Hypervelocity Impact Simulation using Smoothed-Particle Hydrodynamics

The issue of space debris in Low Earth Orbit is a growing concern that requires comprehensive solutions. This includes preventing further pollution, removing existing debris, and designing resilient spacecraft that can withstand impacts. This thesis focuses on the improvement of spacecraft shielding structures to provide effective protection...

Momentum Transfer due to Hypervelocity Impacts into Spacecraft Solar Arrays

Spacecraft are under constant threat from hypervelocity impacts by micrometeoroids and space debris. Due to their large surface area and hence increased probability of being impacted by debris, solar arrays are of particular concern. For larger, trackable debris objects, collision avoidance manoeuvres can be performed so as the minimise the...

Hypervelocity impact and outgassing tests on ethylene-co-methacrylic acid ionomers for space applications

The ability of a material to self-repair is particularly important in remote or hostile environment applications, where an external intervention is nearly impossible. For example, the development of self-healing (SH) materials for space applications could dramatically improve spacecraft performances and liability, with significant enhancement of...

Mitigating the effects of space debris on composite structures embedding self healing and carbon nanotube nanocomposite materials

The presence in space of micrometeoroids and orbital debris, particularly in the lower earth orbit, presents a continuous hazard to orbiting satellites, spacecrafts and the international space station. Space debris includes all non-functional, man-made objects and fragments. As the population of debris continues to grow, the probability of...
