Company Claims Cooler Engine Operation, Increased
Vitatoe Aviation of Chillicothe, OH has developed the Centurion
TN550, based on Cessna P210 and T210 aircraft. The difference is
under the cowling, where Vitatoe installed a Teledyne Continental
IO550P engine, but retained the original turbocharger, allowing for
increased performance at altitude over the original TSIO520P engine
and the naturally aspirated IO550. The company expects STC approval
to be completed in the fourth quarter of 2009.
The IO550P engine has a higher compression ratio for improved
fuel efficiency and power. The new configuration also features dual
intercoolers to the revised Cessna turbocharger induction system
for improved charge air cooling. These additions have provided
cooler engine operations at all altitudes.
The prototype aircraft has also been fitted with a Hartzell
7693DF+2 prop for increased performance and quieter operation.
Early flight tests have produced excellent results, with true
airspeeds of 208 knots at 17,500' MSL, operating with lean of peak
fuel settings of 17.6 gallons per hour. Cessna P210N aircraft are
certified to 23,000'.
Vitatoe reports that the cool engine operation is possible by
utilizing the TCM flow thru cylinders. Induction air is provided by
the turbocharger, cooled by twin intercoolers, and evenly
distributed by the tuned induction system. Serviceability was also
enhanced and engine clutter reduced by the new location of the
throttle body and induction tubes on top of the engine, compared to
the original configuration of rear or bottom mounted locations.
The Cessna P210 airframe is a proven design offering many
options and accessories. In addition to the comfort of
pressurization, the P210 has a proven record of reliable flight
characteristics. Now owners of existing P & T 210's can have
the latest engine technology, propeller technology and performance
for much less than the price of a new aircraft.
In addition to engine alterations, Vitatoe Aviation can arrange
exterior, interior and avionics packages to bring P & T 210s to
better than new performance and appearance.
