NEW HIGH ENERGETIC COMPOSITE PROPELLANTS FOR SPACE APPLICATIONS: REFRIGERATED SOLID PROPELLANT
2009
Cryogenic solid propellants (CSP) are a new kind of chemical propellants that use frozen products to ensure the mechanical resistance of the grain. The objective is to combine the high performances of liquid propulsion and the simplicity of solid propulsion. The CSP concept has few disadvantages. Storability is limited by the needof permanentcooling between motor loading and ¦ring. It needs insulations that increase the dry mass. It is possible to limit signi¦cantly these drawbacks by using a cooling temperature near the ambient one. It will permit not to change the motor materials and to minimize the supplementary dry
