A practical approach for the indirect prediction of structural fatigue from measured flight parameters

摘要: The perceived benefits of permanent usage monitoring equipment in helicopters include savings the cost helicopter maintenance and a favourable impact on safety fleet management. Unlike indirect fatigue monitoring, direct load relies large number sensors which requires high operational costs. In this paper, learning network has been developed, during training sessions allowed to learn how predict damage indirectly from flight parameters. Each example consists instantaneous induced small time step, parameters measured step. values are evaluated through new approach called progressive model. By considering laws aerodynamics dynamics, combines such way that resulting features can be mapped into fatigue. About 10.5 flying hours data were used train network. After training, wa...
