The main goal of any launch vehicle is to bring as much payload to space as possible. Space planes have been studied for decades, as they are thought to be more cost effective for frequent access to space than traditional expendable launchers. This research aims at optimizing the payload capacity of a single stage to orbit (SSTO) horizontal take...

In order to interact with environments and appliances made for humans, robots should be able to manipulate a large variety of objects and appliances in human environments. When having experience with manipulating a certain object or appliance, a robot should be able to generalize this behaviour to novel, but similar objects and appliances. When...

The role of traditional entry guidance systems is to ensure that the vehicle is brought from a nominal entry interface point (EIP) to the neighborhood of a designated landing site at an acceptable energy state. Such systems are designed in such a way that the landing site can be safely reached even if off-nominal conditions are present at the...

Trajectory optimization is an essential part of space plane mission design. One important aspect of trajectory optimization for re-entry vehicles is to minimize the total heat load at the surface when it returns and the heat flux should remain below certain limit, meanwhile, the vehicle should land at the desired point. The methods used for re...

Missions to Near-Earth Objects (NEOs) are a growing trend in spaceflight. The interest for such bodies is not only justified by the threat that they represent for the Earth, but also because they are potential sources of extra-terrestrial materials, provide windows to the past of the Solar System and to planetary formation, and offer a good...

These days more and more rockets are developed by companies, students and other amateurs. To assess the safety of these rockets, a method is necessary to estimate the risk of these vehicles quantitatively. Because tools to do so are not freely available, the goal of this thesis is to research methods to quantitatively estimate the risk of...

When a pile is driven into soil, the soil is pushed away which results in significant changes in both stress state and strain state. Using Finite Element Code to simulate the pile installation process has been not yet completely successful partly due to the limited knowledge of the governing behavior of the soil around a displacement pile. An...

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...

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...

The aviation industry has struggled with reducing the amount of noise that aircraft generate, especially when flying close to communities. This effort has led to the introduction of technological and operational novelties such as efficient trajectory planning. In line with these operational efforts, a tool has been designed in the TU Delft,...

Over the past years, numerous missions for spacecraft with low-thrust propulsion have been planned to include large orbital plane changes. In order efficiently generate and evaluate orbits for such missions, use can be made of the spherical shaping method proposed by Novak. When inclinations larger than 15 degrees are present however, the error...

The unpowered entry of a winged re-entry vehicle, such as the HORUS-2B, consists of a hypersonic atmospheric re-entry phase, a Terminal Area Energy Management (TAEM) phase and a approach and landing phase. The TAEM is the subject of this thesis study. During the TAEM, the vehicle is brought to the correct interface position with the landing...

The decision on the dynamical model used to design a spacecraft’s trajectory is a fundamental choice influenced by many factors. The complexity of such a model affects the accuracy of the designed trajectory but also the difficulty of the design process. One approach to simplify this task consists of splitting the trajectory design process into...

In a previous study, the optimal re-entry trajectory of Hyperion-2 has been derived. The mission of the vehicle is to measure hypersonic boundary-layer transition, a phenomena in which the laminar boundary layer turns into a turbulent boundary layer. This is an important feature in hypersonic flow to investigate, as it introduces peak heating...

The goal of this thesis research has been the improvement of a validated, robust low-thrust optimization tool for interplanetary trajectory design, written during the author's internship. This improved tool has then been applied to design crewed Martian flyby missions. Such a mission is a crucial step within the flexible path scenario for human...

The search for life in other celestial bodies has always been a topic of great interest within the scientific community. The curiosity to know if we are the only ones in the universe or not has driven the development of many engineering projects. This Master Thesis is meant to do its bit in this research field. Europa, a moon of Jupiter, is...

In the past few years, a new spirit for the exploration of the Solar System spread among the space community and reaching the Moon has been set as the first step of this new program. In this frame, going back to the Moon is needed to familiarize with a new way of living in a different environment, adapting to it and testing new technology. It is...

Delineating the well placement and trajectory of production or injection wells is an important step of any field development program. Drilling a well is an expensive process in terms of money, time and effort invested. Being an expensive item, wells must be carefully studied before being drilled. In order to make this process more efficient,...

In this contribution, we investigate several trajectory design methods to transfer a spacecraft to the L3 point of the Sun-Earth Circular Restricted 3-Body Problem (CR3BP). Such a study aims at performing an investigation into an area that is so far little explored: the vicinity of L3 has never been the destination of a space mission, and in...
