The dynamic measurement of physical parameters in an explosively driven system is a difficult and often complex problem. With explosive systems reaching temperatures of 1000’s of degrees, pressures measured in GPa and velocities of several km/s, it is an extreme environment in which to make high precision measurements.
An important aspect of determining the optimum composition of a given fuel in an explosively driven system is the ability to measure the dynamics of the very rapid reaction. Optical fibres and fibre Bragg gratings have proven a reliable way of determining the detonation velocity of such fuel with very high precision, but so far extracting precise information about the underlying dynamics of the processes have proven elusive mostly because of a lack of sensor technologies capable of measuring the information. Fast, optical interrogation combined with novel fibre designs is likely to help provide this information and the aim of this project is to design and test an instrument which will provide accurate dynamic displacement data.
The project conducted in collaboration with colleagues at AWE will be of a mainly experimental nature but some theoretical modelling and design is required to support and plan for the experimental work. The project offers considerable opportunities for students who show strong innovation as well as a desire to broach new areas of science and technology.
