Increasing an airplane's speed or wing size does which of the following?
Generates more lifting force
As air molecules move over and under wings of an airplane the pressure increases below the wings to create which of the following?
Lift
How does bernoulli's principle affect lift?
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. In the context of lift, air flowing over the curved top surface of an airplane wing travels faster than the air below the wing, creating lower pressure on the top surface. This pressure difference generates lift, allowing the airplane to stay airborne.
What is the device in an aircraft wing to reduce lift and decrease speed?
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.
Why are airplane flaps not used at cruising speeds?
Airplane flaps are used during takeoff and landing to increase lift and drag, which helps the plane to reduce speed for landing and take off. At cruising speeds, the airplane is already flying efficiently and has no need for the extra lift and drag provided by the flaps.
What does airplane swing contribute to the lifting force force on an airplane?
When the wing is straight it creates more 'lift' . When swept it allows more speed.
How could you increase lift on an airplane's wings?
increase the angle of attackOr speed up the airflow across the top
What is affected by an airplane's speed?
Airflow ans lift over the airframe is affected by the airplane's speed.
What happens if thrust greater than drag in airplane?
When thrust is greater than drag in an airplane, the aircraft accelerates forward. This occurs during takeoff or when the pilot increases engine power. As the speed increases, the airplane generates more lift until it reaches the necessary speed for flight. Ultimately, the surplus thrust allows the aircraft to climb or maintain a higher speed.
What are the purposes of the slats and flaps of an airplane's wings?
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.
How could you make an airplane rise faster into the air?
Increase speed and/or lift. You want the pressure above the wing to be lees than below. In very short times like takeoff, the flaps are increased to sacrifice speed for lift. As the a/c speed increases the flaps are slowly retracted until the wing is at its optimal setting. (Flaps moving is that mechanical noise you hear during takeoff and landing).
How does an airplane achieve lift?
The speed of air over and under the wings creates pressure which is lift.
Increasing an airplane's speed or wing size does which of the following?
Generates more lifting force
How do flaps increase lift on an airplane?
Basically they 'curve' the wing, forcing the airflow to lift more weight.
What happens when your Increasing an airplane's speed or wing size?
Greater lift
As air molecules move over and under wings of an airplane the pressure increases below the wings to create which of the following?
Lift
What happens if the Thrust is greater than drag on an airplane?
If thrust is greater than drag on an airplane, the aircraft will accelerate forward. This surplus thrust allows the plane to gain speed, which is essential for takeoff and climbing. As the speed increases, the lift generated by the wings also increases, enabling the aircraft to ascend. In essence, a net positive thrust leads to improved performance and maneuverability.
