THE 2013 COMPETITION IS OVER - WE HAVE A WINNING TEAM! (Updated 11:30am, 5/13/2013)
Congratulations to Team Kevin! They are the 2013 Bronze Propeller champions!
The last day of competition flying was held on Sunday May 12th. The following outlines results and other bits of information on the 2013 event:
The 2013 competition results are as follows:
Congratulations to all the teams who flew:
Special thanks to the competition pilot - Jonathan Mowrey. He flew everything and he flew well! Lots of amazing saves on windy days and with tricky planes!
Jonathan Mowrey - The Pilot
The Aerospace Engineering department annually sponsors an aircraft design competition for university and high school students. The goal is to encourage involvement in a fun and educational activity.
Competing teams design and build an electric powered remote controlled aircraft to fly a challenging mission. Winners get their names on the Bronze Propeller Trophy. The fourth annual competition will be held in April 2013.
Any student can compete. Don't be shy. Form a team, build a plane, and fly! Mentors for high school and underclassmen student teams are recommended. Contact Dr. Miller for help finding a mentor.
Participating high school and graduate student teams compete in separate categories. The graduate students are required to utilize "very unique design configurations."
Start watching this page in August for information on the 2013-2014 competition!
Just for your reference, the material below reviews the 2012-2013 competition.
2012-2013 Mission, Rules, & Guidelines
This year's mission is a "High-Efficiency Cargo Hauler."
In short, you are to design a plane that can efficiently takeoff, fly to a designated location, collect a big payload, and fly back as fast as possible. Interestingly, all aircraft will utilize the same power system this year (i.e., batteries).
A successful mission profile includes the following:
0) Install the WSU supplied data and power system
1) Takeoff empty (i.e., no payload)
2) Fly two complete laps
3) Land and quickly load the payload (softballs)
4) Takeoff and fly at least two more complete laps
5) Land successfully
Additionally, planes must meet the following minimum requirements and constraints:
The flying area dimensions are approximately 400x100-ft. Planes are expected to fly within this area at all times (under about 100-ft altitude). The runway will be in the center and turns will be approximately 300-ft apart (perhaps around light poles).
The mission score (SCR) is calculated using the following equation,
SCR=NB + (1,000/MT) + (10,000/MAH)
Where NB is the number of softballs carried during the last two laps, MT is the total mission time (seconds), and MAH is the total energy consumed (mAh).
Mission timing begins the moment the WSU supplied data and power system is issued to the team. The timer is stopped when the plane touches down after completing the entire mission.
Payload (i.e., softball) installation is performed by just two team members and only in a designated 10x10-ft area. The mission timer will not be stopped during loading.
Required Power and Data System
The WSU supplied power system operates the motor, receiver, and servos. The operating voltage is approximately 10.5V (loaded) and the current output will be electronically limited to 30A. (Click here for additional battery test data.)
Maximum available battery capacity is approximately 2,000 mAh. The dimensions and weight are, respectively, approximately 1.25”x2.5”x5.5” and 12oz.
The data system also records the energy used (in units of milliamp hours, mAh) during mission execution. It weighs approximately 10oz and is roughly 1.5”x3”x8” in size.
The WSU supplied data system can also be used to collect critical flight data for later analysis (e.g., airspeed, altitude, attitude, rates, heading, throttle setting, etc.). A telemetry and SD-card recording system are planned.
Additional space within the aircraft should be planned to include a protective foam wrap for both the power and data systems (this will increase dimensions). This provision is needed to minimize system damage in the case of a very undesirable incident (i.e., crash).
The battery must be located within approximately 2-inches of the data system. More specific details on the WSU supplied data and power system will be released shortly.
All rules, requirements, and constraints are subject to interpretation and change by Dr. Miller. Additional rules, requirements, and constraints can be added anytime. Team members assume all risk with respect to disqualification (i.e., SCR=0).
A successful design is well understood and properly developed from the beginning. Don’t let someone create a better overall design than you.
Use engineering principles and methods to win!
Mini-Grants & Mentors
The planes will be inexpensive to build. However, some teams may be eligible for limited AE department assistance to help build their plane (e.g., radio gear, motor, assorted supplies, laser cutting, foam cutting, etc.).
Additionally, the department will do what it can to provide mentors to help less experienced teams.
Deadlines for submitting department support, laser/foam cutting, and other requests will be established in the spring semester. Teams must meet these deadlines.
Contact Dr. Miller for further information on mini-grant and mentor opportunities.
Engineer of 2020
Eligible WSU students, especially seniors, can gain “Engineer of 2020” service-learning credit by serving as a mentor for less experienced teams. These opportunities must be prearranged. Contact Dr. Miller for further information.
