STUDENT
GENERATION
In the Advanced Class, teams released gliders
with autonomous guidance to a ground
target. Shown here is the airplane of Wroclaw
University of Technology and its two gliders.

AIR
MISSION
Introduction of autonomous gliders were
among the changes implemented for
SAE Aero Design 2019.

FOR THE FIRST TIME IN SEVERAL YEARS, different teams won the six Classes in the
twin 2019 SAE Aero Design competitions. Perennial powerhouses Georgia Tech and
Warsaw University of Technology each were victorious in a Class, with three separate
Chinese teams and one Canadian team also claiming Class crowns.
SAE Aero Design competitions feature three main scored Events for which teams can
win first-, second-, or third-place trophies: Design, Technical Presentation, and Mission
Performance. Also scored (but not considered an "Event") is a "Demonstration" in which
teams are timed on how long it takes for two teammates to assemble their Micro Class
plane. Part of the requirement for the Demonstration is that the plane be designed in
pieces so it fits inside a box 12.125 inches by 3.625 inches by 13.875 inches.

8 September 2019

The first competition of the year was
SAE Aero Design East in Fort Worth,
Texas, where strong gusts were a factor
on the first flying day following the initial
day of indoor technical inspection and
technical presentations. A high number of
Micro Class planes went into immediate
nosedive, and some teams in the various
Classes passed on flight rounds for fear
of crashes. But the winds died down later
in the first day and were a nonfactor in
the second day. Coming out on top in
the Micro Class was Ningxia University of
China, edging out Georgia Tech.
"Winning the first prize is the best
feedback for our team's years of efforts
and a year of careful preparation, which
has increased the confidence of our
team members, accumulated valuable
experience in aircraft design for our team,
and increased the honor for our team,"
Ningxia University team captain Jin
Zhang told MOMENTUM.
The most interesting engineering
feature of the Ningxia team's plane
was the structural design for the rapid
assembly of the aircraft, Zhang continued.
"In order to reduce the assembly time
and maintain the overall strength, the
team broke down the parts of the model,
broke them into parts and numbered
them. Various quick-disassembly and
quick-assembly structures among the
components refer to model aircraft such
as DLG. Take the wing as an example:
the connection strength between the
outer wing segment and the middle wing
segment is mainly ensured by carbonfiber bolt, and the magnet is added as
the auxiliary bolt creatively. This can not
only prevent the torsion between the
segments, but also enable the segments
to automatically snap when approaching,
saving assembly time."
The team earned 15.5 Demonstration
points, second most among all
competitors in both SAE Aero Design
competitions. Only Georgia Tech earned
more points (22.7).
"The assembly may look simple, but it
took a lot of aligning and assembly lock
features for it to actually work," Georgia
Tech Micro Class team captain Ogun
Kargin is quoted as saying in an article on
the university's website. "It took us about
four months to perfect the locks and align
them in such a way to keep the plane from
disassembling during flight."
