ONERA aerodynamic research on helicopters includes basic research in two or three-dimensional flows and studies on rotors. Basic research is carried out for improving the understanding of complicated phenomena which are difficult to study in detail on rotor blades. It concerns in particular the study of steady and unsteady characteristics of airfoils and of problems pertaining to blade tips and to vortex interactions. For the rotors, ONERA developed a computing program for the forces on the blades, based on the acceleration potential method. The problems of unsteady transonic aerodynamics related high speed flight are the object of in-depth studies in cooperation with use the US Army AMRDL (Ames Directorate). (DePo)
