Excited chatter and bright orange tassels filled the back halls of the Frank Erwin Center May 16th at 6 p.m. as soon-to-be graduates scurried to form alphabetical lines before making the grand entrance into the spring 2008 Cockrell School of Engineering commencement ceremony. For many students, graduation day is a long road from their first year, but for Robert B. Tenison this day was 66 years in the making.
When asked why he petitioned to graduate with the class of 2008, the 84-year old resident of Abilene, Texas responded, “I have always been a proponent of education. In talking to my grandkids, I thought, this is a silly situation. Here I am preaching to them to get a degree and I don’t have one myself!” Originally from Houston, Texas, Mr. Tenison first began classes at UT in 1942 in the new Department of Aeronautical Engineering. There was not a published curriculum and students worked with a faculty advisor to determine classes. As a student, Mr. Tenison was president of SAE Fraternity, tried out for the football team, and enlisted in the U.S. Navy. His military duties interfered with his student status, relocating him to the Olathe, Kansas Airbase.
When the war was over, Mr. Tenison returned to UT for summer school thinking this would complete the requirements for his degree. “I thought that I had the degree; I even bought my ring,” said Mr. Tenison. By 1946, however, there was a published degree plan and some of the courses had changed. Mr. Tenison left school for the last time. “I was out of money and I needed to make a living,” explained Mr. Tenison. “So I decided to go into the oil business, taking a job at $95/month. I have been in the oil business for over 55 years now.” “I would have liked to have the degree, but it was not critical to my work,” said Mr. Tenison. Over the last 62 years, Mr. Tenison has worked in all facets of the oil business, eventually starting Tenison Oil Company in 1988. He lost his first wife Anna Jo Tenison after a lengthy battle with ALS and married Willie Mae Tenison. Together, he and Willie Mae have five children, ten grandchildren, and two great-grandchildren.
In early 2008, Mrs. Tenison called the University to check the actual status of Mr. Tenison’s degree, hoping he could still complete needed coursework to graduate. Since the Aeronautical Department no longer exists, his information was forwarded to the Aerospace Engineering Department. After a thorough review of his course work and one very reasonable course substitution, the registrar determined Mr. Tenison had indeed earned his 1946 Aeronautical Engineering degree. He was added to the list of graduates for 1946, becoming the 22nd graduate at UT in Aeronautical Engineering.
In a borrowed cap and gown from the Cockrell School of Engineering, Mr. Tenison joined the rest of the graduates seated before Dean Streetman and Cockrell School of Engineering faculty for the graduation exercises. In the audience were his wife, Willie Mae, his children, and two grandchildren. First to cross the stage, thunderous applause erupted from the student population as they realized the face on the Jumbo Tron was that of an 84-year-old man. With degree in hand, Mr. Tenison waved to his new fans and exited stage left, thus ending his education, embraced in a spontaneous standing ovation and cheers of thousands.

The UT Department of Aerospace Engineering and Engineering Mechanics scored impressive 2nd and 4th place wins against almost 70 other university teams in the American Institute of Aeronautics and Astronautics Design-Build-Fly (DBF) Competition held in Wichita, Kansas 19-21 April, 2008. Holding down the #1 and #3 spots was Oklahoma State University. The UT HornWorks DBF Team under the able leadership of Ivan Kung, class of ’08 from Austin, accepted a $1500 2nd place cash award on behalf of UT. The Orange Bullet UT team led by Martyn Hunt, class of ’08 from The Woodlands and Aberdeen, Scotland took placed 4th in the competition. Since the DBF competition started in 1996, only 2 universities have had both their teams finish in the top four.
The UT DBF teams are made up entirely of undergraduates and are self organized and managed. Participation is voluntary. Team leads are elected and students are organized much like an industry design team. Typical organizational responsibilities include Aerodynamics, Propulsion, Structures, Vehicle Design and Manufacturing. The teams are advised by a student strategy team led by Odin Creel, class of ’08 from St. Augustine, FL.
