RESPONSE REQUIREMENTS FOR MILITARY RADIACS. 3. APPLICATION OF A RELIABILITY PREDICTION TECHNIQUE TO A NAVY RADIAC
Abstract
An established reliability prediction technique (NAVSHIPS 900-193, TR1100) has been applied to a recent portable radiac, t e N/PDR-2 (J). This theoretical analysis yielded a probable Mean ime-Between-Failures (MTBF) o5056 hr with an uncertainty of ! 40 percent. A debugging period of 160 hr was also predicted. The theoretical analysis was confirmed by a laboratory test of 100 istruments operating for 1,000 hr. An exponential life curve was demonstrated with an MTBF of approximately 7,000 hr. T e range for a 90 perce 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. (Author)
