Innovation with Unmanned Aerial Systems

The next frontier for unmanned aerial systems, aka drones, is to interact with people and the environment. Dr. Andrea L’Afflitto’s research is aimed at providing theoretical and technological solutions to this simple and yet challenging question: how can quadcopters and octocopters be used to help people in their tasks at home and work?

The challenges associated to this research topic are numerous, and his research group, the Advanced Control Systems Lab, has made exceptional progress in solving some of these challenges. For example, their control systems for drones are now able to override and correct a pilot’s hazardous maneuver. Moreover, small drones equipped with the research team’s autopilots are able to pick up and deploy objects, while remaining at a given location; www.ou.edu/coe/ame

existing autopilots are unsuitable for these purposes. In the near future, the team will implement robotic arms on multirotor aircraft, which will be used to manipulate objects collected during flight. This research would not be possible without the help of Dr. L’Afflitto’s research group, which comprises 14 of the most promising graduate and undergraduate students from AME. His research is funded by the National Science Foundation (NSF), the National Oceanic and Atmospheric Administration (NOAA), and the Army Research Lab (ARL) through the Robotics Collaborative Technology Alliance. Additional partners include the Oak Ridge National Lab and Microsoft, with whom Dr. L’Afflitto is collaborating on the creation of the next generation of flight controllers.

Dr. L’Afflitto received the Defense Advanced Research Projects Agency (DARPA) Young Faculty Award in 2018 for his research. AME News 2018

Heat and Mass Transfer in Multiphase Systems

Dr. Hamidreza Shabgard is an Assistant Professor in the School of Aerospace and Mechanical Engineering at OU. His research interests include heat and mass transfer in multiphase systems, CFD, thermal energy storage and heat pipes. Dr. Shabgard is currently working on experimental and numerical study of microencapsulated phase change slurries, various thermal desalination technologies, application of phase change materials in air conditioning systems, and multiscale modeling of liquid-vapor phase change processes in systems with various length scales. The experimental research is conducted using an apparatus developed by Dr. Shabgard’s group and enables a wide range of parametric studies to investigate the effects of various design and operational conditions on the heat transfer and hydrodynamic behavior of such multiphase heat transfer systems. The experimental and computational research on thermal desalination is focused on two novel designs based on evaporative and eutectic-freeze desalination. The 13

multiscale modeling relies on both Molecular Dynamics and CFD for better understanding of the transport phenomena occurring during vaporization and condensation of fluids adjacent to surfaces with various structures. In the “Multiphase Heat Transfer Laboratory” supervised by Dr. Shabgard, both experimental and advanced computational approaches are employed for better understanding of the complex transport phenomena involved in various types of multiphase systems. In addition to furthering the fundamental knowledge, Dr. Shabgard’s research finds application in a wide range of engineering applications including oil and gas, heating, ventilation and air conditioning, thermal management of electronics, desalination systems and solar energy among others. The broader impact of this research is paving the way for a more sustainable energy ecosystem by improving the efficiency of the existing systems and creating revolutionary energy conversion and management solutions.

Development of Novel Medical Device for Intracranial Aneurysms AME Assistant Professors Chung-Hao Lee and Yingtao Liu collaborated on the development of a novel medical device for surgical treatment of intracranial aneurysms. Incidental rupture of an intracranial aneurysm results in subarachnoid hemorrhage (SAH), which causes about 10% of an individual’s death before reaching medical attention. The overall objective of this research project is to identify objective hemodynamic and biomechanical criteria derived from predictive computer simulations for designing embolic devices and to develop the prototypes of embolic devices using aliphatic urethane shape memory polymers (SMPs), which possess excellent shape memory property, as a novel therapeutic technique for patient-specific endovascular embolization of intracranial aneurysms. The developed SMP foam-based embolic devices are expected to achieve short preparation time, optimal complete occlusion, and a significantly reduced rate of aneurysm recurrence.

The development of such innovative technologies is expected to be beneficial to the healthcare of Americans with a stroke history and will dramatically reduce the corresponding in-hospital expenditure. The collaborative team for this interdisciplinary research has been established among bioengineer Dr. ChungHao Lee (OU AME), material scientist Dr. Yingtao Liu (OU AME), and neurosurgeon Dr. Bradley Bohnstedt (OUHSC), as well as student researchers in various engineering disciplines of the Gallogly College of Engineering. This project is currently supported by the 2017 Gallogly SEED Funding for Interdisciplinary Research, Faculty Investment Program (FIP) sponsored by the Office of the Vice President for Research, and the Pilot Research Program from the Oklahoma Shared Clinical and Translational Resources (OSCTR).


