ABSTRACT:
A projectile having an efficient integrated propulsion system such that the projectile can guide itself to a target. The projectile comprises a body in which eight supersonic nozzles are positioned. The nozzles are arranged such that each nozzle can provide a reaction force having nonzero components along first and second axes that are fixed with respect to the body and orthogonal to one another. The nozzles are arranged in first and second groups of four nozzles each, the first and second groups being spaced from one another along a third axis orthogonal to the first and second axes. The third axis is generally parallel to the course of the projectile towards the target. The nozzles in each group are arranged such that for each direction along each of the first and second axes, two nozzles of the group can produce a reaction force having a nonzero component along that direction. Each nozzle preferably comprises a Prandtl-Meyer expansion nozzle that is lineraly elongated along the third axis.
