Aviation Propeller Concept Design
Use PropShaper to explore fixed-wing propeller geometry and cruise operating points. This workspace is for conceptual investigation; it is not aircraft propeller certification or full-scale performance validation.
Start from your motor and battery
For RC and small electric aircraft, Quick design asks for motor kV, battery, current limit, weight, cruise speed, airframe drag and the largest prop that clears the ground. It sizes the prop for cruise, checks takeoff thrust, current and tip speed, and fits a standard bore such as APC-style 1/4 inch or a collet adapter.
Separate geometry from installation suitability
Aviation uses the air solver and the same editable geometry as the drone workspace. It does not offer a fabricated full-scale aircraft preset. You can begin with available small-prop reference geometry or your own dimensions, then shape chord, twist and sections. Changing the application label preserves the current air design.
Work at a defined cruise point
Use RPM and advance speed to inspect predicted thrust, power and efficiency. The optimizer can generate chord and twist distributions for a stated design point, followed by re-analysis. Keep the method’s limits in view: small-prop comparisons do not establish performance at aircraft scale, and the solver does not include compressibility or blade flexibility.
Use CAD output for further engineering
Supported geometries export as STL or STEP for inspection and downstream design. Export does not verify a flight installation, fatigue life, vibration, overspeed capability or airworthiness. The Methods page describes what is calculated and the validation actually performed.
Fit your motor
Browse the hub standards: bore, bolt pattern and pin dimensions for common drone, RC, e-foil and trolling motor mounts, with sources.
Understand the calculations
Read the geometry, performance and export methods for assumptions and validation, or use the propeller analysis API.
