| Abstract: | A method is presented to evaluate changes in airfoil characteristics resulting from extension of chord at trailing edge of propeller blade section. Method determines changes in angle of zero lift, angle of attack, and difference in these angles (upon which design lift coefficient depends) as function of angle and length of trailing edge extension. Treatment is based on thin-airfoil theory and is concerned only with mean camber line of section. Examples and detailed computations illustrate application of method, which is applicable to all propeller sections. Characteristics obtained were in perfect agreement with data calculated by exact method of arbitrary airfoil theory. |
