Date of presentation: 20 Feb 2017
Subject: STEM kit - Quadcopter
Description: From an email sent by David on 15-Feb:
----------
I finally received the "Build a Quad Copter" STEM kit. Here is a summary of what I had put in the request for the kit:
- Build the quadcopter with a couple senior members, include a couple cadets from Squadron 36.
- Perform a density altitude experiment:
- Fly in a cold environment, perhaps in a park outside in the morning. Baylands is a good park for this, Steven also suggested the RC park near Morgan Hill. Suspend a weight at the center of gravity, find the maximum that can be lifted.
- Fly in a warm environment, perhaps the Squadron building with seats removed and the heater running. We should see that the max weight is less.
- Give the following presentations to both Squadrons 80 and 36 as part of our AE program:
- General aerodynamics of a quad copter (Wikipedia on Vortex Ring State, Forbes article on what makes quadcopters so great for small drones).
- Use of drones, both commercial, hobby, SAR, and military.
- Effects of Density Altitude.
- (The above could be combined into one long preseo depending on the amount of content)
