Abstract
A projectile, which spins in flight about a spin axis, including a source of pressure fluid, efflux outlet means in flow connection with said source, the efflux outlet means comprising at least two nozzle members symmetrically spaced about the spin axis, each nozzle member being pivotally mounted on the projectile, and means responsive to the prevailing spin rate effective to pivot the nozzle members such that the effective radius centred upon the spin axis at which the thrust generated by the efflux from the nozzle members is operative can be varied whereby the torque applied to the projectile about the spin axis can be varied without the necessity of measuring the spin rate or effecting throttling of the efflux.
