摘要
为进一步提高航空气动力教学设计性实验水平,增强对新型导弹、无人机、舰载机和舰船的气动特性研究能力,根据DPIV技术的基本原理和非接触式整体流场成像的特点,将DPIV技术可有效应用于绕流、喷流、分离流等复杂流场结构的显示和研究,探讨将DPIV实验装置应用于HY-750风洞的升级改造,以提高"飞行器表面涡分布"和"翼型表面压力测量"等实验的流场显示效果,促进导弹垂直发射气动干扰、航母飞行甲板扰流流场特性、舰船尾流干扰等海军特色气动问题以及新型作战飞行器气动特性的研究工作。
In order to further improve the design experimental level of aerodynamics teaching and enhance the research capability for the aerodynamic performance of the new missile,unmanned aerial vehicle,shipboard aircraft and ships,and according to the basic principle of DPIV technology and the characteristics of noncontact whole flow field imaging,the DPIV technology can be effectively applied to the display and research of the complex flow field structures such as around flow,jet flow,separation flow,etc.,so as to explore the upgrading of the application of DPIV experimental device to the HY-750 wind tunnel,improve the display effect of the flow fields in the experiments such as＂Aircraft surface vortex distribution＂and ＂Airfoil surface pressure measurement＂and promote the research work for the typical naval aerodynamic problems such as the aerodynamic interference of missile vertical launching,the turbulence flow field performance on the aircraft carrier flight deck,the ship wake interference,etc.,and for the aerodynamic performance of the new combat aircraft.
