Abstract
Official abstract text for this publication.
The present disclosure deals with the above problems by providing a TRAS architecture having a fully distributed motor configuration—i.e. having a single, smaller motor, for each actuator. The efficiency of the drive between the motor and the actuator output to which it is connected is maximised, but the efficiency of the mechanical connection between adjacent actuators themselves is minimised (preferably less than 50%) resulting in low torque transfer between actuators.
First claim
Opening claim text (preview).
1 . A thrust reverser actuation system comprising a plurality of actuators arranged to drive, in use, a flap or cowl; an inter-actuator shaft connecting each pair of adjacent actuators associated with the flap or cowl; a corresponding plurality of motors, a respective motor connected to and arranged to drive each of said actuators. 2 . A thrust reverser actuation system as claimed in claim 1 , comprising a first plurality of said actuators arranged to drive, in use, a first flap or cowl, and a second plurality of said actuators arranged to drive, in use, a second flap or cowl. 3 . A thrust reverser actuation system as claimed in claim 2 , wherein said first plurality of actuators are not connected to, and operate independently of, said second plurality of actuators. 4 . A thrust reverser actuation system as claimed in claim 2 , wherein said first plurality of actuators are connected to, and operate in dependence on, said second plurality of actuators. 5 . A thrust reverser actuation system as claimed in claim 1 , wherein the or each plurality of actuators comprises three actuators. 6 . A thrust reverser actuation system as claimed in claim 2 , wherein the or each plurality of actuators comprises three actuators. 7 . A thrust reverser actuation system as claimed in claim 3 , wherein the or each plurality of actuators comprises three actuators. 8 . A thrust reverser actuation system as claimed in claim 4 , wherein the or each plurality of actuators comprises three actuators.
