Kinematic schemes drive of “more electric” aircraft were considered, were analyzed: potentials and limitation of actuating mechanisms with pivot-type, general requirements to functional elements of actuating mechanisms with pivot-type, ways their organization and the most perspective constructions such actuating mechanisms. Schemes of redundant drives with pivot-type and schemes drive of system, which controls the objects with lack of inflexibility were describe.


pivot-type actuating mechanisms; electro-mechanical actuators; aerodynamic control surface actuators; ball-rolling wave gear; “more electric” aircraft.
