A High Performance Side Nozzle Solid Rocket Motor

Abstract

The invention discloses a high property solid propellant rocket engine with a laterally arranged nozzle. The high property solid propellant rocket engine with the laterally arranged nozzle comprises a charging combustion chamber, an ignition device and the nozzle, wherein a combustion chamber shell body of the charging combustion chamber is a hollow cylinder. The high property solid propellant rocket engine with the laterally arranged nozzle is characterized in that the nozzle is fixedly mounted at the opening of the outer side of the combustion chamber shell body in a sealed mode, the included angle between the axis of the nozzle and the axis of the cylinder of the combustion chamber shell body is 10-90 degrees. By arranging the nozzle laterally, the requirements for high thrust and high total impulse of the solid propellant rocket engine in a small using structural space are met; by designing a special-shaped nozzle shell body, the problem of sealed mounting of the laterally arranged nozzle is solved; by designing special-shaped nozzle throats, the problem that fuel gas in the charging combustion chamber flows along the wall caused by the nozzle arranged laterally is solved, and ablation and erosion on the position of the sealed mounting structure of the nozzle are substantially improved, the reliability of heat proof, load-carrying capability and connection sealing design on the position of the sealed mounting structure of the nozzle are improved, the integration of the engine work structure and the uniformity of internal ballistic property are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, in particular to a high-performance solid rocket motor with side nozzles. Background technique [0002] Most of the solid rocket motors adopt an axisymmetric rotary body structure, including a charge combustion chamber whose combustion chamber shell is a hollow cylinder, an ignition device and a nozzle. The nozzle is fixed and sealed at the rear opening of the combustion chamber casing, which cannot meet the solid The rocket engine needs to achieve high thrust and large total thrust in a small structural space. Contents of the invention [0003] The object of the present invention is to provide a kind of high-performance side-mounted nozzle solid rocket motor in view of the above-mentioned problem, comprise the charge combustion chamber that combustion chamber casing is hollow cylinder, ignition device and nozzle, it is characterized in that said nozzle The fixed seal is installed ...
