The invention relates to a wing-stabilized projectile having a transverse thrust steering arrangement. The transverse thrust steering arrangement is constructed in such a way that the release of thrust impulses out of control nozzles is achieved, independently from each other and oscillation free, whereby an excess pressure in the drive system of the transverse thrust steering mechanism is avoided. This is achieved in that in a control block there is provided at least one movable sealing member which is connected with a signal converter as well as with a control conduit having a centrally arranged sealing member, whereby by unloading the end surface of the sealing member it is opened and permits the outstreaming of generator gases which form a radial thrust impulse F via a control nozzle effecting a flight correction. The pressure loading of the end surface of the sealing member produces a closing process of the closing member at the end of the flight correction whereby the prior closed control member which is centrally mounted in the control block is pressure-unloaded via a throttle, so that the generator gas can be drawn off via of feed conduit and a draw-off conduit in a momentum-free manner.
An improved autonomous steering system for a fin-stabilized projectile having a gas generator which emits gases for steering the projectile by means of gas thrusts transversely with respect to the longitudinal axis of the projectile, and including a steering block having at least a pair of parallel bores in each of which a sealing member is slidably movably mounted, a first one of said sealing members being operatively connected to an electrically actuated signal converter means, and a nozzle for emitting a transverse thrust with respect to the longitudinal axis of the projectile being in fluid communication with the bore in which said first one of said sealing member is slidably mounted, the improvement comprising said bore with which said nozzle is in fluid communication and in which said first one sealing member is slidably mounted is disposed parallel to the longitudinal axis of said projectile in said steering block and is connected to said signal converter means via a separate signal carrier, whereas said bore in which the other second sealing member is slidably movably mounted is in fluid communication with said gas generator via a first gas conduit and includes a gas draw-off passage and is coaxially disposed with respect to the longitudinal axis of the projectile.
