ok dude this is like the second time i get this kinda of question. I will tell you how it work ok? the propellers on an airplane wings works only by the pilots turning them on. The piliots switches a switch on top of his head know as the engine ignition. The plane propellers will spin as the plane taxies to the runway.
The propellers act as a thrusting force which drives the airplane forward. In addition to the wings and vertical and horizontal tail wings, this helps an airplane to become airborne and fly.
you press the start button and your on your way
Only if the airplane is in the water. Torpedos are water weapons and seldom, if ever, get airborne. Their propellers don't work in the air.
Some airplanes have had up to 8 propellers.
Yes, some airplanes have propellers.
Helicopters have rotors airplanes have propellers
The engines, driving propellers or jets, make the airplane move.
They propel the aircraft by propellers or jet thrust.
No both jets and gliders do not have propellers
No, that is not possible except with rotors. (which I would include among propellers)
From their speed and wings combined. Overall they work like an airplane, except they get their speed from clapping their wings.
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.
