Hovering Helicopter Flight Dynamics- A Study of Vertical Motion
This document examines the flight dynamic characteristics of a hovering helicopter in response to collective stick inputs. Only vertical motion is considered. A mathematical model of the aerodynamics/kinematics and rotor system dynamics of a representative aircraft, linearized about the hovering flight condition, is used as a basis for the study. The dynamic behaviour of this model is compared with flight test results for similar inputs and the coefficients are adjusted to improve model performance. The model structure is then modified by the incorporation of additional terms to improve its accuracy. Although no attempt is made to optimize the coefficients of the model using parameter identification techniques, the approach used here provides acceptable results.
