The trajectory of a projectile is variable by means of a thrust generated by gas issuing from a nozzle, the nozzle normally rotating at high speed about the axis of the projectile but assuming a desired angular orientation for a predetermined period of time in order to impart a lateral thrust to the projectile thereby changing its trajectory.
Guidance apparatus adapted to be mounted on a projectile for guiding the projectile during flight, the apparatus comprising: (a) source of pressurised gas; (b) a nozzle rotatable about an axis and arranged to discharge gas produced, in use, from said source in a direction that is substantially perpendicular to said axis; (c) first thrust vector control means adapted selectively to set up a disturbance, for example shock-waves, within the gas being discharged from the nozzle so as to produce a resultant thrust that causes the nozzle to rotate continuously...
