Watch as Aerojet Rocketdyne fires up the #Boeing #Starliner Launch Abort Engine in the Mojave Desert. This video is from a series of tests done to confirm the new valves are able to modulate propellant flow and control peak Launch Abort Engine thrust in the event of a launch abort. The CST-100 Starliner has four total Launch Abort Engines, each with 40,000 pounds of thrust each and up to 5.5 second firing duration capability. The Launch Abort Engines have an innovative, new propellant valve for the Starliner service module propulsion system. #engine #NASA #commercialcrew #space #aerojetrocketdyne
