Aerodynamics & Composite Analysis of UAV - HSTD

# Aerodynamic and Composite Structural Analysis of UAV – HSTD The **CFD** velocity field plot reveals an aerodynamically optimized, streamlined body with well-aligned flow characteristics. The canard wing configuration effectively reduces drag and enhances lift distribution, as evidenced by the smooth velocity contours and the delayed flow separation. A localized velocity and pressure drop near the fuselage's aft section suggests the presence of potential turbulence vortices, warranting further investigation using higher-fidelity turbulence modeling, such as LES or DES, to capture transient flow structures accurately. Minimal boundary layer separation is observed, particularly at the horizontal stabilizers and tail, indicating efficient aerodynamic shaping and favorable pressure recovery. The wake profile exhibits well-detached, organized streamlines, minimizing induced drag and supporting the dynamic stability of the High-Speed Tactical Drone (HSTD). Additionally, the velocity gradient across the wake suggests a stable pressure recovery mechanism, reinforcing horizontal equilibrium at the given velocity and angle of attack. Further analysis with refined mesh resolution and experimental validation can provide deeper insights into optimizing control surface effectiveness and mitigating residual vortex shedding effects. In the **composite analysis** of a UAV fuselage, I evaluated specialized composite panels designed to enhance **flexural rigidity** and compressive strength while maintaining minimal weight. Utilizing FEA, I assessed stress distributions, failure modes, and load-bearing efficiency to optimize the structural performance. The analysis ensured compliance with aerospace standards, focusing on fiber orientation, core materials, and laminate stacking sequences. These lightweight, high-strength panels are widely used in the aerospace and automotive industries for their superior mechanical properties. The results contributed to an optimized fuselage design with improved durability and performance. An image of the **honeycomb** composite panel is also included.
