As demands for higher performance migrated from aircraft engines to land based gas turbines the need for EB welding came along also. The transfer of EB welding processes from relatively thin section components in aircraft turbines to land based aero derivative turbines is straightforward since the basic design and function of both aero and aero derivative components are the same or similar. How...

An analysis was conducted to examine the market visibility of small aircraft as a transportation mode in competition with automobile and scheduled commercial air travel by estimating the pool of users that would potentially switch on-demand air travel due to cost/time saving. These new aircraft greatly increase the practicality of regional aircraft as a transportation mode that can avoid the co...

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...

Whilst existing composite aircraft designs carry additional weight to mitigate the risk of undetected nonconformance to design, new non-destructive characterisation (NDC) methods offer a leaner future for composite designs through complete verification of conformance. The structural-integrity philosophy for composites in current in-service aircraft does not directly accommodate any benefit from...

Traditional commercial aircraft design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight. From the point of view of an aircraft manufacturer, however, this method does not guarantee the financial viability of an aircraft program. A better design approach would take into account not only aircraft performance but also factors such as aircraf...
