album - "Play it loud"! This video shows recent hot-fire tests of Pratt & Whitney Rocketdyne's Bantam demonstration engine for the "pusher" launch-abort system on Boeing's CST-100 commercial crew capsule.Video: Boeing
The rocket engine is designed to push the spacecraft clear of its booster in the event of a launch abort, but - if it is not needed - the propellant can be used elsewhere on the mission. such as re-boosting the space station's orbit after docking. The engine produced 52,000-54,000lb thrust during the tests, conducted in the California desert.
Boeing is working on design of the seven-seat CST-100 capsule under NASA's Commercial Crew Development program. The company is teamed with Bigelow Aerospace, which hopes to use the Atlas V-launched CST-100 for transport to and from its planned inflatable space complex.
