As America’s leader in UAV propulsion system design and manufacturing since its founding in 2005, Northwest UAV (NWUAV) is leading the way yet again, as one of America’s first one-stop-shops for the UAV industry. With a reputation for reliable, cost effective and innovative UAV engine and support system solutions, NWUAV has evolved into a company with the ability to design, manufacture, build-to-print, repair, ground test and flight test UAVs in their FAA designated airspace. When reliability is key, count on the team at NWUAV. AS9100/ISO9001 (AS9104-1) Certified, DCAA compliant operation.
Northwest UAV has taken their newest engine – the NW-88 multi-fuel twin-cylinder UAV engine – from concept to running prototype with a successful test run in their on-site engine test cell. This marks the conclusion of the design phase of development and begins the test and qualification phase. Based on these successful initial test runs, the NW-88 UAV Engine is set to be qualified and in the skies in 2019.
McMinnville, OR: After beginning the program early this year and producing a concept prototype just this May, Northwest UAV is proud to announce the completion of the first test runs on its newest engine, the NW-88 multi-fuel twin-cylinder UAV engine.
Following the successes of the NW-44 engine, the NW-88 multi-fuel twin-cylinder UAV engine is set to fill other mission gaps in the maturing UAS industry. The NW-88 engine is designed to offer endurance and reliability to Group III UAVs (in the 75-150-pound weight class), which are increasingly being used for commercial and military purposes. While organizations are trying to field hobby-grade engines, NWUAV President and Owner Chris Harris has been developing an Aviation Grade solution.
“With the success of our NW-44 single-cylinder UAV engine offering a more reliable, efficient, cost effective solution for Group II UAVs, it’s just a natural progression for us to offer that same reliability and efficiency for UAVs one weight class heavier that are dealing with the same issues,” Chris Harris said. “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. We have taken what we’ve learned with the success of the NW-44 engine and applied it to the NW-88 engine. In fact, many of the components on the NW-88 are shared with the NW-44, which reduced the development timeline as well as development costs. Should a customer that operates the NW-44 decide to deploy the NW-88 for an alternate airframe or need more power for a current airframe, many of the spares inventoried for the NW-44 are compatible with the NW-88. This can be very cost effective for our customers.”
Northwest UAV has set the bar for UAS industry standards in propulsion over the last thirteen years, performing well over 10,000 hours of development testing on multiple platforms. All of NWUAV’s systems are designed to operate on heavy fuel or gasoline and fly for more than 18 hours in a broad variety of climates with the highest power to weight ratio. Their patented cooling systems boast the most comprehensive temperature envelope in the industry. NWUAV has taken extra steps to assure their propulsion solutions are straightforward for ease of maintenance whether on-site at their facility or mission deployed, a critical element for all operators. The NW-88 will continue its testing and fine-tuning in NWUAV’s own climate controlled on-site engine testing facilities which include temperature-controlled test stands and altitude chambers.
“Using our own testing facilities allows us to control every aspect of testing and to collect all of the data required to be effective and efficient in the development process.” said Jeff Ratcliffe, Chief Technical Officer of NWUAV. “It allows us to confidently say you can fly even the most difficult missions and expensive payloads at the highest altitudes and in the broadest weather conditions because we’ve designed and tested the engine to do just that. The investment we put into testing and perfecting our engines is a big part of the reason the industry is so excited about the NW-88 engine! Well, that and the proven performance and reliability of the NW-44 engine.”The NW-88 engine is set to complete development testing this year and is expected to be in the skies by the second quarter of 2019.

McMinnville, OR: Northwest UAV (NWUAV), the largest UAV propulsion system manufacturer in the U.S., has successfully completed the first phase towards Federal Aviation Administration (FAA) 14 CFR Part 21 Type Certification in support of the NW44 type certification program.
Members of the FAA team, which comprised FAA Flight Standards (AC-AW), AIR UAS Programs and Procedures Division, AIR Policy & Innovation Division and the Engine Directorate, came together on October 16th and 17th at NWUAV headquarters in McMinnville, Oregon for the first gated certification process in collaboration with the FAA.
NWUAV clearly presented its advanced captures of 14 CFR 33 and 35 data, the process for Risk Assessment utilizing Safety Management principals founded in current Part 5 regulatory basis and the ability to transition to ISO based production capability pursuant to eventual Production Certification and Part 145 services. This critical meeting demonstrated the intent of NWUAV to establish high consequence, critical success attributes in every UAS engine design and subsequently bring the UAS industry to the highest standards in airworthiness and aviation safety. The availability of an FAA 14 CFR 21.17(a) type certificated powerplant will provide significant opportunity for airframe manufacturers to successfully and efficiently navigate the civil certification requirements for their aircraft with an off the shelf availability of a NWUAV Type Certificated engine/propeller set.
The NW-44 Heavy-Fuel Engine – Northwest UAV’s purpose-built propulsion system for small unmanned aircraft systems – has now successfully logged over 10,000 combat flight hours and 1000 flights in combat conditions. As the NW-44 Heavy-Fuel Engine continues to set new standards in the field, Northwest UAV is charging forward, building the future of UAS at home.