Improving Software Tools for Analyzing Engineering Systems Dr. Keith Walters’ research interests lie in the area of computational fluid dynamics (CFD) simulation of complex fluid flow and heat transfer processes. His focus is on the development of physical models and mathematical algorithms to improve the accuracy and efficiency of computer simulations for a wide range of engineered and natural systems, especially those that include turbulent fluid flow. The size and complexity of these simulations requires the use of high performance computing (HPC) resources, such as those available at the OU Supercomputing Center for Education and Research (OSCER), and simulations often require hours or even days while running on hundreds of parallel processors. Example applications range from energy and biological systems to marine and aero vehicles. His research efforts produce improved software tools that are used by engineers and researchers in government labs, industry partners, and academia to improve analysis and design of complex systems.

www.ou.edu/coe/ame

Current research projects include the enhancement of CFD software for analysis of high-speed flow in Scramjet combustors, computational evaluation of novel wind turbine designs for improved energy efficiency, and the development and testing of new models for predicting heat transfer in liquid-metal-cooled nuclear reactors. Current research sponsors and collaborators include the Air Force Research Laboratory, Department of Energy, National Science Foundation, ATA Engineering Inc. and XPEED Turbine Technologies LLC. Dr. Walters’ research team includes three Ph.D. students and two M.S. students who actively contribute to the success of the overall research goals. At OU he hopes to expand his research into new application areas while continuing to train the next generation of computational fluid dynamicists and enhance the performance of computational engineering tools.

AE Undergraduate Feature: Tayera Ellis

Tayera Ellis is an enthusiastic senior Aerospace Engineering student at AME. With a clear vision of her future career goals, she attended the AT&T Summer Bridge Program before the start of her freshman year. During her Sophomore year, she traveled with Multicultural Engineering Program (MEP) to the Johnson Space Center in Houston, Texas. Tayera got her first inperson NASA experiences during this trip.

pressure vessels (COPs). After returning to school for a year, she received an official phone call from NASA in Houston offering her a Pathways Position.

During the same year, Tayera was the Vice President of the newly created “Sooner Rocket Team,” now known as Boomer Rocket Team and she was appointed Chief Engineer for her Introduction to Aerospace Engineering class final project.

In order to gain a different perspective in the aerospace industry, she interned with Spirit AeroSystems as a Stress Engineer in summer 2017. According to Tayera, “It seems as if I have spent more time interning than I have spent in school, but I know that without OU and the leadership opportunities I have gotten as an undergraduate, I wouldn’t have been competitive for the internship positions.”

“I think the accumulation of these leadership positions is what set me apart to get my first internship as a sophomore,” said Tayera. Tayera interned at Marshal Space Flight Center in Alabama, where she tested a mechanical system to verify a new tuned mass damper approach discovered by her mentor’s team. To continue gaining valuable NASA experience, she decided to delay her graduation and continue interning at a new location at White Sands Test Facility. Tayera helped verify a system that tested critical space hardware known as composite over wrapped www.ou.edu/coe/ame

“I got to be a test subject and wear an actual space suit! I met so many astronauts, and I was a part of the team that made it safe for them to go into space. The whole experience was so amazing!” said Tayera.

She is now the Project Manager for her Rocket Design Capstone project, for which her team is designing a cold gas nozzle system and testing each nozzle iteration to improve the design. Tayera’s future plans are to work for NASA and is taking the steps to meet the qualifications for a full-time position. She hopes to work in the same area that she got to work in during her time in the Pathways Position. AME News 2018

This experience provided Elisha with hands-on engineering practice as well as showed her the way in which engineers can influence or contribute to public safety using preexisting technology and therefore minimizing cost. Elisha is an active member of the University of Oklahoma Cycling Club, where she organizes and leads group rides, as well as introduce people to the discipline of bicycle racing. As a mechanical engineer, the design and mechanical aspects of the bicycle fascinate her even more than simply riding it. “Although the science behind bicycles seems to be simple and complete, bicycles are not just two-wheel human powered vehicles and there is room for a lot of improvement,” said Elisha. Consequently, she joined the engineering student competition team, Sooner Powered Vehicle. As the safety officer and an older member of the team, Elisha takes part in multiple design and administrative duties, such as writing the Safety Manual, making sure that the team members follow the workspace regulations, and presenting in team leadership meetings. Guy Elisha is a junior mechanical engineering student, pursuing her bachelor’s degree with a mathematics minor. She was born and raised in Israel and moved to Norway at the age of 16 after receiving a scholarship to study at a private international school called United World College. Elisha came to OU after receiving a full scholarship from the Davis foundation.

