Overview
The materials under consideration in this experimental research project are solid rocket motor propellants. The overall objective of the project is to assess the cumulative physical effects that routine operations have on their safety and operational performance, throughout their intended lifetimes.
For example, aerospace systems and components which are subject to long periods of low amplitude vibration can be susceptible to damage. Within composite systems such as propellants, damage can accumulate in the form of constituent debonding, crack network and cavity formation. Further factors which are known to induce and influence damage severity are material ageing and degradation, and the occurrence of low velocity impacts.
The research project will study the process of damage evolution, whatever its cause, and will quantify its effect on system performance. Understanding the changes in combustion behaviour and thermo-mechanical properties are the main drivers; features such as polymer degradation, void formation, and flame propagation need to be quantitatively assessed.
Responsibility
The successful student will join the Fracture and Shock Physics Group at the Cavendish Laboratory. The group has an international reputation in the area of shock physics, explosives characterisation and high-speed diagnostics.
Studentship Value
This project is supported by QinetiQ, and due to funding restrictions, only candidates from the UK or EU are eligible for full support, with the current tax-free maintenance stipend being up to 13,290 per year.
Applicants should hold a First or Upper-Second degree in physics, chemistry, engineering, material science or a related subject, and in addition an aptitude for experimental work is essential.
Start Date: 1 January 2010.
Enquiries to Dr. D. M. Williamson, dmw28@cam.ac.uk Research Group Website - http://www-pcs.phy.cam.ac.uk/fsp
Application deadline: 12 December 2009
