to provide just enough thrust to sustain a given velocity. In otherwords, it assumes an all-boost motor NOT a boost sustain motor. AIM-120A AMR...

SAMs and AAMs are coasting when they finally engage a target unless the target is well within range. they still manage to keep up with the target because at this point they have a velocity comparable/better than the target aircraft while they have a much higher maneuverability capability than the a...

It doesn't work that way! For instance the AIM-54 had a motor burn of ~27 seconds, with a range of 180+ km, and peak velocity was mach 5 calculate for yourself mach 1 = 340 m/s (@ SL) mach 5 = 1700 m/s (@SL) Even if we assume the missile reached mach 5 the instant it was released it would be only 4...

How would it maneuver unpowered? Is this a recognised technique? Sorry, I dont know much about AAM's. yes, most SAMs/AAMs burn all their on-board propellant in the first few tens of seconds of flight to gather max energy and thereafter is on an un-powered ballistic trajectory to the kill box. this ...

A case of bad Prithvi, a retest should take care of it.

The mission control centre computer found that the interception was not warranted and accordingly did not allow take-off of the interceptor missile. The cause of the target malfunction is being investigated by an analysis of telemetre data,' the official said. I think we can take some Solace in the...

ankit-s

IMHO, Prithvi cannot fully mimic the flight pattern of an IRBM. IRBM's have a reentry vehicle and their terminal velocity is also much higher then Prithvi. Also, their tracking might be different (in my opinion) as tracking a reentry vehicle is quite different from tracking Prithvi. Agni I should b...

At 200-250 Kg its not worth wasting Agni III, does not make economic sense because per Kg launch prices have come down anyway. How did you arrive at above?

Not so fast. Based on my rudimentary understanding or orbital mechanics and satellite launch, all satellites need to placed in orbit with an injection velocity to enable their progression on the orbit. So you can't load the missile upto its gills. Another factor is the size of the satellite, since ...
