This chapter introduces conceptual and preliminary design concepts for a conventional helicopter. The subject of rotorcraft design is too vast to the presented in a single book chapter, and thus we limit the presentation to a few key design aspects, as discussed in our lecture series. We provide a top level discussion of the multi-disciplinary team-work required, including analysis of design requirements, costs, risks and compliance. The design consists of a main rotor system and the associated tail rotor, both of which require sizing, with determination of the number of blades, rotor solidity and angular speeds. We discuss concepts for rotor blade design, which is essential in reducing shaft power, improving overall rotor performance, limit vibrations and noise. Concepts are shown for fuselage sizing, including assessment of aerodynamic drag We discuss items such as the empennage (horizontal and vertical stabilisers) and the landing gear.
