The Simulation Analysis of Flow Resistance for Hydraulic Pipe of Helicopter Actuator

In order to study the influence of flow resistance which in hydraulic pipe for the problem of non-synchronous when the left and right actuators of a helicopter expand or release. The simulation model of flow resistance for test hydraulic pipe was established in this paper, and the way of simulation analysis had obtained based on the correction by test data. The simulation of flow resistance for hydraulic pipe of left and right actuators was taken in this way. According to the results, a reliable accuracy of flow resistance in hydraulic pipe could be calculated by the method which was obtained in this paper. And the flow resistance of right actuator pipe was 6% higher than left.
