JET ENGINE ACTUATION SYSTEM

摘要

A jet engine actuation system includes a first ring gearbox, a second ring gearbox and an actuator. The first ring gearbox includes a first ring driveshaft coupled to a first portion of a synchronization ring included in a jet engine. The second ring gear box includes a second ring drive shaft coupled to a second portion of the synchronization ring. The actuator has a first actuator gearbox configured to generate a first rotational output and a second actuator gearbox configured to generate a second rotational output. A first drive shaft transfers the first rotational output to the first ring gearbox and a second drive shaft transfers the second rotational output to the second ring gearbox. The actuator simultaneously controls the first and second actuator gearboxes such that the first and second rotational outputs are simultaneously transferred to the first and second ring gearboxes to rotate the synchronization ring.

1. A jet engine system, comprising:
at least one engine including:
a synchronization ring configured to circumferentially rotate;an inner housing that supports the synchronization ring; an actuation system including:
first and second ring gearboxes coupled to the inner housing and configured to rotate the synchronization ring;an actuator having a first gearbox configured to generate a first rotational output and a second actuator gearbox configured to generate a second rotational output;a first drive shaft having a first shaft end rotatably coupled to the first actuator gearbox and a second shaft end rotatably coupled to the first ring gear box; anda second drive shaft having a first shaft end rotatably coupled to the second actuator gearbox and the second shaft end rotatably coupled to the second ring gear box, wherein the actuator is configured to simultaneously control the first and second actuator gearboxes such that the first and second rotational outputs are simultaneously transferred to the first and second ring gearboxes, respectively, to circumferentially rotate the synchronization ring.
