Heat Transfer Testing in the NSWC Hypervelocity Wind Tunnel Utilizing Co-Axial Surface Thermocouples.

摘要

In the Naval Surface Weapons Center's Hypervelocity Wind Tunnel 9, heat transfer measurements were generally made using Gardon gages. However, the use of co-axial thermocouples to measure heat transfer offers some important advantages: (1) Calibration stability, (2) Sturdy design, (3) Quick response time, and (4) Ability to be contoured to model surface. Since these surface thermocouples had never been used in Tunnel 9, a shakedown test plan was established to 'iron out' any problems associated with the use of these gages. This publication is a documentation of that shakedown test and its results. (r.h.)
