Scaled Composites news: Engine performance at altitude

Objectives:
Engine performance at altitude. New pilot masks and ECS airflow routing. Regulated bleed air control of the aft cabin temperature (to test the capability to heat SpaceShipOne’s nitrous oxidizer. Appraisal of new traffic alert system.
Results:
Engines showed much improved performance up to 50,000 feet. ECS changes confirmed to assure clear windows for landing. Successful bleed air heating test: good control and sufficient energy for SS1 propellant heating. Read More
