Aircraft Design • Aerodynamics • Trade Studies
Aircraft design project featuring full CAD modeling, structural drawings, and wing/stabilizer analysis.
The objective was to design a new narrow-body twinjet competitive with the A320neo and 737 MAX, targeting a 5–10% efficiency improvement. The design focused on minimizing fuel burn per seat while maintaining reliability, practical development, and long-term profitability. The project was approached as a system-level problem, where each design decision supported overall performance and business viability.
The three-view layout was developed from trade studies across fuselage, wing structure, landing gear, empennage, flaps, and engine placement. These studies defined the final geometry by balancing aerodynamic performance, structural layout, and overall system integration.
Design Logic
Benchmarked aircraft weight against competitors to define target design range and performance goals.
NACA 63(2)-415 was the selected airfoil based on target lift coefficients and transonic cruise performance requirements.
Used constraint analysis to determine optimal wing loading and thrust-to-weight ratio for design feasibility.
Aircraft Design
Sized to meet passenger capacity and layout requirements while maintaining aerodynamic efficiency, using fineness ratio as a key design parameter.
Designed to meet cruise performance goals while enabling effective takeoff and landing through high-lift integration.
Sized to ensure stability and control, supporting a balanced and controllable aircraft design.
This project improved my understanding of aircraft design as a system-level problem, where aerodynamic, structural, and performance decisions are closely connected. I gained experience using trade studies to guide design choices and balance efficiency, practicality, and performance. In the future, I want to explore more advanced aerodynamic analysis and refine the design with higher fidelity tools to better capture real-world performance.
