Effects of Probe Interference on Side Force of an Inclined Ogive Cylinder

Abstract

The effects of probe interference on the side force have been investigated and quantified for an ogive cylinder at α=45 deg.. The experiment was carried out in an open-loop suction wind tunnel with a rectangular test section measuring 0.6 m (height)×1.0 m (width). The results show that when the probe was in close proximity to the vortices, there was either an attenuation or amplification of the side forces, which caused an error in the side-force coefficient that can reach as high as 20% of the corresponding value without the probe. The reference values for the side-force coefficient C Fy0 were obtained.
