Preventing stall is a crucial challenge in fixed-wing aviation as it significantly impacts flight safety and performance. This research focuses on the development of morphing wing technologies to improve high-lift devices in small Unmanned Aerial Vehicles (UAVs). The main aim is to design, develop, and test a morphing wing that enhances lift and provides better resistance to stalling. This research proposed the SPICS (Slotted-Pillar Internal Compliant System) morphing mechanism through several iterations to achieve a parabolic deflection. Using Fused Deposition Modeling (FDM) 3D printing technology, a test section with a 40 cm span and 20 cm chord length was manufactured. The SPICS design was subjected to testing in a controlled wind tunnel environment, where it demonstrated the ability to effectively adjust its camber. This adjustment led to an improvement in the lift coefficient ( \({C}_{L}\) ), achieving a \({C}_{{L}_{max}}\) of up to 1.65. Moreover, the stall angle increased from 10° to 14°, indicating better stall resistance. During the stall tests, the SPICS successfully recovered from stall conditions and maintained its \({C}_{L}\) at higher angles of attack. These findings suggest that the SPICS mechanism could be a promising alternative to conventional articulated flaps for small-scale UAVs.
