MITRE Employee Shares His Passion for Engineering

by Eidson, William B.

on 9/16/2014 9:17 AM

The tension of the three teams was palpable as the remotely operated underwater vehicle (ROV) approached the sunken sub. One team’s ROV hovered above, providing visual guidance. Another’s had already successfully opened the sub’s hatch. They watched the monitors intently as the deployment motor whirred, propelling the payload into the sub.

Mission accomplished.

“Everyone just screamed and started clapping and singing, ‘We Are the Champions,’” said Dale Delisle, a lead mechanical engineer in MITRE’s National Security Engineering Center, a federally funded research and development center sponsored by the Department of Defense. The payload was a bottle of water, the sunken sub a set of six black milk crates, and the undersea setting a pool. And the three teams were comprised of eight middle-school girls and two boys at the University of New Hampshire (UNH) Tech Camp in late summer. Dale and three other colleagues were using the SeaPerch ROV program to provide students with the opportunity to learn about science, technology, engineering and mathematics (STEM).

"They gained so much pride as engineers," said Dale. "They were nervous in the beginning, but by the end they felt they could do anything."

Professionally, Dale is well-qualified to teach about ROVs. Before MITRE, he worked at the Portsmouth Naval Yard for the Navy. He once dove 2,000 feet down in a deep submergence rescue vehicle.

“You should hear the hull creaking at that depth,” he said. “And for MITRE, I’ve done interesting work all over the world. I want to share my passion for engineering and help students understand that it’s far from dry and dull, but genuinely exciting.”

Dale took a circuitous path to his love of engineering. After two years study to be an electrical engineer, he dropped out of college to join the Army. He served in Desert Storm and ultimately ended up in Germany in communications. After he returned home, he ran a martial arts school for eight years. But he was always strong in math and science and returned to engineering.

“What really thrills me is the application of engineering as much as the theory. I’ll ask the kids as they are sitting in an air-conditioned room, ‘Are you comfortable right now? What if it was 40 degrees outside? Or 90? The air conditioning or heating systems that are keeping you comfortable—and engineers designed them. The same is true for your smart phones, which didn’t even exist ten years ago.’ My goal is to help young people realize how engineering can improve and often impact lives on a massive scale. That a doctor may save one life at a time, but an engineer who does something like figuring out a low-cost water filtration system may save millions.”

In 2008, Dale took a semester-long [unpaid] sabbatical and taught at UNH, including a college-level version of the SeaPerch ROV project that the middle school students did this summer.

“It was more challenging, with tighter restrictions, but essentially the same program. These middle school students had to measure, design, cut, and figure out the systems. We showed them how to waterproof the motor including taping and then potting them in wax. It’s a real challenge to use electricity in water. And this year, they came up with a unique way to push the payload into the sub—they used a motor to accelerate the water around the water bottle to push it in.”

Dale devotes about 80 hours a year to volunteering for STEM programs.

“As the baby boomers retire, they are leaving a significant gap in the fields of science and technology,” he said. “Do any reading about the topic, and you can see the shortfall is a real problem. So I feel it’s important to volunteer for these STEM training programs for the sake of our country and our position as a global leader—but it also does so much for me. It’s revitalizing. It helps me articulate for myself what I do. When I volunteer for these STEM programs, I easily get back as much as I give.”

ISE Faculty Choice Awards

The Mechanical Engineering Faculty Choice Award at the Interdisciplinary Science & Engineering Symposium (ISE) which took place on April 23, 2014, was given to three teams:


The Computationally Efficient Representation of Statistically Described Material Microstructure for Tractable Forming Simulations, a research project done by Nicholas Landry.

Project Advisor: Marko Knezevic

IMG_2413.JPGProject description: Performing microstructure sensitive metal-forming simulations is widely recognized as a computational challenge because of the need to store large sets of state variables related to material microstructure data. My project was to compact these large sets of statistical microstructure material data to smaller, representative statistical distributions using Fourier spectral methods. The objective is to determine the minimum number of microstructure data to accurately represent the material response. This method was proved, using copper, which has a cubic crystal structure and deforms by slip and zirconium, which has a hexagonal crystal structure and deforms by slip and twinning. The conclusions of this study are that this framework of data compaction works for metals with several symmetries and deformation mechanisms.



