Wind Tunnel Tests of 3D-Printed Variable Camber Morphing Wing

This paper introduces the realization and wind tunnel testing of a novel variable camber wing equipped with compliant morphing trailing edges. Based on aerodynamic shape mechanisms that were optimized in advance, model called mTE4 was developed, which rigid leading edge, box, edge manufactured by 3D printing technology using three different materials. Due to difficulties detailed design small-scale model, special attention is devoted implementation procedure. Additionally, static dynamic characteristics proposed evaluated ground tests, numerical methods. Then, performance aeroelastic deformation investigated low-speed tunnel. The load-bearing ability device validated continuous outer mold surface found persist throughout entire period. Notably, maximum deflection range 37.9° at airspeed 15 m/s achieved. stall mitigation also achieved periodically deflecting enabling angle delay approximately 1° 13% increase post-stall lift coefficient. Finally, development procedure comparing between experimental results.
