What is a winglet? A plane normally has Wings along with tier control surfaces. The horizontal stabilisers with their control surfaces, they are the bits that look like wings on the tail. Then there is the one that points up into the air with its control surfaces which is the vertical stabiliser. If any one of these falls of you are in dire need of a parachute unless you are on the ground.
Winglets increase the fuel efficiency of aircraft that have them.
Winglets are not absolutely required but many planes have winglets added to improve the aerodymanic efficiency of the wing.
Winglets increase an aircraft's operating efficiency by reducing induced drag at the tips of the wings
There were no airplanes in 'the gilded age'.
They are important because if we didn't have them then we wouldn't be able to ride in airplanes. Airplanes are used for many important things such as shipping goods, transporting people, and in war and without pilots their would be no airplanes flying.
to reduce drag
Usually control surfaces, like ailerons, flaps, slats, air breaks, on the wingtips you sometimes see winglets. On many airliners the engines are also attached to the wings. On military airplanes you can find external fuel tanks and weaponry.
They are called winglets, the main function of the winglets is to reduce drag. Reducing drag increases speed and decreases fuel consumption, thereby extending range and saving money.
Aircraft have been an important part of transportation ever since they were proven.
Thrust vectoring. The winglets are there for stability - if they were to try placing ailerons on the winglets, they'd likely be unable to withstand the force exerted on them by the missile moving at speeds of over Mach 2.
The invention of airplanes was so impotant because it could travel farther and faster and it became a new level of fighting in war.
Have a large wingspan and and to throw it from the center of balance.
