条辐叶螺旋桨发明与设计、制作、试验报告

作者依据十余年研究发现的“螺旋桨扭切应力损耗原理”发明“条辐叶螺旋桨”并申报中国发明专利。1996年，按推进效率0.70、0.75、0.80设计制作了3只条辐叶挂机螺旋桨，完成多次挂机船试验，创造出推进效率达到0.786，提高船速12％的高技术指标。

Report on the development,the design,the fabrication and the test of a new type of radial strip blade propeller

Based on author's study in a period of more than ten yearss, a new type of radial strip-blade propeller was developed by the prinaciples of the tortional-shearing stress loss of the propeller and applied for the inventive patent tn China.In 1996, three radial strip-blade propellers whose propulsive efficiencies were 0. 70, 0. 75 and 0. 80 respectively had been designed and fabricated for a outboard motor craft The result of the trial tests of the outboard motor craft shows that the propulsive efficiency of the new type propeller may approach 0.786 and the speed of the outboard motor craft may increase by 12%.
