Title: Propulsion from the Pulse Detonation of Solid Propellant Pellet-Projectiles
Abstract: Conventional solid propulsion is one of the oldest methods of propulsion that make use of deflagration phe nomena rather than detonation to generate combustion gases. Proposed is a technology that makes use of detonation phenomena of solid propellants. This technology substantially departs from the conventional concepts and designs, and in doing so provides a system primarily developed for the purpose of providing a propulsion method that would have the advantages of both solid and liquid propulsion systems. The primary concept is that solid propellant pellets having a specific shape -profile is ejected in the fo rm of projectiles having a certain velocity, interacts with a medium for initiation and the detonation of the solid propellant pellets takes place in flight. The velocity, the shape profile of the propellant pellets and the detonation process determines fo rward direction of the combustion gases evolved. The proposed technology has a specific application in space vehicle propulsion, and also in satellites where a propulsion system is required to reach correct orbit and carrying out its useful mission. Furthe rmore, variants of the proposed concept can be employed as in the case of detonation driven ramjet s (dramjets) and detonation initiators for pulse detonation engines (PDEs) .
