Abstract

Steady, unsteady, and aeroelastic computations are performed on an advanced transonic wing configuration, The Bow is modeled by the Navier-Stokes equations, and structures for aeroelastic computations are modeled by the modal equations. The inadequacy of Euler equations and the importance of using the Navier-Stokes equations with a turbulence model is demonstrated for supercritical Bows in the transonic regime, The effect of Mach number on steady pressure distributions is Illustrated,Steady Row computations for transonic wings are compared with wind-tunnel data and also with equivalent conventional wings. Unsteady computations are made in the context of demonstrating the use of the indicial approach for generating aerodynamic data for aeroelastic computations, By using the unsteady data generated by indicial responses, a computationally efficient approach of computing preliminary Butter boundaries is demonstrated. The effect of Mach number on the Butter boundary including the prediction of the transonic Butter speed dip is demonstrated, The Butter boundaries of transonic wings are compared with equivalent conventional wings. Characteristics of the flutter boundaries arecorrelated with aerodynamic Bow characteristics.
