Thrust reverser actuation

A thrust reverser drive arrangement is described for use in driving a thrust reverser cowl (10) for movement relative to first and second guide tracks (12), the drive arrangement comprising a first actuator (16a) located, in use, close to the first guide track (12), and a second actuator (16b) locat...

Zusammenfassung:	A thrust reverser drive arrangement is described for use in driving a thrust reverser cowl (10) for movement relative to first and second guide tracks (12), the drive arrangement comprising a first actuator (16a) located, in use, close to the first guide track (12), and a second actuator (16b) located, in use, close to the second guide track (12), the actuators (16a, 16b) being arranged to be driven in synchronism and at the same speed by a drive motor (18) to drive the cowl (10) for movement, wherein at least one of the first and second actuators (16a, 16b) is provided with a load limiter (40) to limit the transmission of loads through that actuator (16a, 16b) in the event that that actuator (16a, 16b) is subject to a compressive loading greater than a predetermined level.
