... Abstract This paper proposes a vibration-based diagnostic methodology for aircraft bearings based on a joint first- and second-order cyclostationary analysis. The idea is to track the first- and second-order content over a predefined operating speed range, instead of ignoring the later...

... (PHAs) (utilizing over 70 standards and guides) have been performed identifying possible LH2 hazards on-board aircraft. A PHA has also been produced, with industry stakeholder involvement, to understand the major concerns for LH2 use at airports. Gaps in fundamental knowledge and LH2 technology have...

... 11 09 2008 This paper describes a jet engine simulation project assigned to mechanical engineering students in a senior level course in aircraft propulsion systems. The project introduces the students to the methods of engine system analysis and design based on computer simulation...
