What are the duties of oxidizer turbine bypass valve in rock

What are the duties of oxidizer turbine bypass valve in rocket? How can we increase the efficiency of it?

Solution

Oxidizer turbine bypass valve is a normal open spring loaded gate type valve.

The duties of oxidizer turbine bypass valve are:

It is used to control the speed of the oxygen pump. During start the valve is in open position to suppress the speed of the oxygen pump.

It remains in closed position and acts as a calibration device to measure the turbopump performance.

It\'s efficiecay can be increased by controlling the size of the valve and it\'s opening.
