Reliability Design Prediction Studies With Reference to Jet Propulsion 640392
The reliability design review as a highly disciplined, organized approach to failure mode/failure consequence studies is reappraised in light of jet engine design and development experience. Reliability design prediction techniques based on two approaches are described.
The failure rate estimate for controls and accessory parts based on historical data with similar devices under similar conditions or modified from the reference value by suitable modifier.
The stress-strength probability density interference approach for engine structural parts.
Limitations of the approaches are highlighted; the benefits are discussed as these techniques assist the design engineer toward achieving higher levels of reliability earlier in programs.
