A Multi-pulse Thrust Adjustable Solid Thruster

Abstract

The invention discloses a multi-purpose solid propeller with adjustable propelling force. The multi-purpose solid propeller comprises electric-control solid propellant units, an outer electrode, innerelectrodes, an insulating layer, a heat-insulating layer, a combustion room and a spray tube, wherein the outer electrode is arranged in the combustion room; the outer electrode is uniformly distributed with a plurality of circular-hole spaces on the basis of one integral metal cylinder for separately placing the plurality of circular tube shaped electric-control solid propellant units; each inner electrode consists of a plurality of metal cylinders which are separately embedded into the corresponding circular tube shaped electric-control solid propellant units; and each electric-control solid propellant unit is in tight contact with the outer electrode and the corresponding inner electrode. According to the multi-purpose solid propeller disclosed by the invention, each inner electrode isconnected with the outer electrode to form a control circuit, and each circuit is controlled to open and close, so that ignition, combustion and flameout of each electric-control solid propellant unit are controlled. Voltages at the two ends of each inner electrode and the outer electrode are controlled, so that a combustion rate of each propellant unit is controlled, and therefore, in each working pulse, propelling force of the propeller is adjustable.

Description

technical field [0001] The invention relates to a propeller using an electronically controlled solid propellant, in particular to a multi-pulse, thrust-controllable solid propeller, which belongs to the field of solid pulse motors. Background technique [0002] Solid rocket motors are difficult to achieve multiple starts, and the thrust is difficult to control. At present, the thrust-adjustable solid engines mainly include solid engines with adjustable nozzle throat area, segmented charge prefabricated multi-stage thrust engines, solid pulse engines and extinguishable solid engines, but none of these engines can achieve continuous multiple starts And thrust active random control. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a multi-pulse thrust adjustable solid propeller, which is easy to use and obtains multi-pulse and adjustable thrust. [0004] The object of the pre...
