Gang,
I wrote Thielert about the feasibility of installing their engine in an
experimental aircraft - specifically a Legacy. The reply:
Dear Mr. Keyworth,
Thank you for your interest in the CENTURION
aircraft engines product range. Currently we do offer the CENTURION 2.0
(135 PS) engine and the CENTURION 4.0 (350 PS).
Whereas the CENTURION 2.0 (135 PS) can be fuelled
with either Diesel or Jet A1, the stronger CENTURION 4.0 is a pure Jet fuel
engine. Today the CENTURION 2.0 (135 PS) holds an EASA and an FAA
type-certificate. Our new CENTURION 4.0 is EASA type certificated and we
are presently working on the FAA certificate.
The CENTURION 2.0 (135 PS) engine offers - in
comparison to the original engines of the Cessna 172 and Piper 28 series - many
advantages concerning the safety, comfort, performance and fuel
efficiency. Especially the enormous profitability of our engine is due to
the significant lower fuel consumption with the cheaper Diesel or Jet A1
fuel.
We do offer Retrofit-Kits for a variety of models
from the Cessna 172 and Piper PA 28 series. Each Kit includes: New engine
mount, engine, reduction gear, turbocharger, starter, alternator, cooling
system, prop governor, vacuum pump, single lever control selector, FADEC, engine
instruments, wiring harness and a new MT-variable pitch propeller.
The same benefits basically will be offered by the
CENTURION 4.0 Jet Fuel engine:
The engine will be single lever controlled through
our FADEC (Full Authority Digital Engine Control).
Max power of 350 PS(DIN 15°C) will be available for
5 minutes; propeller 2.300 RPM.
Full HP will be available up to approximately
12.000 ft.
Max continuous power will be appr. 330 PS(DIN
15°C); propeller 2.300 RPM.
At 18.000 ft we estimate approx. continuous 290
PS(DIN 15°C).
At FL 240 we estimate approx. continuous 250 PS(DIN
15°C).
Certified service ceiling is FL 250.
For the cabin pressurization a separate compressor,
driven by our accessory gear, will be available.
Full power (350 PS DIN 15°C) fuel consumption at
sea level = roughly 20.1 gallons per hour Best Economy (60 % rated power - 210
PS DIN 15°C) = estimated 11.0 gallons per hour
We currently estimate the weight of the CENTURION
4.0 complete & dry including the gearbox, starter, alternator, harness and
FADEC depending on the installation, at 620 lbs.
As mentioned, until today Thielert Aircraft Engines
has developed Retrofit-Kits for the Cessna 172 and PA 28 series with our smaller
CENTURION 2.0 (135 PS) engine.
Our engines show a different complexity and have a
highly sophisticated electrical system, which requires an installation according
to regulations and procedures as you find in certified aircraft. Thus, we cannot offer the CENTURION engines for
experimental/Kit installations. [Emphasis mine]
If you do have any further questions, please do not
hesitate to contact me.
Sincerely
Wolfgang
Biereth
