Aeroballistic Range/Track Photographic Instrumentation Development
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.
