VTOL AIRCRAFT CONTROL Russian patent published in 2014 - IPC B64C29/00 

FIELD: transport.

SUBSTANCE: invention relates to rotorcraft, namely, to VTOL aircraft. Method of control over VTOL aircraft with disc-shape or toroidal fuselage with rotors, their fulcrums aligned with fuselage axis, located inside the duct formed by fuselage or above it, comprises fitting toroidal sealed vessel in said fuselage to be filled with fluid and using fluid redistribution means. Redistribution of fluid in toroidal sealed vessel ensures variation and/or location of aircraft centre of gravity relative to engine thrust application point. Note here that the latter is located above aircraft centre of gravity. Aircraft displacement in space is ensured by shifting its centre of gravity in direction aligned with required flight direction and by increasing or decreasing engine thrust.

EFFECT: simplified design, higher reliability.
