If you walk around the static display here at MEBA 2012, a common theme emerges: there are hardly any airplanes on show that do not have upturned wingtip extensions.
Aveo Engineering Group, a multinational company headquartered in the Czech Republic, has gained FAA TSO C30c and C96a certification for its Ultra Galactica series of two- and three-function wingtip lights, as well as its Red Baron anti-collision beacon for aircraft. The company says it is now in the process of receiving STCs for Hawker jets and aircraft built by Cessna (singles and twins), Mooney, Cirrus, Piper and Robinson Helicopter.
Whelen Engineering (Booth No. 2789), a privately held company based in Chester, Conn., has been manufacturing aircraft lighting for more than 60 years. At this year’s NBAA Convention the company announced that it was chosen to be the supplier for the LED wingtip lighting on the Cessna Citation Sovereign block point winglet upgrade program. The wingtip unit incorporates both anti-collision and position lights using low-draw, extra bright and reliable LED technology. The product is TSOed as a line-replaceable unit. –A.L.
The National Transportation Safety Board (NTSB) has recommended that the FAA require manufacturers to equip large airliners with onboard, externally mounted cameras to offer pilots a clear view of the airplane’s wingtips while taxiing. The September 5 recommendation is a first step toward ensuring clearance from other aircraft, vehicles and ground obstacles.
The design window “is closing” on the final configuration of the re-engined Boeing 737 Max narrowbody airliner.
Boeing unveiled a new “advanced technology winglet” design for the 737 Max on Wednesday, saying that it will provide up to an additional 1.5-percent fuel-burn advantage on top of the 10- to 12-percent improvement already advertised for the re-engined narrowbody.
BLR Aerospace’s latest product, winglets for the Hawker Beechcraft King Air 90 series twin turboprop, received certification in March by authorities in the U.S., Europe and Brazil. The new winglets are currently available for all King Air C90A, C90GT and C90GTi models. BLR expects to receive certification shortly for a winglet package designed to fit earlier King Air C90 and C90E models as well.
More than 200 Gulfstream II and Hawker 800/800XP business jets now sport blended winglets developed by Aviation Partners (Stand No. 925) to improve performance by reducing time to climb and fuel consumption, or by increasing range.
They also can enhance the perceived value of an aircraft, according to the U.S.
company’s senior vice president of marketing, Dick Friel.
Conventional winglets have come to be widely used on airliners, whether in the form of the Airbus A320’s wingtip fence or the up-swept devices characteristic of the A330/340 and Boeing 747-400. And if winglets are good, shouldn’t bigger ones be even better? Wingmaker Airbus UK has been investigating their potential.
Winglets increase efficiency by reducing lift-induced drag. They do this by relocating and diminishing the vortex at the wing’s tip, resulting in lower fuel burn, higher cruise speed and longer range.
