US 12,589,890 B2 · Testing device and testing method of composite blade tilt rotor power assembly

Abstract

A testing device and a testing method of a composite blade tilt rotor power assembly are related. The testing method includes the following steps: installing a tilt rotor flight power assembly on a flange platform of a testing device through a connector; confirming normal operation of an external power supply, the tilt rotor flight power assembly and a data acquisition computer; starting the tilt rotor flight power assembly, and controlling a tilt motor to rotate a cantilever shaft according to a tilt angle instruction; and recording the energy consumption and the tensile forces and torques in x, y and z directions of the tilt rotor flight power assembly by the data acquisition computer in real time. The testing method has the beneficial effects that the processes of starting, starting and stopping, hovering and descending can be simulated for the composite blade tilt rotor power assembly which is a core driving component of a vertical take-off and landing type electric driving hovercar, and the flight performance of the hovercar can be tested. The testing method can also be used for cold rotation test, take-off strategy verification test, hover strategy verification test, durability test and acceleration performance test of the composite blade tilt rotor power assembly.
