エンジンに結合されたプロペラ性能の迅速自動計算法

抄録

A quick automatic method is presented for evaluating a propeller performance combined to an engine. The formulation is obtained through drastic simplification by retaining the essential parts only. A scheme —“thrust-consistent scheme”— is constructed for the part of propeller analysis. Accuracy-examination has been made both for static and forward moving conditions, and confirmed to be within ten% errors. One example of application to an engine-propeller combination is presented, which shows that the present method is much convenient to select the best set of several parameters such as diameter, solidity, and pitch etc.
