Catapulting engine

Abstract

The invention relates to a catapulting engine. The catapulting engine comprises a shell body, charging assemblies, a rear top cover, a spray pipe, an igniting device, a volution, a front bolt, a rearbolt, a from top cover sealing ring, a rear top cover sealing ring, and a spray pipe sealing ring. The catapulting engine has the advantages of large increased area ratio, simple structure, mature process, wide working temperature range, and good trajectory performance. Two rows of charging assemblies are evenly distributed in a combustion chamber shell body, and after ignition of the engine, fuelgas amount of the catapulting engine is gradually increased with time. A two-path ignition tube is installed at the head part, redundancy design is conducted, reliable ignition energy is provided, and spherical propellant is ignited. The volution is used to fix the spray pipe at the tail part, and the process is mature, simple and convenient. The catapulting engine can be applied to of missile orcarrier rocket emission in a wide temperature range, the initial overload is low, and the stability and reliability of missile or carrier rocket emission are improved.

Description

technical field [0001] The invention belongs to the field of missile launch, and in particular relates to a catapult engine. Background technique [0002] The catapult engine can be used to launch a missile or a carrier rocket, which can increase the mobility of the missile or carrier rocket; on the other hand, after the ejection, the missile or carrier rocket is ignited at high altitude, which can reduce the negative effect of the tail flame on the ground equipment and personnel. influences. Catapult engines have the advantages of improving the maneuverability and safety of missiles or carrier rockets, and are widely used in missiles or carrier rockets. Existing catapult engines use columnar charges, which have a small increase in surface area and large overload, which has adverse effects on platform devices. , and even damage the platform equipment, resulting in launch failure. Contents of the invention [0003] The purpose of the present invention is to provide a cata...
