The influence of mid-chord battle damage on the aerodynamic characterstics of two-dimensional wings

摘要

This paper briefly considers the method of simulating gunfire damage to a wing and outlines the key basic assumptions used in modelling. The results of qualitative and quantitative investigations into the Aerodynamic characteristics of a wing damaged at quarter chord are Then presented. The results are discussed in terms of flow mechanisms, Change to surface pressure distributions and increments in lift, drag And pitching moment coefficients. For the damage wing, the influence On force and moment coefficients was attributed to flow through the Damage.
