Wind Tunnel Investigation of Joined Wing Configurations

Abstract

The Air Force Research Laboratory's Munitions Directorate is looking to extend the range of its small smart bomb. One proposed idea is to retrofit the bombs with a wing kit, particularly a joined wing configuration. A typical joined wing configuration is one where the wings are positioned in such a way that they form a diamond in both plan and front views. The purpose of this study is to conduct low speed wind tunnel testing of the joined wing configuration to help determine if the joined wing is more beneficial than a single wing configuration. Configurations with differing sweep angles and tip interconnects will be tested in the AFIT 5' wind tunnel. The lift, drag, and pitching moment coefficients will be ascertained. All researched literature indicates that certain joined wing configurations outperform its single wing counterpart.
