Abstract:

Development of photopyrometry systems employing state-of-the-art image intensifier devices has extended the lower limit for model surface temperature measurements in the AEDC Hyperballistic Range G, for either free- flight or track-guided mode of operation, from 1,900 K to 1,250 K. Photographic resolvabilities object plane for free-flight and track versions of these photopyrometers are 300 micrometers at best and 150 micrometers, respectively. Track-compatible laser photography systems have been developed that provide object-plane resolvability of 25 micrometers as compared to 200-micrometers resolvability for similar systems used in free-flight work. Stereo photography systems and an ultra-high-speed 10 to the 7th power frames per second sequential laser photography system have been developed and applied in Track K.
