Advanced Theory of Helicopter

  • Overview of the subject

    In helicopters, a rotor system generates lift, thrust, and control forces. In this class, an analytical procedure for its dynamics will be examined. Structural dynamics with beam modeling and aerodynamics for hover, vertical, and forward flight will be investigated. Performance, aeroelastic,and aeromechanical stabilty inherent in helicopters will be analyzed. Flight dynamics and pilot control will be mentioned. Finally, vibration and acoustic noise problems will be also treated.
