Abstract

This dissertation entails the design of a pneumatic clamp for the USQ optical access engine. A literature review on Optical engines and the relevant theory was conducted. During the design work, consideration of feasibility was critical to ensuring that the operation of the clamp would be sound, based on the current engine design by Kevin Dray. The focus of the design work involved identification and segregation of the components into different areas of analysis. The main components were analysed and the results for these subsections have been presented in this dissertation.

3D modelling software was utilized to assist in the design process. Tools on this software provided insight into the response of different components when place under certain loading and thermal conditions. It was found that the use of a standard 150 psi air compressor would indeed be sufficient to supply the pressure required to seal the combustion chamber during engine operation. The controlling element for the system was a proportional valve. The dynamics of the system based on valve positon have been described. The true valve response was neglected in the analysis as they typically responding almost instantaneously.

The final results suggested that the stresses involved would be deemed safe. In particular, the O-ring appeared to indicate no extrusion and the optical ring, while indicating some considerably high stress areas, would still be deemed safe if constructed from a material such as Sapphire. Overall, the system proved to be feasible, based on the results obtained. Recommendations for further work have been given.
