News of November 22, 2005The Beech Duke Thielert conversion shows what a breakthrough diesel can makeGermany: The Beech Duke with Thielert V8 350HP has flown for the first time on November 18. This is the first diesel conversion that demonstrates a reduced weight compared with original gasoline engines: Exactly 50 Lbs. The Duke diesel is faster by 10 Knots at FL 220 despite a slightly lower power at sea level. Here is comparative performance figures claimed by Martin Hagensieker, see http://www.dukeb60.de/ with photographs: ______________Diesel V8__________________Lycoming Power_________350 hp_____________________380 hp At rpm________2.300______________________2.900 Cruisepower______70 %_______________________67 % At rpm________2.000______________________2.500 Fuelflow/h______2 x 45 ltr./11 gal._____________2 x 80 ltr./20 gal.

And, at the (low) market price of a Beech Duke today, plus some $ 400,000 conversion cost, and a fuel flow of 22 gallons/hour of Jetfuel, it will be the most affordable business aircraft for such a mission. posted at 1:56 AM |
