April 11 2008 — IndUS Aviation introduced the first diesel-powered light-sport aircraft (LSA), the Thorpedo DP, at the Sun 'n Fun Fly-In on Friday. Calling it a step forward in environmentally friendly aviation, IndUS Sales and Marketing Manager Scott Severen said the proof-of-concept aircraft flew in from Dallas, Texas, where IndUS is based, to Florida earlier this week, but the engine, the WAM 120, has been flying on a Thorp T211 in England for the past four years with some 400 hours logged.
The 120-hp engine is a three-cylinder, two-stroke, liquid-cooled, turbocharged engine installed in an inverted configuration. With its cooling pack, it weighs 220 pounds empty; installed wet, including propeller, it weighs 269 pounds. Fuel consumption (Jet A) is 3.5 to 4 gph. It is the first ASTM-compliant diesel engine to enter the marketplace.
"Avgas isn't available around the world like it is here in the United States, so to make general aviation accessible around the world we need an aircraft that uses a fuel that's more readily available," said IndUS Aviation President Ram Pattisapu. "A diesel-powered aircraft will be incredibly valuable to many people. First we'll prove its viability here in the United States as part of the 'green' revolution and then we'll take it to the rest of the world."
IndUS expects to earn special light-sport aircraft approval prior to EAA AirVenture Oshkosh, which takes place July 28-August 3. For more information, visit www.IndUSAv.com.
