XPONENTIAL 2017: Northwest UAV Begins Development on New UAV Engine

NW-88 Twin-Cylinder Multi-Fuel Engine


Northwest UAV has recently initiated development of their new NW-88 Twin-Cylinder Multi-Fuel unmanned aerial vehicle (UAV) propulsion system based on the proven, ground up design of its own NW-44. With their NW-44 Engine successfully logging over 1,000 combat flight hours, Northwest UAV is, “ready to fill another niche in the UAV marketplace,” according to the company. The NW-88 engine will offer the same reliability, endurance and efficiency of the NW-44 engine to larger, heavier UAVs in the industry.

Built specifically for small unmanned aerial systems (SUAS) with approximate weights between 40-75lbs., Northwest UAV’s NW-44 Engine has seen momentous successes in a short amount of time, solidifying its reputation for reliability, efficiency and ease of maintenance. To build on this success, Northwest UAV has begun to develop an engine similar in design and quality to the NW-44 Engine with just one big difference – it supports UAVs twice the size. The NW-88 Multi-Fuel Engine will be just as quiet, heavy-duty and easily configured as the NW-44, and it will support UAVs in a weight range between 65-150lbs, according to the company.

Like it’s smaller brother, the NW-88 will be fuel injected and come with a high output generator and power management system, self-managed cooling system, dual ignition with twin spark and NWUAV’s game changing noise reducing, patented muffler. “Group II UAVs are not the only segment within the industry that are attempting to fly 12 hours or more in extreme conditions with hobby grade engines,” Chris Harris, President and Owner of Northwest UAV, said. “There are quite a few Group III sized UAVs well over 75lbs. that are using hobby grade engines that were never designed for the durability and reliability expected by end customers. Hobby grade engines are typically designed for the weekend flier at the local RC airstrip where they might get 100 hours flight time in five years, with no thought on how the engine will perform at 45c at 2,000m ASL let alone to achieve a 400-500 hour TBO. Compared to a UAV application where 45c and 2000 meters is the ‘Standard Day’ and 100 hours of flight time can be easily achieved in two weeks. These two scenarios require substantially different design and engineering considerations and NWUAV understands that. The NW-44 Multi-Fuel Engine has proven itself as a professional aviation grade engine designed for 40-75lbs. UAVs. Whereas the NW-88 will complement UAV’s in the 65-150lbs. range. And like the ITAR free NW-44, the NW-88 Multi-Fuel Engine will be a complete engine system ready to install with minimal or no development costs for the end customer – making it highly cost effective to incorporate.

The decision to fund the development of the NW-88 Engine is a demonstration of Northwest UAV’s continued commitment to providing the small UAV market with safe, reliable, aviation grade propulsion. It also helps facilitate the rapid growth of the unmanned systems industry by reducing barriers to entry for innovative technologies.
