风洞投放试验技术的研究现状与应用综述

The compatibility of multi-body separation is a key issue that has always been paid close attention to by the general departments of aviation, aerospace and weapon systems. The aerodynamic force and moment generated by flowfield interference of multi-bodies have an important impact on the compatibility of store separation. The wind tunnel drop test technology based on dynamic similarity is an unsteady test method for the prediction and evaluation of multi-body separation compatibility. Based on the research findings and the author's experience in the study of the wind tunnel drop test technology, this paper summarizes the research status of this technology at home and abroad. The development history of the technology is reviewed, followed by discussions and analyses of the similarity-criteria and scaling-relationship of the wind tunnel drop test. Several key technologies of the wind tunnel test are then summarized, and some thoughts and prospects on the technology are finally presented.
