Problems solved by technology

[0021] On the contrary, the energy source that feeds the engine should be able to provide power in megawatts during the propulsion phase, which means that both for this energy source and for the components that power the electric motor, there are significant limitations in terms of weight and design size
[0022] Ultimately, the energy storage device and the engine as a whole are very heavy

[0108] According to a first embodiment, said internal combustion engine is a multi-cylinder engine of racing engine type.

[0109] According to an optional embodiment, the internal combustion engine 1 is an aviation axial flow turbocompressor engine.

[0110] Said engine 1 is fed by its own fuel reservoir 4 and oxidizer reservoir 5 , which are separate from the rocket fuel reservoir 3 of the "Ergol" rocket engine.

[0111] The combustion aid reservoir 5 is a pressurized gas reservoir connected to the air inlet of the engine through a pressure regulator 6 .

[0112] It comprises a cooling circuit, which is cooled by means of heat exchangers 12 arranged on one or more feed pipes 14 of cryogenic "Argau" rocket fuel, said cooling circuit operating in the form of a closed circuit.

[0113] The electric starter 7 allows starting the internal combustion engine.

[0114] figure 2 The rocket motor supply unit shown above comprises two pumps - each driven by a motor unit 1, 1', and ...

Abstract

The subject of the invention is a device for driving a pump of a rocket engine of a space vehicle that comprises an air-breathing internal combustion engine running on an oxidizer / fuel mixture of the air / hydrocarbon type, wherein the supply of oxidant and fuel is provided by tanks and a circuit that are separate from the propellant tanks of the rocket engine. The invention applies to a device for fueling a rocket engine that includes at least two pumps, each driven by the device of the invention, and means for controlling the internal combustion engines for driving the pumps, adapted for independently varying the operating parameters of these engines so as to independently adjust the rotation speeds of the pumps.

Description

technical field [0001] The present invention relates to an apparatus and method for driving a pump for a rocket motor by an internal combustion engine. Background technique [0002] The technical field that the present invention relates to is the technical field of rocket motor propulsion capable of strong propulsion as required by a space launching device. [0003] For this type of application, depending on the physical state of the "ergol" rocket fuel used, there are three types of technology, namely: solid propulsion, in which "ergol" rocket fuel is stored in the combustion chamber ; liquid propulsion, which can use one, two or even more "Elgo" rocket fuels, wherein the "Elgo" rocket fuel in the store should be delivered to the combustion chamber; and hybrid propulsion, said hybrid propulsion Liquid "Ergol" rocket fuel and "Ergol" solid rocket fuel are used, and liquid "Ergol" rocket fuel is to be delivered to a combustion chamber in which "Ergol" solid rocket fuel is st...
