Preburner Test

We successfully tested the preburner for Pyralis today! The pre-burner acts like a pilot light during the engine start up sequence – the flames from the preburner will heat the combustion chamber, and will cause the main propellants to burn when they are flowed into the chamber. The pre-burner runs on propane and compressed air, and is initiated by a spark. In this test, the combustion chamber is not present, so that we can observer the preburner flame jetting out of the injector.
