Turboprop-engine manufacturers continue to develop technologies in anticipation of future demand for new or derivative regional airliners designed to carry approximately 90 passengers, a step up from contemporary aircraft offering around 70 seats. By January 1, Pratt & Whitney Canada hoped to have completed the first phase of a next-generation regional turboprop (NGRT) demonstration program intended to validate characteristics for a main centrifugal compressor. Meanwhile, U.S.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility near Paris, France. With 11,000 pounds of thrust, two of the units will power the Cessna Longitude super-midsize business jet.
HyperMach Aerospace announced a new configuration for its SonicStar supersonic business jet (SSBJ) that it claims will boost the aircraft’s top speed by about 12 percent to Mach 4.5, while increasing range by 500 nm, to 6,500 nm. At its planned high-Mach cruise speed of Mach 4.4 at FL620, the SonicStar would be able to fly from New York to Dubai in only two hours and eight minutes.
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.

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.
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.
Joined by top U.S. transportation officials, Boeing and American Airlines showcased the 737-800 “ecoDemonstrator” flying testbed at Washington Reagan National Airport on September 18. Boeing had flown the aircraft from its flight-test facility at Glasgow, Montana, the preceding day using a biofuel blend made partially from used cooking oil.
General Electric and Rolls-Royce tie for first place among turbofan manufacturers, each scoring an overall average of 8.0 for the quality of product support they provide their customers. Compared with last year, that score represented an improvement of 5 percent for GE and 1 percent for R-R.
GE has finished the first round of checks on all in-service and spare GEnx turbofans ahead of the September 21 publication of a U.S. Federal Aviation Administration airworthiness directive (AD) that calls for ultrasonic inspection of early-build engines’ fan midshafts every 90 days. GE has developed a field ultrasonic method to inspect the suspect area of the engines while they remain on the airplanes.
