2.1 Review of Propeller Design 1cthods<br />
The development of propeller design methods has evolved for a long time. When<br />
propellers were first used for propulsion, very few people knew how propellers operated<br />
and the optimal way to design them. Early designs were following the sleps: trial, error<br />
and imagination. Momentum theory was applied to propellers in the late nineteenth<br />
century. It explained the resulting thrust ofpropellers, but it did not give a detailed reason<br />
for these results [1]. Design for blade strength was based on experience and then later on<br />
simple beam theory to dctcnnine the minimum root thickness and thickness distribution<br />
along the blade span. owadays, finite clement analysis is commonly used to analr-I:e<br />
propeller blades in details to ensure structural soundness.
