Reliability Model for Miniature Blowers Per MIL-B-23071B.

Abstract : A statistical review of life test failure data of over 2000 electronic cooling fans and blowers covered by MIL-B-23071B was conducted. The approach followed and the results obtained are discussed. A mathematical reliability model was established for the prediction of blower life as a result of the analysis. A procedure is presented for predicting the mean time to failure and failure rate of miniature fans and blowers.
