Krull, Marlis, 2024, "Preliminary Sizing of Propeller Aircraft (Part 25)", https://doi.org/10.7910/DVN/ET4ZKV, Harvard Dataverse, V1
Purpose - This project incorporates methods for propeller efficiency estimation into a preliminary sizing tool for large aircraft certified for CS-25 respectively FAR Part 25. --- Methodology - Variable pitch propellers are considered. For them, previously collected methods for propeller efficiency estimation are evaluated and used. The resulting p... |

Hammami, Mohamed Oussama, 2023, "Turbofan Specific Fuel Consumption, Size, and Mass from Correlated Engine Parameters", https://doi.org/10.7910/DVN/UW6FAP, Harvard Dataverse, V2
Purpose – Simple equations and more extended models are developed to determine characteristic engine parameters: Specific fuel consumption (SFC), engine mass, and engine size characterized by engine length and diameter. SFC (c) is considered a linear function of speed: c = c_a * V + c_b. --- Methodology – Data from 718 engines is collected from var... |

Müller, Christian; Scholz, Dieter, 2024, "Functional Model Library of the Environmental Control Systems (FLECS)", https://doi.org/10.7910/DVN/US3KUY, Harvard Dataverse, V1
The task of the FLECS project is the development of a database for the Environmental Control System (ECS). Each component of the ECS is related to one model block. In general the description of the ECS is correlated to the description of an air/gas distribution network. The model blocks correspond to a physical model. The inner structure of the mod... |
