sing this and hope it happens:
Jingle bells, Jingle bells
Jingle all the way
Oh what fun,
It is to ride,
In a one-horse open sleigh
Hey! (x2)
Dashing through the snow
On a one-horse open sleigh,
Over the fields we go,
Laughing all the way
Haha!
Bells on bobtails ring,
Making spirits bright,
What fun it is to laugh and sing
A sleighing song tonight,
(Oh! )
Jingle bells, Jingle bells
Jingle all the way
Oh what fun
It is to ride
On a one-horse open sleigh
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
Flaps are used on aircraft to increase the wing area of the plane and therefore increase lift and reduce speed.
lift = 1/2 air density x velocity squared x surface area
Induced drag is caused by the creation of lift on an aircraft's wings. As the aircraft generates lift, it creates vortices at the wingtips, which result in a rearward force component known as induced drag. This drag increases as the angle of attack or lift produced by the wings increases.
The two forces that help overcome gravity are lift and thrust. Lift is generated by the wings of an aircraft, providing an upward force that counteracts gravity, while thrust is produced by engines to propel the aircraft forward, allowing it to achieve lift and ultimately overcome gravity.
In aviation, thrust is the force along the axis of the aircraft which moves it through the air. Together with drag, lift and weight, it is one of the four forces required to make an aircraft fly.
The lift, drag, thrust, and weight formula used in aviation is a way to calculate the forces acting on an aircraft during flight. It states that lift must equal weight and thrust must equal drag for the aircraft to maintain level flight.
During landing, the purpose is to slow down the aircraft's ground speed as slow as you can without it stalling. You want to maintain Lift, not necessarily get more lift. At higher speeds, the aircraft has plenty of Lift. However during landing, the speed is slower and the angle of attack is increased to provide more Lift at lower speeds.
Downthrust is a term used in the context of propellers or rotors, referring to the force they generate that pushes an object or aircraft in the downward direction. This force helps to counteract the lift force produced by the wings and keep the aircraft stable during flight, preventing it from climbing uncontrollably. It is crucial for maintaining the aircraft's altitude and overall stability in the air.
When the flaps are lowered during takeoff and landing, the lift force is increased. This is achieved by increasing the wing's surface area and altering its shape, allowing the aircraft to generate more lift at lower speeds. The enhanced lift helps the aircraft become airborne more easily during takeoff and provides better control and stability during landing.
Interesting question. Lift is what actually allows an aircraft to leave the ground, but lift in a normal type aircraft (not a helicopter) is generated by forward movement through the air and that is produced by thrust. So, while lift is what's necessary to overcome gravity (weight), it's thrust that is needed to generate lift...so both forces are in play at takeoff.
The pulling force on an airplane during flight is known as lift, which is generated by the wings as the aircraft moves through the air. Lift is created by the pressure difference between the upper and lower surfaces of the wings. The amount of lift produced is influenced by factors such as airspeed, angle of attack, wing shape, and air density.
