The enhanced ability to predict the remaining useful life of helicopter drive train components offers potential improvement in the safety, maintainability, and reliability of a helicopter fleet. Current existing helicopter health and usage monitoring systems provide diagnostic information that indicates when the condition of a drive train component is degraded; however, prediction techniques are not...
The enhanced ability to predict the remaining useful life of helicopter drive train components offers potential improvement with regards to safety, maintainability, and reliability of a helicopter fleet. Current existing helicopter health and usage monitoring systems provide diagnostic information that indicates when the condition of a drive train component is degraded; however, prediction techniques...
A robust processing technique for diagnosing and predicting a recipient fault of static components of mechanical systems is presented. In particular, we demonstrate the technique (methodology) to the loosened bolts on the elevation control motor (ECM) of the Common Remotely Operated Weapon Station (CROWS) in order to prevent a disastrous fault or failure in the gear mechanism that loose bolts could...
The method of moments, implemented in 2.5-D for multilayer antenna structures, or implemented as a fully 3-D solution of Maxwell's equations, is a popular method for microwave antenna simulations. Commercial software was used to simulate an aperture-coupled patch and a pin-fed patch antenna element. The simulation results are compared with experimental data measured for antenna prototypes having finite...
