PCT No. PCT/AU81/00160 Sec. 371 Date Jul. 2, 1982 Sec. 102(e) Date Jul. 2, 1982 PCT Filed Nov. 11, 1981 PCT Pub. No. WO82/01745 PCT Pub. Date May 27, 1982.A self-propelled rocket vehicle (1) in which ramp tabs (R1, R2, R3) are provided to control pitch and roll and vane tabs (V1, V2) provided to control spin. The ramp tabs comprise an array of generally symmetrically spaced tabs (R1, R2, R3) mounted on the vehicle and displaceable into the nozzle efflux (E) to control rotation of the vehicle about the roll axis (RA) and pitch axis (PA). The vane tabs (V1, V2) are placed symmetrically about the ramp tabs and are angled such that, when displaced into the nozzle efflux (E), spin in either direction about the vehicle longitudinal axis (SA) results. Overall control is achieved by an auto-pilot controlling actuators driving the ramp tabs and vane tabs to produce the desired thrust vectoring and spin control with the height of the vehicle being controlled by a height controller connected through a limiter to all ramp tabs to minimize loss of attitude control.
