Airframe Will Showcase New Lycoming IE2 Engine
Lancair International says customer response to its new
Evolution turboprop has been phenomenal, but some potential
builders expressed their desire to build the high-performance
homebuilt without a turbine engine. The Bend, OR-based kit maker
has responded... teaming up with Lycoming to offer a new piston
power plant for the Evolution.
And that engine won't be your garden variety boxer 4-cylinder.
Unveiled Monday at AirVenture 2008, the new
Lycoming TEO-540-A IE2 piston engine delivers 350hp @ 2500 rpm and
the single lever control reduces pilot workload as the Full
Authority Digital Electronic Control monitors all phases of flight
from startup to landing, delivering optimum engine performance at
each stage of flight.
"Lancair International chose the Twin Turbocharged 540 cubic
inch IE2 engine because of the advances Lycoming has made in its
overall engine technology," the company says. "The engine control
system features multi-channel safety redundancy and incorporates
advanced algorithms for controlling the throttle, fuel mixture,
turbo chargers and the propeller."
Lancair says the new engine will propel the Lycoming-powered
Evolution to a maximum cruise speed of 270KTAS at FL280 in
pressurized comfort. The engine is expected to use just 22 gallons
of 100LL per hour, providing a range of 1300 nm (with 45 minute
reserve). Full fuel payload is 1080 pounds.
Like the Pratt & Whitney PT6A-135A turbine-powered Evolution
(shown above), the Lycoming-powered bird is also designed to
provide a new level of safety and stability with its slow pattern
and landing speeds. In addition, the BRS parachute system, energy
absorbing seats, and the AmSafe Aviation airbag seat belts are
available.
The estimated price for the completed piston Evolution, before
options, is under $600,000. That's not cheap... but it might just
be the highest-performing bang for your aero-buck out there.
