Abstract

The invention relates to a scale model device for simulating a gyroscopic effect of an engine rotor. The device comprises an engine nacelle scale model, a servo motor, a motor support, a rotating disc, and a control system. The engine nacelle scale model has an engine nacelle scale model skeleton, and the motor support is connected to the engine nacelle scale model skeleton. The servo motor is connected to the motor support, and the servo motor is connected to the rotating disc and is used for driving the rotating disc to rotate. The control system is connected to the servo motor and is used for controlling the forwarding and reverse rotation and the rotational speed of the servo motor. The device can achieve the following beneficial effects that the device achieves the effective simulation and precise control of the gyroscopic effect of the engine rotor through the limited space of the engine nacelle scale model.

Description

technical field [0001] The invention relates to a scale model device for simulating the gyro effect of an engine rotor. Background technique [0002] Most modern large-scale transport aircraft use turbofan engines with large bypass ratios. These engines usually use large-diameter fans and high-speed rotating core engines. The rotor gyroscopic effect generated during their operation will have an impact on the structural dynamics of the aircraft, and then have an effect on the aeroelastic properties of the aircraft. The above effects have become factors that must be considered in the design of large transport aircraft, and the scale model wind tunnel test method is used to verify their effects. In the scale model wind tunnel test, it is a technical difficulty to effectively simulate the gyroscopic effect produced by the rotation of the real engine rotor. [0003] At present, there is no design of a scale model device for simulating the gyroscopic effect of an engine rotor in...
