Problem: Develop a method to distribute liquid nitrogen from a safe zone to forest fires and overcome radiative and convective effects during delivery

Design Solution: Design of a streamlined capsule to be dropped at strategic points in the fire area, with a fin pattern to induce rotation from lift force and eject liquid nitrogen prior to contact to the ground fire

For: Senior Capstone Project


Final Deliverable Summary

Premise: the work presented below only includes work that I was involved in, but does not cover the entire extent of the capstone. The process presented below is backed up with substantial calculations that are not shown in the summary below. For a full report please contact me directly.
