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.
