TUCSON, Ariz. — Trine University had its best finish ever at the American Institute
of Aeronautics and Astronautics (AIAA) national Design/Build/Fly Competition, held
April 10-13 at TIMPA Field in Tucson, Arizona.
A team of senior mechanical engineering students placed 43rd out of 108 at the competition, a 12-place improvement from last year. The Trine team
was one of three recognized as “Best Senior Design Team.”
This year also marked the first time a Trine team completed the second of three missions
involved in the competition.
Team members were Hailey Budney of Lake Hiawatha, New Jersey; Dillon Dennison of Ithaca,
Michigan, Matthew Edison of Russiaville, Indiana, Bryan Maida of Lockport, Illinois,
Nathan Mast of Middlebury, Indiana, Ryan McDonald of Valparaiso, Indiana, and Cassidy
Victor of Fraser, Michigan.
Design/Build/Fly
Now in its 29th year, the Design/Build/Fly competition tasks students with designing, fabricating
and demonstrating the flight capabilities of an unmanned, electric powered, radio-controlled
aircraft.
Design requirements and performance objectives are updated for each new contest year.
Mast said the Trine group spent extra time consulting with area radio-controlled airplane
pilots to make improvements to this year’s design.
“We began with dividing into different jobs and researching. Then, through the engineering
design process, we decided on a design,” he said.
The team refined its composites manufacturing process and ran stability analysis tests
to further enhance their design. However, frequent testing — and crashing – took
a toll on their budget.
“We made critical improvements on the structure and thoroughly analyzed the crash
to ensure the same mistakes weren't repeated,” said Mast. “Through multiple tests,
crashes and iterations we ended up with our final design.”
Three missions
The competition consists of three missions. This year’s event involved flying with
an attached glider in the last two missions.
In the first mission, teams flew three laps with no payload or glider.
“Mission 1 went fairly well until the battery began to run out of charge, causing
each lap to be lower in altitude,” said Mast. “Thankfully, the pilot was able to land
the plane successfully.”
For the second mission, teams flew three laps as fast as possible, with as much payload
as possible and the glider attached.
“Mission 2 went perfectly. We hadn't had a chance to test the plane with the full
payload, so we were nervous going into the attempt,” said Mast. “The plane handled
the payload well and landed smoothly.”
The Trine team was hampered by strong winds during the third mission. They were supposed
to fly as many laps as possible with no payload, then release the glider and land
the glider autonomously in a bonus box on the ground.
However, the plane crashed during its takeoff attempt due to the wind.
Though it ended with a crash, Mast said the team felt this year’s effort was successful
and allowed them to develop manufacturing techniques that will help future teams to
create more complex planes.
“The plane performed better than expected and performed to what we designed it to
do,” he said.
