This power-matching problem can be solved with a balanced hybrid propulsion system. However, there is a trade-off between wing loading, power loading, the level of hybridization, as well as range and take-off distance. An optimization method can vary design variables in such a way that a minimum of a particular objective is attained. In this paper, a comparison between the optimization results for minimum mass, minimum consumed primary energy, and minimum cost is conducted. A new initial sizing algorithm for general aviation aircraft with hybrid-electric propulsion systems is applied. This initial sizing methodology covers point performance, mission performance analysis, the weight estimation process, and cost estimation. The methodology is applied to the design of a STOL general aviation aircraft, intended for on-demand air mobility operations. The aircraft is sized to carry eight passengers over a distance of 500 km, while able to take off and land from short airstrips. Results indicate that parallel hybrid-electric propulsion systems must be considered for future STOL aircraft.}, language = {en} } @misc{OPUS4-9006, title = {Dimensionen 1-2019: Magazin der FH Aachen University of Applied Sciences - Wir sind FH Aachen!}, address = {Aachen}, organization = {FH Aachen, University of Applied Sciences}, pages = {64 Seiten}, year = {2019}, abstract = {Inhaltsverzeichnis: 6 Wir sind FH! 8 Steigen Sie ein : Wir nehmen Sie mit auf eine Reise der Roboter und Maschinen 18 Grenzenlose F{\"o}rderung : Das Stipendienprogramm geht in das zehnte Jahr 20 Marias neue Kleider : Wissenschaftler unterst{\"u}tzen die Domschatzkammer 24 Die Sprengstoffschn{\"u}ffler : Fliegerbomben im Erdreich: Neues Verfahren auf Basis der Neutronenaktivierungsanalyse 26 Geschafft! : Erster marokkanischer Elektrotechnikstudent macht seinen Doppelabschluss an der FH Aachen 28 Maßgeschneidert : Dr. Denise Milinnus vom INB entwickelt digitale Biosensoren f{\"u}r die personalisierte Medizin 32 Auf H{\"o}henfl{\"u}gen : Tobias Barth macht außergew{\"o}hnliche Luftaufnahmen 36 {\"U}ber alle Berge : Talentscouting er{\"o}ffnet neue Wege 38 Der etwas andere Reisef{\"u}hrer : FH-Studentinnen entwerfen Stadtplan f{\"u}r junge Menschen 42 Warum kommt mein Zug zu sp{\"a}t? : FH-Experten im Interview {\"u}ber Probleme und L{\"o}sungen der Schiene 48 Der Alina-Weg : Alina Richter promoviert bei der Volkswaren-Konzernforschung 51 Selbst ist die Frau : Die 31-j{\"a}hrige Meral Dural studiert erfolgreich Elektrotechnik am FH-Campus J{\"u}lich 52 An der Schnittstelle : INFORM-Professur f{\"u}r angewandte Mathematik und Informatik 53 Kopfnuss 54 Einmal scannen bitte : Forschungsprojekt am MASKOR-Institut wird vom Bund gef{\"o}rdert 56 Inspiriert vom Tier- und Pflanzenmeer : FH-Absolventin Lara Bispinck gewinnt "Future Impact Maker" 60 Schmusekurs mit dem Tiger : FH Aachen f{\"u}hrt Kooperationsverbund mit taiwanesischen Hochschulen an 62 Impressum}, language = {de} } @article{OezsoyluKizildagSchoeningetal.2019, author = {{\"O}zsoylu, Dua and Kizildag, Sefa and Sch{\"o}ning, Michael Josef and Wagner, Torsten}, title = {Effect of plasma treatment on the sensor properties of a light-addressable potentiometric sensor (LAPS)}, series = {physica status solidi a : applications and materials sciences}, volume = {216}, journal = {physica status solidi a : applications and materials sciences}, number = {20}, publisher = {Wiley}, address = {Weinheim}, issn = {1862-6319}, doi = {10.1002/pssa.201900259}, pages = {8 Seiten}, year = {2019}, abstract = {A light-addressable potentiometric sensor (LAPS) is a field-effect-based (bio-) chemical sensor, in which a desired sensing area on the sensor surface can be defined by illumination. Light addressability can be used to visualize the concentration and spatial distribution of the target molecules, e.g., H+ ions. This unique feature has great potential for the label-free imaging of the metabolic activity of living organisms. The cultivation of those organisms needs specially tailored surface properties of the sensor. O2 plasma treatment is an attractive and promising tool for rapid surface engineering. However, the potential impacts of the technique are carefully investigated for the sensors that suffer from plasma-induced damage. Herein, a LAPS with a Ta2O5 pH-sensitive surface is successfully patterned by plasma treatment, and its effects are investigated by contact angle and scanning LAPS measurements. The plasma duration of 30 s (30 W) is found to be the threshold value, where excessive wettability begins. Furthermore, this treatment approach causes moderate plasma-induced damage, which can be reduced by thermal annealing (10 min at 300 °C). These findings provide a useful guideline to support future studies, where the LAPS surface is desired to be more hydrophilic by O2 plasma treatment.}, language = {en} } @article{WingensMayPfaff2019, author = {Wingens, Niklas and May, J{\"o}rg and Pfaff, Raphael}, title = {Betrieblich-technische Innovationsans{\"a}tze zur Bremsprobe nach einer Prozess{\"a}nderung}, series = {Eisenbahntechnische Rundschau : ETR ; Zeitschrift f{\"u}r die gesamte Eisenbahntechnik}, journal = {Eisenbahntechnische Rundschau : ETR ; Zeitschrift f{\"u}r die gesamte Eisenbahntechnik}, number = {5}, publisher = {DVV Media Group}, address = {Hamburg}, issn = {0013-2845}, pages = {5}, year = {2019}, language = {de} } @book{TuennemannAzzab2018, author = {T{\"u}nnemann, Thomas and Azzab, Miriam}, title = {Sulla Strada : Workshop Formine 2018}, publisher = {FH Aachen, Fachbereich Architektur}, address = {Aachen}, isbn = {978-3-9820159-0-3}, publisher = {Fachhochschule Aachen}, pages = {122 Seiten}, year = {2018}, abstract = {Impressum | Inhalt 03 Thomas T{\"u}nnemann | Unterwegs...am Wege 04 Projekte 06 Annelie Wirtz | Arrivato 08 Sebastian Rupp | Tracce Passate 18 Henri Boh | Terrazze sopra il lago 28 Hermann Stuzmann | L´Ammissione {\`e} Gratuita 32 Vivienne Scheidz | IL Potere dei Simboli 34 Felix Keller | Strada Infinita 38 Moran Dorner | Catturato nel Posto 42 Kevin Osterkamp | Vortice 46 Kristina Foidle | La Vespa e il Fico 52 Simon Rix | Sognare Sulla Strada 58 Jennifer Sikora | Strada Pietrosa 66 Sabrina Fr{\"o}mbgen | Bolla di Pensiero 72 Miriam Azzab | Il Momento 78 Georg M{\"o}rke | Sentiero stretto 84 Saskia Fr{\"o}mbgen | Nuova Prospetiva 90 Frank Drehsen | A grado a grado 96 Caronlin Gr{\"u}n | Le prospettive 100 Thomas T{\"u}nnemann | Flusso nella Foresta 104 Atmosph{\"a}risches Auf die K{\"u}che | Kulinarisches 114 Carpe Diem | Fotografisches 116}, language = {de} } @inproceedings{BaaderReiswichBartschetal.2018, author = {Baader, Fabian and Reiswich, M. and Bartsch, M. and Keller, D. and Tiede, E. and Keck, G. and Demircian, A. and Friedrich, M. and Dachwald, Bernd and Sch{\"u}ller, K. and Lehmann, R. and Chojetzki, R. and Durand, C. and Rapp, L. and Kowalski, Julia and F{\"o}rstner, R.