| titleOfInvention | Circulation precooling system for turbo pump of rocket engine and rocket |
| abstract | The invention provides a circulating pre-cooling system for a turbo pump of a rocket engine. High pressure gas is introduced into the turbine through a starter to blow the turbine to rotate, thereby driving the first pump and the second pump to rotate, so that the first pump and the fuel storage pump are rotated. A pressure difference is generated inside the tank and the associated delivery channel, and a pressure difference is generated within the second pump, the oxidant storage tank and the associated delivery channel. Under the action of the pressure difference, the low-temperature fuel enters the first pump from the fuel storage tank, and returns to the fuel storage tank after pre-cooling; Fuel tank. The invention uses the original device inside the rocket to pre-cool the turbo pump, and no other equipment such as a pre-cooling circulating pump or a motor is additionally provided, so that the turbo pump is fully pre-cooled, and the complexity and manufacturing cost of the system are reduced, and it is beneficial to The weight of the rocket is reduced, thereby improving the overall performance of the rocket. |
