Definitions
- the present invention relates to a propulsion unit for a rocket comprising a propellant tank and a method of pressurizing said tank.
- the engine is usually an engine in which the exhaust gases generated in a combustion chamber are discharged via a nozzle so as to develop a thrust.
- Rocket engines are known in the prior art supplied with liquid propellant (s).
- the propellants are contained in tanks and are conveyed by means of supply conduits to the combustion chamber of the engine in which they are mixed.
- This mixture of propellants produces combustion in which the exhaust gases evacuated by the nozzle at the outlet of the combustion chamber cause the rocket to take off.
- gas stored under high pressure is generally used in auxiliary gas reservoirs which are injected into the reservoir to ensure the pressurization of the propellant reservoir (s).
- these gases are neutral so as to avoid any reaction with the propellant contained in the tank to be pressurized.
- Tank pressurization devices are also known using the exhaust gases from the combustion chamber to vaporize propellant in a heater. The propellant vaporized in the heater is then injected into the tank in order to ensure its pressurization. The exhaust gases are generally discharged outside the powertrain assembly.
- Devices are also known using hot gases from an external gas generator then cooled by water to ensure the pressurization of the tanks.
- a drawback of the solutions of the prior art lies in the need to embed auxiliary reservoirs to contain the pressurization gases of the reservoir and / or of the coolant fluid reservoirs.
- the architecture of the rocket stages is made more complex and heavier, leading to an increase in manufacturing costs and a loss in performance of these launchers.
- the object of the invention is in particular to alleviate at least one of these drawbacks and relates, according to a first aspect, to a propulsion unit for a rocket comprising a tank designed to contain a propellant, an engine comprising a combustion chamber configured to make undergo combustion with propellant generating exhaust gases, a supply circuit arranged between the propellant tank and the combustion chamber configured to supply the combustion chamber with propellant and an exhaust gas circuit arranged between the combustion chamber and the propellant tank configured to convey at least part of the exhaust gases from the combustion chamber to the propellant tank in order to ensure its pressurization.
- the exhaust gas circuit according to the invention at least part of the exhaust gas generated in the combustion chamber is directly routed into the tank for its pressurization. Thus, the exhaust gases are recycled into the tank. Auxiliary gas tanks are no longer required to store pressurization gas.
- the structure of the propulsion unit is lighter and less expensive.
- the architecture of the propulsion unit is simplified.
- the propulsion unit of the invention comprises one or more of the following optional characteristics considered alone or in all possible combinations.
- the exhaust gas circuit comprises at least one channel opening out to the outside of the tank.
- the exhaust gas circuit comprises an expansion device, adjacent to the reservoir and configured to regulate the flow rate of the exhaust gas entering the reservoir.
- the flow rate regulation makes it possible to maintain a constant pressure inside the propellant tank, equal to a predetermined value.
- the expansion device may for example be a pressurization plate or a holder.
- the expansion device is a pressurization plate.
- the pressurization plate comprises at least one pressure regulating valve.
- the propulsion unit comprises means for measuring the pressure of the reservoir. This ensures that the pressure inside the tank is constant and equal to a predetermined value.

- structures with single and / or double bonds between nitrogen atoms which are of lower energies are favored.
- the main advantage of using a metastable poly-nitrogenous mono-propellant is that its combustion mainly produces nitrogen and thus eliminates the risk of a chemical reaction when the exhaust gases generated enter the tank .
- the invention relates to a method for pressurizing a propellant tank of a propulsion unit as described above, the method comprising steps of:
- the pressurization method according to the invention comprises one or more of the following characteristics, taken separately or in combination:
- the propellant provided is a mono-propellant, preferably the propellant provided is a metastable poly-nitrogenous mono-propellant.
- the pressurization process comprises a step of cooling the exhaust gases in a heat exchanger.
- the pressurization method comprises a step of regulating the pressure inside the reservoir, said step comprising: determining a pressure value to be maintained inside the reservoir prior to the step of the propellant supply, a measurement of the pressure inside the tank during the delivery of the propellant into the combustion chamber, a modification of the position of one or more pressure control valves, the valve (s) ( s) being closed when the pressure measured inside the tank is less than the pressure value to be maintained, at least one valve being open when the pressure measured inside the tank is greater than the pressure value to be maintained, so as to divert at least part of the exhaust gases outside the tank.
