NASA taps Tennessee Tech-led aerospace engineering research team to develop electric-powered commercial aircraft
Five universities and three companies will collaborate on NASA’s long-term goal of
                                       zero-emission air travel while creating opportunity for aerospace workforce development
Tech faculty and student researchers are shown in the university’s Propulsion, Power,
                                       and Thermal Systems Laboratory which will lead a team of seven additional universities
                                       and industry partners in the CarbonLess Electric AviatioN (CLEAN) as part of NASA’s
                                       University Leadership Initiative program. Left-to-right: Faculty members Ahmad Vaselbehagh,

NASA has selected Tennessee Tech University engineering researchers to lead a team
                                 of universities and industry partners to help solve one of aviation’s key challenges
                                 for the future of commercial air travel: zero-emission aircraft by 2050.
With an estimated budget of $8 million, the CarbonLess Electric AviatioN (CLEAN) project
                                 is led by Rory Roberts, Ph.D., associate professor of mechanical engineering and head
                                 of the Propulsion, Power and Thermal Systems Laboratory at Tech. He is joined by two
                                 other Tech faculty members, Bruce Jo, Ph.D., associate professor of mechanical engineering
                                 and Ahmad Vaselbehagh, Ph.D., assistant professor of mechanical engineering. Additional
                                 team members include Tennessee State University, The Ohio State University, University
                                 of Dayton, University of Washington – Bothell, Boeing Research & Technology, Raytheon
                                 Technologies Research Center, and Special Power Sources.
NASA announced the funding last week under its University Leadership Initiative in
                                 the agency’s Aeronautics Research Mission Directorate, which is in final negotiations
                                 with teams for funding up to four years. “The University Leadership Initiative is
                                 an integral part of our research portfolio,” said Bob Pearce, associate administrator
                                 for the Aeronautics Research Mission Directorate at NASA Headquarters in Washington.
                                 “The multidisciplinary teams are directly contributing to our priorities and even
                                 leading the exploration of solutions beyond our current portfolio.” 
Aerospace and aviation agencies and airlines around the globe have set an ambitious
                                 goal of reaching net-zero emissions by 2050 to reduce the climate impact of commercial
                                 air travel, requiring the development of next-generation aircraft. But electrifying
                                 passenger planes like a Boeing 737 is very challenging, Roberts said.
“The energy needed for take-off alone is the electrical equivalent of powering 6,000
                                 homes. There just isn’t going to be a battery that can do that, so you have to think
                                 out of the box and start thinking about the entire aircraft and how to accomplish
                                 that. Huge technological breakthroughs are needed across all these systems to develop
                                 electric flight,” Roberts said.
That’s where CLEAN comes in. Roberts pulled together the CLEAN team of university
                                 researchers with expertise in the various systems and components needed to start designing
                                 an entire aircraft. They will specifically explore a preliminary design for an electrified,
                                 150-passenger aircraft that uses an ammonia-based integrated propulsion, power, and
                                 thermal management system.
“We’re at a point now where we can bring all this research together to design an aircraft,
                                 with the goal of bringing it to market one day,” Roberts added. 
The innovation the team and the University Leadership Initiative will bring to the
                                 aerospace industry extends beyond technology to the education of a future workforce,
                                 according to NASA. 
“This multidisciplinary approach enables the lead teams to partner with others, including
                                 student populations who are underrepresented or have not been involved before in aviation
                                 research,” said Koushik Datta, University Leadership Initiative project manager. “As
                                 we look to future growth in Advanced Air Mobility and an increasing emphasis on creating
                                 truly sustainable aviation, it’s important we involve today’s students in helping
                                 us solve tomorrow’s challenges.” 
The CLEAN team will directly employ 98 undergraduate and graduate students as researchers
                                 across the five universities, with 58 opportunities at Tech alone, according to Roberts.
                                 That’s good news for Tech undergraduate students, as the aerospace concentration in
                                 the mechanical engineering program is rapidly growing.
“Aerospace continues to expand in Tennessee and Tech is poised to support it,” said
                                 Joseph C. Slater, dean of the College of Engineering at Tennessee Tech. “When federal
                                 agencies invest in university-industry partnerships conducting innovative and disruptive
                                 research, there is both a technological impact and workforce development impact. Our
                                 students will learn the skills and future technologies the aerospace industry will
                                 depend on as they develop next-generation aircraft, and that has enormous potential.”
