CU student’s project UAV to “shake the ground” of rocket research
Feb 23rd
jetting toward commercialization
Propulsion by a novel jet engine is the crux of the innovation behind a University of Colorado Boulder-developed aircraft that’s accelerating toward commercialization.
Jet engine technology can be small, fuel-efficient and cost-effective, at least with Assistant Professor Ryan Starkey’s design. The CU-Boulder aerospace engineer, with a team of students, has developed a first-of-its-kind supersonic unmanned aircraft vehicle, or UAV. The UAV, which is currently in a prototype state, is expected to fly farther and faster — using less fuel — than anything remotely similar to date.
The fuel efficiency of the engine that powers the 50-kilogram UAV is already double that of similar-scale engines, and Starkey says he hopes to double that efficiency again through further engineering.
Starkey says his UAV could be used for everything from penetrating and analyzing storms to military reconnaissance missions — both expeditions that can require the long-distance, high-speed travel his UAV will deliver — without placing human pilots in danger. The UAV also could be used for testing low-sonic-boom supersonic transport aircraft technology, which his team is working toward designing.
The UAV is intended to shape the next generation of flight experimentation after post-World War II rocket-powered research aircraft, like the legendary North American X-15, have long been retired.
“I believe that what we’re going to do is reinvigorate the testing world, and that’s what we’re pushing to do,” said Starkey. “The group of students who are working on this are very excited because we’re not just creeping into something with incremental change, we’re creeping in with monumental change and trying to shake up the ground.”
Its thrust capacity makes the aircraft capable of reaching Mach 1.4, which is slightly faster than the speed of sound. Starkey says that regardless of the speed reached by the UAV, the aircraft will break the world record for speed in its weight class.
Its compact airframe is about 5 feet wide and 6 feet long. The aircraft costs between $50,000 and $100,000 — a relatively small price tag in a field that can advance only through testing, which sometimes means equipment loss.
Starkey’s technology — three years in the making at CU-Boulder — is transitioning into a business venture through his weeks-old Starkey Aerospace Corp., called Starcor for short. The company was incubated by eSpace, which is a CU-affiliated nonprofit organization that supports entrepreneurial space companies. Starkey’s UAV already has garnered interest from the U.S. Army, Navy, Defense Advanced Research Projects Agency and NASA. The acclaimed Aviation Week publication also has highlighted Starkey’s UAV.
Starkey says technology transfer is important because it parlays university research into real-life applications that advance societies and contribute to local and global economies.
It also can provide job tracks for undergraduate and graduate students, says Starkey who’s bringing some of the roughly 50 students involved in UAV development into his budding Starcor.
“There are great students everywhere, but one of the reasons why I came to CU was because of how the students are trained. We definitely make sure they understand everything from circuit board wiring to going into the shop and building something,” said Starkey. “It makes them very effective and powerful even as fresh engineers with bachelor’s degrees. They’re very good students to hire. That’s a piece that I’m interested in embracing — finding the really good talent that we have right here in Colorado and pulling it into the company.”
Starkey and his students are currently creating a fully integrated and functioning engineering test unit of the UAV, which will be followed by a critical design review after resolving any problems. The building of the aircraft and process of applying for FAA approval to test it in the air will carry into next year.
Starkey’s continuing fascination with speed first began to burn inside of him when he visited Kennedy Space Center at the age of 5.
“When I teach I tell my class, ‘If it goes fast and gets hot, I’m in it.’ That’s what I want to do. There needs to be fire involved somewhere.”

CU students reach big carbon neutrality goal
Feb 16th
FACILITIES REACH CARBON NEUTRALITY
The University of Colorado Student Government has reduced the net emissions of greenhouse gases, or GHGs, from its student-run facilities to zero after committing in 2007 to reach carbon neutrality.
CUSG operates three large CU-Boulder facilities including the University Memorial Center, Student Recreation Center and Wardenburg Health Center.
“We are very proud of this accomplishment,” said CUSG Vice President Carly Robinson. “It’s a reflection of our sustainability-minded campus community and the impressive resources we have on hand to be more environmentally friendly, and even save money, by implementing green strategies.”
CU-Boulder students will gather for a “Getting to Carbon Neutrality” forum on Friday, Feb. 17, from 10 a.m. to 2 p.m. in the Aspen Room of the University Memorial Center. They will discuss the campus’s carbon neutrality achievements and remaining challenges with input from a panel of CU staff. The event is open to CU students but requires pre-registration at http://ecenter.colorado.edu/carbonneutrality.
