How are airplanes powered?

Question

How are airplanes powered?

Answer 1

TNT

Answer 2

This is a very broad statement. Jets are powered by a jet engine (see this http://en.wikipedia.org/wiki/Jet_engine)... and propeller planes are powered by a propeller.

Answer 3

Whether it's with a turbine or an internal combustion engine essentially what moves the aircraft is pushing air backwards so much that it actually moves the airplane forwards.

A turbine, or jet, can do this job much faster and with much more force. So you can make the aircraft go faster as a result.

Answer 4

By gas.

Plain and simple.

Jet fuel.

High octane regular ol' Gasoline.

Answer 5

Modern jet airplanes use 4 basic types of air-breathing jet engines: turbojet, turboprop, turbofan, and ramjet.  Each have tradeoffs as to power vs. fuel economy, and which one is used depends on the aircraft being designed.

The large passenger jets are powered by turbofan jets, which have better thrust but better fuel economy (for cheaper plane tickets).  Turbojets, the first type invented, are used in fighter planes due to high thrust (and speed) where fuel efficiency is not the most important aspect.  

The engines suck in massive amounts of air.   The more air, more powerful fire, less air means less fire (just like the firemen teach).  The air is compressed and then mixed with fuel that is ignited and then the out air passes though a turbine before being thrust out the back.  

Of course, its the wings that provide lift to get the plane off the ground, otherwise you would just have a jet car.

Answer 6

1) gliders=unpowered

2) piston engine propeller

3) turboprop (turbine engine turning propeller)

4) jet

Answer 7

If you mean how do they stay up(?!!), commercial airlines use acceleration at takeoff plus the engines to generate a flow of air under the wings. This produces an upward force great enough to keep the plane in the air. Flaps are used to either regulate this force or brake. Turning the flaps on the wings down produces a greter angle that increases the vertical force of the flow of air and thus increases the planes upward acceleration. Turning the flaps upwards causes the flow of air to act as a horizontal brake. The plane meets more resistance and thus is slowed

Answer 8

By a prop blade or a jet turbine
