How long does it take to start a jet engine?

At a certain rotation speed of the engine compressor, the fuel valves open. The compressed kerosene-air mixture then ignites, after which the motor then operates independently. This operation is carried out for each engine, generally one after the other, and takes about one minute.

How efficient is jet engine?

The combustion efficiency of most aircraft gas turbine engines at sea level takeoff conditions is almost 100%. It decreases nonlinearly to 98% at altitude cruise conditions. … For any type of combustion chamber there is a rich and weak limit to the air-fuel ratio, beyond which the flame is extinguished.
