Southeast Turbines has completed renovating its 10,000-sq-ft facility at Fort Lauderdale Executive Airport. The FAA-certified repair station specializes in the Pratt & Whitney Canada PT6A, PT6T and JT15D. Southeast Turbines’ capabilities include on-wing hot-section inspections, compressor-turbine disk reblade, true and balance, small exit duct rework to include “zero grind” hot-section installations, unscheduled power section repairs, fuel nozzle cleaning/recertification and bleed valve overhaul.
Bell Helicopter has tapped Honeywell to provide the auxiliary power unit (APU) and environmental control system for the new Bell 525 Relentless, which is scheduled to start flying next year. The Honeywell RE100 APU selected for the super-medium twin helicopter is lighter and more fuel efficient than competing systems, according to Honeywell. Honeywell’s AC-5510 environmental control system will provide heating and air-conditioning for the 16-passenger helicopter.
The U.S. military cleared the F-35 Joint Strike Fighter to return to flight on Thursday, ending a week-long cautionary grounding that was ordered after an engine inspection revealed a cracked turbine blade on an F-35A test aircraft at Edwards Air Force Base, Calif.
Many cockpit crewmembers believe the ingestion of ice crystals by a jet engine is essentially harmless if the engine’s igniters are turned on. However, aeronautical engineers generally do not agree, citing incidents when mixing ice with standard intake air resulted in a noticeable reduction in engine power output and, at its worst, a complete engine flameout. Ice formation inside an engine compartment can also lead to indicator anomalies that may not shut down the engine, but may lead to air data system failures.
The U.S. military grounded its fleet of Lockheed Martin F-35 Joint Strike Fighters after a routine engine inspection revealed a cracked turbine blade in an F-35A based at Edwards Air Force Base, Calif. The precautionary flight suspension was announced on February 22, following an inspection earlier in the week. The grounding affects all three variants of the fighter, for a total of 51 aircraft.
In a widely unexpected move, Embraer has switched partnership alliances from GE to Pratt & Whitney with its choice of the Geared Turbofan to power the next generation of E-Jets. The decision, announced last Tuesday, gives Pratt & Whitney its fifth application for the engine line also known as the PurePower PW1000G, and leaves Boeing as the last of the four major Western airframe manufacturers not to have adopted the design.
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.
