Harrier jump jet.

2007-12-05 00:42:29 · answer #1 · answered by Anonymous · 0 3

Some model aircraft with good power to weight ratio can balance in the air pointing vertically. This can be done in a lifesize aircraft just yet.

If the airspeed is strong enough, i.e. the wind, the aircraft could fly into it and technically won't have any ground speed. This isn't recommened very often because if the wind suddenly dies....

VTOL aircraft such as the harrier jump jet and the they can balance in the air, although this is only possible when they are close to the ground.

The only time I have seen such thing was with an RC Plane. The head wind by pure coincidence, was as fast as the speed of the plane at full throttle. The airplane took off straight up like a helicopter and landed back pretty much on the same spot. Was pretty funny to watch.

The other ones mention here are applications of vectorial thrust like the Sukhoi Su-37 Thrust Vectored Control (TVC) fighter and the Harrier.

VTOL (Vertical Take Off and Landing) planes like the McDonnell Douglas (Boeing) / BAE Systems Harrier Jump Jet can hover.
Technically, a conventional fixed-wing aircraft can stay in mid-air without moving, but I doubt it's been tried or being planed to do in the foreseable future.
It's only possible with a 200knots head wind.
You'll have to fly into a hurricane!!!!

Forget what everyone is saying. Is it possible yes it is. What makes a plane fly air speed around the wings. That said thrust only provides horizontal spead that creats wind for lift. In theory if the plane had head winds of about 160 around the spead most planes take of at the plane will lift of of the ground. The plane will be pushed backward too. if added enough thrust to counter the wind the plane will be in the air but not moving. This is entirely possible but the circumstanses that it would happen under would almost never happen. i have tried this in flight simulator it works. so dont let anyone say it doesnt.

The correct answer is yes. Small piper or Cessna aircraft will stall in the 45 to 55 kt range. It is not uncommon to have a wind blowing at this speed, especially at higher altitudes. So if you are flying at 55 kts directly into a 55 kt wind, your relative groundspeed would be zero. From the ground, the aircraft would appear to be not moving. Anyone who holds a private license or higher knows this is a fact. It is taught to every student pilot.

If you mean relative to the ground, yes it's certainly possible, depending on the aircraft and the windspeed. Friend of mine has a vintage Auster and his favourite party piece is to cross the airfield going slowly backwards in a strong headwind. As long as the air is passing over the wings at sufficient speed to create sufficient lift, easy-peasy.

If you mean can you sustain flight without moving over the ground the answer would be yes. All it takes is a strong headwind and an airplane flying directly into it at the same air speed.

Well now I just have to go with the answers that said yes it is very possible.
Also it is well known to pilots, since they have to know what their air speed is compared to their ground speed, and how the wind direction and speed will affect them both. Also the temp. of the different air flows will make a big difference. I mean here, the up drafts and down drafts that warm and cold air cause (called thermals).
Flying is great and it is fun but you got to learn so much to do it lol. It is not just a climb in and go.

I have seen with my own eyes a glider remain effectively stationary (relative to the ground) in a good wind. Lift is provided by pressure difference caused by airflow over a wing (including helicopters) so most of the other answers are just plane wrong (pun intended!)

all the airplane desires to fly is air flowing over the wings speedy sufficient. If the air is shifting because of the fact I even have the engine turning and producing thrust and forcing me in the path of the air, I fly, if the wind is shifting speedy sufficient and the engine isn't even on, i will nonetheless fly. My wings have no theory if the air coming over them producing carry is coming over because of the fact of a heavy wind or if i'm pushing the throttle forward. Smaller airplanes that fly at slower speeds are enormously much continuously tied right down to anchor factors imbedded deep in the concrete of parking components with very reliable ropes subsequently. a easy 2 seater, say a Cessna a hundred and fifty desires the air to circulate over the wings at approximately 50 miles in line with hour to generate sufficient carry to make the airplane "decide on the flow". A 50 mile in line with hour wind isn't uncommon. A commercial airplane desires air circulate over the wing of greater like a hundred and sixty to one hundred eighty miles an hour to fly or for this reason decide on the flow. Granted you will no longer discover this is all however the main brutal of hurricanes on the floor, yet in the top environment in a jet bypass the place winds can attain speads of two hundred miles in line with hour somewhat, that's completely achieveable the airplane remains flying and keeping altitude whilst no longer making any forward progression over the floor (or perhaps shifting backwards). you will no longer somewhat see a commercial airliner doing this, because of the fact properly, airways gets a commission to get people places on time. whether somebody who occurred to very own say a 737 needed to play around and attempt it, air site visitors controllers might get enormously indignant on the airplane creeping alongside, gumming up their sectors and basically making their lives depressing. i've got not at all encountered a headwing stiff sufficient so as that i could desire to hover in a easy airplane, yet i've got had one stiff sufficient to purely make a floor velocity of 5 miles in line with hour.
