Pressure Distribution Measurement around Hypersonic Delta-Winged Semicone : Measurement by Means of Magnetic Tape

Abstract

This paper describes measurements of pressure distribution around a semicone with a delta wing traveling at the hypersonic speed of Mach 10. The semiapex angles of the delta wing and semicone are 30 deg and 15 deg, respectively. The measurements are carried out under the conditions in which the angles of attack are 0 deg, 10 deg, and 20 deg. In this study, the pressure distribution measuring method using magnetic tape has been improved to be suitable for measuring pressure distribution around hyper-sonic vehicles. The pressure distributions are measured by utilizing the improved method.
