Re: Indian Missiles News & Discussions - 17 Dec 2018

Booster was at least today to carry the missile to required altitude and speed (as if mimicking a fighter plane) and then let go as a plane will let go sfdr. On plane do we need a booster? From ramjet to work is there a high initial velocity? Don’t know Yes there still needs to be booster (smaller ...

First flight of SP 20 in about a week's time. Delivery of 18,19,20 expected in 2-4weeks. So that's 4 a/c this financial year. Hope the pace picks up. What they were licking during this slowdown is that once the aircraft has flown, it will clear acceptance trials within a fixed amount of time. And o...

I make a guess. Astra Mk2 will be operationalized by end of 2022. The propulsion is mastered. The seeker is mastered. I don't see how it will take more than 2 years. Also, I expect SFDR to be operational by 2025.

Q1. You can't ignore the DSI. DSI intakes would always have the outer lip ahead. The opposite is true for splitter plates. Can't go into the details. Q2. Not ideal for RCS. Must have been an aerodynamic need. Q3. That wing is ideal for RCS, not ideal for aerodynamics. In this compromise between stea...

1. Air brakes will be carried forward. 2. The spill duct over the wing will also be retained. But it is not for added airflow over the wing (that's a very small amount of lethargic boundary layer. The major gain is that it energizes the airflow over the wing and keeps it attached for longer. The ori...

Brahmos A can be optimized significantly. But I have been hearing about brahmos mini and NG for so long that I have given up hope. This is what happens when you don't have design autonomy.
