Topics of discussion: Minutes from December 15th meeting, Big Brother Big Sister Event, Meeting Business
Unfortunately I was not present at the December 15th meeting and I now have the information of what occurred during that meeting. Two presentations were conducted with respect towards the Quad-Copter Project. The first presentation was conducted by Luke Ivan and consisted of the following:
Luke Ivan - Quad-Copter
Project
Environment:
Indoors or outdoors
Design
Off the market or own design
Ease of repair
We will crash it several times before
we learn how to fly it. It will need to survive multiple
crashes
Control-focused, or payload-focused
Functionality
Video, comm, terrain navigation (GPS
enabled?)
Individual and formation flying
(proximity detection)
remotely controlled (laptop)
Basic quad-copter parts
Frame
Motors and propellers
Need at least twice the thrust of
what the copter weighs
(GW=10lbs, need 20lbs of thrust) Power system -
Lithium battery
Dome - to protect components
Software - programming flight
controls
Payload - Cameras, etc.
Work Breakdown Structure
6-level indented structure
Managerial level
Total program (authorization and
release of work)
Budget
Schedule
Technical level
Subtask
Work package
Level of Effort
Next Steps
Brainstorming session
Plan development
Sponsor approval
Budget request
Design
Acquisition (parts and/or
off-the-shelf)
Assembly
Testing
Demo
Luke's Vision
Three quad-copter units, linked via
video & comm
Proximity enabled
Flying as one unit (formation) -
centrally controlled
Videos: "AeroQuad" off-the-shelf unit, flying solo.
Frame demonstration: off-the-shelf
components, aluminum square
tubing from Home Depot Hoverfly quadcopter
control system intro
Hoverfly quadcopter frame building
Following these links will help you gain a better
perspective of the quad-copter and show ideas of others
who have worked with quad-copters

The second presentation was conducted by Fred Porter and
consisted of the following information:
Fred Porter
University of Pennsylvania has done a lot of development
on "swarms;"
he also recommends YouTube videos of their work with 16
such vehicles
coordinating among themselves.
Lithium-polymer batteries may pose fire risks; at the
academy, they
carried shovels to extinguish them if the cases
ruptured.
Plasma flight control:
Changing flow over control surfaces
changes flight characteristics; this project was to vary
electromagnetic
fields to ionize air particles to
change the flow. 6000V +/- and 6000hz. How to create
those voltages? 1oz
power supply found at the state fair for a novelty electric toy. Pulsing 1A current at 6000hz, needed a relay to
control. Needed servos and controlling circuits inside a metal box to isolate from magnetic flux lines of this
power supply. (Even a pinhole in the side of the enclosure resulted in too much noise/magnetic interference).
Performance of electric control surfaces vs.
mechanical was only about 5%. Not
all of the air needed to
move; only a small amount is needed
to "seed" the flow.
Discussion: altitude sensing, weather conditions near
the ground
Fred provided several examples of
landing challenges for aircraft in his experience. For
rotorcraft, power loss is
dealt with through "autorotation."
Propellers: greater numbers of blades
means it can get more thrust at slower speeds. At higher
speeds, we want
to get rid of those extra blades. Diameter and chord: diameter is like the "wingspan," and chord is the width,
from leading edge to trailing edge. At low speeds, we want a lot of blade chord; at high speeds, we want less
for lower friction drag. Lot of lift, higher pitch angle. More horizontal translation speed, maybe less pitch
angle.
Hydrocarbon fuel, as it burns,
lightens payload and performance improves. Electric
batteries don't get lighter
as they fly. Vibration management: if a piece falls off, creates imbalance, it should be brought down as quickly
and safely as possible because vibration can
destroy the aircraft.
Regulation: 20 lb. limit imposed by
the FAA, also 1 mile range.
Big Brother Big Sister Event
The CTU IEEE is looking for volunteers for the Big Brother Big Sister Event that we are holding. This
event will be held the 26th of January in the Engineering Labs. Volunteers will assist in setup and teardown of
the lego-mindstorm road obstacle course, and assisting children in program setup. If anyone is interested in
volunteering for this event please let me know.
Meeting Business
There was a short discussion of the acknowledgment of members participating in the CTU IEEE. In order to be
in good standing with the schools local branch a receipt needs to be on file with Robert Schnoor, the CTU IEEE
treasurer. If you have not given Robert Schnoor a copy of your receipt to be reimbursed half of the
membership cost than please either bring a copy to the next meeting or email me a copy so that I can forward it
to Robert.

LD Steiner Lucian Ivan Esther Banks John Santiago
Josh Soliday Marc Olson Wenton Davis
Robert Schnoor Michael Garcia Dr. Don Schley
Topics of discussion: Presentation on Power Systems Design Project, Presentation on Project Management, and Chapter business.
LD started off the meeting by giving a presentation demonstrating ideas others have put to use involving solar and wind powered systems. He then discussed some of the materials he researched online that can be used to construct the solar and wind power system that charges a deep cycle battery that will be used to power a load. This will also power a CPU that will be programmed to monitor and collect data for the power produced by the wind turbine, solar panels, and the power to the load.
Guest speaker Dr. Don Schley gave an excellent presentation on project management that walked through the process of going from an idea to completion of the project. He explained how each stage of project management relates to the engineering field and gave some very good examples of how project management has been used to build and design systems we know today. His presentation really helped give us an idea on how to organize our thoughts into a plan that can be implemented.
With chapter business we discussed plans on getting the other two projects presented and getting the groups organized so everyone can begin share their ideas for implementing the project. If you are interested in participating in any of the projects please send me an email letting me know so I can add your name to the list. We also discussed some community events coming up. In January, Century21 (Big Brother and Big Sister) are coming to CTU and we are looking for volunteers to design activities dealing with Lego Mindstorms. More information will be available for this event in December. We are also looking for volunteers as judges for The Pikes Peak Regional Science Fair in March. If you are interested in participating in any of these community activities please let me know. We also discussed the CTU polo-shirts with the IEEE logo added to them. Robert Schnoor can get a deal of 30 to 40 dollars per shirt if we buy in bulk so if you are interested in getting one of these polo-shirts let me know so we can get an idea of how many to order. As a reminder I have listed the projects below with a list of the names I have for each.
