This paper reports the application of an evidential reasoning (ER) approach, to deal with the evaluation of a contractor, from among different fabrication options of aero-engine equipment. This is followed by a review of current evaluation practices, which begins by highlighting their limitations and then goes on to justify the use of an evidential reasoning approach. The evaluation model is di...

The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

Previous work [9, 7] has established that puffs of air applied to the skin and timed with listening tasks bias the perception of voicing by naive listeners. The current study has replicated and extended these findings by testing air puff effects on gradations of a voicing continuum rather than the voiced and voiceless exemplars of the original work. This design has the advantage of distinguishi...

A scaling relationship for OPDrms that accounts for the fluctuating total temperature profile within a turbulent boundary is derived from the modified Crocco relation. Experimental data from heated, compressible boundary layers at six subsonic Mach numbers in two wind tunnel facilities are shown to be consistent with the theory. The results show that a temperature mismatch between the freestrea...

Innovative development processes are key to the competitiveness of individual companies in the engine industry and to their future relative positions in the value chain. The market characteristics of the engine industry are presented. Based on market requirements, innovative approaches to engineering processes—portal concept and interactive visualization—are shown taking the GP7000 program as a...

This paper reports on the process developed and applied to evaluating web-based collaborative applications that address the ever increasing demand for better and faster communication in engineering between partners and different locations within distributed industrial organisations in the aerospace industry. A three-step approach covering requirements analysis, market screening and tool ranking...
