Speed and flaps.
Flaps would increase drag increasing your speed will increase it even more
Drag if friend and foe of aircraft. it is created by wing flaps or feathering of propeller blades.
yes. the flaps increase drag which slows the plane down.
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
Because although flaps create extra lift they also produce a lot of extra drag which makes the plane inefficient.
Flaps increase the aerodynamic lift of a wing by increasing it's surface area. This allows the airplane to generate a greater amount of lift at slower speeds. In other words, when the flaps are extended, the airplane doesn't have to go as fast in order to take off or land. The flaps are retracted once the airplane is off the ground and has increased its speed to a point where the extra lift from the flaps is no longer needed. Flaps also have the effect of increasing drag on the airplane wing which reduces the airplane's speed and efficiency, but this only affects the aircraft when operating at higher speeds.
Drag slows the forward movement of aircraft.
Airplanes use a combination of slats and flaps in order to increase lift and increase drag. The slats are located on the leading edge of the wing and the flaps on the trailing edge. Flaps and slats when extended forward and aft increase the wing area which increases lift. When the flaps and slats are further extended they curve downwards increasing the camber of the wing which also increases lift. The greater the lift, the greater the drag. Deploy the flaps a little and lift overcomes the drag, fully extend them and the drag overcomes the lift. For takeoff the flaps and slats may be extended just a few degrees to increase lift. When flaps and slats are fully deployed in landing configuration, the lift is great but so is the drag and this in turn helps to slow down the airplane on decent to land.
The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.
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.
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
