A thrust reverser drive arrangement is described for use in driving a thrust reverser cowl for movement relative to first and second guide tracks, the drive arrangement comprising a first actuator located, in use, close to the first guide track, and a second actuator located, in use, close to the second guide track, the actuators being arranged to be driven in synchronism and at the same speed by a drive motor to drive the cowl for movement, wherein at least one of the first and second actuators is provided with a load limiter to limit the transmission of loads through that actuator in the event that that actuator is subject to a compressive loading greater than a predetermined level.

Thrust reverser actuation

A thrust reverser drive arrangement for driving a thrust reverser cowl for movement relative to first and second guide tracks is described which comprises a first actuator located, in use, close to the first guide track, a second actuator located, in use, close to the second guide track, and a third actuator, the actuators being arranged to be driven in synchronism and at the same speed by a drive motor to drive the cowl for movement, the third actuator being of smaller size and/or weight than the first and second actuators, and wherein the third actuator is provided with a load limiter to limit the transmission of loads through the third actuator in the event that the third actuator is subject to a compressive loading greater than a predetermined level. The invention further relates to a load limiter device suitable for use in such an arrangement.

An actuator comprises a first actuator arrangement operable to allow relative axial movement to occur between a first component and a second component, a second actuator arrangement operable to allow relative axial movement to occur between a third component and a fourth component, brake means operable to prevent extension of the first and/or second actuator arrangement, and damping means operable to control the rate of extension of at least one of the first and second actuator arrangements.
