Yesterday at NBAA Pratt & Whitney Canada lifted the veil on its 16,000-pound-class PW800 engine, which has been selected to power the new Gulfstream G500 and G600 large-cabin business jets, thus finding a new application for its PurePower family. The engine manufacturer (Booth 3240) said that the PurePower engine brings major improvements in fuel burn and maintainability. The program is well advanced, as certification of the new turbofan is expected by year-end.

News and issues relating to business aircraft turbine engines.
The strong investment Rolls-Royce has made in customer service was vindicated by the results of this year’s AIN Product Support Survey, which placed the engine maker in joint number-one position. Last year the engine maker established a new operational service desk in Dahlewitz, Germany, and made a series of reforms aimed at making its product service delivery team more responsive.
Microturbo is exhibiting an auxiliary power unit (APU) and an engine starter here at NBAA 2014 and also is developing two new APUs. Last summer, the Safran group company assumed full responsibility for two programs in which it was a minority partner: the APUs for the Dassault Falcon 5X and the Bombardier Global 7000/8000. Microturbo now wants to play a greater role in business jet APUs, including meeting the needs of future system architectures.
Snecma has confirmed the 11,000-lb-class Silvercrest turbofan has been flying since May on a modified Gulfstream II, after several delays. As another seven Silvercrests are running on the ground, the France-based engine manufacturer is still targeting late 2015 for certification. The first two applications are the large-cabin, long-range Dassault Falcon 5X and the super-midsize Cessna Citation Longitude, both twinjets.
Engine condition trend monitoring specialist Jet-Care is making its gas path analysis (GPA) available to operators of Pratt & Whitney Canada’s PT6 turboprop engines. The process detects deterioration and faults in the engine core by analyzing key flight data parameters, including fuel flow, shaft speeds and gas temperatures.
In tandem with the GPA service, Jet-Care also offers an array of laboratory services; analyzing oil, chips, filter debris, fuel and hydraulic fluids. These help to provide a fuller picture of an engine’s condition (see below).
There are now four Gulfstream G650 jets owned by Russian billionaires, but one of these is currently grounded as a result of U.S. economic sanctions against Russia. The aircraft in question is owned by oil and gas entrepreneur Gennady Timchenko, who was blacklisted earlier this year by U.S. government sanctions due to his close associations with Russian President Vladimir Putin.
GE Aviation has revised flight-testing plans for the Passport engine, chosen by Bombardier to power its ultra-long-range Global 7000 and 8000. The engine manufacturer initially planned to begin flight-testing the first development engine on its newly acquired 747-400 flying testbed (FTB) from facilities in Victorville, Calif., in July or August. Now the plan calls for the engine to fly on GE’s 747-100 FTB later this year or early next year.
United Turbine Parts (UTP) lays claim to being the world’s leading independent supplier of Pratt & Whitney Canada PW100 and PT6 engines and components. With Latin America having a growing fleet of aircraft powered by these turbine engines, the region is an important growth market for the U.S. company.
Pratt & Whitney Canada (P&WC) delivered the first production PW306D1 engine that will power Cessna’s new midsize Latitude twinjet, which is expected to achieve certification and commence deliveries in mid-2015. The PW306D1, a development of the PW306C/D engines that have powered the airframer’s Sovereign and Sovereign+ jets since 2004, is rated at a maximum takeoff thrust of 5,907 pounds and, according to P&WC, delivers the best thrust-to-weight ratio in its class, as well as higher thrust to climb and better overall specific fuel consumption than previous engines in the PW306 series.
Amelia Rose Earhardt, the pilot who earlier this month completed her namesake’s failed around the world attempt, will be a special guest of Pratt & Whitney Canada (P&WC) this week at EAA AirVenture in Oshkosh, Wis. Sponsored by P&WC, the present-day Earhardt flew a Pilatus PC-12NG turboprop, powered by the manufacturer’s PT-6 engine, more than 24,000 miles in 16 days, recreating the infamous 1937 global circumnavigation during which Amelia Earhardt and her navigator Fred Noonan disappeared.
