This invention relates to the control and direction of flight of an aircraft, and is particularly relates to high speed aircraft of the rocket type which are propelled by discharge of gases from a combustion chamber. It has been heretofore proposed to control the flight of such aircraft by fixed external vanes, or by vanes which are selectively moved into the slip stream of air surrounding the aircraft or into the rocket blast. Such vanes, if external, have serious air resistance which produces drag and reduces their steering effectiveness. If internal and movable into the rocket blast, the efficiency of the blast is decreased. Moreover, if the speed of the craft varies widely, air vanes of fixed size are found unsatisfactory. If the vanes are large enough to provide satisfactory steering at low velocities, they are too large for use at high velocities; they are too small to be effective at low velocities. It is the general object of my invention to provide improved means for steering aircraft, which steering means will be effective and satisfactory at low, moderate or high speeds, will be independent of the rocket blast in aircraft of the rocket type and equally effective whether the rocket blast is in operation or otherwise, and which will permit full streamlining of the aircraft. More specifically, my invention in its preferred form relates to means for effecting changes in the longitudinal alignment of different longitudinally disposed elements of an aircraft, by which changes in alignment the direction of flight may be controlled.
