propeller design meaning in English
螺旋桨设计
推进器设计
Examples
- Propeller design method for naval surface ships
水面舰艇螺旋桨设计计算方法 - Varivec propeller designed in the paper is prepared for the model machining and succedent experiment
本文所设计的全方位推进器是为下一步进行试验研究而准备的，在此基础上可以进行模型加工并开展试验研究。 - Over the past 10 years , apc has almost been dominating the aerobatic scene . apc is a very efficient propeller design , especially the tips , which make them very quiet and efficient
过去10年， apc几乎是这行业的狡狡者，其中有很多诀窍让他的产品非常单安静有效率。 - The former is used widely because it avoids complex calculations . the later is used more widely with the developing of the cfd , and it can get more detail data and higher precise result for the propeller design
前者由于没有复杂的运算，也具有一定的工程实用性而被广泛应用，而后者随着计算机的发展而逐步完善，可以的来分析和计算函道螺旋桨的性能。 - In the second part , firstly , the mathematical model for predicting hydrodynamic characteristics of varivec propeller under steady or unsteady condition are present , based on the general propeller lifting - surface theory , potential flow theory and green theorem . then , theoretical calculation methods for predicting hydrodynamic characteristics of varivec propeller designed above paragraphs are present , based on the finite basic solution method , the unsteady vortex lattice method and hess - smith method
在理论计算部分，本文首先基于常规螺旋桨升力面理论、势流理论和格林定理建立了定常和非定常状态下全方向推进器水动力性能计算的数学模型，然后利用有限基本解法、非定常涡格法和赫斯?史密斯方法对全方向推进器定常和非定常状态下的数学模型进行了数值离散，接下来针对前面所设计的全方位推进器进行了数值预报。
