    Astra BVRAAM

    Total order is of 300+ missile, not 648.

    Astra BVRAAM

    Lots of research paper are available on it. But let me lay out the bare simple fact here. Rocket motors could be divided broadly into two types. One with high specific impulse which would give you huge thrust in very short duration. Second is low specific impulse which would give you...

    Astra BVRAAM

    Max range of Astra Mk-1 = 110 km Max range of Astra Mk-2 = 160 km (not official) Change in % = 45% In case of Derby. Max range of Derby = 50 km Max range of Derby-ER = 100 km Change in % = 50% So you could see that the result of using dual pulse rocket motor is same in both case. Dual pulse...

    Astra BVRAAM

    Why you think it would be anydifferent? Just compare Derby and Deby-ER. Both are dimensionally same with only the difference in propulsion.

    Astra BVRAAM

    May be few people here could now lay in rest after incessant crying.

    Astra BVRAAM

    Yes. But I believe before him Albert Fono proosed and even designed RAMJET. Anyway the time line for its study is almost similar for all.

    Astra BVRAAM

    That's pulse jet. But RAMJET was first proposed by Hitler's scientist I believe.

    Astra BVRAAM

    Yeah, Subsonic flow and Supersonic flow of air in combustion chamber.

    Astra BVRAAM

    RAMJET is not subsonic, but it do work in subsonic speed. Infact studies has been done on cheap subsonic RAMJET engines to power drones. Although it looses its efficiency in subsonic speed. But the speed I meant in DMR is air speed.

    Astra BVRAAM

    Ramjet only works in Subsonic and Supersonic flight. In Hypersonic flight, you would need SCRAMJET. A Dual Mode RAMJET is one which works in both subsonic and supersonic speed.

    He means DMR.

    Astra BVRAAM

    Yeah, DMR. Chinese are good at playing with words. DMR doesn't increase range per se. It only enables a RAMJET engine to perform at subsonic speed along with supersonic speed. So technically you don't require a rocket motor to boost the missile. But Chinese sure would increase the range by...

    Astra BVRAAM

    But what is a Dual Ramjet? Make me understand that first. You might be either talking of Dual Intake RAMJET or Dual Pulse Motor or Dual Mode RAMJET.

    Astra BVRAAM

    Yeah, I got it.

    Astra BVRAAM

    You mean dual intake RAMJET. Not dual RAMJET.

    Astra BVRAAM

    Dual RAMJET? What is that?

    Astra BVRAAM

    They are integrator, just like HAL in case of Tejas. Infact BDL is lead integrator of all missiles in India.

    Astra BVRAAM

    Exactly. IAF never ordered LSP for Tejas nor IA/IAF ordered LSP for LCH which DRDO/HAL also confirmed. But on other hand when DRDO confirmed that they have received order for LSP of Astra, you started comparing it with LCH and Tejas. So who is ill informed ?????

    Astra BVRAAM

    It can be and its work in progress. But at 150 kg, its 32 kg heavier then Derby. Hope that doesn't effect the performance of Tejas.

    Astra BVRAAM

    Could you point me out where is the order placement for LSP been given by IAF in these two reports? All I could see is the project cost published by ADA. Where ADA mentioned that IAF has placed order for LSP Tejas? I could give you proof of where DRDO specifically mentioned getting order from...
