|a "The removal of gas material through a capillary opening in a surface is analyzed. The gas, from which the sample is removed, is moving past the surface at supersonic velocities. A variety of possible conditions of temperature, pressure and composition are discussed in an effort to emulate conditions that might be found at the surface of a vehicle traversing the altitude range 100-50 km, or might exist at the surface of a model in the stream of a high enthalpy wind tunnel. Aspects discussed include (1) the throughput of the capillary for conditions of different lengths and different L a (length radius) ratios (2) the total throughput when the surface in question contains many hundreds of these capillaries (3) the effect of the capillaries upon the composition of the analyzed gas (4) the effect of the capillary or capillaries upon the gas stream itself and (5) the implications of the calculations upon the possible implementation of this type of device as an inlet for a mass spectrometer to be developed for analyzing the upper atmosphere."--NTIS
