Aerodynamic test and analysis of wrap-around fins at supersonic mach numbers utilizing design of experiments

摘要

The aerodynamics of wrap-around fins (WAFs) are influenced by various factors, including Mach number, length-to-diameter (L/D) ratio, fin sweep angle, fin root chord length, and fin thickness. This paper presents the results of an investigation into the effects of these factors on WAFs at supersonic Mach numbers. This effort was conducted to further define WAF flight characteristics. The design of experiments (DOE) test approach was used to determine the feasibility of DOE in extracting aerodynamic coefficients from spark range testing, as well as to provide a measure of cost savings.
