Propulsion method, propulsion device, and propulsion unit including a combustion step of liquid oxidant and hydrogen generated using a solid compound

摘要

One subject of the present invention is a propulsion method comprising: the injection, into at least one combustion chamber (1), of at least one liquid oxidizer (OX) and of hydrogen (H2); the combustion of said at least one liquid oxidizer (OX) and hydrogen (H2), in said at least one combustion chamber (1), for the generation of combustion gases; and expulsion of said combustion gases. Said process comprises, upstream of said injection: the generation of at least one portion of said hydrogen (H2), advantageously of all said hydrogen (H2), from at least one solid compound (5); said generation from said at least one solid compound (5) comprising a combustion reaction between said at least one solid compound (5) chosen from alkali metal borohydrides, alkaline-earth metal borohydrides, borazane, polyaminoboranes and mixtures thereof and an oxidizing charge (5). Another subject of the present invention is a propulsion device suitable for the implementation of said method.
