Bruggeman, A.M.R.M. (author), Nikitin, M. (author), la Rocca, G. (author), Bergsma, O.K. (author)During the early design stages of airframe components, many possible design architectures and production methods need to be traded to find the best configuration. Evaluating different production methods can be challenging as different production methods put different requirements on the product to be designed. This paper presents a new...conference paper 2024

Li, H. (author), Ribeiro, M.J. (author), Santos, Bruno F. (author), Tseremoglou, I. (author)Aircraft maintenance scheduling is a focus point for airlines. Maintenance is essential to ensure the airworthiness of aircraft, but it comes at the cost of rendering them unavailable for operations. In current operations, aircraft maintenance scheduling must often be updated to include time for non-routine and non-schedule tasks. These non...conference paper 2024

Başkaya, A.O. (author), Hickel, S. (author), Dungan, Sean (author), Brehm, Christoph (author)Direct numerical simulations (DNS) are performed over 15° compression ramp undergoing ablation at Mach 8 to examine fluid-ablation interactions (FAI) on transitional high-speed boundary layers. The experiments at these conditions with a rigid wall are first numerically replicated for a laminar flow. Heating streaks are introduced by perturbing...conference paper 2024

van Campen, J.M.J.F. (author)In 2022 Airbus and Boeing combined delivered 1203 commercial aircraft. With an annual predicted growth of 4.3% for the coming 20 years there is an urgent need for end of life solutions that go beyond down-cycling of parts that cannot be reused. Especially carbon fibre reinforced composites are hard to recycle, and attempts to deliver recyclable...conference paper 2024

de Vries, R. (author), Wolleswinkel, Rob E. (author), Hoogreef, M.F.M. (author), Vos, Roelof (author)Battery-electric aviation is commonly believed to be limited to small aircraft and is therefore expected have a negligible impact on the decarbonization of the aviation sector. In this paper we argue that, with the correct choice of design parameters and top-level aircraft requirements, the addressable market is actually substantial. To...conference paper 2024

Wolleswinkel, Rob E. (author), de Vries, R. (author), Hoogreef, M.F.M. (author), Vos, Roelof (author)Thus far, battery-electric propulsion has not been considered a promising pathway to climate-neutral aviation. Given current and expected battery technology, in most literature battery-electric aircraft are only considered feasible for short ranges (< 400 km) and small payloads (< 19 pax). As a result, battery-electric aircraft development...conference paper 2024

Joksimović, Aleksandar (author), Carbonneau, Xavier (author), Brazier, F.M. (author), Vingerhoeds, Rob (author)This paper presents a simple explanatory framework to analyse the diverse strategies proposed by the civil aviation sector in attempts to reconcile its growth tendencies with its impact on natural environment. Despite framing the industry as a single entity that has a problem to solve, it is better represented as a diverse set of actors, each...conference paper 2024

Joksimović, Aleksandar (author), Brazier, F.M. (author), Carbonneau, Xavier (author), Vingerhoeds, Rob (author)An overwhelming abundance of innovative civil aeroplane concepts has been presented by the research community in recent decades. Their development has been motivated mainly by need for better operating energy, or in particular the fuel efficiency - the common objective variable for economic and environmental optimisation. This paper focuses on...conference paper 2024

Joksimović, Aleksandar (author), Carbonneau, Xavier (author), Brazier, F.M. (author), Vingerhoeds, Rob (author)This paper presents development of an innovative method for aeroplane system architecture design, based on the principles of causal networks. In light of the environmental crisis that the world faces, it is argued that the new design method should be motivated by sustainability values in the first place. This implies the necessity for a method...conference paper 2024

Velázquez Navarro, Ester (author), Solano-López, Pablo (author), Uriol Balbin, I. (author)The demand for pressurized, large structures in space, such as habitats or fuel deposits, is increasing as the space industry grows. The limited payload volume of launch vehicles, combined with their highly constrained shape, presents a significant challenge for these structures. Origami-inspired deployable structures have emerged as a potential...conference paper 2024

Rotundo, C.D. (author), Sinnige, T. (author), Sodja, J. (author)A tightly coupled aeroelastic design code for composite propeller blades was developed, verified, and used to perform design sensitivity studies. The design code features a structural model that accounts for geometric nonlinearities through the application of a corotational framework, nonlinear responses to loads, and a cross-sectional modelling...conference paper 2024

Çavdar, I. (author), Mooij, E. (author)Within the last decade, the use of launch vehicles has increased as private companies have emerged in the space exploration industry. Compared to the early 1980s, the market for launch vehicles has become significantly more competitive, introducing the desire to have fully reusable launch vehicles. The true benefits of fully reusable launch...conference paper 2024

Mooij, E. (author), Root, B.C. (author)With the increasing interest in the Solar System's smaller bodies, quite a few missions have been sent to comets and asteroids, and more will be send in the near future.
