متن کاملHUMS Condition Based Maintenance Credit Validation
There is an increasing desire to use rotorcraft Health and Usage Monitoring Systems (HUMS) to facilitate Condition Based Maintenance (CBM) approaches to achieve operating cost reductions and other benefits. This type of application must be supported by the certification process, as it is an example of a “maintenance credit”. Guidance material on the process of obtaining a credit is presented in...
متن کاملSecreted trophic factors of Human umbilical cord stromal cells induce differentiation and neurite extension through PI3K and independent of cAMP pathway
BACKGROUND Trophic factors (TFs) play important role during development and adult tissue maintenance. In neurodegenerative diseases (ND) TF supplementation provides protection. Stromal cells (HUMS) derived from the human umbilical cord matrix provide neuroprotection in the ND models of mice. PURPOSE Though TF mediated protection is known, the exact mechanism of protection is not clear. So, he...
متن کاملOptimisation du système de surveillance des hélicoptères pour l'amélioration du diagnostic et de la maintenance. (Optimization of fault diagnosis in helicopter health and usage monitoring systems)
A Health and usage Monitoring System (HUMS) anticipates discrepancies in therotorcraft drive-train, giving the operator an opportunity to perform correctivemaintenance before any damage becomes critical. In addition to usage spectrum analysis,a HUMS deploys vibration monitoring as a means to detect propagating faults. Thismethod consists in comparing in-flight vibration reco...
