L'Ortije, Jasper (author)With a booming eVTOL market, many new companies will design their own vision of the future of urban transport. Therefore, a MATLAB flight dynamics model is needed to accurately design a Lift + Cruise Aircraft in the preliminary design phase. The MATLAB program is based on the EVE V3 aircraft by Embraer. The model successfully simulates an input...master thesis 2023

Tzanetos Alevras, Tzortzis (author)This research presents a comprehensive modeling approach for the flight dynamics of a hybrid compound helicopter, employing classical mechanics methods. The derived non-linear mathematical model encompasses the individual components of the aircraft, including the rotor, propellers, wings, fuselage, and empennage, which are then integrated into a...master thesis 2023

Maurer, Maarten (author)Control of a helicopter with a deployed dipping sound navigation and ranging (SONAR) is no trivial task due to the complex dynamics of the suspension cable. The cable can change shape, which influences the effect of water, wind and the motion of the helicopter itself. To control such a system, a control method is needed that can cope with these...master thesis 2023

van Teeffelen, Jop (author)The demand for online shopping has grown tremendously in the last couple of years. Picnic, a major player in the online grocery industry, is struggling to achieve long-term growth within its current operations. Scheduling and planning are key drivers for maintaining operational efficiency. The Fulfilment Centre (FC) and...master thesis 2022

Sokołowski, Piotr (author)State-of-the-art tilt-rotor flight mechanics models appear to be inadequate in predicting the flight dynamics behavior across the entire flight envelope due to a lack of experimental data suggesting the need for more generic models. This paper presents a middle ground between model flexibility (genericity) and accuracy. For this purpose a...master thesis 2022

Sîrghi, Florina (author)The interest in developing electric vertical takeoff and landing (eVTOL) vehicles has increased sharply in recent years. A concern for passenger acceptance of the new type of vehicle is that people may experience motion sickness. This is because eVTOL flight profiles are different from the motion conditions that people have previously...master thesis 2022

Krook, Ralph (author)Incremental nonlinear control is a promising control method that can be applied in controlling tasks that involve systems with highly nonlinear dynamics. Incremental nonlinear control is a feedback linearization method that requires less model knowledge than conventional Nonlinear Dynamic Inversion and is robust against model mismatches. This...master thesis 2022

den Ouden, Wessel (author)Due to their highly coupled and non-linear behavior, helicopters seem excellent subjects to apply non-linear control theory to. Furthermore, the rotor is operating in its own wake, leading to complex aerodynamics. A Command Filtered Incremental Backstepping controller has been applied to a simulation model of an MBB Bo-105 hingeless rotorcraft....master thesis 2022

Feng, Haoyu (author)A tiltrotor has the features of both a fixed-wing aircraft and a helicopter, thereby blending the vertical flight capabilities of helicopters with the speed, altitude, and range of fixed-wing aircraft. However, as an important aspect of piloted aircraft, the handling qualities of tiltrotor aircraft have not been studied extensively. This thesis...master thesis 2021

Wellens, Lotte (author)Model predictive control is an optimal, model-based control method that has the powerful capability of directly including input and output constraints. Next to this, it is known that helicopters are hard to fly with its complex, unstable and highly coupled dynamics. With the introduction of the concept of handling qualities, guidelines for...master thesis 2021

Kaihatu, Emile (author)A new market of Urban Air Mobility (UAM) vehicles is emerging and ride quality may be considered as one of the key factors to insure a successful introduction. In the scope of this thesis, a framework was developed to evaluate ride quality with respect to UAM vehicles. The framework includes modules for ride quality assessment, seat transfer and...master thesis 2020

Yip, Bryan (author)Nowadays the origins and solutions for rotor-induced vibrations in helicopters are well-known. However, non-rotor induced low-frequency vibrations still remain a topic of research, although it has proven that these tend to become a dominant source of pilot discomfort, especially in case of turbulence. Therefore, this research aims to come to a...master thesis 2018

Thijs, R.J. (author)This thesis describes the process of creating numerical derived stability analysis of an Chinook with underslung loads. A helicopter model with underslung loads is build and numerically linearized. After the linearization the eigenvalues are calculated and plotted. It was found that numerical linearization works well with a single solid body,...master thesis 2016

Janssen, M. (author)This thesis was conducted at KVE Composites Group (The Hague, The Netherlands). The aim of this thesis is to create an aeroelastic model that can be used during the design phase of these rotor blade projects. An aeroelastic was created consisting of a Ritz-Hamilton structural model, a lifting line quasi steady aerodynamic model with two inflow...master thesis 2015
