A browser-based preliminary sizing wizard for fixed-wing aircraft, covering the full conceptual design sequence from category selection through power plant estimation.
Live tool → medbaazaoui.github.io/Aircraft-Sizing
Works through 9 sequential steps that mirror the conceptual design process taught in aerospace engineering programs and used in early-stage aircraft development:
- Aircraft category — FAR Part 103 ultralight, LSA, GA single/twin, regional turboprop, jet transport
- Mission & weights — payload, range, fuel fraction estimation via Breguet-derived methods
- Wing geometry — aspect ratio, taper, sweep, area, span, and stall speed
- Fuselage sizing — length, fineness ratio, wetted area
- Tail surfaces — horizontal and vertical tail sizing via volume coefficients
- Airfoil selection — NACA 4-series library with lift curve slope and Clmax data
- Propulsion — power loading, thrust-to-weight ratio, engine sizing
- Performance check — cruise speed, climb rate, and range cross-verification
- Summary & export — full parameter sheet, 2D three-view SVG silhouette, CSV/JSON dual-unit export
All calculations run client-side. No data is sent anywhere. No login required.
- Aviation students working through a first conceptual design exercise
- Homebuilders and kit aircraft designers doing early feasibility checks
- Engineers wanting a quick sanity-check on weight fractions and geometry before moving to CAD
- Anyone curious about how a paper airplane turns into real numbers
- Single HTML file, no dependencies, no build step
- Session system supports up to 6 named design snapshots with save/restore
- Silhouette engine draws a calibrated 2D three-view from computed geometry parameters
- All outputs available in both SI and imperial units
