Zusammenfassung:Present status of the AEDC-VKF hotshot tunnels, resulting from development during the past two years, is reported. Development of arc chambers and instrumentation is described. It is shown that good quality force and pressure measurements are made at test section velocities of about 10,000 ft/sec. Correlation of heat transfer rate and velocity measurements shows that heat transfer rates can be measured to within =20%. Limitations of hotshot operation at high enthalpies, due to material problems and excessive heat losses, are discussed. (Author)
