NWUAV NW-44 Multi-Fuel UAV Engine

NWUAV purpose-built NW-44 multi-fuel engine is designed and built for unmanned aerial systems (UAS), low altitude, long endurance aircraft and portable power generation.

The NW-44 engine is the most easily configurable small UAV engine on the market today. This purpose-built UAV engine will handle aircraft from approximately 18 to 35 kg (40-77 lbs.) depending on mission requirements. The NWUAV engine core and subsystem components alleviate ITAR and end of life concerns and are primed to meet pending FAA Certification requirements.

Typical civilian uses include monitoring climate changes, forest fires and mapping glaciers as well as supporting police, fire, and law enforcement bureaus.