February 27, 2019 | McMinnville, OR: Just over a year ago Northwest UAV announced that the NW-44 Multi-Fuel Engine had reached the noteworthy milestone of logging over 1000 combat flight hours. Today, that same engine line has flown over 10,000 flight hours and has logged over 1000 flights. As the NW-44 engine soars, Northwest UAV is hard at work at home, adding manufacturing and office space to their campus as they look to the future of unmanned aircraft systems.
Purpose-built for Small Unmanned Aircraft Systems (SUAS) that require extreme endurance and high reliability, the NW-44 Engine is a lightweight, multi-fuel UAV engine that has been designed and built to be easily adaptable, meeting the most challenging mission requirements. The NW-44 is a complete turn-key engine system designed to be the Commercial Off-The-Shelf (COTS) solution that virtually eliminates development costs for the OEM, saving customers millions of dollars and several years stuck in the engineering development cycle. Filling a niche in the UAV marketplace, the NW-44 supports aircraft with approximate weights of 40-80 lbs. It is a heavy-duty, reliable, extremely quiet, combat proven engine for the Tier II UAV sector, yet it is still cost competitive with hobby grade systems on a cost-per-flight-hour basis.
“The engine core is critical to reliability, but it’s just a portion of the overall cost of the entire engine system. This is true whether it’s a hobby engine or a purpose-built engine,” says Chris Harris – President and Owner of NWUAV. “Since we can overhaul the NW-44 multiple times, it spreads out the cost of our engine system over a thousand or more flight hours. It is understandable why companies seeking to minimize development costs have decided to use hobby grade engines in the past. However, once systems reach a decent level of maturity, companies are often are forced to redesign their systems due to inconsistent quality, or parts that go obsolete with little notice, which is commonplace in the hobby engine industry. Now that the NW-44 engine is an option, there is no reason to take those risks!”
As the NW-44 Heavy-Fuel Engine hits this major milestone of 10,000 combat flight hours and 1000 flights out at the sites, back home, NWUAV continues to evolve, growing its campus to meet not just current, but future needs of the UAS industry. Adding an additional 30,000 sq/ft of facility space to their campus, Northwest UAV is becoming a one-stop-shop for the UAV industry. The design and development effort for the NW-44 defined the way NWUAV approaches engineering projects, as the NW-44 was an internally funded effort, efficiency and speed were mandatory while maintaining high quality. It also helped NWUAV discover gaps in the UAV industry that desperately need to be filled. That’s why NWUAV’s 60,000 sq/ft facility offers dedicated customer services, such as an on-sight machine shop, 3D printing/manufacturing operation, aero/mechanical/electrical engineering services, drafters, technical writers, wire harness production shop, and a fully capable AS9100 production facility all at one location that is DCMA audited. NWUAV has also dedicated up to 15,000 sq/ft of space in the new construction to be divided and isolated for customer defined efforts to support engine, autopilot or payload integration, as well as new UAS development and volume production.
“We know how difficult it is to bring all these services together, which is why we have worked so hard to create this incubator for the UAS industry. Our customers will be able to bring their solutions to market much quicker while spending less on development” said Heather Sorenson, Director of NWUAV. “Between NWUAV and our well-vetted supply base, we can support ‘build-to-print’ projects or a customer’s clean sheet design, from conception all the way to volume production – all from our campus in McMinnville Oregon.”

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.
McMinnville, OR | April 23, 2019: 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.”
As NWUAV continues to test the NW-88 heavy fuel engine in their test facilities, market interest in the engine continues to grow. “We are really pleased with the performance of the NW-88 and are seeing impressive BSFC and HP numbers as it relates to the displacement and overall size and weight of the engine”, said Chris Harris. “When OEM’s select an engine solution they consider many things, but one critical factor that typically gets ignored or overlooked while reviewing performance data is the size of the engine and the associated parasitic drag that will be induced into the airframe, which can have a dramatic effect on endurance. When developing engine systems, we focus heavily on packaging and reducing the overall footprint by incorporating technology such as our patented conformal muffler designed for best BSFC at cruise. We have been asked many times about the potential of efficiency gains with direct injection. We have purposefully stayed away from that approach due to the additional parasitic drag that is induced with the increased cylinder height and the limited time for an injection event on small displacement 2 stroke engines. On a 4-stroke engine there is roughly 270 degrees of crank rotation to inject the required amount of fuel. On a smaller 2-stroke engine there is about 30 degrees of crank rotation after the transfer and exhaust ports are covered by the approaching piston. This leaves about 2 ms to inject fuel, or ~½” of piston movement, before the spark event … To expect a consistent homogeneous fuel mixture prior to the spark event seems unrealistic.”
The NW-88 boxer twin has a unique injection strategy that utilizes twin throttle bodies, injectors and dual rotary valve intakes. This engine core design addresses an industry-wide issue with boxer twins, where both cylinders share the lower end volume leading to variable fuel mixtures at different throttle settings and altitudes. NWUAV’s strategy permits a matched homogeneous fuel mixture between cylinders, which ensures the heavy fuel is well-vaporized prior to entering the cylinder. This leads to impressive BSFC numbers throughout the RPM range.
“The NW-88 engine is a commercial off-the-shelf (COTS) aviation grade engine just like the NW-44,” Harris explained, “A COTS engine solution saves OEMs a substantial amount of time and money. Rather than trying to develop and mature their own engine system, a process that takes years, Northwest UAV does the work for the OEM. We understand the full progression from the ground up, including the cost and infrastructure required to mature initial engine development systems into qualified tested production products.”
