Gleaming on the Safran display (Stand 357) is a mock-up of the Snecma Silvercrest engine, which has been selected for the Cessna Citation Longitude super-midsize business jet. Displaying the model, which was first shown a few weeks ago at NBAA, underlines the fact that Silvercrest is now a program moving fast towards certification in 2015.

News and issues relating to business aircraft turbine engines.
GE Aviation’s new H75 and H85 turboprop engines received EASA certification yesterday. The two new powerplants are, respectively, 750-shp and 850-shp derivatives of the H80 engine, which is itself a derivative of the former Walter M601. FAA type certification of the H75 and H85 is expected next year. Last week, China Aviation Industry General Aircraft Co. (Caiga) selected the H85 to power its five-seat Primus 150 turboprop single.
HyperMach Aerospace announced a new configuration for its SonicStar supersonic business jet that will boost the aircraft’s top speed by more than 10 percent, to Mach 4.5, while also increasing range to more than 6,500 nm.
China Aviation Industry General Aircraft Co., Ltd. (Caiga) has chose GE Aviation’s new H85 turboprop engine to power its new Primus 150 aircraft. Set to be the first purpose-built executive single-engine turboprop built in China, the Primus 150 is a pressurized five-seater with an all-composite carbon-fiber airframe.
Pratt & Whitney Canada (Booth No. 3160) announced it has enrolled the 4,000th engine in its Eagle Service Plan (ESP) pay-per-hour maintenance program. The tiered program offers operators a choice of maintenance coverage. The basic plan includes parts and shop labor costs for scheduled engine overhaul/refurbishment and hot-section inspection, basic unscheduled engine and line replaceable unit/accessory maintenance and required product-support improvements at shop visits. Over the past two years the powerplant maker has added 1,000 new engines to the program.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility, near Paris. With 11,000 pounds of thrust, the Silvercrest will power the Cessna Longitude super-midsize business jet. EASA engine certification is slated for 2015 and FAA validation is expected shortly thereafter.
GE Aviation (Booth No. 3900) is planning on testing the first full Passport 20 engine, slated to power the Bombardier Global 7000 and 8000, in the second quarter of next year. The design of the 16,500-pound-thrust turbofan was frozen in April this year. A series of thorough safety trials is well under way.
Honeywell is targeting the third quarter of next year for the certification of the HTF7500E turbofan. This is a revised schedule that fits with Embraer’s delay in developing the midlight Legacy 450 and midsize Legacy 500 business jets.
Safran USA (Booth No. 2579) is flexing some considerable muscle here at the convention, showing a diverse role in the business aircraft market that stretches from nose to tail and wingtip to wingtip. Among the aviation products available from this global conglomerate are turbofan engines, nacelles, thrust reversers, landing gear, wheels and brakes, auxiliary power units, avionics, navigation systems, flight controls and wiring.
Pratt & Whitney Canada is here with the recently certified PT6A-140, the latest version of a turboprop engine that will celebrate next year the 50th anniversary of its first delivery. The -140 is will power Cessna’s new Grand Caravan EX turboprop single, with 867 shp at takeoff. That represents a 28-percent increase over the -114A used in the Grand Caravan. Transport Canada certified the -140 last July. The FAA’s equivalent approval is expected “in the next few months,” according to Denis Parisien, P&WC vice president for general aviation.
