Northwest UAV begins manufacturing and parts procurement for their NW-88 Multi-Fuel Twin-Cylinder UAV Engine

With a prototype completion date set for beginning of May 2018, Northwest UAV has completed design work and has begun prototyping their new NW-88 multi-fuel twin-cylinder engine. Using design elements from their internationally deployed NW-44 multi-fuel engine, the NW-88 engine system is set to offer the reliability and efficiency of the NW-44 to a new category of aircraft.

McMinnville, OR: With design work starting just last year, Northwest UAV (NWUAV) has now begun the manufacturing and parts procurement for their new NW-88 multi-fuel twin-cylinder engine (pictured below). Utilizing the same team that developed their internationally recognized NW-44 multi-fuel single-cylinder engine, NWUAV has begun to take the necessary steps to complete a prototype of the NW-88 engine to demonstrate exactly how it will function.

Built specifically for small unmanned aerial systems (UAS) that require extreme endurance, high reliability and advanced payloads, NWUAV’s NW-44 multi-fuel single-cylinder engine continues to see momentous success and continued adoption in small, professional-grade UAVs, filling a much-needed gap in the maturing UAS industry. Borrowing design elements from the NW-44 engine to offer the same endurance, efficiency and reliability for a larger weight class of UAVs, the Northwest UAV team expects the NW-88 multi-fuel twin-cylinder engine to fill another often-overlooked gap in the professional UAV market.


“Early on we recognized that Group II UAVs (unmanned aerial vehicles in the 40-75-pound weight class) were attempting to fly 12 hours or more in extreme conditions with the only engines they had available, which were hobby-grade engines designed for the weekend flier,” remarked Chris Harris, President and Owner of NWUAV.  “They needed a more reliable, efficient, cost effective engine solution, and that’s how the NW-44 engine was born. Due to their still relatively small size, Group III UAVs (in the 75-150-pound weight class) are experiencing the same endurance and reliability issues in their engine options that the Group II UAVs were facing. With the NW-44 and 1000 flight hours of experience, NWUAV is primed to deliver their next professional-grade engine for Group III UAVs rapidly and successfully.”

With the ground-up design of the NW-44 engine to work from, the manufacturing and parts procurement for the NW-88 twin-cylinder multi-fuel engine for Group III UAVs has already begun! The same team that completed the work on the NW-44 engine has begun manufacturing the cases and programming the quiet mufflers to fit the NW-88 engine prototype. Next, the team will tackle building the first NW-88 puck.

“Now that the NW-44 single-cylinder multi-fuel engine is firmly established as the new industry standard for 40-75-pound UAVs, we can efficiently adapt that design to support 75-150-pound UAVs,” Chris Harris continued. “And like its smaller, older brother, the NW-88 engine is set to be a complete engine system ready to install with minimal or no development costs for the end customer – a plug-n-play engine if you will – making it highly cost effective to adopt on existing platforms or incorporate into new designs.”

A completed prototype of the NW-88 multi-fuel twin-cylinder engine is set to be completed and on display for the first time at AUVSI XPONENTIAL 2018 in the Northwest UAV booth #2219, April 30-May3. Stop by our booth and see the NW-88 system for yourself!
