Formed in 2006, ULPOWER Aero Engines is a small Belgian company which started as a joint venture by a number of individuals and companies. Their intention is to develop and manufacture a light weight aero engine where power and reliability is priority number one.
This has resulted in the UL260 and UL350 family of engines. Designed as a four cylinder, air cooled, direct drive, multipoint injected and FADEC equipped low RPM engine. To this day several aircraft manufacturers have included this engine in their designs. One could say that the designers have succeeded in their goals.
In 2014 we saw the introduction of a new range of six cylinder models from this company. They are based on the same construction principles and as such they have continued their novel design philosophy into higher powered engines.
The company has continued development into the fuel injected UL350iS (118/150 bhp @ 3300 RPM) and even an 107 bhp aerobatic version (UL260iSA). We have an overview of all their engines in ULpower engine overview.
At AERO 2014 ULpower introduced new six cylinder engines ranging in power output from 140 - 160; the 180 - 200 hp range was introduced in 2015. The engines are called UL390 and UL520 and the installed weight is between 101 and 108 kg. Both engines are FADEC controlled and enjoy these benefits too. For more information on these interesting engines visit ULpower. North American visitors may visit their local ULpower dealer.
These engines are available in low and high compression models (between 8:1 and 9.1:1). This enables them to use everything between Mogas RON 95 (maximum of 15 % ethanol) and AVgas as a fuel. Be careful that the high compression engines are not able to use Mogas RON 95 due to the lower octane content of that fuel.
These images were taken at AERO in Friedrichshafen (Germany) and show an installed UL260i and an UL350 engine, click them for a slide show.
