Liquid rocket engine test facility engineering challenges

Acta Astronautica, 2006
Abstract Liquid rocket engines for launch vehicles and space crafts as well as their subsystems need to be verified and qualified during hot-runs. A high test cadence combined with a flexible test team helps to reduce the cost for test verification during development/qualification as well as during acceptance testing for production.
