Simple Aerodynamic Modeling for Estimating Static Aeroelastic Deformation of Wind-Tunnel Models

Abstract

Effects of static aeroelastic deformation of a wind-tunnel test model on the aerodynamic characteristics are discussed in supersonic wind-tunnel tests. The static aeroelastic deformation of the main wing of a supersonic airplane model in the JAXA 1m×1m supersonic wind-tunnel is estimated by the iteration of the full-potential aerodynamic analysis and the FEM structural analysis. The estimated deformation corrections improve the agreement of the measured and predicted aerodynamic performance of the model. Some simple aerodynamic load estimation models are constructed with a few aerodynamic calculation results in order to improve the efficiency of the static aeroelastic deformation estimation for practical applications.
