In the present paper, an efficient method for three dimensional aircraft pattern recognition is introduced. In this method, a set of simple area based features extracted from silhouette of aerial vehicles are used to recognize an aircraft type from its optical or infrared images taken by a CCD camera or a FLIR sensor. These images can be taken from any direction and distance relative to the fly...

The aircraft inspection/maintenance system, which is influenced by based operators and regulated by the FAA, consists of several interrelated human and machine components. In this process, visual inspection plays a significant role in ensuring aircraft safety. To improve the quality and reliability of aircraft inspection, training and job aiding have been identified as the two most important in...

Best economy (lean of peak or LOP) operation of aircraft engines rather than best power (rich of peak or ROP) has been suggested as a means to reduce fuel consumption in light aircraft with modest speed reduction leading to reduced operating cost (increased miles per gallon), and to reduce cylinder head temperatures (CHTs) leading to improved engine longevity and reduced maintenance cost. A rec...

With the development of aircraft, the amount of monitoring data becomes larger and larger, and the transmission channel bandwidth limitation and the onboard computational capability limitation become challenges for aircraft condition monitoring system. In this study, from the view point of aircraft condition monitoring, a remote fault diagnosis scheme based on compressed sensing is proposed, th...

Automated Prognostics and Health Management (PHM) is a requirement for advanced military aircraft. PHM is the key to achieving true condition-based maintenance. PHM processing strategies include modules for the processing of known nominal and fault conditions. However in real operations there will also occur faults and other off-nominal operations that were never anticipated nor ever encountere...

This is a study of the relationship between aircraft readiness and spares usage at the squadron level, specifically for the F-4B, CH-53, and TA-4F. The study determines the best combination of aircraft, maintenance man-hours, and spare parts for various budgets. Since the availability of spare parts is a big factor in aircraft readiness, a detailed examination was made of the spare parts resupp...
