The Dutch speedskating federation expressed the need for a feedback system for elite long-track speedskaters that can aid them in finding the optimal technique for an individual athlete. To contribute to this goal, this research aims to develop an optimization workflow that can reproduce realistic steady state speedskating behaviour. This is...

The Kuiper belt is one of the last mostly unexplored regions in the Solar System. Exploration of the Kuiper belt can greatly increase humanity's understanding of the Solar System's formation and evolution. The use of low-thrust propulsion for Kuiper belt missions has the potential to improve the payload mass of the mission due to the high...

Solar sailing is a flight-proven low-thrust propulsion technology with strong potential for innovative scientific missions. The heliogyro is promising sailcraft design that utilizes a set of long slender blades which are deployed and flattened by spin-induced tension and whose orientations can be individually controlled. The main advantages of...

Aviation has a negative impact on the environment. As the number of flights is expected to increase, the total environmental impact of aviation will continue to worsen. New solutions are required to mitigate these effects. Aircraft Trajectory Optimization For Environmental Impact (TOFEI) can help reduce the impact of aircraft pollutants while...

Previous trajectory proposals with the purpose of exploring the Kuiper Belt have been limited to identifying trajectories to fly by a single pre-selected Kuiper Belt Object (KBO). Furthermore, these proposals were often limited to high-velocity flybys that pass through the Kuiper Belt in a limited number of years, or are based on the assumption...

Due to recent advancements in automated driving systems, drivers are able to withdraw themselves from the control loop of the vehicle in certain driving situations. However, system limits occur relatively frequently, which results in the driver having to take back control. It is argued most currently used take-over quality quantification methods...

In order to reduce the climate impact induced by the aircraft industry, the variability between cost optimized and climate optimized flight trajectories was evaluated. This was done to establish how the climate impact reduction affects the operating costs and vice versa. To evaluate the climate impact of air traffic, a climate-chemistry model...

When sunlight illuminates a body, a tiny pressure is exerted upon its surface due to the photons impacting on it. Such a principle forms the basis of solar sailing, in which the solar radiation pressure is used to accelerate highly reflective lightweight structures called solar sails. Similarly, a laser-enhanced solar sail is a solar sail in...

Electric low-thrust propulsion has nowadays found wide application in space dynamics as it entails considerable savings in spacecraft propellant mass, thanks to the very high specific impulse that this kind of engine is able to generate. However, continuous thrust opens new extensive sets of feasible trajectories, and optimization algorithms are...

Given the current technological limitations, launch missions are extremely costly: rockets are huge, being about 100 times more massive than the payload, and most of the times expendable. The specific cost required to place a spacecraft in LEO is between 10 and 25 k€/kg. Consequently, trajectory optimization plays a major role in the design of a...

The increasing interest in solar electric propulsion techniques, that enable significant propellant mass savings for a wide class of transfers, has brought about a revolution in the approach to trajectory design and optimization, as a result of the complexity and diversity of the problem. To date, solutions of different nature exist, but...

Atmospheric entry is a process defined by extremes, from the great velocity at the point of entry to the high deceleration loads and aerodynamic heating in the lower layers of the atmosphere. In addition to the vehicle maintaining structural integrity, an equally important aspect of the re-entry mission is safety. This safety can only be...
