摘要
介绍了发动机螺旋进气道的正向设计方法,提出了新的螺旋进气道设计的关键参数,探索出了一种基于对数螺线的进气道的参数化设计方法,并用该方法通过Pro/E软件建立了参数化的螺旋进气道的三维实体模型,该方法可以大幅度减少设计过程所费周期,显著提高螺旋进气道的设计效率。
A positive design is introduced and new key parameters of helical intake port of engine are put forwarded. Then a method of logarithmic spiral-based parametric design for helical intake port of engine is explored. With this method, .a parametric three-dimensional solid model of helical intake port is established by using the Pro/E software.. It proves that the method can significantly shorten design duration and remarkably improve design efficiency of helical intake port.
