Abstract:

Development of a new photopyrometer instrumentation system, coupled with implementation of a dual-environment test technique, has extended the lower limit for model surface temperature measurements in Hyperballistic Range G from 2,500 to 1,900 K. A highspeed sequential photography system has been developed and used to observe test models in hypervelocity flight through erosive environments experimental evaluations have indicated that a similar photographic system may be applicable for studies of oscillating bow shock waves on certain test models. Model detector systems have been developed and have demonstrated a 93-percent trigger reliability when used in the high-luminosity, blast-tank area of Hyperballistic Range K reliability of previously used systems was 70 percent. Other evaluations have shown that high reliability can be expected in applications of these types of detectors for triggering instrumentation systems in the Range K and Range G guided-track facilities.
