The Linear Aerospike Engine

Marshall's Legacy of Flight

Seeking to develop lighter, more powerful launch vehicles capable of versatile work in Earth orbit, NASA and Lockheed Martin Aeronautics of California experimented in the late 1990s with an engine without a nozzle. Developed to support the X-33 Advanced Technology Demonstrator Program here, the linear aerospike is shaped like an inverted bell turned inside out, "unwrapped" and laid flat. A series of small combustion chambers along the unwrapped bell shoot hot gases along its outer surface, producing thrust. The single-stage X-33 would have been powered by a pair of these engines. Though the X-33 program ended in 2000, the successful development of the linear aerospike engine is helping engineers refine new ideas for tomorrow's next-generation propulsion systems.
