jet propulsion

jet propulsion
A form of propulsion where a mass of air is accelerated through a large change in velocity, and the body is propelled forward as a result of the action-reaction phenomenon, or Newton’s third law of motion. The propulsion unit obtains its oxygen from the air for imparting a higher velocity to the incoming gases by combusting fuel. The thrust is obtained by expelling a mass air flow at a higher velocity than its incoming velocity.
In the above case, velocity of exhaust gases (Vje) is much greater than those of gases at the inlet (Va). The accelerated gases push the aircraft forward by reaction in accordance with Newton’s third law of motion.
