The unit covers the fundamental aerodynamic and dynamic aspect of rotor systems for powered and non powered rotors. The blade flapping characteristics in forward flight for articulated and semi-rigid rotors is analysed and design issues associated with helicopter vibration and ground resonance are dealt with in some detail. With particular emphasis on the future trends in rotorcraft technology and configurations this unit considers aspects of fundamental design issues beyond the conventional helicopter. The scope of the material covered in this unit is more extensive than the H level unit but still includes fundamental aspects of rotor system behaviour, including: Rotor configurations; Aerodynamics of the rotor in axial flight; Aerodynamics of the rotor in forward flight; Aspects of rotor design; Aspects of rotor performance; Rotor hinge systems; Fundamental mode flp-wise and lag-wise motion of the blades; The semi-rigid rotor; Vibration; Ground resonance; Future trends in technoloy and configuration.
Aims:
The aim of this unit is to introduce the fundamental aerodynamic and dynamic aspects which govern the behaviour of the helicopter and to gain an understanding of the inherent performance limitations of conventional designs. Upon successful completion of the unit the student will:
