Innovation in water rockets development based on biomimicry design tool in collaboration with the Aerospace Engineering Group of Universidad de Costa Rica (UCR)

Abstract

At Universidad de Costa Rica (UCR), we are bringing solutions and approaches to aerospace engineering in a more holistic way, considering other factors in addition to the traditionally technical ones. Since Costa Rica is a rich country in terms of biodiversity per area, we have ventured into the use of biomimicry approaches to achieve innovative and different solutions to rocketry problems. As a starting point, in this line of research and development, optimization through biomimicry thinking of the landing systems of high-power rockets was our topic of interest. This design approach from and with nature led us to propose as sources of inspiration and adaptations of robust functionality, the flying seeds of the South Pacific of Costa Rica. A prototype of a parachute system for a water rocket has been built; its design was based on the seeds of the Cedro Amargo, Cedrela odorata tree. The most remarkable characteristics of interest of this seed are the geometrical configurations and aerodynamic features, which we have identified as compatible with rocket parachute systems. This approach has allowed the development of tools for interdisciplinary collaboration, design analysis, use of materials, and experimentation that go beyond traditional practices. The biomimicry tool, in a country with significant natural wealth, represents a differentiating aspect of new design ethics, a driver of development and innovation and positions the University of Costa Rica and the country as a benchmark in the systematisation of comprehensive interdisciplinary methodologies that foster active involvement and deep respect for the natural world. In this scientific paper, we will describe the process that led to the definition of crucial variables, the selection of the best sources of inspiration from nature, and the impactful aspects that were considered in the final design. This research is the result of the project C1461 Mobile Laboratory of Action and Thought in Biomimetic Arts supported by the UCR.
