| Abstract: |
| This paper analyzes the basic problems of moden method of propeller design anddeveloped a computer procedure to design optimum propellers according to Betz optimization theory. Aset of propellers used now are redesigned and the property of the new and the old one are allcalculated at taking off, climbing and cruising coditions. The comparison tunnel tests of scaled modelsof the old and redesigned propellers have been done. The experiment result states that the efficiencyof the redesigned propellers increases by a factor of 3% compared with that of the old one at eachfight condition. |
