PART OF THE SAE COLLEGIATE DESIGN SERIES, SAE Aero Design
challenges college students to apply theory to practice in the process
of designing, making, testing, and optimizing a model aircraft meeting
specific mission objectives. At the same time, it can also help them
to improve interpersonal communication skills and written skills by
submitting a design report and making an oral presentation.
SAE Aero Design consists of two separate competitions, with some
teams participating in both. SAE Aero Design East for 2019 was held in
Fort Worth, Texas from March 8 to 10, SAE Aero Design West a month
later in Van Nuys, Calif.
There are three classes in each individual competition area: Micro
Class, Regular Class, and Advanced Class. Ningxia University's
Aeromodelling Team participated in the SAE Aero Design East Micro
Class along with 84 other teams from nine countries.
Located in the Midwest of China, Ningxia University is a
comprehensive university in scope except that it does not offer
an aviation major. Nevertheless, Aeromodelling has accumulated
rich experience in aircraft design, production, and performance by
participating in the China Aeromodelling Design Challenge (CADC) for
many years. CADC is a university aviation design brand competition
focused on China. The team participated in the British BMFA 2017 as
well as SAE Aero Design West 2018 in the Micro and Regular Classes. So
it has a good understanding of SAE's technical requirements.
Aeromodelling had been preparing for SAE Aero Design East 2019
since May 2018. The team consists of Jin Zhang, Wanying Lv, Mingyuan
Liu, Yan Yao, Jiale Yao, Lei Xu, Wei Luo, Yongjing Zhuo, Xiaobin Wang,
Chen Huang, Pengfei Ren, Yue Ma, and Bo Ma. The instructors are
Hongbo Zhang and Yinhu Kuang. During preparations, Yongxin Li, Funan
Wang, and other coaches from Beijing University of Aeronautics and
Astronautics provided technical support.

A week after the end of the SAE West 2018, Aeromodelling officially
launched preparation for the 2019 event. The team set a goal of 120% of
the highest mark in 2018 to win the championship. The competition rules
change significantly every three years, so we boldly inferred the rules
would not be changed greatly for the 2019 competition. Therefore, we
modified the 2018 model to align with the minor changes of 2019 rather
than design a new airplane from scratch.
At the same time, we started flight training and preparation of the
Design Report (Design Report is one of three primary scoring categories,
the others being Mission Performance and Technical Presentation).
When the rules were officially released in September, they were exactly
what we'd expected. In October, we were informed that we qualified to
participate in SAE Aero Design East 2019.
The Micro Class challenge is to design a portable micro UAV style
aircraft that can be deployed rapidly from a small container (max outside
dimensions: 12.125 X 3.625 X 13.875 inches). For take-off, the plane must
be thrown by hand from a designated area, and in flight it must carry
a bulky, low-density payload: American-standard 2-inch-diameter PVC
pipe. All of the plane's parts and payload must fit into the container.
Because the empty weight of the model should be as small as possible
and the payload should be as heavy as possible, "Making great efforts to
decrease each gram of weight" became the motto of our design team.
When it came to reducing the empty weight, the selection of
materials was essential. Thus, we adopted the method of software
analysis together with experimental testing. According to the results
