After the space race to the Moon, Mars has been chosen the new destination to be explored by mankind. Cryogenic propellant is necessary to make space beyond the Moon accessible. Boil-off of cryogenic liquids raises the initial mass of spacecraft by increasing the amount of propellant required to carry-on. Therefore, mitigation of boil-off is key...

Recent years have seen a drastic increase in the number of small satellites launched per year, as these systems weighing less than 1000 kg have become less expensive alternatives to obtaining scientific data compared to satellites weighing multiple tons. A current drawback with these systems is their price to orbit, often reaching over $100k ...

Reusable rocket stages is a trend in launch vehicles that have been observed for some time now. Even reusable upper stages have been seen in the Space Shuttle, Kistler K-1 and now the SpaceX Starship. This thesis is on the development of a genetic optimisation algorithm to determine the economic feasibility of upper stage reusability. Genetic...

The conducted study investigates the potential of a newly released multi-phase solver to simulate atomization in liquid rocket injectors. The "VOF-to-DPM" solver was used to simulate primary and secondary atomization in an air-blast atomizer with a coaxial injector-like geometry. The solver uses a hybrid Eulerian/Eulerian-Lagrangian formulation...

KNO3-Sugar propellants, also known as rocket candy, form a group of simple, cheap and safe solid propellants that are used extensively in student and amateur rocketry communities. One of the most frequently used compositions is KNO3-sorbitol (KNSB) with a typical 65/35 ratio by mass. This composition is used extensively by Delft Aerospace Rocket...

During the launching vehicles design and their optimization process, the implementing of aerodynamic characteristics (AC) database is quite important. Accuracy of such database determines quality of the pre-flight simulation, trajectory and even the whole design direction. However, the database building process is one of the most challenging...

Flow over smooth surfaces has been studied ever since the start of aerodynamic research. Non-smooth irregularities in rough walled surfaces will impact on the flow and induce changes in friction and heat transfer. The term 'rough walled' encompasses a range of shapes, ranging from material roughness to wall profiles with heights up to the...
