Abstract:

Unsatisfactory operation of the TAU-15B infrared target flares had been observed when these flares were employed at high subsonic speeds and high 35,000 ft altitude. The primary difficulty was failure of a significant percentage of the flares to burn after successful operation of the ignition squibs. Since it was believed that age of the flares may have affected their operational performance, this test was conducted to investigate the ignition failure rate of TAU-15B flares which had been in storage since the July October 1960 manufacturing period. Specific objectives of the test were to determine the ignition failure rate during flight at 35,000 ft altitude and mach 0.7 as well as under simulated flight conditions in an altitude chamber. It was concluded that performance of the TAU-15B flares varies from one production lot to another and with altitude and the internal temperature of the individual flares. Results obtained under simulated altitude conditions in the altitude chamber correlated reasonably well with those obtained during airborne tests.
