Some Numerical Solutions of Inviscid, Unsteady, Transonic Flows over the NLR 7301 Airfoil.

Abstract

Inviscid transonic flows over the NLR 7301 airfoil were calculated using a program based on the unsteady Euler equations. The six cases treated include a subsonic flow, a near-shockless supercritical flow and some supercritical flows with shocks. In each case, steady flows and unsteady flows for pitching oscillations with 0.5 degree amplitude and reduced frequency (k = omega C/2U sub infinity) of approximately 0.2 were calculated. (Author)
