【 摘 要 】

This report documents the flight qualification testing of the Dallas/Maxim iButton temperature logger, model DS1922L, for internal mounting to the W80 Air Launched Cruise Missile (ALCM). A single test was performed utilizing a Labworks Inc. LW-140-110 electro-dynamic vibration system in Building 131, Room 2272, at Lawrence Livermore National Laboratory, Livermore, California. Two DS1922L temperature loggers were tested simultaneously, one horizontally and one vertically. The test consisted of random excitation in the vertical axis for 5-hours. The test spectrum used is a shaped random spectrum defined by the Boeing Company for flight qualification of all modifications flown on ALCM flight tests. The spectrum is defined from 10 to 2000 Hz with a 8.52 g RMS magnitude. The spectrum is given in Table 1 and shown graphically in Figure 1.1.
