A small-scale jet engine compact enough to fit on a tabletop is helping to make the future of aviation more sustainable, according to NASA engineers currently involved in tests that could help pave the way toward new aircraft propulsion systems of the coming decades.
The DGEN380 Aero-Propulsion Research Turbofan (DART) is less than 4.5 feet in length, making it half the size of engines on moderately sized aircraft, and NASA engineers are now using the miniature engine to help to reduce costs associated with using a full-sized jet engine for research and testing purposes.
