CALIBRATION OF FOUR CONICALLY TIPPED FLOW SURVEY RAKES AT TRANSONIC SPEEDS
Abstract
Four flow survey rakes with one, two, four, and eight, 40-deg conically tipped probes were calibrated to establish pressure coefficient char acteristics at selected Mach numbers and angles of attack and to determine whether intra-probe interference existed at transonic speeds. The calibration was conducted at Mach numbers from 0.70 to 1.40 and angles of attack from -10 to 15 deg. The Reynolds number based on cone maximum diameter varied from 0.14 to 0.17 million. The results showed that pressure differences measured by diametrically opposed orifices were linear with angle of attack for all rake configurations. Total pressures and average static pressures measured on the probes decreased with increasing angle of attack. The two- and four-probe configurations showed no interference effects, and the eight-probe configuration indicated interference effects at all test Mach numbers.
