Improved hover performance in high and hot conditions for the Bell Huey and its derivatives is the promise of the FastFin tail-rotor enhancement and stability system from Boundary Layer Research (Booth No. 2970) of Everett, Wash. The company recently delivered its 100th UH-1 FastFin and announced that Wildcat Helicopters, Kelowna, British Columbia, will become the first fleet customer to install the system on the Bell 212.

News and issues regarding all manner of civil and military rotorcraft powerplants.
Honeywell Aerospace (Booth No. 1310) announced the selection of its LTS101-700D2 turboshaft to replace the existing engine in the Chinese Z-11 helicopter. New production engines will begin leaving the Honeywell Engines Phoenix plant for China in the first quarter of next year, said Doug Kult, director of helicopter and surface systems sales.
Aerospace Filtration Systems (AFS) of St. Louis announced recently it received a supplemental type certificate (STC) from Transport Canada for its engine inlet barrier filter systems for the Eurocopter EC 130 B4 and AS 350 B3 helicopters with dual hydraulic systems. European (EASA) approval is in process.
Honeywell is at Heli-Expo (Booth No. 1310) debuting its latest iteration of Zing for civil helicopters, an on-condition maintenance diagnostic system. A military version of Zing has been keeping U.S. Army Apache attack helicopters flying in some of the world’s worst conditions.
Honeywell Engines comes to Heli-Expo with five turboshaft models ranging in age from venerable to brand-new and in power from 1,000 shp to 5,000.
Despite announcing last week that it is laying off 10 percent of its 10,000-strong global workforce because of global recession, aircraft engine manufacturer Pratt & Whitney Canada remains committed to developing new products, according to company president John Saabas. It is working hard to meet, but not exceed, demand, while continuing to support 44,000 in-service engines.
Pratt & Whitney Canada’s new 1,000-shp-class PW210S turboshaft engine, which has been developed to power the Sikorsky S-76D and is on offer to other manufacturers for new-build and retrofit applications, is “on track and meeting performance.” The Montreal manufacturer told HAI Convention News that key performance tests had been “successfully completed” as it continues to optimize the engine.
French-based turboshaft manufacturer Turbomeca has completed a European Commission-funded research program that opens the door to a massive collection of usage and maintenance data on helicopter engines. The idea is to have engines sending an exhaustive set of data, after each flight, to a centralized server.
As we round the corner past the U.S. Labor Day weekend, thoughts of cold-weather operation begin to make their unwelcome presence felt, especially among operators of unhangared aircraft. Cranking up a mechanically complex aircraft on a subzero morning can put lifetime-limiting stresses on drivetrains. This is especially true when it comes to rotorcraft, with their high number of crucial moving parts.
Rolls-Royce unveiled a new turboprop engine for general aviation applications on Tuesday at EAA AirVenture in Oshkosh, Wis. The RR500 turboprop engine is larger than the turboshaft RR300 launched last year and will deliver 350 to 450 shp. Based on the RR300 core, the RR500 features a higher mass flow compressor and correspondingly matching turbine, as well as an exhaust-down configuration, a gearbox and propeller controls.
