The invention relates to improvements with regards to the control of VTOL aircraft that use two propellers or fans as the primary lifting devices in hover. More particularly, the invention is a means for effecting control of the aircraft using just the two propellers alone, and comprises the in-flight tilting of them--which are of the conventional, non-articulated type (though they may have collective blade-pitch)--directly and equally towards or away from one another (and therefore about parallel axes) as necessary for the generation of propeller torque...
1. A system for controlling the attitude of an aircraft about an axis in flight, said aircraft comprising two spinning lift or propulsion devices which are counter-rotating, and said system comprising means for tilting the spin axes of said devices such that components of their tilting can essentially be equally and simultaneously towards or away from one another and by an amount and rate dictated by the operator, and the tilting of said devices using said components, thereby generating unbalanced torque-induced and gyroscopic moments which act on the ai...