Elisha works as a mechanical engineering and mathematics tutor at the Student Learning Center, where she assists and instruct students in mechanical engineering and mathematics courses. The position involves collaborating with professors and fellow employees in developing effective teaching strategies, forming study groups and increasing students’ confidence.

As an honors student, Elisha was chosen to take part of HERE- Honors Engineering Research Experience, and had the great pleasure to work with Dr. Scott Harvey on a project that combined both civil and mechanical engineering. The research examines alternative, affordable and safer methods to determine the shape of a building in the aftermath of an earthquake. During this period, she was exposed to a large-scale lab environment, processed data, met and communicated with a range of people with different academic backgrounds, and gave presentations about her work. Moreover, as a co-author, they sent two academic papers to publish, in which one of

Due to Elisha’s interest in learning, teaching, and research, she sees herself staying in school and extending her academic career, possibly pursuing a Ph.D. in mechanical engineering. Having her first academic paper accepted for publication as an undergraduate encouraged her to continue along this path. In Elisha’s future studies, she hopes to continue to look for affordable and sustainable ways to increase people’s safety and quality of life. Her goal is to work for improving and expanding the field of renewable energy by looking for ways to increase efficiency and decrease the cost such that it will be affordable.

Graduate Student Feature: Marcus Brown

Marcus Brown is a Ph.D. student and graduate research assistant for Dr. Rong Gan. His research includes the biomechanics of the ear and finite element modeling of sound transmission throughout it. Specifically, Brown’s recent work has been investigating how blast waves (like the pressure wave from an explosion) affect the inner ear and contribute to hearing loss. In October 2017, Brown presented his research, titled “3D Finite Element Modeling of Blast Wave Transmission from the External Ear to the Cochlea,” at the BMES annual meeting. Also, he did some imaging to visualize the damage done to the inner ear. He used the Samuel Roberts Noble Microscopy Laboratory at the University of Oklahoma (OU) to take scanning electron microscopy (SEM) images of the hearing sensory cells in the inner ear to visualize the damage done by the blast waves. In February, this study was presented by a poster titled, “SEM Imaging of Cochlear Hair Cell Damage Caused by Blast Exposure,” at the ARO 41st Annual Midwinter Meeting. Brown has held multiple teaching assistantships at the University of Oklahoma. These appointments were www.ou.edu/coe/ame

both in the AME and BME departments. The range of classes include: statics, design of thermal fluid systems, biomechanics, bioimaging, and capstone. After receiving his master’s in mechanical engineering at Purdue University, Brown worked as a Systems Engineer at Nanosphere, Inc. In this position, he worked in product development, designing and testing new instruments, in order to ready them for clinical trials and FDA clearance. In addition, Brown determined the requirements and technical hazards, and performed verification and validation testing for new and existing products. “I consider this career path to be where I will have the most impact on the improvement of medical therapies,” said Brown. “Working in a research laboratory (academic, national, or industrial laboratory) would make the best use of my experiences gained thus far and the knowledge I’ll gain while completing my Ph.D.” After graduation, Brown would like to apply the skills gained at the University of Oklahoma to further advance biomedical technology through research.

Bass Family Bike Project

The Bass Family asked the team to find a way to allow their son, Titus, who is physical and mentally handicapped, to participate with their other son, Tobias, in the cycling portion of a triathlon. It is Tobias’ dream to be the youngest person to complete the Ironman triathlon while accompanied by a disabled partner. After meeting with the Bass Family and researching several ideas, the team decided to follow through with a sidecar design for Tobias’ bike. The sidecar includes a steel frame, fiberglass nose shell, and arms that can detach from the frame of the bike. The fiberglass nose shell is connected to the front of the sidecar frame by hinges, allowing the shell to open and close. This will make loading Titus in the sidecar an easy task. The sidecar is attached to the frame of the bike with attaching arms that have clamps at the end. These clamps allow the user to attach and detach the sidecar. The position of the third wheel of the sidecar is also adjustable. The height and lateral position of the third wheel can be adjusted using similar clamps. A 3D model of the sidecar frame was designed in SolidWorks. Several loading simulations were performed on the frame using ANSYS to ensure safety. The results of the FEA showed that under the loading conditions, the sidecar frame would remain a safe option for Titus. Tests on the actual prototype were also done by the team. 29

Again, the results showed that the sidecar was safe. The sidecar designed and manufactured by the team provides Titus and Tobias a light-weight and low-cost solution to their initial problem.

