These propulsion systems include rocket motors, turbojet and turbofan air breathing engines and ramjets.
Propulsion systems are the key to developing reliable future flight vehicles.
The most critical pacing element for aircraft, missiles and spacecraft is the flight vehicle's propulsion system. Testing of rocket propulsion systems provides information such as the burning characteristics of propellants, the precise amount of thrust delivered, durability of the engine and compatibility of the components and associated controls. Simulated flight tests of rocket propelled missiles or space systems can provide information which can reduce the number of costly launches and test flights and reduce the time required in development of a system. Flight failures cost millions of dollars and cause major schedule delays because typically they come very late in the development cycle. Ground tests of air breathing engines provide information such as performance, operability and reliability and can help cut development time and the number of flight tests required for manned aircraft or unmanned weapon systems such as cruise missiles.
