The invention relates to the technical field of aircraft attitude testing, in particular to a four-degree-of-freedom attitude testing device for a coaxial dual-rotor aircraft, which comprises a support frame, the counterweight mechanism is used for changing the resistance to be overcome when the aircraft ascends; the attitude adjusting mechanism is used for changing the flight attitude of the aircraft; the balance weight mechanism comprises a pulley assembly, a connecting plate is connected to the pulley assembly, and the connecting plate is connected with the posture adjusting mechanism. By arranging the counterweight mechanism, the resistance to be overcome during takeoff and landing of the aircraft can be adjusted, so that the pulling force required during rising of the aircraft can be equal to the total gravity of the aircraft, the real flight takeoff and landing state of the aircraft is simulated, and the test result is more real and reliable. By using the device, the attitude of the aircraft can be accurately tested and measured in a laboratory environment, so that the efficiency and accuracy of research and development are improved.

    本发明涉及飞行器姿态测试技术领域,具体为一种共轴双旋翼式飞行器的四自由度姿态测试装置,包括支撑框架;配重机构,用于改变飞行器上升时所需克服的阻力大小;以及姿态调节机构,用于改变飞行器的飞行姿态;所述配重机构包括滑轮组件,所述滑轮组件上连接有连接板,所述连接板与姿态调节机构连接。通过设置配重机构,能够对飞行器起落时所需克服的阻力进行调节,从而使得飞行器上升时所需的拉力能够等于飞行器总重力,从而模拟飞行器的真实飞行起落状态,使得测试结果更加真实可靠。使用本装置可在实验室环境中对飞行器的姿态进行精确的测试和测量,从而提高研究开发的效率和准确度。