The 2nd place Hornworks team consists of 23 students including 7 freshman, 5 sophomores, 3 juniors and 7 seniors. In addition to Team Lead Ivan Kung, key members of the leadership team include Stephan Greening, class of 08 from Austin, Daren Wang, class of 09 from Dallas, Jeff Chu class of 08 from Houston, Jason Fortner class of 09 from Cary, NC and Vishnu Jyothindran class of 10 from Austin. Other team members include Joel Chapa, Jason Lavine, Akash Gandhi, William Duong, Charles Gilbreath, Elisa Gravis, Matthew Jones, Tausiq Ahmed, Garrett Mosely, Nathan Wu, Krystal Stewart, May Ann Li, Tarique Rahman, Alex Cheng, Charlotte Bryan, Craig Dorsey, and Paul Wedholm.
The 4th place Orange Bullet team consists of 14 students including 3 freshman, 4 sophomores, 1 junior and 5 seniors. In addition to Team Lead Martyn Hunt, key members of the leadership team include Ty Brockhoeft, class of ’08 from Austin, Brady Lotz, class of ‘08 from Grand Prairie and Matias Soto, class of ’08 from Chihuahua, Mexico. Other team members include David Vargas, Michael Skyler Lawson, Najek Haq, Justin Kizer, Andres Perez Segura, Barton Starnes, Jeremiah Bracy, Andrew Pritchard, Seve Rizo Patron and Joaquin Herrera.
Other top teams competing in 2008 were the University of Colorado – Boulder (#5), Wichita State University (#6), Massachusetts Institute of Technology (#7 and #19), University of Southern California (#8), Istanbul Technical University (#9) and Georgia Tech (#10).
The American Association of Aeronautics and Astronautics (AIAA) DBF competition sponsored by Cessna Aircraft Company and Raytheon Missile Systems is considered by most aircraft design professionals to be the premier international aircraft student design competition. Every year AIAA unveils a unique new design challenge against which the best and brightest of the world’s future aerospace engineers team up to not only design, but also build and fly a winning concept. The 2008 competition required that student teams design an electric power unmanned aircraft system (UAS) capable of carrying a payload of up to 14 partially filled half-liter water bottles or four US half-size clay bricks or various combinations thereof on two flights around a predetermined course. Equally challenging was another flight with no payload that had to be completed with an absolute minimum number of batteries. The combination of the two missions challenged the student teams to deal with important trade-offs involving heavy lift and high efficiency similar to those faced in the real world of air system design. Equally challenging was the fact that the design mission changes every year and every team has to make a fresh start, albeit based on lessons learned from previous years (another real world fact of life).
UT Aerospace Engineering and Engineering Mechanics (ASE/EM) would like to express its appreciation to AIAA, Cessna, Raytheon and other DBF supporters for their important contributions to providing the next generation of Aerospace Engineers (worldwide) with a real world competitive (but constructive) environment focused on education that will help us all live in peace and prosperity.
The seed for success for the UT DBF program was planted by Dr. Mark Maughmer, a visiting professor from Penn State University. Invited to UT by Dr. Robert H. Bishop, ASE-EM Chairman, in 2006, Dr. Maughmer made a series of insightful recommendations for moving our DBF program forward. Among his recommendations was the importance of providing a hands-on four year aerospace design experience versus the traditional 4th year capstone design focus. With a shared commitment to provide opportunities for hands-on aerospace systems design experience, Dr. Bishop has put the full support of the department behind the DBF teams. Dr. Maughmer’s son Mark joined the UT staff shortly thereafter and has been helping the UT DBF team implement the concept ever since. Mark has an Aerospace Engineering degree from Penn State and has been a life-long sailplane and radio controlled model aircraft designer and builder.
Dr. Bishop, Dr. Chaput, and the Design, Build, Fly teams would like to extend their gratitude to the ASE alumni, external advisory committee members, and friends for their continual support. All the external assistance is absolutely invaluable.

The recently formed Longhorn Rocket Association (LRA) is proud to be taking off to a great start. The purpose of LRA is to provide a hands-on opportunity for undergraduates in the Department of Aerospace Engineering to become familiar with designing, building, and launching amateur rockets.
