The FAA has granted FAA-PMA approval to the new Hartzell Engine Technologies ALV-9610 100-amp alternator for Continental -470, -520 and -550 piston engines, which replaces the original Crittendon and ALV-9510 units. The new alternator weighs 12.75 pounds, saving up to 9.25 pounds per alternator, and features a compact design with integral noise filtering. Cost of the ALV-9610 is $1,100, with a $425 core charge and two-year warranty.

Eurocopter might exhibit a hybrid helicopter, using both piston engines and electric motors like a hybrid car, by Heli-Expo 2020. Parent company EADS last year unveiled a helicopter concept that could burn 50 percent less fuel than its traditional equivalent. EADS Innovation Works is devising a way to combine diesel engines, generators, batteries and electric motors.

Chromalloy is offering a new thermal barrier coating it claims enhances the performance of gas turbine engines. "The RT-35 Low K coating provides lower thermal conductivity, which allows higher engine temperatures. Engines produce greater thrust when operating at higher temperatures and they can operate on the same amount of fuel as powerplants that operate at lower temperatures," said Dr.

Turbofan manufacturers are developing cleaner, quieter and more environmentally friendly engines that will meet current and future regulatory requirements. That fact should come as no surprise, since they have been doing this all along as the natural byproduct of efforts to build more fuel-efficient and quieter turbofans for a market that demands nothing less.

Anthony Mosallam and Jonathon Deming, students at the Flabob Airport Preparatory Academy in Riverside, Calif., designed and built a turbine engine for their high school’s annual science fair. The engine was made from auto parts and a leaf blower, which was used to provide air to start the engine. A Buick Regal turbocharger was used as the compressor, and propane powers the engine.

The GE Honda joint venture last Thursday fired up the first conforming version of its new 2,095-lb-thrust HF120 engine currently slated for certification  in 2011. Initial engine tests are typically completed in a sea-level test cell, with high-altitude performance testing conducted onboard an aircraft.

General Electric’s Unison Industries subsidiary has sold its Aircraft Parts Corporation (APC) business unit to TransDigm Group for approximately $68 million in cash. APC, a 50-year-old company based in Holtsville, N.Y., manufactures turbine-engine starter generators, generator control units and related components for Cessna Citations, Bombardier Learjets and Bell and Agusta helicopters.