}, title = {VIPER - Student research on extraterrestrical ice penetration technology}, series = {Proceedings of the 2nd Symposium on Space Educational Activities}, booktitle = {Proceedings of the 2nd Symposium on Space Educational Activities}, pages = {1 -- 6}, year = {2018}, abstract = {Recent analysis of scientific data from Cassini and earth-based observations gave evidence for a global ocean under a surrounding solid ice shell on Saturn's moon Enceladus. Images of Enceladus' South Pole showed several fissures in the ice shell with plumes constantly exhausting frozen water particles, building up the E-Ring, one of the outer rings of Saturn. In this southern region of Enceladus, the ice shell is considered to be as thin as 2 km, about an order of magnitude thinner than on the rest of the moon. Under the ice shell, there is a global ocean consisting of liquid water. Scientists are discussing different approaches the possibilities of taking samples of water, i.e. by melting through the ice using a melting probe. FH Aachen UAS developed a prototype of maneuverable melting probe which can navigate through the ice that has already been tested successfully in a terrestrial environment. This means no atmosphere and or ambient pressure, low ice temperatures of around 100 to 150K (near the South Pole) and a very low gravity of 0,114 m/s^2 or 1100 μg. Two of these influencing measures are about to be investigated at FH Aachen UAS in 2017, low ice temperature and low ambient pressure below the triple point of water. Low gravity cannot be easily simulated inside a large experiment chamber, though. Numerical simulations of the melting process at RWTH Aachen however are showing a gravity dependence of melting behavior. Considering this aspect, VIPER provides a link between large-scale experimental simulations at FH Aachen UAS and numerical simulations at RWTH Aachen. To analyze the melting process, about 90 seconds of experiment time in reduced gravity and low ambient pressure is provided by the REXUS rocket. In this time frame, the melting speed and contact force between ice and probes are measured, as well as heating power and a two-dimensional array of ice temperatures. Additionally, visual and infrared cameras are used to observe the melting process.}, language = {en} } @misc{OPUS4-8740, title = {Dimensionen 1-2018: Magazin der FH Aachen University of Applied Sciences - Grenzg{\"a}nge}, organization = {FH Aachen, University of Applied Sciences}, pages = {62 Seiten}, year = {2018}, abstract = {Grenzg{\"a}nge: Op j{\"o}ck in Vaals mit Peter Sparla Inhaltsverzeichnis 6 "Mr. Vaals": Ein Spaziergang mit Peter Sparla durch die niederl{\"a}ndische Gemeinde 14 Ein Verein hebt ab: Von der Theorie in die Praxis: Die Flugtechnische Arbeitsgemeinschaft will Studierende f{\"u}rs Fliegen begeistern 18 Vom Flugplatzkind zur Ingenieurin: Sarah Hamacher hat Luft- und Raumfahrt studiert und arbeitet jetzt bei der ADAC-Luftfahrttechnik 20 Mit Sonne im Tank durch das australische Outback: FH-Student Enno D{\"u}lberg berichtet von der World Solar Challenge 24 Es steckt mehr dahinter: Eine Eschweiler Firma entwickelt Elektronik-L{\"o}sungen f{\"u}r Anh{\"a}ngerkupplungen - mit Unterst{\"u}tzung der FH Aachen 27 Von Mekn{\`e}s nach J{\"u}lich: Die Geschichte von Rabab Azizi 28 Das blaue Wunder neu erleben: Aachener Tuchtradition soll wieder in Mode kommen 32 Es werde Licht: Markus van Hauten macht spektakul{\"a}re Landschaftsfotos 36 Maschinenbau von morgen: Dr. Julia Kessler forscht zu additiv gefertigten Leichtbaustrukturen 39 Vier Siebenen und eine Eins: Kopfnuss 40 Auf Tuchf{\"u}hlung mit der Praxis: Das ausbildungsintegrierende Studium ist anspruchsvoll und fordernd.