The rocket group was originally started in spring of 2007 and is the only rocketry group at UT. Last semester, LRA became an official group of the Department. In November, they held their inaugural launch at Pickle Research Center. Over 20 people, including aerospace engineering students, advisors, faculty, and staff, showed up for the historic first launch, in which the group launched over 10 model rockets that they built themselves throughout the semester. The rockets ranged from 3 inches tall to one six-foot tall rocket: The Mean Machine. One of the most fascinating launches was the Comanche 3, which is a three stage rocket. Some of the rockets flew as high as 1,500 feet and each rocket came back to the ground with either parachutes or streamers that deployed from the nose cone. After each launch, the group sent out “search parties” to find the rockets that the wind carried away during landing. Despite strong winds and a bit of drizzle, the group had a very successful first launch and all members and spectators had a great launch experience. Over the past couple of months, over 30 students ranging from freshmen to seniors have met Friday evenings and Saturday mornings in the Air Systems Design Lab for their weekly “Rocket Builds”.
Last semester they started with model rockets in order to orient everyone who was new to rocket building. With their own tools, materials, glue, and hard work, they constructed multiple rockets. This semester, the group is moving on to more advanced projects. They will be building their own fiberglass rockets, made almost entirely from scratch. The rocket bodies and fins will be constructed of fiberglass, while the nose cones will be produced by rapid prototyping. The group will be involved in every stage of the process, from designing the nose cones in SolidWorks, to creating the parachutes and recovery systems, to incorporating electronic instrumentation. In addition to building the fiberglass rockets, the group will participate in a model rocket competition in April. Two of the senior rocket group members are also working on rocketry research projects which will ultimately benefit the group’s future. The members are also working on becoming certified members of the National Association of Rocketry (NAR). In addition, LRA recently volunteered at UT’s open house, Explore UT, on Saturday, March 1, where they built model rockets with children from the Austin area.
In the upcoming semesters, the Longhorn Rocket Association has set many goals. This includes fiberglass rocket competitions, competitions amongst themselves, with other universities, and hopefully a competition where the group will travel out of state for a NAR competition. The group also plans to launch a “Cricket Sat” during one of their upcoming launches. They also hope to test their rocket engines at Pickle Research Center, build high powered rockets, and calculate and build reusable rocket engines. With the efforts of all of the new and dedicated members, and with the help of Dr. Varghese as their sponsor and Dr. Hayes as their Advisor, the group has come far. The members are excited about the opportunities that lay ahead and are proud of the distance the group has come in such a short time period.

Stephanie Wilson graduated from UT Austin with a master’s degree in aerospace engineering in 1992 after being recruited by Dr. Robert Bishop, former chair of The University of Texas at Austin’s Department of Aerospace Engineering and Engineering Mechanics. Her master’s thesis “Substructural Controller Synthesis: A Comparison of Two Methods” drew upon both of her advisors: Dr. Bishop’s expertise in planetary exploration with emphasis on spacecraft guidance, navigation and control; and now retired Aerospace Engineering Professor Dr. Roy Craig’s expertise in structural dynamics.
Later, after she was accepted into NASA’s astronaut training program, she received the Outstanding Young Texas Ex award in 2005. The crew of space shuttle Discovery tested new equipment and procedures that increase the safety of space shuttles during the STS-121 mission to the International Space Station. It also performed maintenance on the space station and delivered more supplies and cargo for future station expansion. Prior to the trip, Wilson described some of the mission’s cargo: “We are bringing to the space station crew a variety of experiments. We have a -80° laboratory freezer that they will use to cool samples; we have a European cultivation module that they will use for their experiments; we are pre-positioning an oxygen generation system that will be used for future crews, and we are bringing them a new, Common Cabin Air Assembly for a heat exchanger in the laboratory. The old one has failed and they’ll need to replace that. We have food and clothing for them as well, and hopefully a surprise or two will be packed in there.”
Selected by NASA in April 1996, Wilson reported to the Johnson Space Center in August 1996. Wilson has been a Mission Control prime communicator with on-orbit crews and has had technical responsibilities related to space shuttle main engines, external tank and solid rocket boosters.
Prior to NASA, she worked with Martin Marietta Astronautics Group and the Jet Propulsion Laboratory.

