Abstract
An anaerobic propulsion device of hybrid type. The propulsion device includes a combustion chamber into which an oxidant is injected thereto comes into contact with a fuel. The chamber includes an orifice, notably a nozzle, to inject the combustion gases. The fuel takes the form of solids divided into granules, typically grains, powder or beads. The propulsion device further includes a segregation device arranged between a reservoir for granules of solid fuel, and the combustion chamber. The segregation device is configured to prevent granules of fuel in solid form from passing between the reservoir and the combustion chamber. The segregation device includes orifices to allow the passage of the fuel, once the fuel has become pasty, liquid or vaporized.
Claims24
An anaerobic propulsion device of a hybrid type, the device comprising a segregation device arranged between a reservoir of granules of fuel in a solid form and a combustion chamber;
- the segregation device is configured to prevent the granules of the fuel in the solid form from passing between the reservoir and the combustion chamber, the segregation device comprises orifices to allow a passage of the fuel that has become pasty, liquid or vaporized;
- the reservoir comprises a pressure device to apply pressure to the granules to push the granules toward the segregation device, the pressure device comprises a deformable membrane arranged at a surface of the reservoir of the granules, and wherein the segregation device further comprises a structure made of porous material with open pores, wettable by the fuel that is locally liquefied under an action of heat.
