News of February 25, 2007Vulcan Aircraft Engines, LLC was formed to bring world class turbo diesel technology to general aviation.Vulcan Aircraft makes an initial entry into the Light Sport Plane market, with the Raptor 105. It is a diesel engine intended to compete directly with the Rotax 912 ULS and Rotax 914. Using less fuel than a 912ULS and with more power than a 914 in a smaller physical package, the Raptor 105 may be the ideal engine for any Light Sport Aircraft. Vulcan has gone to great lengths to produce an engine that is comparable in weight with equal HP gasoline engines, much less existing diesels. Gasoline powered aviation engines in this range generally weigh 1.5 to 2 lbs per HP. For example, the Rotax 914 is rated for 100 HP continuous operation and weighs 166 lbs for a weight to power ratio of 1.66 to 1. The Raptor 105 produces 105 hp continuously and weighs 179 lbs for a weight to power ratio of 1.7 to 1. Also it currently meets all applicable emissions regulations and is ready to meet proposed future standards. Most aircraft in the 80-120HP range have gasoline engines. The advantages of diesel engines are already well-known. The problem has been in two very important areas; weight, and cost. The Raptor brand engines are a direct replacement for gasoline engines and are intended at a cost that is comparable with existing gasoline engines. All Vulcan engines are made in the United States.
