Aviation Partners Boeing has launched the split-scimitar winglet program for the Boeing 737-900ER with an order from United Airlines. The carrier had already launched a similar program in January for its 737-800s, with FAA approval for a supplemental type certificate (STC) expected in October. The 900ER STC should be approved next February. The split-scimitar winglet modifies the existing blended winglet with a new cap section, and adds a ventral strake.
CFM International claims it is behind a revolution in the use of advanced materials for its Leap series of engines for single-aisle aircraft, that gives it a durability and maintainability edge over the competing Pratt & Whitney PurePower geared turbofan.
A Cessna CitationJet equipped with Tamarack Aerospace’s active winglets made an unofficial record-breaking trip from Sandpoint, Idaho, to Westchester County Airport in White Plains, N.Y., on Tuesday night. The Tamarack CJ (N86LA) is on display at today’s NBAA Business Aviation Regional Forum at Westchester County Airport in White Plains. The nonstop 1,853-nm flight landed with reserves of 472 pounds after flying for six hours and 16 minutes.
Aerion, which has been defining and refining its design for a supersonic business jet (SSBJ) for the past 11 years, is here at EBACE (Booth 7030) still quietly confident that it will someday be able to add the word “producer” to its résumé. To that end, a NASA F-15 has been flying this spring from Dryden Flight Research Center in California with an 80- by 40-inch section of Aerion airfoil attached to its belly.
Today at EBACE, Nextant Aerospace launched the $4.95 million 400XTi (the “i” stands for innovation) as the latest evolution of its remanufactured Beechjet. Compared to the 400XT, the new version introduces a number of improvements, including an all-new cabin that offers more space and reduced noise.
A Gulfstream G650 set a city-pair speed record last month on a flight between Shanghai and Newark, N.J., flying the 6,855-nm route in 13 hours and 32 minutes, the Savannah, Ga.-based aircraft manufacturer announced yesterday. The jet took off from Shanghai Hongqiao International Airport on April 18 carrying five passengers and four crewmembers. ATC restrictions kept the G650 below FL310 for the first hour before it was cleared to climb to its normal cruising altitude of FL410 to FL510.
In a Service Bulletin issued May 3, winglet manufacturer Aviation Partners (API) instructed operators with winglet-equipped 800-series Hawkers modified by STC#ST01411SE to reduce maximum permissible altitude to 34,000 feet. “Several instances of aileron/wing oscillations have been reported on the Hawker 800 [series],” the company said. “Aviation Partners and the FAA consider this Service Bulletin to be a safety-related limitation until a design change to preclude the oscillations is developed and FAA approved.”
To mark Learjet’s 50th anniversary, artist Princess Tarinan von Anhalt is using the engine thrust from a Bombardier Flexjet Learjet 40XR, in lieu of a paintbrush, to create new masterpieces today and tomorrow at Signature Flight Support in West Palm Beach, Fla. To create her latest artwork, von Anhalt is hurling paint into the engine exhaust–a force of approximately 3.5 tons–while standing 50 feet between the aircraft and the canvas.
Loss of control in flight related to the inability to recognize an upset and controlled flight into terrain remain the primary causes of accidents involving transport aircraft.
Researchers at the German Aerospace Center (DLR) in Göttingen may have discovered a way to make helicopters more maneuverable, by reducing the dynamic load on the rotor head control rods.
During rapid forward flight or maneuvering, airflow stalls on the main rotor blade as it retreats (moves backwards), giving rise to a “dynamic stall” and subjecting the rotor head control rods to formidable dynamic loads.
