Thielert Centurion 1.7
The Thielert Centurion 1.7 is an aircraft engine from the German manufacturer Thielert Aircraft Engines GmbH. He is a liquid-cooled 4-cylinder in-line four-valve Common Rail - Diesel engine power class of 100 kW (135 hp). The engine is no longer produced in this version. It is replaced by the newer Centurion 2.0 with similar but not the same technical data. After the takeover of Thielert by AVIC , the engines are sold as Technify TAE 125 .
history
The engine, equipped with a reduction gear (1.69: 1) and turbochargers with charge air cooling , is the first new development of a kerosene piston aircraft engine for civil aviation since the Second World War.
The engine has a fully electronic, redundant engine control ( FADEC ). The Centurion 1.7 was first used in 2002 in the Diamond DA40-TDI. The engine is approved according to JAR-E and FAR 33 . Use in China has also been approved since February 2005, and the engine has been certified for the Piper PA-28 and Cessna 172 in the USA since 2006 .
An overhaul is not planned. It was planned that the engine would be replaced after the operating time of 2400 hours. In fact, the FAA set the TBR (Time Between Replace) for type certification in 2003 at just 1000 hours and in Europe there was only a “ pro rata ” guarantee for 2400 hours. The engine is a Mercedes-Benz OM 668 diesel car engine adapted for aviation , which was used in the A-Class and B-Class (T245) , among others .
The successor engine Centurion 2.0 (an adapted Mercedes-Benz OM 640 ) is now being installed in series in the following aircraft:
- Diamond DA40 -TDI
- Diamond DA42 Twin Star
- Röder-Cessna Skyhawk A1
- Robin DR 400-135 cdi Dauphin
- MQ-1C Gray Eagle , armed drone
- TAI Anka , a reconnaissance drone ( MALE )
Conversion kits exist for the Piper PA-28 model.
At the end of 2006, the Centurion 1.7 was replaced by the successor model Centurion 2.0. Over 1500 Centurion 1.7s were built in the three years of series production.