The School of Aerospace and Mechanical Engineering’s own Dr. Zahed Siddique accompanied engineering students on a one-month trip to Arezzo during summer 2017. Faculty and students had the opportunity to sightsee around other cities in Italy, such as Florence and Rome. They visited with industry leaders in engineering, such as General Electric’s Nuovo Pignone where they were guided around by Dr. Massimiliano Cecconi. Additionally, students and faculty also toured the Pantheon and Colosseum in Rome and even did group projects such as making homemade pasta. While students were in Arezzo, they worked on completing a project for the city’s mayor, where the students split into

groups and commutatively designed an innovative phone application that focused on helping people explore the city of Arezzo. Towards the end of the student’s trip, they presented their project to the mayor and city officials. In addition to the final project, courses are also offered for engineer majors while they’re in Italy. Course include: ENGR 4510 - Design Thinking and ENGR 4510 - Global Communication. The students, along with Dr. Siddique and other faculty, gained a wide array of experiences while on their trip to Italy, not only with classes, but with the cultural experience as well.

Solar Eclipse

On Monday, August 21, 2017, North American witnessed an amazing solar eclipse. It was the first total solar eclipse visible in the United States in the past 38 years. The path of totality (the path that the moon’s shadow traces on Earth during a total solar eclipse) stretched from Lincoln Beach, Oregon to Charleston, South Carolina. The University of Oklahoma was outside the path of totality. However, a partial solar eclipse, with 83.48 percent obscuration, brought all of campus outside to look up at the sky together. Due to the strength of the sun, it was very important to have the proper eyewear. For this reason, Dr. David Miller brought extra pairs of the special glasses to the Engineering Quad for everyone to share and enjoy. He also setup his telescope with the proper lens to make it safe to look through. Engineering students fashioned their own solar eclipse viewing apparatus out of cracker boxes, aluminum foil, paper and cardboard. Around 12:06 p.m., the maximum obscuration of the solar eclipse occured. Miller encouraged everyone to look at their shadows on the ground as well as the solar eclipse. The shadows created by the obscuration mimic the crescent shape created by the moon overlapping the sun. Instead of seeing a complete shadow, it creates a whispylooking version of one. The solar eclipse viewing in the Engineering Quad gave everyone a chance to enjoy the miraculous event. 31


Student Teams


OU Design Build Fly Places 6th at Competition

The Design Build Fly Crimson Skies team finished sixth out of 95 teams at the AIAA DBF competition in Tucson, Arizona this year! The team finished all missions and received many compliments from judges and competitors on the novelty of their inflatable fabric wing. SpaceX, Raytheon, Lockheed Martin, Textron, and Northrop Grumman were just a few of the companies on-site recruiting. A SpaceX recovery systems employee was particularly interested in our inflatable wing and came by our work tent several times to chat with students. According to the DBF rules, student teams had to design, fabricate, and demonstrate the flight capabilities of an unmanned, electric powered, radio controlled aircraft that could best meet the specified mission profile. The goal was to have a balanced design possessing well-demonstrated flight handling qualities and practical and affordable

manufacturing requirements while providing a high vehicle performance. The objective for this year’s competition was to design a tube-launched Unmanned Aerial Vehicle (UAV). The UAV must fit complete inside the launch tube, which also acts as the UAV handling and storage container. The launch tube must protect the UAV from damage during normal handling and storage. Upon removal of the UAV from the launch tube, all folded or stowed surfaces or features must move into the flight condition. Teams had to design a UAV and launch tube that minimizes system weight while maximizing speed, range, endurance and payload capacity. DBF Crimson Skies tested multiple designs before creating the successful “Batwing II,” which is the given name of their winning aircraft.

Capstone Project Sponsorsip Options The Mechanical Engineering Capstone program has grown in size tremendously in recent years, and AME is in need of additional industry sponsored projects to support our large student cohort for Spring 2019. For many years, our capstone program has collaborated with industry sponsors to provide “real-life” industry projects for our seniors to complete during their final semester in school. These projects allow AME 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 cdalton@ou.edu.

Project Identification Projects in most areas of mechanical engineering, including mechanical design, thermal or fluid systems, control systems, etc., are accepted. The successful completion of these projects is as important as the instructional and educational value. The following guidelines are offered to identify a suitable project for the program. • • • • • • • • • •

35

Choose a problem that you really want solved. Choose a project that emphasizes design, experimental, and hands-on skills. Do not choose a project involving only the collection of published materials. Choose a problem that allows teamwork and offers opportunity for creativity. Avoid projects involving classified materials. The project scope should be limited to about 1000 person-hours of a senior engineering intern. The project schedule should be limited to about six months (mid-October to April). Seek a project that is not on the critical path of a program with a stringent deadline. Establish concrete, measurable goals. Define how success will be determined.
