1. A method for gasifying and pressurizing liquid oxidant and liquid fuel, comprising the following steps:
a) driving liquid oxidant and liquid fuel (“propellants”) into the center of a rotating disc through inlet channels, keeping them separate;
b) driving the higher density liquid propellant through compressions ducts from its proximal end of the axis of rotation to a combustion chamber located at the distal end of the axis of rotation, rotating together with the compression ducts;
c) driving the lower density liquid propellant through compressions ducts from its proximal end of the axis of rotation to two different combustion chambers, located at the distal end of the axis of rotation, one called high-pressure combustion chamber, that is further away from the axis of rotation than the combustion chamber for the higher density propellant, and further away from the other combustion chamber, called low-pressure combustion chamber, all chambers rotating together with the compression ducts;
d) gasifying the lower density liquid propellant in the high-pressure combustion chamber and also in the low-pressure combustion chamber, by mixing it with liquid or gaseous higher density propellant;
e) gasifying the higher density liquid propellant in its combustion chambers by mixing it with the lower density propellant gases coming from the high-pressure combustion chamber for the lower density propellant;
f) driving the combustion gases rich in the higher density propellant, from the combustion chamber for the higher density propellant, into expansion ducts, which move together with the combustion chamber, from their distal end of the axis of rotation, to their proximal end of the axis of rotation;
g) driving the combustion gases rich in the lower density propellant, from the low-pressure combustion chamber for the lower density propellant, into expansion ducts, which move together with the combustion chambers, from their distal end of the axis of rotation, to their proximal end of the axis of rotation;
h) driving the gaseous propellants from the proximal end of the axis of rotation of the expansion ducts into the outlet ducts;
i) driving liquid propellants, on entering the disc, through bladed inlet channels which induce their entry into the disc, and increase their pressure;
j) driving gaseous propellants, on leaving the disc, through bladed outlet channels which slow down the rotation of the gas.
