Composites are used in a wide variety of markets, including the aerospace, architecture, automotive and military sectors. Along with the increased use of composites, multiple non-destructive testing (NDT) methods have been further developed specifically for inspecting them. Among them, one can single out ultrasonic phased arrays. Research described in this article focuses on the use of ultrasonic...
Traditionally helicopter gearbox failure analysis has been achieved in a number of ways, including the recording of the oil temperature and oil pressure of critical components within the transmission system. Vibration monitoring techniques provide a sufficient level of detail such that all drive train components can be monitored throughout flight. Each indicator relates to specific faults, such as...
The part of the board aircraft equipment contains the great amount of complex subsystems which are mutually connected and controlled by the airplane crew. So a pilot works in such conditions when he must receive and work out a lot of information/data from more panel and outer sources. This information is later used to control the airplane and to fulfill the flight missions. The development in the...
