Evaluation of Wall Interference Assessment and Correction Techniques

Abstract

Evaluation of wall interference correction procedures was performed using experimental data. The correction procedures incorporated the use of measured data made on an interface near the tunnel wall and the use of two flow- field solvers, a transonic small disturbance solver and an Euler solver. Interference corrections were calculated for data obtained in Tunnel 1T with varying amounts of interference. Results are given for representative subcritical, mildly supercritical, and supercritical flows. Calculated interference levels are compared to experimental interference levels between the interference-free reference data from Tunnel 4T and the data with interference from Tunnel 1T. Keywords: Wall interference; Transonic testing; Wind tunnel data; Flight performance prediction; Assessment techniques; Correction techniques.
