What is a Boeing 737-800 winglets?
What is a Boeing 737-800 winglets?
The most noticeable feature to appear on 737s since 2000 are winglets. These are wing tip extensions which reduce lift induced drag and provide some extra lift.
Is a 737-800 winglet a max?
On some 737-800 NG Variants you’ll see a little winglet going downwards from the ‘L’ shape. You can tell it’s not the Max, as the little winglet will look like an ‘addition’ almost as if it was an afterthought. Like it’s out of place, unlike on the 737 Max, where the whole winglet is one big shape.
What is the wingspan of a 737-800 with winglets?
117 ft 5 in
| 737-700 | 737-800 | |
|---|---|---|
| Length | 33.6 m (110 ft 4 in) | 39.5 m (129 ft 6 in) |
| Wingspan | 35.8 m (117 ft 5 in) | 35.8 m (117 ft 5 in) |
| Height | 12.5 m (41 ft 3 in) | 12.5 m (41 ft 3 in) |
| Engine | CFM-56 | CFM-56 |
What is the purpose of winglets?
Winglets are vertical extensions of wingtips that improve an aircraft’s fuel efficiency and cruising range. Designed as small airfoils, winglets reduce the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air.
Why are 737 wing tips bent?
Although planes can fly without them, the curved wing tips play a vital role in keeping travellers safe, lowering emissions and reducing noise pollution along flight paths.
Is Boeing 737 800 winglets the same as Boeing 737 MAX 8?
The main differentiator between the 737-800 and its Next Generation sibling is the engine type that each one uses. While the 737-800 primarily uses the CFM56, the Max family of aircraft are powered by the CFM LEAP 1B aircraft.
How do winglets work?
Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane’s wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls upward around it.
How does a winglet work?
How do winglets save fuel?
Winglets reduce drag and increase lift at the end of the wings, where the physics of flight create small tornadoes. Winglets essentially reduce the size of those whirling air masses and improve the plane’s “gas mileage” by helping jets more efficiently slice through the sky.
