摘要
介绍和分析了国内外栅格翼的研究现状和技术难点。为了详细了解栅格翼气动布局栅格内部的流动特性,以及其与阻力设计满足飞行器性能要求的栅格翼,本文开展了几种不同单栅格形状外形的气动特性数值计算。针对传统数值计算中遇到的栅格翼计算网格生成困难、工作量大的问题,利用非结构空间直角网格对于复杂外形易于生成的特点对单个栅格的外形进行了初步选型研究。对于常规导弹和栅格翼导弹的气动性能进行了对比。
Introduction and analysis of the domestic wing of the grid status and technical difficulties. To learn more about grid fin aerodynamic flow characteristics within the grid layout and design with the resistance of the grid to meet the performance requirements of aircraft wings, this one carded out in several different shapes form the aerodynamic characteristics of grid numerical calculation. In this paper, the traditional numerical calculation of grid fin encountered difficulties in grid generation, the problem of heavy workload, the use of non-rectangular grid structure space generated for complex shape features easy to form a single grid of a preliminary selection. For conventional missiles and missile wing aerodynamic performance of the grid were compared.
