Give Google Sheets™ wings with AeroSheet: a complete 3D aerodynamics engine embedded in your spreadsheet sidebar. Stop exporting text files from clunky 1990s desktop apps just to update your mass budgets.

Built for UAV engineers, RC scratch-builders, and university design teams who need rapid conceptual wing sizing, trade studies, and aerodynamic sweeps. When your mass budget changes, your stall speed, lift margin, and aerodynamic efficiency update instantly.

**** WING AERODYNAMICS INSIDE GOOGLE SHEETS™ ****

AeroSheet links your aircraft's physical parameters (span, chord, mass, twist) to a custom Prandtl Lifting-Line Theory physics engine, with both linear and nonlinear solvers.

AeroSheet runs a genuine 16-station Prandtl Lifting-Line Theory matrix solve: full spanwise circulation distribution, root-vs-tip stall detection, washout twist effects, and induced drag via Oswald efficiency factor. Built for the subsonic, high-aspect-ratio, low-Reynolds-number regime (Re 50,000–5,000,000) common to RC aircraft, UAVs, and university design competitions.

**** HOW AEROSHEET WORKS ****

THE 3D WING VISUALIZER
Design your wing visually in the sidebar. Adjust sweep, washout (twist), dihedral, and taper ratio and watch the 3D mesh update instantly, with spanwise lift distribution graphs and stall-warning heatmaps projected onto the wing surface.

- Design your wing visually in the AeroSheet sidebar
- Adjust twist (washout), sweep, dihedral, and taper ratio in real time
- View spanwise lift distributions and stall-warning heatmaps on the wing surface

SPREADSHEET-NATIVE AERODYNAMICS FORMULAS
- Type formulas like =AERO_LIFT("4412", 5, 15, 1.2, 0.2) directly into any cell to calculate forces for a given airfoil, angle of attack, speed, span, and chord
- Calculate Lift (N), Drag (N), Induced Drag Coefficients, and Aerodynamic Efficiency (L/D) natively alongside your existing mass and CG calculations

BATCH SWEEPS AND TRADE STUDIES
- Highlight a column of airspeeds or angles of attack and run a full analysis across every row at once
- Compare multiple airfoils (Clark Y, Selig, Eppler, NACA, and more) on the same wing to evaluate performance trade-offs

**** WHAT'S INCLUDED ****

FREE TIER
Generate any NACA 4-digit airfoil. Build and visualize 3D wings. Calculate basic linear aerodynamics and export a single drag polar chart to your spreadsheet.

PRO ACCESS
- Full airfoil database: search and load over 1,600 real airfoils (Clark-Y, Selig, Eppler, and more) directly into your wing
- CAD export: one-click export to CSV, DAT, DXF, and STL for use in CAD or CNC/3D-printing workflows
- Advanced math: batch speed/AoA sweeps, multi-airfoil trade studies, and the full suite of AERO_ custom spreadsheet formulas

PERFECT FOR TEAMS WHO NEED TO:
- Size wings and calculate stall speeds for UAV payloads
- Generate drag polar charts and lift distributions for design reports
- Run airspeed and angle-of-attack sweeps for conceptual trade studies
- Export accurate airfoil splines for CNC or 3D-printed ribs
- Learn lifting-line theory and wing aerodynamics with a live, visual model
