Aeroplain stand still in air?

Question

how aeroplaintake take on & take off

Answer 1

Technically, depending upon the type of airplane and speed of the head wind, a plane can "hover". As long as air moves over the surface of the wing fast enough to create enough lift to make the airplane fly, it will fly--it just may not have very much forward speed.
Why does an airplane fly? The Bernoulli principle. Air flowing around the wing does so at two different speeds due to the shape of the airfoil. It flows around and over the top more quickly than along the flat bottom of the wing. This creates higher pressure on the bottom pushing up. As long as there is enough push to overcome gravity (or weight), the plane will fly. You might ask, then without moving forward and in no wind, how does a helicopter fly? Well, its airfoils are always moving through the air as long as it is running--the rotors are its wings.

Answer 2

Well since we have a lot of smart people answering this....airplane is the accepted spelling by the United States standards. Aeroplane is an accepted spelling elsewhere in the world.
Now to answer the question - there are four principles to flight THRUST - LIFT - DRAG - GRAVITY

The wing is flat on the bottom, curved on the top with the leading (facing the wind) edge thicker than the trailing edge. This makes wind flowing over the wing to move different than the wind under the wing. As the wing meets the air it slices the wind in half. Half goes over the wing, half goes under. Now it has to reach the trailing edge at the same time, so air over the wing moves faster than the air moving under. A physical property is that faster moving air gives less pressure than slow moving air, so this is where lift comes in. If LIFT is greater than GRAVITY the plane will rise in the air. The rotary wing on a helicopter allows it to rise and hover. Tilting the rotary wing makes the copter go in the direction of tilt. Planes have stationary wing. So to generate lift you need a propeller to produce thrust or a strong enough wind blowing against the plane from the front. So a plane flies when lift overcomes gravity, and thrust overcomes drag.

Answer 3

The motion of an aircraft through the air can be explained and described by physical principals discovered over 300 years ago by Sir Isaac Newton. Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666, when he was only 23 years old. Some twenty years later, in 1686, he presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis." The laws are shown above, and the application of these laws to aerodynamics are given on separate slides.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.

The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:
F = m * a

For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.

The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine.

Answer 4

An Aeroplane cannot stand still in the air. Try using spell check next time before you post your question, that will save you from getting all of the smart alec comments Have a great day!!

Answer 5

Clearly Gunz has no clue as to how an airplane flies. As for an Aeroplain, he might be on the right track!

PHEW! Thanks Logic for that lesson on international spelling rules. And, since you're such an expert on the subject, where do they spell it "Aeroplain"?

Answer 6

What the heck is an aeroplain? An airplane on the other hand can fly.........wheeeeeeeee.

Answer 7

simple saying..yes it can as if you use propellers firing blasts in all directions im sure that it could remain in ne place at any given point of time...

Answer 8

if 'AEROPLANE'S' were still then chances are they would fall out of the sky... but if they lowered themselves out of the sky onto the floor and then braked it could work. it's too early for this!!

Answer 9

back to school and learn how to spell airplane not Aeroplain

Answer 10

if you can type a question why are you so dumb?
