Engineering Design Process
Define Problem
We were asked to build a rocket that would safely return an egg (representing a human) to and from a "planet's orbit". All steps of the Engineering Design Process and daily documentation are to be recorded on the company website, as well as orthographic and isometric models of the egg contraption and rocket. We should also calculate the center of pressure of our rocket. A Hab must be built and orthographic drawing as well as resource research are to be documented. The Hab should be airtight and inflatable, and also has to be aesthetically pleasing.
