Aircraft Cabin Air and Engine Oil - An Engineering View
Journal of Health and Pollution, 9(24):93-98
Dezember 2019
ISSN: 2156-9614

Schlüsselwörter: aeronautics, airplanes, aircraft, aerospace engineering, turbofan engine, aircraft cabins, cabin air, passenger, oil, air conditioning, bleed air

Marker: TI-FF

Zusammenfassung: Almost all passenger jet aircraft today use potentially contaminated bleed air for cabin ventilation. A detailed look at the design of engine bearings, their lubrication and sealing reveals that jet engines leak small amounts of oil by design and not only in failure cases. An equation is derived to calculate the concentration of a possible cabin air contamination. Results show good agreement with measured concentrations of hydrocarbons in aircraft cabins under normal conditions. The solution to the problem of cabin air contamination is a bleed free design. Other partial remedies are briefly discussed.

DGLR-Weiterbildung "Flugzeugentwurf"
Luft- und Raumfahrt, 40(3):38-39
Juli 2019

Schlüsselwörter: Flugzeug, Entwurf, Luftverkehr, Zulassung, Anforderungen, Flugbetrieb, Umwelt, Kraftstoffverbrauch, Kosten, DGLR, HAW Hamburg, Airbus

Marker: TI-FF

Zusammenfassung: Im Flugzeugentwurf vereint sich das gesamte Wissen des Flugzeugbaus. Denn ein neues Flugzeug muss sich sowohl innerhalb des Luftverkehrssystems als auch im multimodalen Verkehr behaupten. Die Flugzeugparameter werden dabei ausgehend von Anforderungen wie Nutzlast und Reichweite so ermittelt, dass die Kosten beim Betrieb des Flugzeugs und dessen Umweltbelastung minimiert werden - eine hochkomplexe Aufgabe. Wie das Vorgehen beim Entwurf von Flugzeugen unter Berücksichtigung der Zulassungsvorschriften genau abläuft, lernen die Teilnehmer des DGLR-Weiterbildungskurses „Flugzeugentwurf", der vom 9. bis 12. September 2019 im ZAL TechCenter in Hamburg stattfindet.

Experimental characterization of multifunctional polymer electrolyte coated carbon fibres
Functional Composites and Structures, 1(2)
12 April 2019

Schlüsselwörter: thermo-mechanical testing, structural batteries, material characterization

Marker: TI- F+F

Zusammenfassung: Multifunctional structures like the structural energy storage are investigated for enhanced lightweight design. Polymer electrolyte coated carbon fibres (PeCCF) function as a battery half-cell, combining negative electrode and structural electrolyte of the energy storage. The new material combination results in unknown mechanical and multiphysical effective characteristics. Looking forward to future multifunctional CFRP structures made from PeCCF, an influence of the multiphysical PeCCF properties on the CFRP laminate characteristics is expected. This paper presents experimental work, focusing on the first multiphysical characterization of state of the art PeCCF. Thereby, physical effects like the thermo-mechanical coupling in a temperature domain of 193 K??<T??<??720 K and the temperature induction by resistive heating are characterized. Important finding is a temperature dependent complex modulus of the material compound, which is related to the temperature dependent mechanical behaviour of the polymer coating. In addition, the ability to adapt and to predict the materials temperature, which is influenced by resistive heating, is shown. Furthermore, first indications of durability of the coating after cyclic mechanical loading are presented. In addition, new experimental methods for PeCCF investigation are proposed, e.g. the application of conductive epoxy resin for electrical connections.
