ABSTRACT:
A rotary hinge actuator, for instance for rotating a wing flap relative to a wing in an aircraft, has a sun gear, several spindle gears around the sun gear and several annular gear sleeves around the sun gear and spindle gears. Each spindle gear has sections with external helical gear teeth which are slanted in the same direction and which respectively mesh with internal helical gear teeth on the annular gear sleeves. At least one of the sleeves is connected to the wing and at least another to the wing flap. Upon rotating the spindle gears the wing flap is rotated relative to the wing.
