Storage Reliability of Missile Materiel Program: Gyroscope Analysis.

摘要

The report documents findings on the non-operating reliability of gyroscopes. Based on 825million part-hours,the storage failure rate for rate gyroscopes in 348fit (failures per billion hours) with one sided 90percent confidence limit at 412fit. Catastrophic failures are 55percent of the total,spares usage is 3times the failure rate. Elements of gyroscope construction are reviewed and important factors for gyroscope storage reliability are identified. The objective of this program is the development of non-operating (storage) reliability prediction and assurance techniques for missile materiel.
