Transient detonation pulse engine and radial multi-pulse thrust vector device

Abstract

The invention discloses a transient detonation pulse engine and a radial multi-pulse thrust vector device. The engine comprises an engine body, wherein the two ends of the engine body are provided with a nozzle sealing body and a end socket body, a reinforcing sleeve is installed in the engine body, and an insulator is arranged on the inner side of the end socket body; the reinforcing sleeve is filled with a high explosive; a plasma igniter and mixed igniting powder are mounted in the insulator, and an electrode A and an electrode B are connected to the plasma igniter; the plasma igniter and the mixed igniting powder are combined to form a micron-sized line-width bridge foil energetic plasma igniter device; and the radial multi-pulse thrust vector device comprises a metal body and a plurality of transient detonation pulse engines evenly distributed in the radial direction of the metal body. The working time of the transient detonation pulse engine is shorter than 30 milliseconds, and the transient detonation pulse engine can work in the environment of high overload and the environment that the rotating speed of a flying body can reach 300 revolutions per second.

Description

technical field [0001] The invention relates to a high-speed rotating aircraft used in barrel launching, in particular to a transient detonation pulse engine and a radial multi-pulse thrust vectoring device. Background technique [0002] The basic principle of radial pulse jet direct force control is to arrange multiple pulse engines near the center of mass of the projectile, relying on the radial reaction control force directly generated by the high-speed gas flow ejected by the pulse engines to quickly correct the flight trajectory of the projectile. This correction method has the advantages of simple system and low cost, and is a common system for the intelligent transformation of conventional barrel-launched aircraft. [0003] The basic structure of the pulse motor of the existing charge is as follows: figure 1 Shown, be by engine body 10, rocket grain 10-1, grain baffle plate 10-2, end cap 10-3, electric ignition powder bag 10-4, porous grain dividing plate 10-5, elect...
