摘要
结合对齐柏林NT飞艇螺旋桨的重新设计,阐述了低空低速飞艇推进螺旋桨主要参数的确定方法。运用Betz优化理论和片条理论发展了一套飞艇螺旋桨的优化设计方法及设计和性能的计算程序。计算结果表明所设计的螺旋桨在巡航状态比原桨效率提高了4%,可见该优化设计方法能为低空低速飞艇推进螺旋桨的设计提供参考。
This paper analyzes the basic problems of propeller for low altitude and low speed airship.A method that can decide the parameters of the propeller are presented and a computer procedure to design optimum propellers according to Betz optimization theory is developed.The result states that the efficiency of the redesigned propellers increases by a factor of 4% compared with that of the old one at cruising conditions.Therefore the optimization method in this paper is a reference for the design of the high efficient propeller of low altitude and low speed airship.
