A hybrid rocket motor is formed from a single piece of material, such as, for example, by extrusion or injection molding. The rocket motor includes various components, such as casing, structure, oxidizer tank, combustion chamber, fuel, port and nozzle that are all formed from a single piece of material. The material can be, for example, a material that can be used as solid rocket fuel.

Single-piece hybrid rocket motor

Disclosed is a propulsion system having a structural configuration that provides easy and convenient access to the interior regions of a liquid fuel tank and a hybrid rocket motor case. The system operates with a high oxidizer-to-fuel ratio and a high bulk density propellant combination that has a near uniform specific impulse over a large oxidizer-to-fuel ratio range. The system has an increased propellant mass fraction and reduced propellant residuals. This improves the performance of the hybrid propulsion system.
