EPVSensors Takes a Closer Look at Glaucoma

A company co-founded by professor Eniko Enikov recently licensed a novel design for a non-invasive tonometer that measures intra-ocular pressure for glaucoma detection. The invention is the first to take measurements through a closed eyelid.

Aerospace and Mechanical Engineering Seniors Dominate Design Day Stage

Aerospace engineer Theodore Von Karman once said, "Scientists discover the world that exists; engineers create the world that never was." Everyone who attended the UA College of Engineering’s 13th annual Engineering Design Day this past May would certainly agree. Approximately 400 UA engineering seniors on 77 multidisciplinary teams wowed the crowd with a wide range of projects that showed us pieces of that “world that never was.”

Aerospace engineering seniors were a force to be reckoned with, with four teams winning top awards, while mechanical engineering seniors helped push 17 other interdisciplinary teams into the awards spotlight, attesting to the versatility, strength, and applicability of their skills.

Team 1461, on the project "X-56A DART: Dynamically Scaled Aircraft for Research and Testing," received the CAID Industries Innovation in Manufacturing Award for their design of a modified straight-wing version of Lockheed Martin’s swept-wing X-56 Multi-Utility Technological Testbed for testing flutter suppression and gust...




Sabino Canyon's Eye in the Sky

Congratulations to Team 1463 for winning the Ventana Award for Innovation in Engineering at Engineering Design Day 2015!

The project was to design, manufacture and test fly an unmanned aerial vehicle with vertical takeoff and landing capabilities. Rincon Research Corp. wanted to develop a drone with the purpose of providing surveillance information for Sabino Canyon.

"It was a huge learning experience; since I was team lead, I learned a lot about being in charge," said May 2015 graduate and aerospace engineering major Steven Rishor. "I was able to keep up the team's morale and the pace of the project. Time was a big priority on this project because we had to build it from scratch."

In a departure from specs provided for other projects on Engineering Design Day, the team was given a mission profile, with no existing design for the VTOL which the team could model after.

The mission was to vertically take off and fly to a location four miles away, cruise around in a half-square mile, flying at an altitude of 500 feet and then return within 30 minutes.

“We were having a problem...




Modify Your Flight


Congratulations to our AME Team 1461 for winning the CAID Industries Innovation in Manufacturing Award at Engineering Design Day 2015!

The goal of the project was to design and build a half scaled model of a X-56A Dynamically Scaled Aircraft for Research Testing. The team modified a version of the aircraft with straight wings and a tail that would perform the same as the original swept wing.

Professor Hermann Fasel, an expert in computational fluid dynamics, flow control and aerodynamics, mentored the project from his own research.

“The design project was one of the best experiences I had in the college, because I got to apply what I had learned in class,” said aerospace engineering major Phillip Greenberg. “We had a lot to do, and one of the biggest things I learned was how to communicate a very technical project to people who are not so technically experienced.

“Right now I would be happy to work anywhere I could be innovative for companies in the industry, like Raytheon or Blue Origin.”

Award-Winning Slide Staining


Sometimes trial and error pays off. Ask Team 1427, who took second place in the Raytheon Sensintel Best Overall Design competition at Engineering Design Day 2015.

With off-the-shelf components, Team 1427 developed a more efficient system for microscopic examination of tissue samples. The system allows for testing a sample at three different temperatures.

“The point of thermal control is that instead of running three different tests under three different temperatures, you can run one thermal test across a single microscope,” said team member Chris Sanford.

The project expands on current slide-staining techniques, in which tissue samples are fixed on to a slide using a technique called "heat-fixing." Once that is done, a dye can then be added to stain the sample so that the cells and cell components are easier to view.

Team members, with the help of mentors Chris Donat, Kenyon Kehl and Steven Lei, had several challenges to overcome – like figuring out which materials would make the vest slide base without contaminating the sample.

Marissa Lopez-Pier was in constant...




Safeguarding Aircraft Generators

Congratulations to Team 1420 for winning the Rincon Research Best Presentation Award at Engineering Design Day 2015. The team developed a new type of electromechanical shaft to disconnect an aircraft generator from the engine output in the event of electrical short or bearing failure.

“The purpose is to save the entire generator from complete failure,” said team member Jose Luttmann. Currently, aircrafts do not have such a device. “We’ve been working on this project since last semester from a concept design that we put into practical use.”

“What they have between the aircraft engine and the generator is a called a shear point,” explained team member Ivy Hasman. “The shear point breaks apart the shaft, so that the engine is still spinning with the generator disengaged, but now there is still a broken shaft.”

The new electromechanical shaft disconnect allows the engine to continue providing power to the aircraft without further damaging the generator. The team is confident that their device can be applied to larger aircraft. 

"Because we are students, we were limited to what we can do, but...

Donation from Sturm, Ruger & Co. Enhances Machine Shop Offerings

Engineering senior Rolland Prempeh perfects a component for his senior design project on a mill in the AME machine shop A generous gift of more than $200,000 worth of machining tools from Sturm, Ruger & Co. will bolster the creative capacities and first-hand knowledge of College of Engineering students, most of whom use the the Aerospace and Mechanical Engineering Instrument Shop for their senior design projects.

As aerospace engineering student Rolland Prempeh said, "The machine shop is the heartbeat of our department."
