Abstract
The invention provides an improved propeller blade design by modifying a classic propeller blade design by changing the twist distribution across the propeller blade(s). This is accomplished by increasing the twist of each propeller blade on the inboard portion of the blade compared to a classic propeller design. At a break point, the twist provided across the propeller blade from the break point to the tip of the blade decreases so that the attack angle at the tip of the propeller blade is less than that of a classic propeller blade design.
