The hydraulic thrust reverser actuation system is used to control the deployment and retraction of the thrust reverser device. It generates reverse thrust when the aircraft lands to reduce the taxiing velocity of aircraft and improve the safety and reliability. In order to deeply explore the movement performance of the hydraulic actuation system of thrust reverser device, the deploying and stowing characteristics of hydraulic thrust reverser actuation system at design point and non-design point, as well as the asynchronous external loads and the performance changes under different oil temperature were investigated. The velocity characteristics and synchronicity changes in different working conditions were also analyzed. The experimental investigation is shown that, at design point, the system synchronization is good. After deviating from the design point, the system synchronization becomes worse. The mechanical synchronization using the synchronous flexible shaft is obviously better than hydraulic synchronization using throttle valve. The synchronous flexible shaft contributes to weaken the asynchronous error between the actuators. When the asynchronous load is zero, the unilateral synchronization and bilateral synchronization is better than 0.3% and 3.5% respectively. When the asynchronous load exceeds 800 N, the greater asynchronous load causes the greater unilateral synchronization error and bilateral synchronization error. Additionally, both oil pressure and temperature will cause the system performance to deviate from the performance at design point.
