This paper discusses select design aspects and early testing results for the HELIOS project. The objective of this project was to complete preliminary research and design of a hybrid electric propulsion system for unmanned aerial vehicles. Efficiency models showed that a mechanically additive system would provide the greatest benefits when compared to other additive system designs. Utilizing a clutch-less gearing system to mechanically combine the output power of an internal combustion engine with an electric motor, a 15% increase in fuel efficiency over traditional gas powered UAVs of similar size was projected. Preliminary efficiency tests using a custom-built dynamometer have shown that this model will be satisfactorily accurate. The technology provides also additional operational safety in case of engine failure. Operating the aircraft in electric mode only allows for low noise operation during any phase of the operation. Preliminary testing of the HELIOS system was performed on the 13 ft wingspan aircraft being constructed by students from Daniel Webster College located in Nashua, New Hampshire.

The Hyperion aircraft project was an international collaboration to develop an aerial vehicle to investigate new technologies with a focus on performance efficiencies. A delocalized international team of graduate and undergraduate students conceived, designed, implemented, and operated the aircraft. The project taught essential systems engineering skills through long-distance design and manufacturing collaborations with multidisciplinary teams of students located around the world. Project partners were the University of Colorado Boulder, USA, The University of Sydney, Australia, and the University of Stuttgart, Germany. The three teams are distributed eight hours apart; students can relay select work daily so that developments can “Follow-The-Sun”. Select components are manufactured and integrated both in Stuttgart and Colorado, giving the students an opportunity to learn multifaceted design tactics for manufacturing and interface control. Final flight testing was conducted by the global team in Colorado during the month of April 2011.

A delocalized international team of Graduate and Undergraduate students conceive, design, implement, and operate a 3 meter wingspan aircraft with the intent to investigate numerous new ‘green’ aircraft technologies. The project, known as Hyperion, teaches essential systems engineering skills through long-distance design collaborations with multidisciplinary teams of engineering students located around the world. Project partners are the University of Colorado at Boulder, USA, the University of Sydney, Australia, and the University of Stuttgart, Germany. The teams on three continents are distributed 8 hours apart; students can relay select work daily so that progress can “Follow The Sun (FTS).” As a result three workdays are packaged in one 24 hour period. The student teams operate as a single, independent entity; structuring themselves as a simulated industry operation. Thus, project management and systems engineering principles are learned through a real-world design and deliver experience. The project also teaches delocalized manufacturing: select components are manufactured by each team and integrated both in Stuttgart and Colorado, giving the students an opportunity to learn multifaceted design for manufacturing. The project incubated many problems which lead to mitigation techniques for global collaboration as well as generating a better educated workforce to enter modern industry.Copyright

The Hyperion project is a global/international collaboration to conceive, design, implement, and operate an aerial vehicle platform investigating numerous new technologies focusing on increasing capabilities and reducing emissions. The project also provides a research and learning opportunity to cdio a system with delocalized global teams of students.

Student engineering teams collaborated across three international universities to develop a 3 m wingspan unmanned aircraft in a single academic year. This aircraft, named Hyperion, is inspired by the NASA/Boeing X48-B blended wing body, and serves as a test platform for high efficiency aerodynamics and propulsion. The design concept includes a novel hybrid gas-electric propulsion system developed by a University of Colorado spinout company, Tigon EnerTec. The aircraft features a high-lift blended-wing body design, composite materials, and advanced flight controls, and was successfully flight tested in the Spring of 2011. Students at the University of Colorado, the University of Stuttgart, Germany, and the University of Sydney, Australia, benefited greatly from the multi-national design and delocalized manufacturing, which was conceived to simulate modern industry practices. Hyperion’s unique architecture and advanced subsystems establish novel technologies that can be incorporated into UAV, general aviation, or commercial markets.

Student engineering teams developed a 3 m scale model aircraft, named Hyperion, inspired after the NASA-Boeing X48-B blended wing body to use as a test bed for advanced technical studies. The design concept includes a novel hybrid gas/biodiesel-electric power train as a green aircraft technology. The hybrid propulsion system allows for new concepts of operation in unmanned vehicles as it can operate in an internal combustion-only, electric-only, or hybrid mode. The aircraft is designed through a collaboration of 3 international universities: the University of Colorado Boulder, the University of Sydney, AUS, and the University of Stuttgart, GER. The Hyperion aircraft has a blended fuselage and wing to utilize advanced aircraft design and aerodynamic efficiency. The flying wing architecture is a fuel efficient platform to demonstrate the latest developments in ‘green’ aircraft technology. The optimal design requires a full systems engineering analysis, including aerodynamic and structural analysis of the vehicle; design of the flight mechanics, navigation, and control systems. The vehicle is fabricated primarily from composite materials. Hyperion’s unique architecture and advanced subsystems establish novel technologies that can be incorporated into UAV, General Aviation, and larger aircraft.Copyright

A case study is presented demonstrating the logistics and synergies behind starting a university spin-out company and the advantages of spawning entrepreneurship out of an academic environment. A recent start-up company, TIGON Enertec, Inc., has emerged out of the University of Colorado (CU) from the collaboration of multiple incubation programs with the vision to increase the success-rate of university spin-offs. Several timely developments, organizations, and funding opportunities were enabling this start-up; A) NASA funds on workforce development. B) The University of Colorado who created the Renewable and Sustainable Energy Institute (RASEI). C) The Center for Space Entrepreneurship (e-Space, Inc.), a not-for-profit organization recently formed as a partnership of the University of Colorado, a national leader in aerospace engineering education, and SpaceDev, Inc. a leading entrepreneurial space company. All three components served as pillars for the start-up. The creation of such a supportive environment, which has helped the TIGON team begin their venture, may serve as potential model for university and small business relationships.
