常用的螺旋桨设计B_P～δ图谱在使用中由于图面为对数坐标,且参数单位采用英制,故给设计工作带来一些不便。此外,B_P～δ图谱一般仅使用其最佳效率线,而图面的大部份对设计工作者来说未免是多余的。本文提出了一种新的螺旋桨设计图谱——最佳效率条件下的螺旋桨设计G_P～Gv图谱。Gp～Gv图谱是以B_P～δ图谱的最佳效率线作基础,全部采用我国常用的各参数单位。它不仅使用简便、结论精确而且直接显示出螺旋桨各要素间的相互联系。
The commonly used propeller design B_P ~ δ map in use because the plane is logarithmic coordinates, and the unit of the parameter is in inch system, so it brings some inconvenience to the design work. In addition, the B_P ~ δ spectrum generally only uses its best efficiency line, and most of the drawings are unnecessary for the designer. In this paper, a new propeller design map is proposed. The propeller design G_P～Gv map under optimal efficiency is presented. The Gp~Gv map is based on the best efficiency line of the B_P~δ map, all of which are commonly used in China. It is not only easy to use, the conclusions are accurate, and it directly shows the interrelationship between the various elements of the propeller.
