Range Instrumentation Development
Abstract
Technology work during FY80 resulted in improved instrumentation capabilities for the VKF aeroballistic ranges: an experimental high-speed pyrometry system employing an indium-antimonide infrared detector has demonstrated a capability for in-flight nosetip surface temperature measurements at levels as low as 600 K. The use of narrow bandpass (30 A) optical filters in laser photography systems was found to improve photographic quality during applications where background luminosity was deleteriously intense. A time- resolved spectrometer that covers the wavelength band from 3500 to 6800 A was designed to facilitate the spectral characterization of hypervelocity impact phenomena. A noninterfering model detection system that uses a continuous-wave x-ray source and a scintillation detector was designed and fabricated. Evaluations showed that the system is impervious to high background luminosity levels and that it will provide reliable trigger pulses in range areas where such conditions exist. A high-intensity light source with fast rise time (10 micron seconds).
