The dynamics model of a single disk Jeffcott rotor system in an aircraft is established. The influence of aircraft flight velocity and acceleration variation on the amplitude response curve of the isokinetic rotor in a flying vehicle is studied. The rotor response of the rotor in a sinusoidal flight in the vertical plane is simulated Amplitude response. The results show that most of the flight operations, including speed changes and acceleration changes, will lead to significant changes in the amplitude response curve of the medium-speed rotor in the aircraft. The response of the rotor system is obviously affected by the flight law when the aircraft makes the sinusoidal flight in the vertical plane Impact. The range of motion and the action cycle of the aircraft are different, and the amplitude transient response of the rotor at constant speed in the aircraft is completely different.
