Voß, Nico (author)Quad-planes combine hovering and vertical takeoff and landing capability with fast and efficient forward flight. Regular Quad-planes with dedicated pusher motor can be subject to gust disturbances, and are not well-equipped to deal with actuator faults. Dual-axis Tilt-Rotor quad-planes are more maneuverable due to their overactuation. This also...master thesis 2024

Piera, Hielke (author)A decades-long steady rise in air movements has disproportionally impacted airport-neighbouring communities. These communities bear the brunt of the aviation industry's air, and noise pollution, detrimental to their livelihood. Airports near densely populated areas face increasing societal and governmental scrutiny to reduce their noise...master thesis 2024

van Putten, Noël (author)In this paper, the Proximal Policy Optimization (PPO) algorithm is used to perform a constrained wing shape optimization. The PPO algorithm is a Machine Learning (ML) algorithm that improves itself by repeatedly performing the same optimization and learning from its results. The complete adaptation of the PPO framework to the design problem is...master thesis 2024

Kukkola, Max (author)Heterogeneous materials are vital for both the modern engineer and inquisitive scientist alike. They make up a vital material class that can either form inevitably as a result of material processing (such as crystallization in metals) or can be intentionally designed for to gain desirable properties (such as anisotropy in composites). As such,...master thesis 2024
