초록

A rotary actuator (16) has an inner body (32) forming a rotor and at least one outer body (34) forming a stator. The inner body (32) and outer body (34) carry blades (40,44) arranged in an alternating manner and defining between them two series of variable volume chambers. The cross-section of the chambers and the height of the triangular blades (40,44) decreases from one end to the other, as a result of a substantially frustum-shape of the inner body (32). Such an actuator (16) can be used for controlling an aircraft rudder or control surface and it is ...
