Van Endert, Lynn, 2022, "Definition of an Ecolabel for Aircraft", https://doi.org/10.7910/DVN/LEHDUD, Harvard Dataverse, V2
In attempting to increase the environmental awareness in the aviation sector and to eliminate the green washing phenomenon, an investigation was done into the development and definition of an ecolabel for aircraft. Based on life cycle assessment it was found that aviation affects the environment most with the impact categories resource depletion an... |
Scholz, Dieter, 2020, "Calculation of the Emission Characteristics of Aircraft Kerosene and Hydrogen Propulsion", https://doi.org/10.7910/DVN/DLJUUK, Harvard Dataverse, V4
Calculation of the emission characteristics of aircraft kerosene and hydrogen propulsion have been done in comparison. The method from SCHWARTZ 2009 was applied and adapted. Hydrogen combustion is free of CO2 emissions, but has 2.58 times more water emissions. This primary effect would lead to an equivalent CO2 mass 50% higher than for kerosene. Ho... |

Láinez Muñiz, Alfonso, 2021, "The Cubic Wing Loading Parameter in Passenger Aircraft Preliminary Sizing", https://doi.org/10.7910/DVN/HELNOX, Harvard Dataverse, V1, UNF:6:jdA6LRhPnaYWc6F2Il43CQ== [fileUNF]
Purpose - This thesis investigates the parameter Cubic Wing Loading (CWL). It is the mass of the aircraft divided by the wing surface area taken to the power of 3/2. As such the unit of the denominator is converted from m² to m³ and CWL has the unit of kg/m³. Classical Wing Loading (WL) is aircraft mass divided by wing area. It is investigated, if... |

Mariën, Floris, 2021, "Software Testing: VSPAERO", https://doi.org/10.7910/DVN/0S1R14, Harvard Dataverse, V1, UNF:6:hULMSzeOWQZiMFzgiKZxyA== [fileUNF]
Purpose - Test the aerodynamic analysis code VSPAERO, which is part of OpenVSP from NASA. Apply VSPAERO to calculate the lift curve slope and the span efficiency factor of straight wings (for various aspect and taper ratios) as well as the induced drag of box wings (for various h/b-ratios) relative to their reference wing. --- Methodology - VSPAERO... |

Scholz, Dieter, 2021, "Equivalent CO2 from Various Sources in EU27 1990 to 2017 and Linear Projection to 2030", https://doi.org/10.7910/DVN/QFNRYQ, Harvard Dataverse, V1
GHG emissions decreased in the majority of sectors in the EU between 1990 and 2017, with the exception of transport and especially aviation. The largest decrease in emissions in absolute terms occurred in energy supply and industry, although agriculture, residential and commercial (i.e. buildings), and waste management have all contributed to the p... |

Burzlaff, Marcus, 2017, "Aircraft Fuel Consumption – Estimation and Visualization", https://doi.org/10.7910/DVN/2HMEHB, Harvard Dataverse, V2
In order to uncover the best kept secret in today’s commercial aviation, this project deals with the calculation of fuel consumption of aircraft. With only the reference of the aircraft manufacturer’s information, given within the airport planning documents, a method is established that allows to computing values for the fuel consumption of every a... |

Scholz, Dieter, 2021, "Energy Consumption, CO2, and Equivalent CO2 – Aircraft versus Train", https://doi.org/10.7910/DVN/QFG2SD, Harvard Dataverse, V1
Aircraft are far away from zero emission and have no chance to reach the environmental friendliness level of trains. Their burden to the environment is a factor between 2.8 and 49 higher than the environmental burden of trains per passenger and kilometer. It depends what metric is applied: energy consumption, CO2, or equivalent CO2. Sustainable Avi... |

Krammer, Philip, 2021, "Integration of a Noise Analysis Module into a Multidisciplinary Aircraft Design Process", https://doi.org/10.7910/DVN/OAQNZL, Harvard Dataverse, V1
Eine Reduzierung des Fluglärms kann sowohl durch Änderung primärer Lärmquellen am Flugzeug selbst, als auch durch Anpassung relevanter Flugzeugentwurfs- und Flugleistungsparameter erreicht werden. Eine getrennte Betrachtung beider Ansätze muss nicht unmittelbar zu dem gewünschten Ergebnis führen. Eine methodische Herangehensweise ist daher unumgäng... |

McDavid, Jascha; Kühner, Benjamin, 2021, "Empennage Sizing: The Tail Lever Arm as a Percentage of Fuselage Length Determined from Statistics", https://doi.org/10.7910/DVN/TLFDIU, Harvard Dataverse, V1
This project gives an overview of a selection of geometrical parameters with respect to the tail volume coefficient. A statistic on the basis of 30 aircraft, which differ in their dimensions, was made. One target was to create a graphical method for finding the tail levers arms, both for the horizontal, and the vertical tail. The average tail lever... |

Gmelin, Philipp, 2021, "Requirements from National Regulations for Microlight Aircraft and Statistical Parameters for Preliminary Sizing", https://doi.org/10.7910/DVN/NKTCX1, Harvard Dataverse, V1, UNF:6:6rLNFZ4iIbdoTijJwE7KYw== [fileUNF]
The purpose of this project is to examine and describe the regulations of microlight aircraft. The national rules of mostly European countries are described in more detail and are compared to the German rules. Most important among the regulations is the maximum take-off mass. In some countries, the limit of 472.5 kg has been raised recently to 600... |
