Rocket Motor Ground Tests

The rocket motor main components, the composite nitrous oxidizer tank and CTN (unitized motor case/throat/nozzle) have been in development at Scaled since mid 2001. Those components passed their qualification tests by late 2002. The other motor components (controller, valve, injector, aft bulkhead, head insulation, ignition system and fuel) are being developed and tested by two competing subcontractors. The two companies are eAc and SpaceDev .

Due to the competitive nature of the current rocket ground test program, test details cannot be divulged. The following are the dates of the full-scale motor firing events. This list does not include sub-scale or cold flow tests. All these tests have used full-scale, flight-article components, mounted on our mobile rocket motor test stand. The test stand uses the same tank, CTN and adjacent structure as SpaceShipOne.
