SD10 second pulse

[shaHeen-1]

Is it supposed to fire immediately after the first? I would expect it to wait a bit depending on range to target to fire again to conserve efficiency. For example, for a long range throw, I would rather like it to stay near Mach 2 for much longer than just spike to Mach 4 at the start and lose much of its energy to high speed drag.

 

Maybe I'm wrong. Not a PAF expert.

According to Deka later variants are dual pulse, the SD-10A is dual stage but not dual pulse

[shaHeen-1]

For give me but what's the difference?

[AeriaGloria]

Dual stage= there are two stages, in this case a boost followed by sustain stage

 

Dual impulse = can choose to fire each stage separately, this is likely how the AIM-120D gets its range, by firing second stage very late for slowest average speed and drag

[shaHeen-1]

Ah so for the first one the two are glued together and can't be separated?

I don't know about the SD-10A specifically, but just dual boost is what AeriaGloria is saying.

Is dual stage modeled in DCS?

Unless my eyes deceived me, there was a clear break in the smoke plume on launch last time I chucked a couple.

Dual thrust is a boost-sustain motor, it do not need a second ignition which is difficult for the solid rocket. Dual thrust use different fuel burning speed or burning surface for boost-sustain thrust.

 

Dual impulse motor need a second ignition and usually ignite the second stage near terminal phase, thus increase the average speed and terminal energy for the missile to intercept high maneuver targets like fighter.

All multi stage missiles in DCS do this
