'''Daedalus''' is an SSI program to teach design principles of high power rocketry with hands-on experience. Teams will design and launch novel rocket concepts iteratively, starting with L1, L2 and finally ending with an L3 rocket that successfully flies the thoroughly tested design. The technology coming out of this project will benefit the Rockets Team’s flagship rocketry project.<br />

# The rocket will be certified through [https://en.wikipedia.org/wiki/Tripoli_Rocketry_Association Tripoli Rocketry Association] or the [https://en.wikipedia.org/wiki/National_Association_of_Rocketry National Association of Rocketry]

 

 

 

Each team will undertake the long process and end up with an L3 built from scratch. Documentation of the process is a crucial aspect of Daedalus. Explaining pitfalls, triumphs, and the minutiae of designing a fully functional rocket will aid and speed up the process for future teams. Each team will go through a five stage development cycle: 1. research, 2. preliminary design, 3. design, 4. testing and documentation review, 5. build and launch. The milestones will focus on providing hardware - not presentations.<br />

After many hours of thought, the team decided on the name Daedalus. The justification can be understood from reading this highly relevant wikipedia quote: “Daedalus was a skilled craftsman and artist... Daedalus set to work to fabricate wings for himself and his young son Icarus. He tied feathers together, from smallest to largest so as to form an increasing surface. He secured the feathers at their midpoints with string and at their bases with wax, and gave the whole a gentle curvature like the wings of a bird. When the work was done, the artist, waving his wings, found himself buoyed upward and hung suspended, poising himself on the beaten air. He next equipped his son in the same manner, and taught him how to fly.&quot; [https://en.wikipedia.org/wiki/Daedalus]<br />

Calculations and graphs are required to be included in your PDR. LaTeX is also strongly encouraged! Many examples of Latex documents have been generated (including this document) by the Rockets team. It should also be noted that for every plot, the required code/mathematics behind the plot should be included at the end of the presentation version of the PDR.<br />

Whenever a test of the concept is conducted on a smaller rocket, those rockets will also require a PDR. For example, if a team is planning to test a part of their system on an L1 rocket, they must write a text PDR for that specific L1 with the same sections. These do not have to be as in-depth however since a team will most likely be using a kit and modifying it slightly. The Systems Integration section will probably not be necessary as well, since it encompasses the entirety of the project (not a single test). Furthermore, L1 and L2 launches already have a Risk Management plan approved by Stanford, so the sections on Risk Management can be ignored.<br />
