Co-simulation Investigation on Hydraulic Thrust Reverser Actuation System

As an important part of thrust reverser system, the thrust reverser actuation system of aero-engine is of great significance to the aircraft deceleration of the landing. In order to investigate the moving performance of thrust reverser actuation system, the kinematics and dynamics analysis were carried out, and then the mathematic model was established. The co-simulation based on AMESim and Simulink was used to conduct the simulation investigation which is concerned with system buffering characteristic, synchronization performance and temperature effect of hydraulic medium. The results of the simulation investigation indicate that the co-simulation model of thrust reverser actuation system is helpful to estimate the system operation, and is also an effective analytical tool for the system performance assessment. The buffering model used for the thrust reverser actuation system contributes to reduce the actuator piston of system velocity, less than 0.13 m/s, which is conducive to weaken the violent impact on piston and cylinder. The maximum non-synchronization occurs in the extreme positions of system deployment and stowage. Ensuring the pressure synchronization, i.e. flow synchronization, is helps to improving the synchronization performance. The thrust reverser actuation system can also run with the low medium temperature, −54 ℃, but with the low velocity.
