Abstract
The thrust reverser actuation system is used to control and drive the aircraft thrust reverser deployment and retraction,thereby enhancing landing safety.The synchronization of the actuation has a direct bearing on the efficiency of the aircraft reverse thrust and landing safety.Through a comprehensive analysis of the synchronization requirements of the hydraulic thrust reverser actuation system and an exploration of synchronous actuation architectures,a scheme of the hydraulic thrust reverser synchronous actuation system is proposed.Subsequently,the system mathematical and AMESim simulation models are established.These models are utilized to simulate and analyze the impact of various operating conditions,asynchronous loads,and flow control valves on the displacement synchronization of the system.The results reveal that,in comparison to the synchronous scheme of diversion valve and throttle valve,the flow rate of the speed control valve scheme is less affected by the system operating conditions.Furthermore,the load has lesser impact on the synchronization of the system operation.Consequently,the adoption of a speed control valve scheme based on constant flow control can achieve the thrust reverser actuation system deploying and stowing synchronously under different operating conditions.关键词
