OVERVIEW

Objective: Compare aerodynamic performance of rectangular and tapered wings at different aspect ratios to inform low-speed aircraft design. Engineering Work: Generated NACA 2415 airfoil and four 3D wing configurations Aspect ratios: 6 and 12; taper ratios: 1.0 and 0.5 Performed angle-of-attack sweeps from −5° to 20° using LLT Evaluated lift curve slope, CLmax, stall angle, CL/CD, and zero-lift drag Analyzed spanwise induced drag, induced AoA, and downwash at 5° AoA

HighlightS

Key Outcomes:

  • Higher aspect ratio wings reduced induced drag and improved efficiency
  • Tapered wings produced smoother lift distributions
  • Identified optimal planform characteristics for low-speed aircraft

Aerospace Engineer | Propulsion, Aerodynamics & Structural Analysis

Aerospace engineer with strong analytical and simulation-driven experience across propulsion systems, high-speed compressible flow, aerodynamics, CFD, and structural fracture mechanics. Demonstrated ability to translate theory into validated engineering insight through system-level design projects, numerical simulations, and parametric studies. Experienced with MATLAB, ANSYS Fluent, Abaqus, Python automation, and aerodynamic analysis tools. Seeking entry-level or associate aerospace engineering roles in propulsion, structures, aerodynamics, or systems engineering.


I’m currently seeking full-time opportunities in aerospace propulsion, systems engineering, or R&D, where I can contribute to mission-driven projects and continue growing as an engineer.


Long-term, I aim to contribute to technologies that enable deep space exploration, especially sustainable missions to Mars. Whether through propulsion, entry systems, or autonomous spacecraft, I want to help shape the future of interplanetary travel through grounded engineering and innovation.
