Abstract
The flat,tailless aerodynamic configuration with a wide speed domain is an important direction for the development of high-performance aircraft configuration technologies.This paper focuses on the lift-to-drag characteristics of the"A-wing"typical aerodynamic configuration across a wide speed domain.Utilizing nested intelligent workflows and statistical sampling optimization design methods based on high-reliability computational fluid dynamics(CFD),this paper carried out multi-design point optimization sampling aimed at wide speed domain flying wing aerodynamic configurations.The purpose is to explore the distribution laws of the maximum lift-to-drag ratio for such configurations under typical transonic and supersonic design altitudes and speeds.The results show that at transonic and supersonic conditions,the maximum lift-to-drag ratio of the optimized aerodynamic configuration exhibits clear regularities as the aspect ratio of the total projected area and the supersonic drag coefficient change.The fitting formula can provide a reference for the selection of design parameters in subsequent similar aerodynamic configurations.关键词
