Smaller and More Powerful Engine Promises Increased Flight Endurance for Military and Commercial Drones

LiquidPiston Inc., an advanced internal combustion engine technology company, will be presenting for Starburst Accelerator’s Selection Committee in Israel on Wednesday, March 7th. The invitation-only event brings together highly disruptive companies in the aerospace industry to present to representatives from global and local aerospace corporations, defense industry officials, venture capitalists and leading university faculty.

LiquidPiston has reimagined combustion engines with a platform that can run on multiple fuels, including diesel, jet fuel, and gasoline, using an optimized thermodynamic cycle and a new rotary engine architecture. This architecture involves only two primary moving parts, a shaft and a rotor, and corrects the major performance, sealing, and lubrication weaknesses of previous rotary engines such as the Wankel. The ‘X’ engine is fuel-efficient enabling greater than 50 percent increases in flight endurance. Furthermore, the architecture significantly reduces engine vibration, noise, and heat output, which minimizes engine impact on ISR equipment and UAV heat, noise and EMI signatures. The lightweight rotary ‘X’ engine is capable of achieving compression ignition in a single stage at a weight of just 1/10th of typical diesel-fueled, piston engines.

“We’re excited to present at Starburst Accelerator’s Selection Committee conference in Israel and share our disruptive new propulsion solution with leaders in the UAV and broader aerospace industry,” said Alexander Shkolnik, CEO and Founder of LiquidPiston. “As the UAV space grows into a $50B-plus market by the mid-2020’s, we believe LiquidPiston’s technology will help UAV manufacturers and operators reimagine unmanned flight possibilities.”

LiquidPiston has developed a range of advanced internal combustion engine prototypes, initially focusing on small engines from 5HP - 40HP. Its 5HP X-Mini is a fit for most Group 2 UAVs, while its larger 40HP X4 engine is a fit for most Group 3 UAVs. All of LiquidPiston’s engines provide power-to-weight and fuel efficiency advantages that enable improved payload capabilities and increased mission flight duration.

The company’s appearance at Starburst’s Israel event comes on the heels of growing UAV industry recognition and interest in LiquidPiston’s propulsion solution by UAV manufacturers and operators. In November of last year, the company took home the top prize at the Association for Unmanned Vehicle Systems International’s (AUVSI’s) NOVUS Unmanned competition in San Francisco. LiquidPiston was also selected to present at Starburst Accelerator’s U.S. Selection Committee conference held in San Diego in December and was previously recognized by Lockheed Martin as the Grand Prize Winner of its Sikorsky Innovation Challenge.
