can airplanes float in the air or like park???/?

Answer 1

enough with the mushrooms, are they back or something?

Answer 2

Some types can hoover indeed but "parking" is not possible. You know that for as long as you are up there, the gravity wants you to come down. There are two different ways to compensate this: By creating a lift force from your wings, or having a thrust vector opposing the gravity force.

Creating lift is the normal way for fixed wing aircraft to fly. The speed generated by the engines, causes an airstream over the wings, inducing lift. Lift force must be equal to the weight of the plane in order to maintain altitude. So without speed you can not maintain your altitude

Unless...
You have a thrust vector, compensating the weight. This works as following:
If we take the Harrier as an example... the pilot can change the position of the engine exhausts with about 120 degrees if I'm right. If he selects 90 degrees downward, his full thrust power is aimed in opposed direction to the gravity. Engines are used to produce the acceleration of the aircraft, so if the generated acceleration is exactly equal to the gravity acceleration they eliminate each other. Then the plane is hoovering, but a plane can never "park" in the air, because as soon as the opposing force to the gravity disappears, it goes down.

If an aircraft has to wait in the sky, for example on a clearance to land, they fly a holding pattern (like a race circuit but then in the shape of an 0). circling around till they can continue.

Answer 3

Some jets or prop planes can "hover", but at great fuel cost. There are none that can park, or stay there without expending great energy to do so. Several that can manage some slow or no-speed motion as follows :

- Harrier jump-jet

- V-22 Osprey ( boeing )

- vintage Custerwing ( props inside curved wing, slow speed high lift flight possible )

- vintage Gyroplane, which was a converted bi-plane or monoplane with helicopter-type rotating blades, could hover in a wind, and do almost vertical landings on building tops in the 1930's.

The CLOSEST to what you're talking about would be an Ultralight type powered parachutes, which can sometimes hover in light winds while being pushed with a small engine. Closest thing to what you describe, but there is no true parking ( which implies no power ). Only a blimp can do that, and it will drift with the wind currents.

Answer 4

"Float in the air or like park"? What do you mean by that? Are you referring to hovering? No offense, but you sound very ignorant. The answer is NO, they most certainly cannot hover or "float" in the air. The wings must keep moving forward at a minimum speed (called a stall speed, it's different for every type or airplane), in order to produce enough lift to stay airborne.

Answer 5

Seems to me the people trying to make you feel dumb are pretty ignorant. Yes, I say again for clarity yes, any airplane can float in mid air given the right conditions.

Airplanes stay in the air because of a force called lift that pulls them up off of the ground. Lift in an airplane is created by air flowing over the wings (gyrocopters, helocopters, blimps, baloons and flying saucers are not airplanes as airplanes have functioning lift generating wings). Just how fast the air has to go depends on the shape of the wing and the weight of the airplane.

Lets take an airplane for an example. A Cessna 152 is a small 2 seat single engine airplane that can fly around 100 mph. To produce enough lift to stay in the air a Cessna 152 needs the air to pass over the wings at around 45 miles per hour. Normally the engine pulls this airplane through the air at or faster than 45 miles per hour and so it stays in flight. Now suppose this airplane is flying along at 50 miles per hour in calm air. Suddenly the wind picks up and is pushing against the airplane at 50 miles per hour. The air is pushing against the airplane at the same speed the airplane was going, so the airplane will literally hover over the ground. This is no different than running on a tread mill. Your feet are still moving at a pace that might move you at 5 miles per hour, but the floor beneath you is moving backwards at the same speed. As far as the wings of the airplane are concerned the air is still flowing over them at 50 miles per hour and they are still providing enough lift to keep the plane in the sky.

In larger commercial aircraft this is going to take hurricane force winds, but it can happen. Heck, give a strong enough wind and a small enough plane and you can fly backwards.

If anyone doubts me and has flight sim, load it up and give yourself a crazy 250 MPH headwind. Watch that 747 levitate.

Answer 6

An airplane can glide through the air but not float. If a plane stops in mid air then there is no more lift produced by the wings and so the plane would consequently fall.

Answer 7

You might laugh at this, but yes. Small, general aviation aircraft have been known to "hover" if they fly into a strong enough headwind. For instance, a Cessna 150 has a top speed of around 110 knots, and cruises at around 90 or so. It's fairly common for pilots in aircraft like this to see cars passing them on the highway if they're flying into a headwind.

As for the hovering, it has to do with stall speed. Some new Light Sport aircraft have stall speeds so low that a 40 knot wind will literally create enough lift to make the airplane lift off.

As for trying this for yourself, I don't recommend it. The wing might have enough lift to get you airborne, but you will have almost zero control authority and you will almost certainly crash. So, to answer your question, can an airplane "hover", yes, under the right conditions. Should the pilot attempt this? NOPE.

Besides....Harriers have been doing it for decades now.

Answer 8

Yes. A VTOL (Vertical Take Off and Landing) jet fighter can do that. It can take off from a launch pad and hover straight up and park there if it wants to. The U.S. has a jet fighter plane called a "Harrier." That is a VTOL aircraft. There was a Sylvester Stallone film in which he flew one and blew up bridges and bad guys with it.

Also, I'm a hang glider pilot. The stall speed of my hang glider is about 20 miles per hour. If I'm flying into a 20mph headwind, I am parked. I have zero ground speed.

Answer 9

well think about it an air plain has a propeller in the front that makes it move by pulling or poshing it forward. the wings are positioned so the wind will push it up. and the engine will stall if it goes straight up or under 40 to 25 mph depending on the plain. it is the Same thing with a jet engine. now... think about it and. it isn't that hard to figure out. however there is an air plain called the Auto Giro that has a propeller in the front and on top like a helicopter. the military used it as an air plain sniper rifle. it couldn't hover but it could easily be out ran by a runner. it is no longer in use because of it's gas millage

p.s. i am only 13 how does that make you feel and like
i would have like been nicer if you like didn't talk like Paris Hilton

Answer 10

No. A true airplane must be moving thru the air so the wings can develope lift to keep the aircraft flying and not falling to the ground.

Answer 11

Yes, The VSTOL (Vertical Short Take Off and Landing) AV-8B Marine Corps attack aircraft is an example. The new Joint Strike Fighter will also have a VSTOL variant.
