Jakimovska, N. (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)An improved understanding of pilot’s control behavior adaptations in response to sudden changes in the vehicle dynamics is essential for realizing adaptive support systems that remain effective when task characteristics suddenly change. In this paper, we replicate, extend, and validate the ‘adaptive pilot model’ proposed by Hess to verify its...conference paper 2023

van Overeem, S. (author), Wang, Xuerui (author), van Kampen, E. (author)Considerable growth in the number of passengers and cargo transported by air is predicted. Moreover, aircraft noise and climate impact become increasingly important factors in aircraft design. These existing challenges in aviation boost interest in the design of innovative aircraft configurations. One of these configurations is a V-shaped flying...conference paper 2023

Vasilopoulos, V.G. (author), Borst, C. (author), van Paassen, M.M. (author), in 't Veld, A.C. (author), Mulder, Max (author)The Continuous Descent Approach (CDA) offers reduced aircraft noise emissions and fuel consumption, but the obstacle limiting it to reduced traffic density conditions, is the low predictability of the trajectory and Estimated Time of Arrival (ETA). The solution proposed by this research is to develop a pilot support interface to facilitate the...conference paper 2023

Vugts, G. (author), Stroosma, O. (author), Vos, Roelof (author), Mulder, Max (author)A novel aircraft configuration, the tailless Flying-V, is examined for its longitudinal handling qualities in cruise by means of piloted simulations. The Flying-V is controlled by two aileron/elevator (elevon) surfaces on each side, and rudders on each wingtip. Two control allocation schemes were created: a conventional one where both inboard...conference paper 2023

Mooij, E. (author), Wang, Xuerui (author)This paper focuses on the attitude control and propellant slosh suppression of aeroelastic launch vehicles in a turbulent atmosphere. For a five-degree pitch-angle block command, the tracking performance of the selected Incremental Non-Linear Dynamic Inversion Sliding Mode Controller (INDI-SMC) shows excellent tracking performance. However,...conference paper 2023

Völker, W.J.E. (author), Li, Y. (author), van Kampen, E. (author)Recent research on the Flying V - a flying-wing long-range passenger aircraft - shows that its airframe design is 25% more aerodynamically efficient than a conventional tube-and-wing airframe. The Flying V is therefore a promising contribution towards reduction in climate impact of long-haul flights. However, some design aspects of the Flying V...conference paper 2023

Vasudevan, S. (author), De Breuker, R. (author), Wang, Xuerui (author)This paper aims to explore the advantages offered by machine learning (ML) for dimensionality reduction of nonlinear transonic aerodynamics. Three ML techniques are evaluated in terms of their ability to generate interpretable low-dimensional manifolds of the transient pressure distributions over a NACA4412 airfoil equipped with a flap. These ML...conference paper 2023

de Haro Pizarroso, Gabriel (author), van Kampen, E. (author)Reinforcement Learning is being increasingly applied to flight control tasks, with the objective of developing truly autonomous flying vehicles able to traverse highly variable environments and adapt to unknown situations or possible failures. However, the development of these increasingly complex models and algorithms further reduces our...conference paper 2023

de Boer, S. (author), Karpel, M. (author), Sodja, J. (author)A new flutter test version of the Parametric Flutter Margin (PFM) method, specifically applied to wings undergoing large deflections is presented. The PFM method adds a stabilising parameter, such as a stabilising mass, to the model such that the flutter velocity is increased. By exciting the stabilising mass in one of the primary (i.e., x, y...conference paper 2023

Pollack, T.S.C. (author), van Kampen, E. (author)This paper proposes an extension to the traditional flight path reconstruction filter to simultaneously reconstruct the aircraft rigid body states together with modal amplitudes and velocities of the structure. To achieve this, the filter makes use of additional accelerometers, gyroscopes and strain gauges placed across the aircraft structure....conference paper 2023

Mooij, E. (author)To limit the mass of the vehicle's thermal protection system, an optimal trajectory that minimises the total integrated heat load should be flown. This means that the maximum heat-flux constraint is followed for as long as possible, until the maximum mechanical load is encountered. Flying as close to this load as possible contributes to...conference paper 2023
