Purdue-related startup develops high-performance, environmentally clean solid rocket propellant for use in missile and space-launch systems

WEST LAFAYETTE, Ind. – A Purdue-related startup is developing a new rocket fuel formulation that could make rockets used in military and space applications, travel further, carry greater payloads and be safer for the environment.  

Brandon Terry, a Purdue alumnus and postdoctoral research associate in Purdue’s Department of Mechanical Engineering, and Chris Stoker, an Indiana University alumnus, co-founded the company Adranos Energetics to develop the technology to enhance rocket performance.

Stoker said that rocket fuel hasn't changed in the last 60 years and has two major defects: inefficiency and its detrimental effects on the environment.

"Current rocket fuel sources emit toxic hydrochloric acid that damages the environment and corrodes launch equipment, resulting in expensive environmental remediation costs and equipment maintenance costs," he said. "Our fuel combustion process prevents hydrochloric acid from ever forming, completely eliminating the rocket's negative effects."

In addition, Adranos's fuel formulation uses micro-explosive tendencies that produce much higher combustion efficiency and decreased flow losses, causing rockets to go farther while carrying more weight.

"This whole new realm of metallic, micro-explosive fuels has been observed by people but not yet utilized in a propellant formulation. When a rocket is moving forward, the fuel source is often discharged from the rocket plume, meaning the fuel is coming off of the fuel source and not igniting to propel the rocket forward," Terry said. "In current fuel sources up to 10 percent of the fuel is lost, however our fuel causes the previously lost fuel to micro-explode so we harness the full fuel source to propel the rocket forward with more force and at faster speeds."

The U.S. Department of Defense and U.S. allies could use the rocket fuel, Terry said.

"Using our propellant, rockets could fly much farther and with a greater explosive power, keeping soldiers at a greater and safer distance," he said. "Our propellant could not only protect the life of the war fighter by giving him a competitive advantage but also reduce corrosion to the equipment, saving significant amounts of money."

Stoker said the technology could also be valuable in space-exploration applications.

"One of the issues preventing space flight is cost," Terry said. "With our technology we can reduce those costs significantly, enabling space flight and putting more satellites into orbit."

The company is in the lab-scale testing stage and has shown increased performance and elimination of hydrochloric acid in small-scale propellant combustion.

"Right now we are conducting tests to prove that the technology works as the rockets scale in size. We are currently proving functionality and performance characteristics in rocket motors that are three inches in diameter and 15 inches in length, and we will eventually scale to rocket motors that are five inches in diameter and five feet in length,” Stoker said. “Compelling results from these tests could open doors for our fuel to be adopted for use in a variety of space-launch and missile systems." 

Adranos Energetics won the Gold Division of the 29th annual Burton D. Morgan Business Plan Competition at Purdue, receiving $30,000 in funding. The company also placed first in the University of Oregon's 25th New Venture Championship and first in the graduate division of the University of Nebraska-Lincoln's Global New Venture Competition, receiving $25,000 and $10,000, respectively.

Technology used by Adranos Energetics LLC has been licensed through the Purdue Research Foundation Office of Technology Commercialization. Adranos is a member of the Purdue Startup Class of 2016. Purdue has 27 startups based on Purdue intellectual property that were launched in the 2016 fiscal year. A video of the company can be viewed here.

Adranos Energetics is currently utilizing lab space in the Maurice J. Zucrow Laboratories, which is affiliated with the Purdue School of Mechanical Engineering and the School of Aeronautics and Astronautics.

The company has received initial funding from the Purdue Research Foundation, Elevate Purdue Foundry Fund, Air Force Office of Scientific Research, National Defense Science and Engineering Graduate Fellowship, Purdue Forever fellowship and an Air Force Office of Scientific Research Multidisciplinary University Research Initiative contract.

The company is seeking $500,000 to $1 million in additional funding to reach the end of phase two, which would allow the company to prove tactical validation in actual missile systems or in other real-life, large-scale rockets, over the next few years.
