Anker, Thomas (author)Post-mortem interval estimation (PMI) is a key part of forensic investigation. Accurately obtaining a PMI early in the investigative process improves the reconstruction of events, directs follow-up research and narrows down suspects in case of homicide. Currently, PMI is determined using Henssge’s nomogram requiring ambient temperature, rectal...master thesis 2023

Snelders, Jeffrey (author)The aviation industry confronts challenges from increased air traffic and environmental concerns. Enhancing engine efficiency becomes crucial due to persistent greenhouse gas emissions from air travel, particularly in long flights with high CO2 emissions. Higher by-pass ratios (BPR) can address this by boosting engine propulsive efficiency, yet...master thesis 2023

Garcia Gonzalez, Pedro (author)Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...master thesis 2022

Smolders, Timothy (author)Superyachts are expected to be perfect since the owner pays millions for them, and the worst that could happen is tilting the ship once it floats. The lightweight, including the center of gravity, is essential to know with a high degree of certainty to prevent this. However, the lightweight is already expected in an early design phase, when...master thesis 2022

van der Leer, Quinty (author)The current focus in the aviation industry for more sustainable designs, could mean the revive of propeller propulsion, due to their relative high propulsion efficiency compared to jets. In addition, the application of wingtip-mounted propellers installed in tractor configuration can be used as tip-vortex attenuating devices, reducing the wing...master thesis 2021

de Ruiter, Luc (author)Unconventional aircraft designs have the potential to lower the impact of aviation on emissions and climate as compared to conventional aircraft designs. However, the flight dynamics behaviour of such unconventional configurations must be carefully evaluated by studying Stability and Control (S&C) characteristics to design safe aircraft and...master thesis 2020

Sun, Junzi (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Aircraft mass is a crucial piece of information for studies on aircraft performance, trajectory prediction, and many other topics of aircraft traffic management. However, It is a common challenge for researchers, as well as air traffic control, to access this proprietary information. Previously, several studies have proposed methods to estimate...journal article 2018

Rousseau, Rob (author)One of the novel configurations that could revolutionize the aviation industry is the PrandtlPlane. The closed-wing design features a low front wing and a high rear wing, connected by a lateral surface. In this research, the rear wings of the configuration are attached to a set of fins. Previous conceptual closed-wing design studies have failed...master thesis 2017

Zaccai, D (author), Bertels, F.G.A. (author), Vos, Roelof (author)A new methodology has been developed that integrates the preliminary wing design with trailing edge high-lift systems and accounts for three-dimensional flap kinematics. The high-lift system in the developed application includes the kinematic synthesis of four common mechanisms (dropped-hinge, four-bar, link-track and hooked-track) and a...journal article 2016

Sun, Junzi (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Aircraft mass is an important parameter in many ways, either to build aircraft performance models, to predict flight trajectories, or to simulate air traffic. Mass data is usually considered as sensitive information for airlines and is, therefore, not disclosed to researchers publicly. In this paper, we use two methods to infer the mass of an...conference paper 2016
