SYSTEM FOR CONTROL OVER AIRCRAFT AIRFOIL VITALS Russian patent published in 2015 - IPC B64C13/12 

FIELD: aircraft engineering.

SUBSTANCE: claimed control system comprises the channels for remote control to be effected by the onboard digital computer and twin controls for both pilots: the pedals control the heading channel, bank and pitch channels are controlled by side-sticks, position transducers, moment transducers, motors, matching amplifiers, control air foil drive moment amplifiers, mechanical linkage channels, shaft clutches unit, differential mechanisms and elements of coupling with control airfoil drive system reduction gears. The drive system moment amplifiers comprise the motor with two-way reduction gearbox. Said mechanical linkage comprises the set of separate shaft lengths in tubes running in bearings and sections with flexible shaft coupled in a definite way. The differential mechanisms in the heading channel comprise the mechanical adder while those in the bank and pitch channels include the mechanical adder and differential multiplier. Reduction gears or multipliers comprise gearings with forward or reverse efficiency.

EFFECT: higher flight safety, simplified gearing, decreased weight.
