Menkhorst, Mike (author)Drones are becoming an ever increasing part of our lives. From airshows to surveillance systems, their use varies greatly and, as technology improves, this variety will continue to increase. As drones get smaller, new applications arise. For example, drones for monitoring crops or searching for survivors in hard to reach places in disaster areas...master thesis 2023

Moens, Tieme (author)Flying drones have been a well-established field of engineering for many years now. With the wave of bio-inspired design came the idea of flapping wing micro air vehicles (FWMAVs). These drones use flapping wings instead of fixed or rotary wings to generate their lift, giving them the potential for agile movement and application in confined...master thesis 2023

Wang, Chenyao (author)Flapping wing micro aerial vehicles (FWMAVs) are known for their flight agility and maneuverability. However, their in-gust flight performance and stability is still inferior to their biological counterparts. To this end, a simplified in-gust dynamic model, which could capture the main gust effects on FWMAVs, has been identified with real in...master thesis 2022

Wang, C. (author), Wang, S. (author), de Croon, G.C.H.E. (author), Hamaza, S. (author)Flapping wing micro aerial vehicles (FWMAVs) are known for their flight agility and maneuverability. These bio-inspired and lightweight flying robots still present limitations in their ability to fly in direct wind and gusts, as their stability is severely compromised in contrast with their biological counterparts. To this end, this work aims at...journal article 2022

Roulaux, Bas (author)Flapping-Wing Air Vehicles (FWAV) are autonomously flying vehicles that use their flapping wings to simultaneously stay aloft and enable controllable flight. FWAVs that are capable of controllable flight are reported in literature, though a theoretical background of the aerodynamic performance of different attitude control mechanisms is absent...master thesis 2021

Kelbling, Jelle (author)The DelFly Nimble is a type of tailless flapping-wing micro air vehicles (FWMAVs) that has received an increasing amount of attention. FWMAVs show efficient and agile flight possibilities at small scale. The aerodynamics and dynamics of these flapping vehicles are challenging and not fully understood. In this work, a strategy to implement a 3D...master thesis 2020

Ras, Meindert (author)The Atalanta is a palm-sized, insect-inspired, flapping-wing micro air vehicle developed by the University of Technology Delft. In its current form, the Atalanta has a lift-to-mass ratio of 0.12 which inhibits it from taking off. Getting the Atalanta to fly would greatly benefit the research into areas such as aerodynamic modelling, on-board...master thesis 2020

Heitzig, D. N.W.M. (author), van Oudheusden, B.W. (author), Olejnik, D.A. (author), Karasek, M. (author)This study investigates the wing deformation of the DelFly II in forward flight conditions. A measurement setup was developed that maintains adequate viewing axes of the flapping wings for all pitch angles. Recordings of a high-speed camera pair were processed using a point tracking algorithm, allowing 136 points per wing to be measured...journal article 2020

Narayanan, Anirudh (author)The goal of this study is to understand the processes and wing characteristics that influence lift generation of a flapping wing, and apply the acquired knowledge in an optimization setting to obtain an optimal wing thickness distribution which maximizes effective wing lift. To achieve this, an extensive literature survey was conducted to...master thesis 2019

Heitzig, Dorian (author)This study investigates the wing deformation of the flapping-wing micro air vehicle (MAV) DelFly II in various flight configurations. Experiments were carried out with the MAV tethered in a windtunnel test section. To determine the best suited measurement approach, a trade-off study was carried out which showed that a point tracking approach...master thesis 2019

Armanini, S.F. (author), Caetano, J. V. (author), de Visser, C.C. (author), Pavel, M.D. (author), de Croon, G.C.H.E. (author), Mulder, Max (author)Despite significant interest in tailless flapping-wing micro aerial vehicle designs, tailed configurations are often favoured, as they offer many benefits, such as static stability and a simpler control strategy, separating wing and tail control. However, the tail aerodynamics are highly complex due to the interaction between the unsteady...journal article 2019

Risseeuw, Derek (author)Flapping wings display complex flows which can be used to generate large lift forces. Flexibility in wings is widely used by natural flyers to increase the aerodynamic performance. The influence of wing flexibility on the flow can be computed using numerical analysis with Fluid Structure Interaction (FSI). However, there is a lack of open-source...master thesis 2019
