The more important helicopter fuselage aerodynamic design issues and also interactional problems faced by the helicopter airframe aerodynamicist, including performance and handling optimization and special effects caused by rotor downwash impingement on the fuselage at low and high speeds are addressed. The experimental approach remains the principal tool for the solution of helicopter fuselage aerodynamic problems since existing theoretical methods still possess deficiencies such as an inability to model strong three dimensional effects and separated flow areas both on the fuselage and aft of the rotor head. Flight testing is not generally used for helicopter fuselage aerodynamic research work and the use of small scale wind tunnel models remains the principal experimental tool for airframe design. However, CFD methods are being increasingly used to supplement wind tunnel testing and research programs are underway to constantly improve and update techniques in both fuselage and rotor/fuselage interactional aerodynamics.
