Sir if you think there are 2 physical motors in dual pulse motor missile. You have absolutely no idea what dual pulse motor is.If PL-15E doesn't have dual pulse motor , then it's more rubbish than i thought.
Dual pulse doesn't only increase range, it also helps in sustaining kinetic energy while maneuvers and terminal phase.
The missile uses the second motor as close to the target as possible.
That means the missile has a motor burning, when it needs thrust the most, at the last moments when it's twisting and turning to catch the target.
It's basically a technique to avoid expensive and complex stage separation mechanism which will have to be there in case of 2 physical motors. Instead, dual pulse motor rockets uses 2 kinds of propellants. One is fast burning producing higher thrust and is placed near the nozzle of rocket while other is relatively slow burning helping in sustaining the speed of rocket while ensuring longer range, and is placed farther from nozzle. There is a PSD in between the two but no physical separation takes place like in septation stage rockets we see in space or Ballistic missiles applications. A dual pulse motor is a single motor with 2 pulses.
PSD = Pulse Separation Device. It's an internal mechanism for ensuring that two propellants don't get mixed.
Thank you.
