Zusammenfassung:
The paper presents the coaxial - rotor helicopter aerodynamic features. The influence of the induced interaction of the rotors on the rotor system aerodynamics in hover and forward flight is shown, which is compared with the equivalent single rotor characteristics. The influence of the coaxial rotors aerodynamic symmetry on the helicopter vibration and trim characteristics is addressed. The coaxial rotor aerodynamic features at the gliding mode and unsteady flapping characteristics of a blade are described. The coaxial type helicopter fuselage layout features are presented. The paper discusses the numerical simulation problems of the coaxial helicopter aerodynamics and its elements.
