Endurance And Reliability Test Runs Showing 'Impressive' Results
Northwest UAV’s NW-88 heavy fuel twin-cylinder UAV engine continues to complete successful test runs … and the numbers are impressive. As interest in the engine grows, Northwest UAV looks forward to seeing the NW-88 in the skies later this year.

In just over a year the NW-88 heavy fuel engine has transitioned from concept to prototype to a well-tested engine. With a market eager for a reliable, efficient engine for Group III UAVs, the NW-88 heavy fuel UAV engine is poised for success, like NWUAV’s NW-44 UAV Engine before it.
The NW-88 heavy fuel twin-cylinder UAV engine is set to fill mission gaps in the maturing UAS industry, much like the NW-44 UAV Engine has done before it. The aviation grade NW-88 engine is designed to offer endurance and reliability gains to Group III UAVs in the 75-150 pound weight class, which are increasingly being used for commercial and military purposes.
“We noticed as the popularity of the NW-44 engine grew, that Group III UAVs in the 75-150-pound weight class were experiencing the same endurance and reliability issues that the NW-44 engine addressed in Group II UAVs,” Chris Harris, President and Owner of Northwest UAV said. “OEMs and end users (the OEM’s customers) are hungry for an aviation grade option, which is to say that they are looking for a higher level of maturity, maintainability, reliability, and consistency in their propulsion system. We’ve taken what we’ve learned from developing aviation grade qualities in the NW-44 engine and applied those technologies to the NW-88. In fact, many of the components on the NW-88 are shared with the NW-44. Utilizing proven components greatly reduced the NW-88 development timeline as well as cost and has resulted in superior test results. In addition, these shared components are cost effective for customers deploying both the NW-44 and the NW-88, which were
designed for easy maintenance and overhaul.”
