Title System Design of Landing Buffer Solid Rocket Motor for the Air-drop Platform
Abstract
In the 1950's, the solid rocket broke through a lot in the technical field , and the solid rocket motor was widely used in ballistic missiles and launch vehicles. The appearance of the Landing Buffer solid rocket motor has opened a new direction of development with a lot of potential applications in the aerospace and military fields. This paper mainly introduces the principle and the key technology of the system of the landing buffer solid rocket motor for the air-drop platform and expounds the development and its current situation.Finish the design of the system of the landing buffer solid rocket motor for the air-drop platform and the rocket engine general structure, propellant structure design, the combustion chamber design, nozzle design, the ignition system design and interior ballistic calculation. At the same time, complete the computational analysis of the designed system. The research results of this paper hope to build a solid foundation for the development of high-performance solid rocket motor and the technology of high weight air-drop platform system.
Keywords Landing Buffer solid rocket motor The overall structure Propellant structure Air-drop system