On Nov. 11, 2009, Lockheed Martin presented a check to The University of Texas at Austin in the amount of $95,390, of which $50,000 will support two UT aerospace engineering student projects: the Small Autonomous Rover and the Longhorn Rocket Association. These projects provide critical hands-on experience for aerospace students as they apply classroom theory to real-world challenges. The department deeply appreciates Lockheed Martin’s continued support.
The Horizon Rover Unmanned Autonomous Vehicle project, advised by Professor Robert H. Bishop, has been under development for several years by undergraduate and graduate ASE/EM students. The objective is to develop autonomous obstacle avoidance technologies applicable to a wide range of vehicles types, from autonomous planetary surface rovers to UAS. The UT rover technology is now in its second generation with plans to improve the overall design in a third generation. Key technologies of the current generation include optimal path planning, dynamic obstacle avoidance and trajectory management. The Horizon Rover capabilities are being expanded to surface celestial navigation by fusing heterogeneous sensors suite including a star tracker, LIDAR imager, inertial measurement unit, GPS (for Earth applications), and a variety of sensors for measurement for sensing wheel velocities and heading.
The Longhorn Rocket Association (LRA), currently advised by Professor Charles Tinney, was founded in Fall 2007. In the early years of its inception, LRA members spent most of their time building hobby rockets from kits. Since then, students have become exposed to the design process and are participating in research about materials, aerodynamics, and building methods. Students are also being introduced to engineering skills such as performing trade studies and writing technical proposals. In the Spring of 2009 the LRA reached a new milestone when members designed and built two high powered amateur rockets. Their next goal is to design a rocket expected to reach an altitude of 100,000 ft (19-20 miles). The hope is that in future years the LRA will be able to collaborate with other aerospace groups like the Texas Spacecraft Lab (TSL) and carry payloads such as the picosatellites being built in the TSL.

Dear Alumni and Friends,
Warm greetings from W.R. Woolrich Laboratories! When I stepped in as the new chair of Aerospace Engineering and Engineering Mechanics, it did not take me long to realize that alumni play a critical role in maintaining the excellence of our department and I am most grateful for this support.
With state tax dollars covering only 17 percent of the Cockrell School’s annual budget, alumni support is more important than ever. That is why I am asking our alumni to meet the challenge of moving from 8 percent alumni giving in 2009 to 10 percent in 2010! And although I am not an alum, I have made my own gift to launch this campaign.
Gifts from alumni fund project-based learning that gives students hands-on experience in applying classroom theory to solve real-world challenges. Each week students come to my office asking for funding for their innovative projects. Below are a few of their requests — requests that will be difficult for me to grant without greater alumni support.
• Women in Aerospace Leadership Development (WIALD) needs funding to design and launch a research package (including a camera, altimeter and transducer) that will launch aboard Fredericksburg High School’s Red-Bird-12 ballistic/hybrid rocket. The members of WIALD are committed to recruiting more women into aerospace engineering, and believe interacting with high school students is a first step.
• The Longhorn Rocket Association needs additional funding to design and launch a rocket to break the space barrier (100,000 feet or 19-20 miles). Once the students reach that milestone, their next goal is to carry a payload, such as the picosatellites students are building in the Texas Spacecraft Lab (TSL). Compact, lightweight and relatively inexpensive, picosatellites are a wonderful way to introduce students to the real-world problems associated with building flight-capable hardware.
The stated goals of these projects are just the beginning. Our ultimate goal is to create engineering leaders who will make a difference in the world.
Members of the Longhorn Rocket Association
Future leaders like Alexis Avram benefited from Professor Cesar Ocampo’s outreach as a high school student and she began studying orbital mechanics, electrodynamics, and momentum exchange tethers. Alexis is now an aerospace engineering sophomore and an active member of the Longhorn Rocket Association. She is also planning an internship at NASA — you can read more about Alexis here.
If 200 ASE/EM alumni each donate $1,000 this year, we can fund our current student projects and know we have the funds to launch next year with real momentum. To demonstrate our personal commitment my wife Mae and I have donated $1,000, and I invite you to join with us to contribute at the most generous level possible. Remember that every gift, no matter its size, makes a real difference during these tough economic times. Our goal is 10% participation in 2010! Won’t you join us?
Best wishes,
Philip L. Varghese