The Separation Phenomena in Shear Wake Flows Team:
Mike Auger
Douglas Carter
Amanda Makowiecki

Project Advisor: Joe Klewicki

IMG_2403.JPGProject Description: Our team is studying the formation of horseshoe vortices that result from a shear wake flow around a cylinder i.e two different parallel flow velocities that converge at the end of a vertical splitter plate and pass over a horizontal cylinder downstream. The vortices are being investigated over a range of flow velocity combinations and cylinder sizes. The goal is to develop a better understanding of the mechanism by which these vortices form.





Modeling Machining Distortion Using the Crystal Plasticity Finite Element Method, a research project done by Daniel Savage.

Project Advisor: Marko Knezevic


IMG_2388.JPGProject description: Distortion that occurs during machining processes is an expensive problem for the aerospace industry, wherein materials can have a fly-to-buy ratio exceeding 8 to 1. High cost for parts is often due to material loss, to scrap rate, and to time spent developing and implementing machining procedures to circumvent distortion. The hypotheses of this capstone project is that by modeling the last forging operation on a material and subsequent machining passes, an optimized forging and machining procedure can be developed to reduce material scrap, and the time and the quality of method used for circumventing machining distortion can be greatly improved. A combined modeling and experimental strategy is being utilized to develop the tools needed to thoroughly test this hypothesis. The four main tasks of the project have been: 1) A material subroutine to be used in finite element analysis (FEA) was written from the ground up for GPU platforms, achieving over three orders of magnitude increase in speed and allowing tractable multi-scale crystal plasticity simulations; 2) a four-point bending simulation was created as a test case for model validation; 3) the methodology for simulating machining and automating the simulation procedure was implemented in FEA software Abaqus using Python; and 4) the current task, consisting of experimental validation of the model through relaxing the stress state through annealing, performing a four-point bending test, machining a part, and measuring distortion using a computer measurement machine (CMM).

ISE First Place Poster Award

The First Place Poster Award at the Interdisciplinary Science & Engineering Symposium (ISE) which took place on April 23, 2014, was given to:

The Research & Development of WingTip Devices for Hydro-Kinetic Turbines and other Marine Applications team: 
John Brindley and Jesse Shull 
Project Advisor: Martin Wosnik
IMG_2342.JPGProject description: Novel wingtip devices were designed for hydrokinetic turbines in order to avoid biofouling and to reduce or control cavitation and wingtip vortices. A legacy testing apparatus was designed using Solidworks and employed finite element analysis to ensure longevity. The WEBFM (Wingtip Elliptical Base Foil Mount) has an extension piece so that different wingtips can be cheaply manufactured. Multiple devices were designed in both GNU Octave and Solidworks and tested using the open source computational fluid dynamics package OpenFOAM. A novel device coined the SplitTip shows promise in countering the effects of wingtip vortices and is now patent pending. DMLS (Direct Metal Laser Sintering) was provided by TurboCam to create the various wingtip devices. The WEBFM and wingtip devices were assembled and tested in UNH’s HiCAT (High-speed CAvitation Tunnel). Comparison of the HiCAT and OpenFOAM models will be presented.

ISE Student Choice Award

The Mechanical Engineering Department Student Choice Award at the Interdisciplinary Science & Engineering Symposium (ISE) which took place on April 23, 2014, was given to:

The Wave Energy Conversion Buoy Team:
Carl Smith
Joe Henderson
Corey Sullivan 
Project Advisors: Rob Swift and Ken Baldwin

IMG_2229.JPGProject description: The Wave Energy Conversion Buoy (WECB) is a senior design project in the Undergraduate Ocean Projects course for the 2013/2014 school year. The WECB team’s goal is to design and construct a point absorber wave energy device, which will generate electrical power from ocean waves. This point absorber buoy generates power by using the relative motion between two buoys (the middle spar buoy and the follower “donut” buoy) to drive a rack and pinion gear system that in turn spins a generator. The intent of the project is to demonstrate wave energy as a viable source of renewable energy for powering the Shoals Marine Laboratory located on Appledore Island, Isles of Shoals, off the coast of Maine and New Hampshire. The buoy will be tank tested, and implemented for a one-two week period of time in April at a site located off the eastern shore of Appledore Island.
