ABSTRACT:
The invention relates to a thrust nozzle system, especially for steering a rojectile, having a nozzle arrangement (3) which is fed by a propellant source, for example a gas source. The nozzle system is arranged in a housing having at least one exhaust port (11) provided in the housing, and has a control (14) for steering a thrust jet (18) of the nozzle arrangement through the exhaust port. The invention provides a thrust nozzle system of simple construction which is especially suitable for a high miniaturization, and which permits a flexible thrust impulse forming. For this purpose the thrust nozzle system (2) has a rotating nozzle or a swinging nozzle body (3) which is rotatable relative to the housing about an axis, driven by the propellant, for example by the gas stream (P) from the gas source. The drive of the rotating nozzle body is preferably achieved by an acentric thrust nozzle (10) itself. Due to the low mass and hence low inertia of the nozzle body (3), it may be caused to rotate fast. A braking arrangement (14) is provided for the rotating nozzle body for steering the thrust jet (18) in a defined direction. Such a thrust nozzle system may serve for many uses, for example in conjunction with a secondary injection system or a hot gas motor.
