plane question here!!!!!!!please answer?

Question

where do planes get the electricity or energy to run the planes engines. is this the answer?....... when a plane lands they put a thing in the airplanes and it pumps electicity into the airplane in order to keep the lights on and the engines running?

Answer 1

On the ground, the aircraft can use one of two types of power sources. The self sufficient method is by the APU or Auxilliary Power Unit. It is for all intents a small turbine engine, about the size of a car engine-- and it creates the power. On some planes- like the 747 it is in the tail. On others, like the 727, it is up under the fuselage/wing root. The other method is for the power to be plugged in.

Answer 2

Ok, this is how it works, in simple terms. On the ground with the airplane engines off there can be 2 sources of electrical power to a plane. one being the power cord u see plugged into the side. The other being from the APU(auxiliary power unit) that on the plane. The APU is generally in the tail of the airplane on most commercial jets. The APU is like the engines on the wings except that its much smaller and doesnt provide thrust. if u dont have ground power(the power cord plugged in) power is run off the APU. Now, the APU is also used to start the engines also, by providing pnuematic(air) power to start them up. Once the engines are running the engines can provide the electrical power to the plane. This is done via generators on the engine such as a CSD(Constant Speed Drive) or an IDG(Integrated Drive Generator). To make things simple just think of them like the alternators to ur car. Its a bit more complicated than that but this is a basic easy to understand version. Hope this helps

Different ways to power different planes and systems.

Some planes are electrically based. They used batteries, APU, or ground power (almost like plugging it into a wall outlet). The engines when running make a ton of power for just about everything on the plane (plus a bunch of excess). The engines are started with electric starter motors.

Other planes use some electricity and a lot of "bleed air" to power things like the air conditioners, starting the engines, etc. Think of a pinwheel. They use an APU to provide the bleed air when the engines aren't running (the APU is started with batteries/electric motor). Or can be started by a ground source of bleed air (a big air compressor basically).

Planes also use a ton of hydraulic power. The engines have hydraulic pumps which run everything from the control surfaces to the landing gear, etc.

So it depends a lot on what exact plane you talking about but there are a variety of ways to "power" a plane.

Answer 4

OK, there are a few sources of electricity on an aircraft.

First, battery power. This is to operate all the equipment needed to start the aircraft and certain important equipment in case of main power failure.
Ground power : When the aircraft is on the ground and power is needed to test or inspect the aircraft as well as for lighting. All components can be powered now.
Auxillary power unit (APU) : a small jet engine usually located in the tail of newer aircraft. Can supply enough power for most sytems. On a 747-400 there are two generators on the APU

Each engine will have one generator which supplies the aircraft during flight

Answer 5

The engines of the plane are like the alternator for a car, they produce electricity as they go around, keeping the lights and instruments all charged, there is also an onboard battery, which powers everything while the plane isnt' on, kinda like your key in the on position for your car. Airports also have a huge jumpstarter kinda thing to help charge up a plane as well if need be. I got to see it first hand while leaving Flint Mi last Xmas Eve.

Answer 6

The engines have generators to supply shipboard electrical power. Many larger airplanes also have an auxiliary power unit (usually a small gas turbine powered generator) to supply electricity when the main engines are not running.

Answer 8

Think of it like this, planes are like big cars. They run on fuel! Don't ask me the whole mechanics of it but the fuel is what creates the energy to run the engines and the lights and stuff.

Answer 9

Hi lee
all aircrafts has generators inside, they need lots of electricity to operate all equipment aboard during the flight
besides it, when on ground, they are attached to ground power units through cables to save aircraft's generators

Answer 10

partially by batteries, to run the power for the avionics and instruments, as for the lighting, i believe that it is powered by the engines...
