Propulsion assembly a solid propellant, which does not have a tuyere, and advantages of a vehicle acceleration

摘要

P the present invention relates to the field of the propulsion of the vehicles by means of a propellant charge carried out in the solid propellant. / p & & p & preferably, according to the invention, the envelope willing around the propellant charge, constituted by elements separate propellant homogenous, is substantially cylindrical and does not therefore possesses of the tuyere, this loading being initially set to fire under conditions allowing a stable combustion of the propellant, and this charging continuing to burn for a lower has a second time under conditions corresponding theoretically is an unstable combustion of the propellant. / p & & p & the invention makes it possible to carry out of the propulsion assemblies of acceleration of the grinding rocket, and is more particularly for the acceleration of the vehicles tires from a launcher tube. / p
