wake vortex meaning in Chinese
尾列
尾涡流
Examples
- Engineers are working on ways to detect hazardous wake vortices so pilots can avoid them or to design aircraft that leave safer skies behind them
工程师正在研究，想找出有效的点子，侦测危险的机尾涡流，或设计不会危及后方空域的安全飞机。 - Because wake vortices can persist in calm air for several minutes ( extending for as far as eight miles ) , the federal aviation administration requires minimum distances between aircraft , based on size
机尾涡流可以在无风的空气中停留几分钟，向后延伸达12公里，所以美国联邦航空总署按照飞机大小而规定了飞机之间的最小安全距离。 - An experimental study on the aerodynamic characteristics of new concept car is conducted by model wind tunnel test , covering the pressure coefficient and wake vortices on longitudinal symmetry plane , as well as aerodynamic forces and moments under different yaw angles
摘要用模型风洞对新概念车在不同横摆角下纵对称面上压力系数、整车气动力和气动力矩的变化以及纵对称面尾部流态分布进行了试验研究。 - 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。
