The latest test summary on RocketMotorTwo from Scaled Composites (via Clark Lindsay at Hobby Space). This is the first test firing since Nov. 29, 2011.
Fire: 09 Date: 13 March 12
Objectives: Ninth full scale flight design RM2 hot-fire. Continued evaluation of all systems and components: – Pressurization – Valve/Injector – Fuel formulation and geometry – Nozzle – Structure – Performance
Results: All objectives completed. Performed full 45 second hot fire as planned. Duration of burn chosen to allow examination of internal core geometry.
Sierra Nevada Corporation successfully test fired the RocketMotorTwo engine for the fifth time last week. The hot-firing was the first such test in over four months. Previous firings were done one:
