 → Course Description
In this course, an analytical method of the rotor dynamics which causes lift, thrust, and control forces in helicopters will be dealt with. Rotating blade dynamics and its modeling methods will be introduced. A predicting method on the aerodynamic force in hovering, vertical and forward flights,  and the performance calculation methods will be explained. Also, an aeroelastic and aeromechanical stability problems in rotorcraft, and the flight and control characteristics will be briefly mentioned. Finally, vibration and acoustics problem in rotorcraft will be introduced.
