Wind Tunnel Tests of the Upstream Influence of a Conical Mass Spectrometer Probe.

Abstract

Wind tunnel tests of two configurations of a mass spectrometer high altitude probe are reported. Results show that a 35 degree half angle conical nose has an attached shock wave at M=3 from 25 to 100 km altitude. Spectrographic measurements of the density and temperature perturbations at the probe tip indicate no influence below 70 km altitude with an increasing influence between 70 and 100 km. At 100 km altitude perturbations of temperature and density are still much smaller for the conical probe than for a flat faced probe. (Author)
