Abstract

The goal of this project was to create a system in which a cylindrical body is expelled from an outer tube by means of explosion or implosion. The system uses the implosion as a trigger for the expulsion of the cylindrical body without the use of a power source as the use of the system designed in this project is in case of power loss or failure. The cylindrical body is to be of neutral buoyancy, and it is to be cleared out of the outer tube entirely. These objectives were achieved in this design process. The trigger used in this design is entirely mechanical as it comes from the use of an implodable cylinder, designed to withstand pressures up to a certain range. Through research, a formula needed to calculate the allowable pressure to buckle a thin simple cylinder was found. This formula was used to optimize the dimensions of the implodable cylinder and to ensure its range of allowable pressures. Through the use of springs and potential energy, a system was designed to use the implosion of the implodable cylinder to trigger a series of force reactions that will in turn use the spring forces to fully expel the cylindrical body from the outer tube. This final design that has been created is a result of over 120 different design concepts that have converged and stemmed from each other. In depth analysis of components through Abaqus models, SolidWorks drawings, testing, and other calculations have allowed this concept design to develop into the design that has been finalized in this report.
