EAA AirVenture Oshkosh RSS FeedNew power options for experimental, LSA markets from Lycoming
By James Wynbrandt
Engine choices for light sport and experimental aircraft just got broader after Lycoming Engines of Williamsport, Pennsylvania, announced new power options for both segments Monday at EAA AirVenture Oshkosh.

In the experimental category, Lycoming’s new TEO-540-EXP Integrated Electronic Engine (iE2) will now be available on the Lancair Evolution.

The iE2, a twin-turbocharged and intercooled 350-plus hp engine, features a single lever that manages all the elements of engine power:  manifold pressure, rpm/prop speed, fuel flow, and ignition timing—all automatically to deliver optimum power performance.

“You set PLA and go fly a complex aircraft,” said Michael Kraft, senior vice president and general manager of Lycoming Engines. “We are extremely proud to be able to bring this technology to the market.”

Lancair has been operating its pressurized Evolution kit aircraft with an iE2 for the past year, serving as a development platform for the engine.
Said Thomas Bowen, Lancair’s chief operating officer, “We are excited that now Lancair can begin showing the world the product that has had us smiling for the past six months as the program has come to its conclusion.”

Bowen flew the iE2 powered Evolution to AirVenture and reported achieving a true airspeed of 253 knots at Flight Level 270.

Lycoming plans to offer the experimental engine only through OEMs. Lancair is pricing the iE2 in the Evolution at $115,000.

According to Lycoming, the iE2 will be the first in a family of engines that will include certificated models. The company reports it has been speaking to OEMs of production aircraft about using certified versions of the engine, but declined to name the companies.

Lycoming also announced it is taking orders for non-certified versions of its 115-hp 233 series LSA engine first introduced here at AirVenture 2008.

“The engine is light and capable of running on unleaded automotive fuels as well as aviation gasoline—with the built-in 235 family reliability customers expect from Lycoming,” Kraft said.

The engine features dual CDI spark ignition, an optimized oil sump, streamlined accessory housing, hydraulically adjusted valve tappets, lightweight starter, and a lightweight alternator with integral voltage regulator. The 233 offers continuous power ratings up to 115 hp at 2800 rpm.
Certification is pending.

The standard 233 engine is carbureted, but Lycoming plans to offer a fuel-injected version as well. The engine is available through Lycoming’s Thunderbolt line of custom engines.

FUTURE AIRVENTURE DATES: 2014: July 28-Aug. 3; 2015: July 20-26; 2016: July 25-31; 2017: July 24-30
