Following delivery last week of the first 787-9 rudder built in China by Chengdu Civil Aviation (CCAC), Boeing extended its supply chain further for yet another airfoil subassembly, choosing the UK’s GKN Aerospace to build the winglet for the 737 Max. GKN joins Korean Air Aerospace Division (KAL-ASD) in South Korea as co-supplier of the raked, dual-feather-design winglet.
The first Learjet 28 Longhorn (Serial Number 28-001) cruised at 50,000 feet somewhere between Allentown, Pa., and Mattoon, Ill., when the thought hit me. The late Neil Armstrong, the first man to walk on the moon, had flown this same airplane and here I was riding in the cabin.
The Bombardier Learjet 75 light jet–a longer-range version of the Learjet 45 with Garmin G5000 integrated avionics, winglets and more efficient Honeywell TFE731-40BR engines–received FAA certification on Thursday. Deliveries have already begun for U.S. and Canadian customers, a Bombardier Aerospace spokeswoman told AIN. Certification and delivery efforts are pending for its smaller sibling, the Learjet 70.

Aviation Partners Boeing last month announced that, after launching on the Boeing 737 NG, split scimitar winglets can now be fitted on the Boeing BBJ family. The new split scimitar winglets offer a significant reduction of drag compared to the non-winglet-equipped Boeings and a noticeable drag reduction for those equipped with Aviation Partners Boeing blended winglets.
Boeing said it has completed aerodynamics, engine and weight audits that together have given it a clearer picture of the future operating performance of the new 737 Max. The manufacturer now says the re-engined narrowbody will burn 14 percent less fuel than today’s 737-800NG, one percent better than it previously estimated.
Two faculty members from Penn State’s vertical-lift research center of excellence were honored recently at the fourth annual International Basic Research Conference on Rotorcraft Technology in Tianjin, China. Professor Edward Smith and research associate Jianhua Zhang were honored for their paper, “Influence of Aeroelasticity Tailored Wing Extensions and Winglets on Whirl Flutter Stability.” The research was underwritten by the National Rotorcraft Technology Center and the NASA Ames Research Center.
Boeing has increased its estimate of the operating performance of the 737 Max, saying the re-engined narrowbody will burn 14 percent less fuel than the current 737NG consumes. In July, the manufacturer said the 737 Max with new CFM Leap-1B turbofans will be 13 percent more fuel efficient.
Aviation Partners (Booth No. C8114), in cooperation with Boeing, is launching its new Split Scimitar Winglet program for Boing BBJs. Split Scimitar Winglets are already available for 737 NGs.
The Split Scimitar Winglet modifies the existing blended winglet on the BBJ by adding a Scimitar-tipped ventral strake, reinforced internal winglet structure and replacement of the aluminum winglet tip caps with more aerodynamically shaped Scimitar tip caps.
Tamarack Aerospace and Cessna Aircraft signed an agreement this week at NBAA 2013 under which Cessna will market, sell and install Tamarack’s active winglets for the CitationJet family through the CJ3. The winglets provide more range, increased useful loads and improved high-and-hot performance, while simultaneously improving fuel economy.
