Propeller Length vs. Thrust

Location: Forum Stage 5

Presenter: Jeffrey Steinkamp

This presentation will cover the basics of propeller design and functionality with the specific investigation of how propeller length affects thrust performance. By actual hands on propeller thrust testing of different length propellers, a mathematical formula was developed called the “Length Ratio Multiplier”. This derived formula can be a useful tool to help aircraft designers, builders and pilots determine the relative effect of propeller length on thrust performance.
