In particular, the storage device 6 is adapted to contain a liquid propellant and a pressurized gas.
As an example, the pressurized gas may include a autogenous pressurized gas; in this case, the supercharging system may be a self-generating supercharging system.
As an example, the storage means 6 may comprise a tank. Of course, in other examples, the storage device 6 may be a storage bucket or tank, or the like.
As an example, the throttle device 2 is disposed on the supercharging ordinary pipe 11 for controlling the supercharging flow rate; specifically, the pressurization normal-open pipeline 11 can provide a pressurization flow of 70% -80%.
As an example, the first pressure regulator 3 is disposed on the pressurization regulating pipe 12, and the pressurization regulating pipe 12 may provide a pressurization flow of 0 to 40%.
As an example, the second pressure regulator 4 is disposed on a pressurizing redundancy line 13, and the pressurizing redundancy line 13 may provide a pressurizing flow rate of 0 to 40%.
As an example, both the first pressure regulator 3 and the second pressure regulator 4 may have a locking function.
As an example, the second pressure regulator 4 is provided in the pressure boosting redundancy line 13, and a single point failure mode in which the first pressure regulator 3 of the first pressure boosting regulation line 12 is stuck at an arbitrary opening degree can be eliminated.
As an example, the supercharging system further comprises:
a diffuser 5, the diffuser 5 is located in the storage device 6 and is located at the output end of the pressurizing pipe.
In particular, the diffuser 5 is used for pressurized gas energy dissipation.

a first main boost pipe 14, wherein one end of the first main boost pipe 14 is used as an input end of the boost pipe to input the boost gas, and the other end of the first main boost pipe is connected with the first end of the normal-pressure adding pipe 11, the first end of the boost adjusting pipe 12 and the first end of the redundant boost pipe 13;
and one end of the second main pressurizing pipeline 15 is connected with the second end of the normal-open adding pipeline 11, the second end of the pressurizing adjusting pipeline 12 and the second end of the pressurizing redundancy pipeline 13, and the other end of the second main pressurizing pipeline 15 is used as an output end of the pressurizing pipeline to extend into the storage device 6.

As an example, the supercharging system further comprises:
and one end of the pressure measuring tube 7 is communicated with the inside of the storage device 6, and the other end of the pressure measuring tube 7 is connected with the first pressure regulator 3 and the second pressure regulator 4.

As an example, the first pressure regulator 3 and the second pressure regulator 4 regulate the opening according to the pressure feedback of the storage device 6 (i.e. the test result of the pressure measuring tube 7), so as to achieve the pressure closed-loop control of the storage device 6, and the pressure control requirement range of the storage device 6 is greatly reduced, the impact of the step change of the flow rate of the pressurized gas on the combustion chamber of the engine is greatly reduced, the working stability of the engine is improved, and the working reliability and stability of the liquid rocket power system are ensured.
Specifically, the first pressure regulator 3 controls its opening according to the pressure feedback of the storage device 6, and when the pressure of the storage device 6 is higher than the highest value of the set range of the first pressure regulator 3, the first pressure regulator 3 is locked; when the pressure of the storage device 6 is lower than the highest value of the setting range of the first pressure regulator 3, the storage device 6 is opened, the pressure decreasing opening is increased, and the pressure increasing opening is decreased. The second pressure regulator 4 controls the opening degree according to the pressure of the storage device 6 fed back by the pressure measuring pipe 7, and when the pressure of the storage device 6 is higher than the highest value of the set range of the first pressure regulator 3, the second pressure regulator 4 is locked; when the pressure of the storage device 6 is lower than the highest value of the set range of the first pressure regulator 3, the second regulator 4 is opened, the pressure-decrease opening degree is increased, and the pressure-increase opening degree is decreased.
More specifically, as shown in fig. 2, the pressure ranges P3 to P1 may be adjusted for the first pressure regulator 3, the pressure of the storage device 6 is higher than P1, and the first pressure regulator 3 is locked; when the pressure of the storage device 6 is lower than P3, the first pressure regulator 3 remains fully open; in P3 to P1, the pressure-decrease opening degree increases, and the pressure-increase opening degree decreases. The second pressure regulator 3 regulates the pressure ranges P2 to P1. The pressure of the storage device 6 is higher than P1, and the second pressure regulator 3 is locked; when the storage device 6 is below P2, the second pressure regulator 3 remains fully open; in P2 to P3, the pressure-decrease opening degree increases, and the pressure-increase opening degree decreases.
In summary, in the pressurization system of the present utility model, by providing multiple pressurization (i.e., the additional normal-pressure pipeline 11, the pressurization adjusting pipeline 12 and the pressurization redundant pipeline 13), it is possible to avoid the pressure abnormality of the tank due to the failure of the single pressurization pipeline until the rocket flight fails, thereby improving the reliability and stability of the system. The first pressure regulator 3 and the second pressure regulator 4 regulate the opening of the valve through the pressure feedback of the storage device 6, so that the pressure control of the storage device 6 is achieved, the regulation process is timely and continuous, the impact of the step change of the flow rate of the pressurized gas on the combustion chamber of the engine is greatly reduced, and the working stability of the engine is improved.
