The McDonnell Douglas MD-11 was the first aircraft with split-tip winglets in 1990. For the 737 Next Generation, third-party vendor Aviation Partners has introduced a similar design to the 737 MAX wingtip device known as the split scimitar winglet, [34] with United Airlines as the launch customer.

The winglet and red navigation light on the wing tip of a South African Airways Boeing 747-400 Many aircraft types, such as the Lockheed Super Constellation shown here, have fuel tanks mounted on the wing tips, commonly called tip tanks The wing tip of a Quad City Challenger II, formed with an aluminum bow The wing tip of a Grumman American AA-1, showing its Hoerner style design A Piper PA-28 ...
Wingtip vortices can pose a hazard to aircraft, especially during the landing and takeoff phases of flight. The intensity or strength of the vortex is a function of aircraft size, speed, and configuration (flap setting, etc.).
The Learjet 28/29 was the first production jet aircraft to utilize winglets [5] (entering service in 1977). Both models were commercially unsuccessful, showing reduced range compared to the Learjet 31, as the addition of winglets required the deletion of the earlier model's wingtip tanks, and they sold mainly to customers with a requirement for ...
The winglets improve fuel efficiency by five percent and increase range by 200 nautical miles (370 km; 230 mi) through the reduction of lift-induced drag. [87] [88] Continental Airlines was the first carrier to order winglets for the 757-200, and in February 2009 became the first operator of 757-300s with winglets. [89]
A winglet is a short fin that projects upward from the wing of an aircraft. They are used to reduce aerodynamic drag. CNBC has requested comment from a spokesman from Trump’s presidential ...
The agreement was for 26 aircraft, of which 20 were eventually produced along with two MD-90 aircraft. [22] Upon cancellation of the co-production program, China refused to return the tooling used to McDonnell Douglas, and subsequently used it and the fuselage cross-section design in what became the Comac ARJ21 regional jet.
The plane was born out of a competition between Boeing and North American Aviation, then a major aerospace manufacturer that was eventually chosen by the Air Force, in 1957, to develop a bomber ...
