The compressed air passes through a small turbine on the outside of the engine, causing it to spin. Attached to the turbine is a shaft which is joined by gears to the main engine shaft, and that begins spinning as well. "The blades connected to the engine shaft then start rotating faster and faster," explains Brand.
On most twin or multi-engine propeller driven aircraft, the propellers all turn in the same direction, usually clockwise when viewed from the rear of the aircraft. In a counter-rotating installation, the propellers on the right wing turn counter-clockwise while those on the left wing turn clockwise.
One type discussed in How turbine engines work includes a normal "jet" engine on an airplane. … The electric motor spins the main shaft until there is enough air blowing through the compressor and the combustion chamber to light the engine. Fuel starts flowing and an igniter similar to a spark plug ignites the fuel.
Answer: 1. Air is drawn into the compressor where it meets with fuel, most commonly natural gas. This results in combustion, and the high-temperature and high-pressure gas then spins rotating blades, which draw more pressurized air into the combustor and spin the generator.

Engine, or crankshaft rotation, is the direction the engine spins: either clockwise or counterclockwise. Most vehicles have the standard rotation, counterclockwise.
Small planes (like the little Cessna in How Airplanes Work) have locks on the doors and ignition keys inside to start the engine. … Commercial jets, on the other hand, have no locks on the doors and no ignition key of any sort. You can hop in, flip a couple of switches and start one up!
The isolation valve in Open or Auto ensures that the Auxiliary Power Unit (APU) bleed air reaches the engine number 2 starter. Engine number 2 start Exhaust Gas Temperatures (EGT) are generally higher. Engine number 2 is started first because it's on the opposite side of the air bridge.
Jet engine exhaust contains carbon dioxide, oxides of sulfur and nitrogen, unburned fuel, soot and metal particles, as well as water vapor.
temperatures are also above the melting point of the metal turbine blades which make up the engine interior. These blades are forced to spin by the expanding hot exhaust gases travelling through the engine. … Clever materials science and engineering keeps these blades from melting.
