Propeller Ideal Efficiency at Sandra Dolph blog

Propeller Ideal Efficiency. 2 as a function of fan pressure ratio which is analogous to the commonly used propeller power loading. Η 0 = (t * va)/(2 πn q) • propulsive efficiency: If a propeller of diameter, d, delivers the thrust, t, while the plane travels at the speed, v, it always has a maximum possible efficiency that can be calculated, is below 1 and can not be. Η t = (r t * vs)/(2 πn q) r t= total ship resistance Ideal propulsive efficiency is shown in fig. We still need propellers to generate adequate thrust to propel a vessel at some design speed with some care taken in ensuring some “reasonable” propulsive efficiency. In practice, the propulsive efficiency typically peaks at a level of around 0.8 for a propeller before various aerodynamic effects act to decay its performance as will be shown. This is then used to estimate the induced airspeed in the propeller streamtube, which, in turn, is used to calculate the ideal propeller efficiency.
