Gollnow, Martin, 2023, "Passenger Aircraft towards Zero Emission with Hydrogen and Fuel Cells", https://doi.org/10.7910/DVN/CURS1U, Harvard Dataverse, V1
Purpose – This project evaluates the feasibility of passenger aircraft designed for Top Level Aircraft Requirements (TLAR) of the Airbus A320 using liquid hydrogen (LH2) and fuel cells to achieve "zero emissions". --- Methodology – An existing preliminary sizing tool for jet and propeller passenger aircraft (CS-25) is modified to include all elemen... |
Schnoor, Max; Arslan, Suna, 2021, "Calculating the Wing Lift Distribution With the Diederich Method in Microsoft Excel", https://doi.org/10.7910/DVN/UK2SIV, Harvard Dataverse, V4
Aim of this project is to provide the Diederich Method for calculating the lift distribution of a wing in a Microsoft Excel spreadsheet based on didactic considerations. The Diederich Method is described based on primary and secondary literature. Diagrams are digitized so that the method can run automatically. To optimize the lift distribution of t... |
Gulani, Schaugar, 2023, "Proposing a Classification for Aeronautics, Astronautics, and Aerospace Sciences", https://doi.org/10.7910/DVN/MZIVRX, Harvard Dataverse, V1
Purpose – This thesis presents an aerospace classification and explains its logic. The classification is checked and presented throughout the thesis in various forms. Furthermore, HTML, PDF, and Excel versions have been made available online. --- Methodology – A review of aerospace classifications was conducted. A classification authored originally... |

Lucht, Dennis, 2023, "Numerical and Analytical Takeoff Field Length Calculations for Jet Aircraft", https://doi.org/10.7910/DVN/QX3MAH, Harvard Dataverse, V1
Purpose - The greater of two distances (Balanced Field Length or Takeoff Distance +15%) results in the Takeoff Field Length (TOFL). The TOFL is a takeoff distance with safety margins according to Certification Standards for Large Aeroplanes by EASA (CS-25) and FAA (FAR Part 25). Simple analytical approximations for the TOFL are checked against more... |
Ottermann, Hartwig, 2023, "Konzeptstudie über die Kompatibilität von Regionalflugzeugen für die Bodenabfertigung", https://doi.org/10.7910/DVN/UMKWCI, Harvard Dataverse, V1
In dieser Arbeit werden Anforderungen für eine schnelle und kostengünstige Flugzeugabfertigung von Regionalflugzeugen mit Turbopropantrieb definiert. Die Flugzeuge sollen beispielsweise über zwei Passagiertüren verfügen, um ein schnelles Ein- und Aussteigen der Fluggäste zu ermöglichen. Die Flugzeugabfertigung soll möglichst autark von Abfertigungs... |

Camilo, Dennis, 2023, "Comparing Aircraft Wake Turbulence Categories with Induced Power Calculation", https://doi.org/10.7910/DVN/JC31A0, Harvard Dataverse, V1
Purpose – Definition of new Wake Turbulence Categories (WTC) based on the calculation of induced power of aircraft on approach. This requires the parameters aircraft mass, span, approach speed, air density, and Oswald factor (calculated from wing aspect ratio, wing sweep, wing taper ratio, winglet height, and fuselage diameter). This is considerabl... |

Rösing, Christian, 2022, "Analysis of Flight Routes and Hints for Passengers", https://doi.org/10.7910/DVN/UEJFOS, Harvard Dataverse, V1
Purpose - This project calculates Trip Emission Ecolabels (TEE) based on fuel performance, equivalent CO2, local noise level and local air pollution with NOx. As such, flight routes to different destinations (domestic, short-, middle- and long-distance) can be compared. Passengers obtain hints for selecting a flight option for minimum environmental... |
Fonseca, Diego, 2022, "Direct Operating Costs, Fuel Consumption, and Layout of the Airbus A321LR", https://doi.org/10.7910/DVN/0QHDME, Harvard Dataverse, V1
Purpose - Assessment of the Direct Operating Costs (DOC) and fuel consumption of the Airbus A321LR using typical use-cases and comparison with those from similar aircraft. Investigation of the flexibility of the cabin layout using examples from different airlines. Calculation of Ecolabels based on different cabin configurations. --- Methodology - A... |
