This burner is capable of operating on a variety of gaseous fuels and oxidizers, including hydrogen-air mixtures, with a low pressure drop. The burner provides a rapidly and uniformly mixed fuel-oxidizer mixture that is suitable for use in a fully premixed combustion regime that has the benefits of low pollutant emissions and freedom from harmful flashback effects, combustion instabilities, and thermal meltdown problems.

Non-Pyrotechnic, Zero-Leak, Normally Closed Valves

Until now, the predominant normally closed valve assembly available for the aerospace industry was the pyrovalve, which has an unacceptable failure rate. To replace the pyrovalve, NASA developed the Nitinol-Actuated Normally Closed Valve Assembly, a zero-leak valve designed for liquid propellant service on in-space propulsion systems.
