Abstract
The disclosure pertains to a projectile guided by successive lateral gas jets by way of pairs of impellers. The impellers of one pair are fired so as to exert opposite moments of rotation. According to the disclosure, the impellers are brought together in two groups. Of the impellers of one pair, one is in one group and the other is in the other group. The impellers of each of the groups are separated by diode bulkheads that withstand the pressure of the impeller that is located on one side of the bulkhead and is fired first, but does not withstand the firing of the impeller that is located on the other side of the bulkhead and is fired second. The impellers of one group lead into one and the same nozzle. Thus, the making of the guidance impellers is simplified at the same time as the control of the guidance is improved.
