Abstract
PURPOSE: To contrive not to have the nozzle closure blown backward when a rocket bomb is blasted forward in such a way that a nozzle closure of a rocket bomb is made into a form so as to be taken out of nozzle at slow speed right after blasting off.
CONSTITUTION: A nozzle 11 which is provided at the rear end of a rocket motor 4 is closed by means of a nozzle closure 20, and the nozzle closure 20, is integrated by a closure part 21 on the slot side, a closure part 22 on the rear side, a coupling part 23 and a throttle hole 24. When firing power is ignited, at the same time as its combustion gas separates a rocket bomb 1 from its cartridge, it penetrates through the throttle hole 24 into a space 27, so that the inside of the space 27 becomes higher pressure than atmosphere. The instant the rocket bomb 1 blasts out of a gun, the nozzle 11 is exposed in the atmosphere, and pressure difference is produced between it and the space 27. Since area in the inside 22a of the closure part is larger than that in the inside 21a, the closure part 22 undergoes larger thrust than the closure part 21 does. In consequence, the nozzle closure 20 is taken out of the nozzle at slow speed.
