Kühn, Marius, 2024, "Fuel Consumption of the 50 Most Used Passenger Aircraft", https://doi.org/10.7910/DVN/4CYNKA, Harvard Dataverse, V3
Purpose - Fuel consumption of passenger aircraft is certainly known, but towards the public it is considered an industry secret. This project defines fuel consumption for passenger aircraft, shows and evaluates methods and databases for its calculation, and lists the fuel consumption of the 50 most-used passenger aircraft. Input data is only from p... |
Sarmiento Beltran, Danny Steeven, 2024, "From CAS to EAS – Calculating and Plotting the Compressibility Correction Chart", https://doi.org/10.7910/DVN/6QWEX1, Harvard Dataverse, V1
Purpose – The conversion between calibrated airspeed (CAS) and equivalent airspeed (EAS) is relatively cumbersome, because it involves the calculation of incompressible flow, for which the equations are quite long. If calculations on the computer are required, conversions with equations are necessary. In contrast, this project calculates a CAS to E... |
Hirsch, Sebastian, 2024, "The 50 Most Important Parameters of the 60 Most Used Passenger Aircraft", https://doi.org/10.7910/DVN/YAHODP, Harvard Dataverse, V1
Purpose – This project creates a database of more than 60 passenger aircraft types, which are most in use (based on in-service data from 2020). The aircraft are characterized by the most important 50 parameters. --- Methodology – Almost all parameters were retrieved from manufacturer's documents for airport and maintenance planning as well as from... |

Rösing, Christian, 2023, "Design of a Hydrogen Fuel Cell Powered Long-Endurance Drone for Wildfire Detection", https://doi.org/10.7910/DVN/JKKX2M, Harvard Dataverse, V1
Purpose – In this bachelor thesis, a drone is developed that will be used for early wildfire detection. The drone should also be able to be used by authorities to detect oil spills or to provide live images in the event of disasters and large-scale emergency operations. In order to keep noise and environmental pollution in the area of operation as... |

Bayón Fernández, Maruxa, 2023, "CFD Tool VSPAERO: Actuator Disk and Flow Visualization", https://doi.org/10.7910/DVN/HFCSQZ, Harvard Dataverse, V1, UNF:6:pkoaACaGMNMVg+N7mYhgfg== [fileUNF]
Purpose – To show how VSPAERO as part of OpenVSP from NASA can be set up to visualize and analyze the flow around passenger aircraft lifting surfaces combined with jet engines. The actuator disk inside a duct is used to model this aero-propulsive interaction. --- Methodology – Aerodynamic results obtained with VSPAERO for wing and tail are compared... |

Albrecht, Tobias, 2023, "Design of a Modern Passenger Aircraft with Diesel-Engine and Propeller", https://doi.org/10.7910/DVN/VQCSCF, Harvard Dataverse, V1
Purpose - This project investigates the economic viability of a large diesel-powered passenger aircraft based on the Airbus A320-200 Top Level Aircraft Requirements (TLAR) and its possible contribution to reducing CO2 emissions. --- Methodology - A redesign of the A320-200 is used as reference aircraft. In a second step, a turboprop aircraft that m... |

Putri, Dinda Andiani, 2023, "Comparing Modes of Transportation with an Improved Kármán-Gabrielli Diagram", https://doi.org/10.7910/DVN/INTM5L, Harvard Dataverse, V2
Purpose – To find, how passengers and freight transport efficiency depends on vehicle cruise speed. Based on the Karman-Gabrielli Diagram, four new diagrams are investigated. Plotted is a) the lift-to-drag ratio (weight-to-drag ratio) versus cruise speed. b) Vehicle weight is replaced by the weight of the payload. c) Plotted is the inverse of energ... |
