July 29, 2009 - Oshkosh, Wisconsin - With
concerns about the cost of aviation fuel and emissions both running high,
Teledyne Continental Motors (TCM) and Lycoming, the two major U.S. piston
engine manufacturers, are showcasing some of their solutions at Oshkosh.
Mobile, Alabama-based TCM announced receiving FAA Certification for the
first Full Authority Digital Electronic Controlled (FADEC)- turbocharged
engine, the 350-hp TSIOF-550. TCM president Rhett Ross says the engine was
developed “in response to requests from airframe manufacturers wanting a
high horsepower engine offering, mated with advanced electronic engine
TCM’s PowerLink FADEC allows single- lever
control of the engine. Pilots select either best power or best economy,
and the engine automatically adjusts mixture and propeller pitch for all
phases of flight accordingly. An experimental version of the TSIOF550 has
been flying on the front of a Lancair IVP for over 550 hours, and it has
cruised at 255 knots on 17.5 gph fuel burn.
TCM has also been active in developing engines
compatible with alternative fuels. President Rhett Ross and company pilot
and engineer Keith Chatten flew its factory turbocharged Cirrus SR22 with
a standard TCM production engine to Oshkosh using UL94 unleaded aviation
fuel. With ASTM working for certification of UL94,
TCM has shifted from testing the fuel to
readying its engines for its introduction.
“Today’s flight demonstrated that our
standard factory turbo is ready for future fuels and has the fuel economy
necessary to benefit our customers,” Ross said. The company has
successfully flown both turbocharged and normally aspirated engines on
TCM also introduced what it’s calling the
TR22, for Turbo Realized 22, engine. Initially developed for the kit and
experimental aircraft markets, it is now the subject of an aggressive
Supplemental Type Certificate (STC) program, aimed at retrofits of Cirrus
SR22 aircraft. According to TCM, the TR22 will deliver a 3,000 fpm climb
rate at 130 knots at sea level, and provide max cruise performance of 196
knots at 9,000 feet and 204 knots at 18,000 feet. The company expects to
receive STC certification by the end of this year.
The new engines, the TSIOF550- powered Lancair,
and the company’s UL94-burning SR22 are on display at the TCM booth,
Lycoming, of Williamsport, Pennsylvania, is also heavily involved in
alternative fuels research. That includes current testing of 100SF, a
renewable fuel under development as a possible replacement for 100LL,
usable without modifying existing engines. Lycoming is providing the
engines for testing the Swift Fuel, which is undergoing evaluation.
At AirVenture 2008, Lycoming announced its iE2
engine series, designed as an alternative fuel-friendly powerplant.
Lycoming chose Lancair International of Redmond, Oregon, as the launch
customer for the non-certified engine, and the maiden flight of an iE2
engine occurred July 2, when a TEO 540-EXP iE2 powered a Lancair
Evolution. That aircraft flew to AirVenture this year and is on display at
the Lycoming booth. The 350-hp twinturbocharged and intercooled engine is
the first iE2 model planned.
The first OEM installations are being
calibrated and the certification program is underway.
Lycoming is also debuting its IO-233- LSA
light-sport aviation engine. The 116-hp LSA engine will be FAA-certified.
Lycoming will commence onwing ground, taxi,
and flight testing of the 116-hp immediately following AirVenture.
Additionally, Lycoming is displaying its new
IO-390-A3A6, a 210-hp upgrade of its popular 200-hp IO 360. The company is
seeking both certification and a Supplemental Type Certificate (STC) to
install the engine in three legacy models of the Mooney Airplane Company’s
M20 E, F, and J models.
