The Bombardier Beetle (Carabidae, Brachinus) has a unique form of defense mechanism which involves the explosive mixing of hydroquinones and hydrogen peroxide in its internal explosion chambers and using the resultant high pressure to spray out a heated corrosive fluid containing p-benzoquinones in a controlled direction [1][2]. Three salient features of the internal explosion chambers were found to be instrumental in withstanding the high pressures generated from the explosive mixing and protecting the Bombardier Beetle's internal organs [3]. Using simulations performed with finite element analysis, it was discovered that such design features employed by the Bombardier Beetle are suitable for incorporation into helmet designs. An in-depth analysis of the market potential of such a design with respect to the motorcycle helmet market is presented along with implementation strategies and proposed business plans.
