Hydrogen-Oxygen Motor : 4 Systems Make Up

A hydrogen-oxygen motor is an motor that uses liquid hydrogen and liquid oxygen as fuel. Hydrogen-oxygen motor is one of the trends in the development of rocket motor technology in the world. Mastering the technology of hydrogen-oxygen motor is one of the symbols of a country becoming a space power. The development of large thrust hydrogen-oxygen motor is the development trend of liquid rocket motor technology at home and abroad. What are the components of the oxyhydrogen engine?    Eaton Char-lynn Motor     Description:

 

1, blowing and pre-cooling system

Hydrogen/oxygen propellants have low boiling point and density, which gives the hydrogen/oxygen motor design some design features that are different from conventional propellant engines. Among them, the hydrogen/oxygen motor must be blown out before the start-up is one of its remarkable features. The purpose of the pre-cooling pre-cooling procedure before the start of the hydrogen/oxygen motor is to ensure that there is no air, moisture and impurities in the delivery conduit and the pump before the start-up and that the propellant is in a liquid state in order to ensure that the turbo pump can start normally. Once the motor is started normally, its operation is the same as that of a typical propellant engine.

 

2, starting system

The starting system is a power system in which the motor accelerates from a non-working state to a main working state. HM7 and HM60 use gunpowder starter; J-2 uses hydrogen starter bottle; RL-10 starts up as the main system itself; and the space shuttle main motor starts more advanced, it is controlled by computer program.

 

3. Propellant delivery system

The propellant delivery system includes a combustion chamber propellant supply system and a gas generator supply system.

Except for the space shuttle main motor using a high pressure afterburning system, several other engines are conventional turbo pump supply systems, and the main system is basically the same. They all include: liquid hydrogen, liquid oxygen turbine pumps, propellant main valves, ignition devices, thrust chambers and delivery conduits.

 

4. Propellant regulation and utilization system

The motor propellant conditioning and utilization system refers to a control system that controls motor thrust and mixing ratio accuracy and ensures that the tank propellant is simultaneously depleted.
