RESPONSE REQUIREMENTS FOR MILITARY RADIACS. 3. APPLICATION OF A RELIABILITY PREDICTION TECHNIQUE TO A NAVY RADIAC

Technical Report ·
OSTI ID:4804179
An established reliability prediction technique (NAVSHlPS 900-193, TR1100) was applied to a portable radiac, the AN/ PDR-27(J). This theoretical analysis yielded a probable Mean-Time-Between-Failures (MTBF) of 5056 hr with an uncertainty of plus or minus 40 percent. A debugging period of 160 hr was also predicted. The theoretical analysis was confirmed by a laboratory test of 100 instruments operating for 1000 hr. An exponential life curve was demonstrated with an MTBF of approximately 7000 hr. The range for a 90 percent confidence level was from 4,840 to 12,250 hr. The empirical debugging period was about 98 hr. Conclusions are drawn concerning the utility of applying this type of reliability analysis to small portable radiac devices. (auth)
