vortex separation meaning in Chinese
涡流分离
Examples
- Vortex separation tube
涡流分离管 - Wake vortex separation standards are used to prevent hazardous wake vortex encounters which mainly found in the final approach course within the airport termination zone . firstly , this paper analysis the mechanism of the vortex decay and research the influence on the safety of the flight ; then . several different radar wake vortex separation standards are compared and some basic guidelines are developed to establish the future vortex standards . in addition , one kind of advance vortex classification for the civil airplane is proposed . secondly , an encounter hazard model which established for the following aircraft and a simple vortex decay model which mostly concern with the proceeding one are developed ; and a safe separation model can be derived from the both . finally , through the simulation calculation , the correctness of the vortex classification of different types of aircrafts are tested and proved
本课题对雷达管制条件下的最小尾流间隔标准进行了较为详细的分析和研究;首先对尾流的形成和消散机理以及尾流对飞行安全的影响做出了详细的分析,然后就目前实行的几种不同的最小尾流间隔标准进行了比较和分析,提出了相关的几条准则和一种改进的机型尾流分类标准;在这之后,采用理论分析和统计数据分析相结合的方法,建立了尾流危险遭遇基本模型和尾涡消散模型;并在此基础上对民用航空不同机型的尾流分类的合理性进行了计算和评估,为最小尾流间隔标准的确定和改进提供了初步的理论依据。 - In lifting - surface theory , the non - liner phenomena of the trailing vortex in the transition wake area and of the tip vortex separation are considered . in surface panel method hyperboloidal quadrilateral panels are employed and the morino ' s analytical formulation is used to determine the influence coefficients . the more reasonable pressure kutta condition is satisfied at the trailing edge of propeller blade
在计算中,对于升力面理论,本论文考虑了过渡区尾涡收缩和叶梢分离的非线型现象的影响;对于面元法,本论文采用的是计算较为简便的基于扰动速度势的基本公式及双曲面形状的面元,在桨叶随边满足更趋合理的压力kutta条件,并用morino导出的解析公式计算面元的影响系数的快速有效的数值预报方法。
