D09 Large Passenger Aircraft Design

Delft University of Technology Group D09 · Aerospace Design & Systems Engineering

A five-work-package TU Delft aircraft-design project spanning sizing, aerodynamics, load cases, wing structures, damage tolerance, and aileron reversal.

Group D09 developed a large passenger-aircraft concept through a sequence of systems-engineering work packages. The work moved from initial requirements and sizing into external geometry, Class II weight and drag estimation, critical load cases, preliminary wing structures, and detailed wingbox design.

My documented contribution covered aircraft design and Class II estimations, critical load-case analysis, aileron-reversal analysis, final wingbox design, technical figures, and report integration. The project archive also contains my CATIA flap-mechanism and wing-section work.

Structural design results

The final work package compared six wingbox layouts against buckling, tensile-strength, crack-propagation, and aileron-reversal requirements. Three configurations survived the structural screening; a trade-off selected the final layout with a 6 mm skin, 10 mm stringers, 20 mm spars, a spanwise stringer schedule, and nine ribs at defined stations.

Why this project still matters to me

D09 was an early lesson in engineering traceability. Aerodynamics, loads, structural sizing, CAD, requirements, and technical writing had to remain consistent across a team and across successive design baselines. I present it here as a course design-report series, not as a peer-reviewed publication.
