Research Title : Feature on Wing Flap to Enhance Aerodynamic Efficiency
The development of Product Concept R03 introduces a novel twin-flap system featuring a morphologically enhanced geometrical feature intended to improve aerodynamic efficiency in subsonic aircraft. Initial studies show that the feature produces a sinusoidal efficiency response with changing flap angle, generates unique pressure zones, and shifts optimum operational points across the velocity range. However, the aerodynamic mechanisms responsible for these effects require deeper investigation. This research uses ANSYS Fluent to analyze flow behavior, pressure dynamics, and stability characteristics of the enhanced twin-flap system across varying angles of attack and flap deflections. The study evaluates the performance of the alpha and beta flaps independently and as a coupled system, examining their parabolic contribution patterns and their sensitivity to the 3:2 feature ratio. Using CFD visualization and quantitative aerodynamic metrics, we aim to determine how the enhanced feature influences flow separation, lift, drag, and pressure recovery. The findings will help optimize the geometry for improved aerodynamic performance and provide insight into next-generation adaptive flap technologies.
