UAV Engines — Powering the Future of Unmanned Aviation

NW-44 UAV Engine

43.6cc / 3.5hp – Single-cylinder – Multi-fuel – Approved for EAR99 Export

Northwest UAV | NW-44 HF UAV Engine

Engineered for endurance, reliability, and efficiency. Built for aircraft in the 18- to 34-kg (40- to 75-lb) weight class, the NW-44 UAV engine delivers consistent performance on both heavy fuels and gasoline, with over 28,000 operational hours logged in the field. Compact, lightweight, and low-maintenance, it provides UAV operators with a dependable, ready-to-deploy solution for long-range and demanding missions.

NW-88 UAV Engine

88cc / 7.3hp – Twin-cylinder – Multi-fuel – Approved for EAR99 Export

Northwest UAV | NW-88 HF UAV Engine

The NW-88 UAV engine is the most efficient and configurable UAV engine on the commercial market. A purpose-built propulsion system designed, developed, and built specifically for aircraft in the 34- to 68-kg (75- to 150-lb) weight class, with larger payload requirements; a combat-proven propulsion system for low altitude, and long-endurance flights, and reached flights up to 18,000 feet.

NW-230 UAV Engine

230cc / 15-18hp – Twin-cylinder – Multi-fuel – Approved for EAR99 Export

Northwest UAV | NW-230 HF UAV Engine

Endurance, Efficiency, and Power. Meet the NW-230 UAV engine EFI, a multi-fuel internal combustion engine designed explicitly for Group III UAS platforms, built for aircraft in the 90- to 160-kg (198- to 352-lb) weight class. The NW-230 is capable of operating on gasoline and heavy fuel (JP-5, JP-8, or Jet-A). Achieving flights to an altitude of ~36,000 feet DA, which is comparable to the altitude at which 737s fly daily.

Design Objectives

PERFORMANCE
Deliver consistent power output and fuel efficiency optimized for unmanned aircraft of varying size and mission requirements.
LIFECYCLE
Maximize time-between-overhaul (TBO) with robust, low-maintenance designs that reduce total cost of ownership.
ENDURANCE
Enable extended mission durations through optimized fuel burn, multi-fuel capability, and advanced electronic fuel management.
WEIGHT
Minimize engine mass while maintaining structural integrity and durability, supporting greater payload capacity and longer flight times.

NOTE: Actual performance will vary depending on PMU configuration, application, propeller, fuel type, oil, environmental conditions, type of operation, direction of rotation, generator losses, and cowling configuration. Engine application is dependent on airframe factors including: Aerodynamics, propeller, and operational concept. Fuel is subject to regional and seasonal variations. The user is responsible for testing, validating, and defining operational limits with their local fuel source. Weight does not include Generator, Generator Controller/Rectifier, or Propeller. Includes: ECU, Muffler, Engine Mount, ACHT, and Engine Harness. Horsepower depending on propeller/RPM. Please contact NWUAV for guidance.
