RHPS regulators and valves used in Rocket Technology
The test facility (TF3) can provide high mass flow rates of hydrogen and oxygen in very wide pressure ranges. The hydrogen storage is 240 nm³, oxygen storage is 240 nm³. Supply pressures range from 6 MPa to 24 MPa, and maximum mass flow rates are: for hydrogen 817 nm³/h (0,02 kg/s) and for oxygen 306 nm³/h (0,12 kg/s).
The facility can be used for testing small rocket motors, igniters (amongst others acoustic igniters), combustors and other devices that require hydrogen (or oxygen) such as for developments in hydrogen technology.
All test facilities have a versatile automatic control system, and data acquisition system that can record events at high frequencies. Standard measurements are measurements of pressure, temperature, and force. Additional measurements (e.g. spectroscopic measurements) are possible. Normal video recording of test runs is standard, high speed cameras are available for special test runs.
The research group has several test facilities all suited for work with hydrogen. There is also a large indoor test stand for testing (large) rocket motors, ramjets, ducted rockets, combustion research or base pressure measurements on scaled-down rockets, launchers or boosters.
Hydrogen, oxygen, nitrogen, methane and dry air can be supplied in large volumes. Air, for example, up to 5 kg/s. RHPS built and supplied the complete TF3 gas supply system and supplied many a regulator for the large indoor test stand, including 300 bar 3 inch domeloaded regulators.
