Nelson H-44 Type Two-stroke aircraft engine National origin United States Manufacturer Nelson Engine Company Designed by Ted Nelson Major applications Bowlus/Nelson Dragonfly Produced circa 1947 The Nelson H-44 is an American single ignition, four cylinder, horizontally-opposed, direct drive, two stroke aircraft engine that was developed by the Nelson Engine Company for use in motorgliders.[1]

Design and development
The H-44 was designed in the period following the Second World War and a specially designed motor glider was created by Hawley Bowlus to utilize the engine, the Bowlus/Nelson Dragonfly.[1]
The engine was not certified. Under the CAR 5 regulations then in place in the USA for gliders, a certified auxiliary power glider could be flown with a non-certified engine and propeller. The engine is instead described on the Dragonfly type certificate.[1]
The four cylinder engine runs on a 12:1 mixture of 80 octane gasoline and SAE 30 oil. It is equipped with a single Carter WA1 carburetor and a recoil starter.[1]
Operational history
Employed in the Dragonfly the H-44 proved underpowered, which lead to the design of the H-49 version. The engine family was not a success and few were produced.[2][3]
