초록

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...
