Mass spectrometric gas composition measurements associated with jet interaction tests in a high-enthalpy wind tunnel

Knowledge of test gas composition is important in wind-tunnel experiments measuring aerothermodynamic interactions. This paper describes measurements made by sampling the top of the test section during runs of the Langley 7-Inch High-Temperature Tunnel. The tests were conducted to determine the mixing of gas injected from a flat-plate model into a combustion-heated hypervelocity test stream and to monitor the CO2 produced in the combustion. The Mass Spectrometric (MS) measurements yield the mole fraction of N2 or He and CO2 reaching the sample inlets. The data obtained for several tunnel run conditions are related to the pressures measured in the tunnel test section and at the MS ionizer inlet. The apparent distributions of injected gas species and tunnel gas (CO2) are discussed relative to the sampling techniques. The measurements provided significant real-time data for the distribution of injected gases in the test section. The jet N2 diffused readily from the test stream, but the jet He was mostly entrained. The amounts of CO2 and Ar diffusing upward in the test section for several run conditions indicated the variability of the combustion-gas test-stream composition

Lucile Godbold: An Article in the South Carolina Historical Magazine - Accession 1063 - M479 (529)

This collection consists of a copy of The South Carolina Historical Magazine for April 2001 which contains an article titled “Setting The Mark : Lucile Godbold and The First International Track Meet For Women” by Jane P. Tuttle. The article was written about the life and athletic career of Lucile Ellerbe “Ludy” Godbold (1900-1981) who was a 1919 and 1920 graduate of Winthrop College. Ludy won a gold medal in the shot put, a bronze in the javelin throw, and finished fourth in the 300 meter and 1000 meter race at the first International Track Meet for Women in Paris in 1922. This meet is considered the forerunner of women’s Olympic competition. Her Gold medal winning throw in the shot put broke the world record. She taught at Columbia College in Columbia, South Carolina for 58 years and was the first woman elected to the South Carolina Athletic Hall of Fame in 1961.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/2061/thumbnail.jp
