An improved jet thruster system for use in a helicopter without a tail rotor. A non-rotating outer thruster assembly is attached to the rear of the tail boom which, within it, has a source of low pressure air. The outer thruster assembly has a window on each side. Nested within the outer thruster assembly is an inner thruster assembly with a single window which rotates within the outer thruster assembly in response to commands from the helicopter control system. As the single window in the inner assembly is rotated around to where it overlaps with one or...


[ What is claimed is:] [1.] An improved jet thruster system attached to the end of a hollow tail boom on a helicopter, through which boom passes air for expulsion by the jet thruster system, the system comprising:a non-rotating, substantially cylindrically shaped, outer thruster assembly attached to the end of the boom and having laterally opposing outer thruster windows providing respective air passages outwardly extending therethrough;a substantially cylindrically-shaped inner thruster assembly nested within the outer thruster assembly, capable of rota...
