Formatted abstract
The shock tunnels operating at the University of Queensland all require diaphragms to initially separate the gases. During the rupturing of the diaphragms a variety of material sizes can become separated from the diaphragm and enter the gas flow reaching speeds equivalent to that of the shock. A simple solution to reduce the likelihood of large diaphragm pieces entering the shock flow is scoring the diaphragm with a cruciform extending to the shock tunnels wall.

With the redesign of the X3 shock tunnel the main stakeholder (Professor Richard Morgan) required the diaphragm pressure plate have a method of removing it from the shock tunnel section. The design stepped through several concepts that developed into the main stakeholder’s envisaged view of the requirements based around cost, time, and space. The final design produced can be made from available materials within the mechanical department’s workshop, while also being able to be manufactured inhouse.

The X2 shock tunnel requires a manual extraction of the diaphragm pressure plate which can be an inconvenient and messy method to remove this shock tunnel component. Design constraints were suggested by the main stakeholder to give a view of the desired final design. The limited room, extra complexity and the design requirement of having to lift heavy components, which the design was trying to avoid, changed the path of the design. The final design is a realistic method that will reduce the need for direct human application of force.
