Imraan Faruque, Ph.D., gave a presentation on Monday, March 25, 2019 on how biologically-driven flight control strategies can inform unmanned aerial vehicle swarms. Dr. Faruque is an assistant professor for the Department of Mechanical and Aerospace Engineering at OSU.
Abstract: This seminar introduces a framework for deriving feedback design principles that can enable insect-based flight control approaches on unmanned aerial systems (UAS) and engineered extensions to groups of UAS. The seminar begins by establishing flight dynamics models of dipteran flapping wing insects, combining automated high-speed videography measurements of freely flying insects, experimental aerodynamics results, rigid body dynamics, and system identification techniques to distill high fidelity flight dynamics models into computationally-tractable models applicable to flight control analysis. Methods to extract models of the closed loop controllers implemented on insects from free flight trajectories are discussed. Linear matrix inequalities are applied to interpret the controllers into design principles that can translate the extracted controllers into those appropriate for engineered vehicles, and improvements in experimental techniques to quantify multi-agent aerial insect behaviors. Control-theoretic definitions of reachability are applied to the aerodynamic mechanisms involved in insect-scale flight control and gust response, leading to a theoretic framework for the gust response properties of closed-loop flight control and the engineered design of gust-aware flight controllers.

Sarah Ciccaglione, an aerospace engineering student, was featured in the “Crimson Spotlight” segment of the Inside OU newsletter on March 13, 2019. In the video, she speaks about her involvement at OU and how the School of Aerospace and Mechanical Engineering has made her feel at home.
Ciccaglione is a member of the Sooner Racing Team. She enjoys the mechanical systems behind the cars and competing with her team. Ciccaglione is interested in the technical side of aerospace engineering and she enjoys the math and science involved in her major. Furthering her career in the engineering field, she also got the opportunity to intern with Tesla in Palo Alto, California.
Ciccaglione is very involved on campus. She is a member of the rowing team and double majors in aerospace and vocal performance. Ciccaglione loves all of the opportunities that OU provides for its students and the support system she has gained.

AME was one of the selected schools to be featured on the TECAID website with WEPAN. This website focuses on transforming engineering culture to advance inclusion and diversity. TECAID is an active program in which engineers can learn about the environment they are in while learning about their skills and knowledge. They focus on how to create the best personalized experience for their engineers.
We are now highlighted in multiple Webinars (2 and 3) along with a photo of the OU team. An interview was done with our director, Dr. Zahed Saddique. The interview can be found at this link: https://www.wepan.org/mpage/TECAID_MechEngDepts
We would like to thank Phil Dineen who served as TECAID’s web designer and ASME who provided funds to make these final updates possible.
For 24 hours on Tuesday, the University of Oklahoma hosted Giving Day, a campus wide fundraiser to help our students and programs! Overall the University raised $477,764 through 2,123 gifts.
The engineering department raised $96,100 with 459 gifts and AME’s own ambassador, Rebeka Morales yielded the most gifts university-wide. AME had an encouraging message from Dr. Siddique to get the donations started and a donation center in the Hitachi Conference room where students could donate between classes.
AME would like to thank everyone who donated to support our amazing student teams! They have big goals and with your support that are even closer to reaching them.
Thank you to our challenge from Michelle Coppedge who matched $1000 after we raised $1000 and another $1000 after we obtained 30 total gifts.
Your school needs your help! The Mechanical Engineering Capstone program has grown in size tremendously in recent years, and we are in need of additional industry sponsored projects to support our large student cohort for Spring 2018.
For many years, our capstone program has collaborated with industry sponsors, like you, to provide “real-life” industry projects for our seniors to complete during their final semester in school. These projects allow our students to successfully demonstrate a variety of skills that future employers prize: analysis, design, teamwork and communication skills to name a few. Ideally, the project will feature some elements of a design process and be suited for a team of 3-5 members for a period of 15 weeks. We are also interested in interdisciplinary projects that may involve industrial or electrical engineers as well.
If you believe your company may be able to assist us, please contact Dr. Chris Dalton at email@example.com.
Dr. Hays’ Aerospace Structures class tested their UAV Wing Structural Design and Destruction projects on March 24, 2017 in the Rawls Engineering Practice Facility.
The task description was to design the structure of an assigned UAV wing outer mold line. These wings were placed in a table testing mount and loaded with sandbags corresponding to the lift distribution across the wing. While this is an older method of testing, it is still very much in use today and serves as a very definitive demonstration of strength. The objective was to construct a suitable wing structure to carry the defined load while keeping the overall structure as light as possible.
AME student, Robert Anderson, was awarded the Oklahoma National Science Foundation (NSF) Established Program to Stimulate Competitive Research (EPSCoR) Summer 2017 Research Experiences for Undergraduates (REU) program. According to the EPSCoR website, “Award recipients, under the guidance of faculty mentors, will perform climate variability research at the University of Oklahoma in Norman and Oklahoma State University in Stillwater.”
The student researcher will be under the guidance of Dr. Andrea L’afflitto to conduct research titled Summer Research Experience: Programming UAS for Improved Weather Forecasts.

A group of students from Dr. Andrea L’afflitto’s Flight Controls class created the following video:
According to Dr. L’afflitto, this project consisted of designing an autopilot for a quadrotor using some modern, very aggressive control techniques. The purpose of this video is to show the results achieved graphically, however, the mathematical models, the control design problem and the numerical simulations have very deep roots.
“I am extremely proud of their work because these are all undergraduate students, but the quality and the mathematical complexity is the one of a graduate project,” said Dr. L’afflitto. “We all can imagine the impact of the development of such technology, considering the growing attention that OU is putting on the UAS technology.”
This video shows the result of a students’’ project developed as part of the AME 4513/5513 “Flight Controls” course at the University of Oklahoma in Fall 2016. A DJI F450 will inspect some buildings of OU’s main campus. The drone’s autopilot implements an algorithm based on Model Reference Adaptive Control.
An important feature of this simulation is that the quadrotor dynamics is not captured by a set of nonlinear differential equations, but it is deduced from a SimMechanics model of a DJI F450. This guarantees high accuracy of the results presented.
The adaptive control technology allows precise, aggressive maneuvers in the vicinity of obstacles, such as buildings.
Next, we compare the performance of a quadrotor (in white) implementing an adaptive control law and a quadrotor (in black) implementing a classic PID controller.
