What makes aeroplanes to fly?

Lift. The shape of airplane wings (curved on top, flat on bottom) allows air to pass over them at different speeds, creating a pressure gradient. Higher pressure is built up underneath the wing, allowing for lift to carry it off the ground. For this to work, the airplane must maintain a minimum rotation speed to get off the ground (in a Cessna 150, that speed is about 90mph). Once in the air, the plane can reduce its speed and often glide, however when an aircraft looses too much speed, it looses lift and stalls out.

The same reason airplanes do. Its a matter of lift and drag, based on the shape of the wing. A frisbee is just a circular wing.

I know they had some flying toys as kids - i.e. rubber band helicopter sort of things. Also it was sort of a craze at the time, google early aviation history or equivilent and you should be able to find some videos and other info.

All thing that flies except aeoroplane.

well, it's the area of the wing of the lifting surface, the weight of the plane, along with the pitch angle witch can be adjusted to generate more down force, but a high pitch angle would cause the plane to stall and maybe crash, also the altitude; planes can fly slower at lower altitude because the air is more dense there which means that less speed can generate enough life for it to fly..

Forces Acting on An Airplane\nThere are four forces acting on the airplane all the time during airplane is flying.The four forces are\n(1) Lift, (2) Gravity force or Weight, (3) Thrust, and (4) Drag.\nLift and Drag are considered aerodynamics forces because they exist due to the movement of the Airplane through the Air.\nWeight: The weight acts vertically downward from the center of gravity (CG) of the airplane.\nThrust: is defined as the forward direction pushing or pulling force developed by aircraft engine . This includes reciprocating engines , turbojet engines, turboprop engines.

Earth is around, you know that. An aero plan has to fly around and it would be flying thousands of kilometers away from you.\n\n It would appear that the plane is flying so slowly. But if you see an aero plane that is flying on low altitude that would appear to be faster.\n\nSky is so wide, you can see larger area if you look further and further you can see more wide angle. \n\nIt is not same as if it is closer to you, the distance would be very small. If it is far distance is greater.

An airplane wing is designed so that air travels slower under the wing. This increases, the pressure under the wing, giving the plane lift.\n\nReally it should be that the air travels *faster over* the wing, which*decreases* the *pressure above* the wing, giving the plane lift.

More than Bernoulli's principle and wing shape (airfoil) are at work in keeping a plane in the air. The main criteria is the  "angle of attack" of the wing. That is, the angle at which the wing meets the air passing by it. When a plane is flying, its wing is always at a positive angle of attack; the leading edge of the wing is higher relative to the air going over it than the trailing edge. So the air pushes the wing up.  When the plane is inverted, the angle of attack must be great enough to overcome the "negative lift"  created by the airfoil. This is accomplished by adjusting the elevator. Inverted flight will always require the input of down elevator.

The German's had lots of experiemental aircraft during the war, but there are only a few that flew during the way.  ME-162 Komet, and the ME-262.\n\nThere were plans for a "flying wing", but no flying saucer.

flies can set in motion the wings 200 times/sec....\nso,flies can fly very-very fast, that is 300mil/hour or 50 kilometres/hour

Probably check out a hobby store that may have models that meet your needs.  \n\nThere are simple planes made of balsa or heavy paper you could make from scratch (without a kit).  It just depends on your skill level, ambition, and what you need it for.

depends on your definition of flying, which is commonly known as moving through the air using wings or an engine, but good question though. but IMO flying is controlled falling :), since if you look at the physics of it, you are constantly trying to counter gravity which is towards the center of the earth.

Through Lift\n\n\nGeneral Concept: \nThe force of the air on the wings of a plane can be thought of as divided into two components: a component pushing the plane up and a component pushing the plane back. The upward force, the lift force, is what keeps the plane in the air. The sideways force that slows the plane down is called drag. So even though lift and drag are different words and are talked about differently, they both come from the same air hitting the plane... think about that! The pilot can change the lift force too: getting a lot of lift at takeoff (needed to accelerate the plane upward), and less lift during cruise (just need to overcome the weight of the plane).

Lift force depends on wing area, angle of attack, air density, airspeed, and several other parameters.  Google "aerodynamic lift" and see.  Happy landing.

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.\nWhy 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.

It needs air to fly.  However, it can use very thin air.  One idea for using the space plane is to fly it out of the atmosphere, where its engine will cease to function.  The plane then glides as far as it can outside the atmosphere.  As it begins loosing altitude (because it is on a suborbital trajectory) it reenters the atmosphere and the SCRAM jet engine will work again.  It keeps skipping across the top of the atmosphere this way until it reaches its destination.\n\nThis trick saves a lot of fuel because aerodynamic drag is minimal while the plane is outside the atmosphere.
