Aircraft Conceptual Design System

A browser-based aircraft conceptual design tool built on Raymer, Roskam, and Breguet. Constraint diagram generation, MTOW sizing, and parametric sweep analysis — with every equation auditable and every assumption documented.

Designed for UAV and eVTOL startups, university programmes, and independent engineers who need rigorous first-pass sizing with zero setup.
