Rotary Wing Aerodynamics and Aeroelasticity

A numerical approach for the aeroelastic analysis of helicopter rotors in hover and forward flight is presented. Fluid and structure codes are maintained as separate programs and are time—accurately coupled using TCP/IP socket connections for data exchange throughout run time. This paper includes results of both stand—alone Navier—Stokes hover analyses and Euler computations with fluid—structure coupling applied to both helicopter hover and forward flight.
