ABSTRACT:
The invention relates to an apparatus for controlling a projectile (1) having a nozzle arrangement (2) rotatably arranged in the projectile housing. The nozzle arrangement comprises a rotary nozzle body (3) with a thrust nozzle (4) which nozzle body can be brought into any desired angular position by means of a positioning drive. The rotary nozzle body (3) is coupled to a gas generator (7) for a propellant gas supply. For optimum utilization of the propellant gas of the gas generator, in all angular positions of the rotary nozzle body (3), the axis of rotation (a) of the rotary nozzle body (3) is arranged to be non-parallel to the longitudinal axis (A) of the projectile. In addition, guiding means (4, 11, 12, 13, 14) are provided for the gas jet which steer the latter, depending on the angular position of the rotary nozzle body (3), substantially crosswise to the longitudinal axis (A) of the projectile for steering said projectile or into a direction substantially parallel to the longitudinal axis (A) of the projectile to provide an additional propulsion to the projectile. Preferably, the rotary nozzle body (3) comprises an offset thrust nozzle (4) and is incident with its axis of rotation (a) to the longitudinal axis (A) of the projectile in an acute angle (beta).
