基于高速飞行器的气动噪声影响及试验方法

THE RESEARCH ACTUALITY OF AERODYNAMIC NOISE AND ACOUSTIC TEST TECHNOLOGY FOR THE SUPER-SPEEDING FLIGHT VEHICLE

环境适应性是飞行器在预定环境中功能和性能保持正常状态的能力,是飞行器产品的质量特性之一。噪声试验作为飞行器环境试验中的一项重要内容,在飞行器飞行速度增加的同时,其重要性越发的凸显。针对高速飞行器在严酷的噪声环境中可能产生的破环性影响,以GJB150.17A为基础,介绍了噪声源、噪声环境对设备的影响、噪声试验的应用情况以及噪声试验方法,概述了相关试验技术在高速飞行器气动噪声影响研究中的应用。

This paper aims at tile clevastating infection of the Super-Speeding Flight Vehicle in inclement noise envi- ronment. Base on GJB 150.17A, it introduced tile headstrealn of noise, tile infection of tile equipment of noise environinent, tile application and ineasure of acoustic test, and summary of tile application vision for tile SuperSpeeding Plight Vehicle research are also presented.