More than 9,000 metric tons of GHG emissions attributed to operating the student-run buildings have been eliminated through renewable energy generation, energy conservation measures and carbon-offset strategies implemented by CUSG. Carbon neutrality was reached even as square footage and usage of the facilities increased in recent years.
CUSG partnered with Facilities Management to install additional solar panels on CU facilities that contribute roughly 72,000 kilowatt-hours of energy per month to the electricity grid — enough to power about 80 houses. This renewable energy generation replaces a portion of the energy generated by traditional systems that emit GHGs.
CUSG buildings also have been renovated with better insulation and sealing technologies, more efficient lighting and windows. These upgrades reduced the buildings’ total energy consumption by nearly 15 percent over the last five years.
CUSG also has worked with Colorado communities on carbon reduction projects as a way to offset GHG emissions from CUSG buildings. The projects provide educational, economic development and social equity benefits for the state.
One of the projects includes solar thermal system installations, used to heat water, for low-income housing in Loveland, Colo.
Two years ago, the CUSG helped support the installation of a system that converts methane gas from the Larimer County Landfill in Fort Collins, Colo., into energy. Methane gas is a potent GHG emission.
Recently, CUSG contracted with Native Energy — a carbon offsets program provider — to support a novel kiln system used by Commercial Brick Corp., an Oklahoma brick manufacturer. The kiln system is powered by methane gas captured from a nearby landfill. It prevents methane emissions and replaces fossil fuel use. The company, which will participate in the Feb. 17 forum, provides 200 jobs and produces 144 million bricks per year sold in 15 states.
The CU Environmental Center coordinated the carbon neutrality effort. The center administers grants and loan programs within CUSG facilities that have helped fund energy conservation projects, delivering over $1.6 million in energy cost savings for CUSG over the last five years while driving down GHG emissions.
CU Boulder’s video game design research catches fire with students
Feb 15th
to continue video game design research
The University of Colorado Boulder exceeded its own researchers’ expectations with its iDREAMS Scalable Game Design Summer Institute, and that success has been rewarded with a new $1.5 million grant from the National Science Foundation. CU-Boulder researchers are tracking how video game design engages students in computational thinking and STEM simulation design.
STEM simulations are computer programs that model natural and social phenomena, such as how a forest fire spreads from tree to tree. Students design these simulations to learn science, technology, engineering and mathematics, or STEM.
The new NSF-funded Computational Thinking for Teaching Computing grant to computer science Professor Alexander Repenning and co-investigators Kris Gutiérrez and David Webb from the School of Education, will build on previous work the team did on video game design as a motivational tool for computer science education.
That project, called iDREAMS, involved more than 100 teachers and over 8,000 students producing more than 10,000 games and STEM simulations. The project started in Colorado but quickly expanded to Alaska, Ohio, Oregon, South Dakota, Tennessee, Texas and Wyoming where it gave teachers the tools and support needed to take the video game design curriculum into their classrooms. Participation far exceeded initial projections for the iDREAMS research project of about 40 teachers and 1,200 students over three years.
The curriculum, as taught through the Scalable Game Design Summer Institute on the CU-Boulder campus during the past three summers, was found to be highly effective across a wide spectrum of communities, including technology hubs, urban/inner city, rural and remote Native American communities.
The research team was encouraged by the extraordinarily high levels of participation and motivation, especially for girls and underrepresented students: 45 percent of participants were girls and 56 percent were underrepresented minorities. Motivation, expressed by a willingness to take more game design classes, was determined to be 74 percent for boys, 64 percent for girls, 71 percent for white participants and 69 percent for minority students.
In the new project, student performance data using measures of computational thinking will be integrated to further analyze how video game design helps students reason and learn STEM content. The performance data will be used to enhance the Scalable Game Design curriculum and professional development opportunities for teachers.
“I am extremely excited to see the enormous energy of students and teachers involved in the Scalable Game Design project,” said Repenning. “They have shown that it really is possible to bring computer science education to public schools and integrate it into the curriculum. The Scalable Game Design curriculum includes problem solving, logical thinking skills and sophisticated math and science concepts highly relevant to STEM and computer science education.”
CU-Boulder will again host its popular Scalable Game Design Summer Institute for K-12 teachers this summer, June 4-10, as part of its long-term efforts to improve and broaden participation in computer science education.
“We now want to analyze the impact of the research on students’ motivation and what they are learning, continuing the success of the iDREAMS project,” said Webb. “With the new grant, we can build up more robust research instruments that can be used for computer science education. We will continue to be very intentional regarding our research of particular populations and will be broadening the scope of groups studied.”
Project partners include AgentSheets Inc., the Computer Science Teachers Association, the National Center for Women & Information Technology, the Shodor Foundation and SRI International.
