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...

This paper presents a survey of engine health monitoring systems for commercial aircraft. The state of practice is explored first, with the purpose of identifying the shortcomings of current systems. The state of the research to address these shortcomings is them surveyed to explore the alternatives. Research and monitoring applications for various other types of engines provide a good basis fo...

Military airspace is increasingly crowded with traditional aircraft competing with new loitering munitions and UAVs. Managing the airspace is therefore more challenging, requiring closer coordination among all the stakeholders. In this paper, we describe the motivation and design of a knowledgebased system that attempts to automate aspects of airspace management, including the detection and res...

As advanced crew support technologies will be available more and more in future military aircraft, it is necessary to have a good understanding of the possibilities in this area, taking into account operational demands, technical possibilities, human factors, evaluation, and validation aspects. A Crew Assistant (CA) is a decision support system for air crew, designed to improve mission effectiv...

This paper describes the use of the mean cumulative function (MCF) and linear estimates based on the recurrence rate to predict the expected number of failures in the future. Reliability data from two repairable units are used to verify the procedure and comparison. The empirical data used in the paper is based on field data gathered during the operational life of the Swedish military aircraft ...

Published near-field analyses of full-scale jet noise are limited, and the application of observed laboratory scale phenomena to full-scale jets is not well understood. To obtain a greater understanding of the connection between radiated noise and source characteristics in full-scale, heated, supersonic jets produced by military aircraft, acoustical measurements were made in the geometric near ...

Nonlinear propagation of noise measured during static run-up measurements of a military jet aircraft is considered. Measurements made of the noise radiation from the F35AA Joint Strike Fighter indicate levels commensurate with finite-amplitude sound propagation, both through a Gol’dberg number analysis and numerical modeling. Comparisons with a nonlinear propagation model based on the generaliz...
