WebThe X-33's direction of flight will be controlled by varying the thrust side to side and engine to engine, rather than by adjusting the direction of a bell nozzle. The lack of systems for thrust vectoring -- such as gimbals, hydraulics and flex lines -- also will make the aerospike easier to maintain than conventional engines and help keep the X-33's weight down.
