Extended Aging Theories for Predictions of Safe Operational Life of Critical Airborne Structural Components
| AUTHOR | Nasa, National Aeronautics and Space Adm |
| PUBLISHER | Independently Published (09/19/2018) |
| PRODUCT TYPE | Paperback (Paperback) |
Description
The previously developed Ko closed-form aging theory has been reformulated into a more compact mathematical form for easier application. A new equivalent loading theory and empirical loading theories have also been developed and incorporated into the revised Ko aging theory for the prediction of a safe operational life of airborne failure-critical structural components. The new set of aging and loading theories were applied to predict the safe number of flights for the B-52B aircraft to carry a launch vehicle, the structural life of critical components consumed by load excursion to proof load value, and the ground-sitting life of B-52B pylon failure-critical structural components. A special life prediction method was developed for the preflight predictions of operational life of failure-critical structural components of the B-52H pylon system, for which no flight data are available.Ko, William L. and Chen, TonyArmstrong Flight Research CenterLOADS (FORCES); CRITICAL LOADING; STRUCTURAL DESIGN; SERVICE LIFE; PREDICTION ANALYSIS TECHNIQUES; B-52 AIRCRAFT; FAILURE; PROVING; PYLONS...
