Abstract
An aircraft flight surface actuator has at least one eccentric cam mechanism, the eccentric cam mechanism imparting movement onto the flight surface.
Claims13
An aircraft flight surface actuator comprising:
- at least one eccentric cam mechanism, the eccentric cam mechanism having an eccentric cam co-operating with a lever assembly, the lever assembly being arranged to be coupled to a flight surface, whereby rotation of the eccentric cam imparts movement of the flight surface;
- and
- a drive mechanism arranged to transmit a rotational driving force to the or each eccentric cam mechanism, the drive mechanism includes a gearbox arranged to receive a rotational driving force having a first speed and to convert the rotational driving force to a second speed prior to transmitting the driving force to the or each eccentric cam mechanism.
An aircraft flight surface actuator according to claim 9, wherein the lever assembly comprises a first lever element in engagement with the eccentric cam and a second lever element pivotally connected to the first element, the second element being arranged to be coupled to the flight surface.
An aircraft flight surface actuator system comprising a plurality of aircraft flight surface actuators and a power drive unit arranged to impart a rotational driving force to each of the plurality of aircraft flight surface actuators, wherein each aircraft flight surface actuator comprises at least one eccentric cam mechanism, the eccentric cam mechanism having an eccentric cam co-operating with a lever assembly, the lever assembly being arranged to be coupled to a flight surface, whereby rotation of the eccentric cam imparts movement of the flight surface.
