De Boeing 777 is een serie van widebodyverkeersvliegtuigen van de Amerikaanse vliegtuigfabrikant Boeing. Het vliegtuigmodel, dat tussen de 305 en 550 passagiers kan vervoeren, werd in 1995 in dienst genomen.
Hoeveel pk heeft een 777?
De motoren van de Boeing 777 staan voor 175.000 pk. Dit betekent dat dit toestel in slechts 6 seconden van 0 naar 96 km/u kan versnellen, waardoor ze als meest krachtige straalmotoren in het Guinness Book of Records staan.
Why Boeing-777 doesn’t have winglets?
Raked wingtips – Why Boeing-777 doesn’t have winglets? Boeing uses a desgin called Raked wingtips. Boeng 787, Boeing 767 and boeing 747- 800 uses the same design. All these aircrafts are capable of flying ultra long distance. This wing tip design is known as Raked wing tips.
Why doesn’t the Boeing 777 have a wingtip?
B777 was designed when the advantages of the wingtips were well known, yet they decided to go without one anyway. From airspacemag: Because winglets are a tradeoff: In the highly visible case of the 777, an airplane with exceptionally long range, the wings grew so long that folding wingtips were offered to get into tight airport gates.
What are winglets and how do they work?
In a cost-driven industry such as commercial aviation, winglets are a useful money-saving tool for airlines. These vertical extensions of an aircraft’s wingtips reduce the amount of aerodynamic drag caused by the aircraft as it cuts through the air. This drag is typically associated with the vortices that an aircraft’s wingtips create in flight.
What are the disadvantages of winglets in airplanes?
Another potential drawback to winglets is that of gate spacing at the ramp. Winglets can make for a much larger footprint at the gate. This could, in turn, make 5 airplanes without winglets into 2-3 planes with winglets, depending on spacing requirements and availability.
