Difference Between Jet and Airplane
Is there a difference between a jet and airplane? The answer is, kind of.
All jets are airplanes, but not all airplanes are jets. Most commercial airplanes are jets. There are still propeller driven commercial airplanes in some of the more desolate and scarcely populated areas, but for regular air travel, jets are the aircraft of choice.
Before the invention of the jet engine, a standard combustion engine and propeller powered airplanes, but the jet engine opened new doors in the world of aviation. Jets generate thrust by expelling a fluid in the opposite direction of the desired motion. Once air enters the jet engine, it is pressurized and combined with fuel. Once combustion occurs, the resulting gas is released through the exhaust, and thrust is achieved.
This method of propulsion has numerous advantages over propeller driven aircraft. For one, jets are much faster than propeller-driven aircraft. They can even exceed the speed of sound. This is not possible with propeller driven aircraft. Jets also provide a more comfortable ride to their passengers. Because of the nature of their propulsion system, jets can fly higher than propeller aircraft and avoid turbulence. They can fly higher because they do not require dense air like the older propeller aircraft. The can compress thin air as easily as dense air. There greater power also allows the aircraft to be larger. The average jumbo jet could never achieve the necessary lift to get off the ground if it depended strictly on propellers.
Both jet and airplane aircraft are still in use today. Jets may be technically superior, but they are expensive to maintain. This has kept propeller craft in service. Airline companies often use propeller driven aircraft for shorter flights to smaller airports. While noisy and slow, these aircraft are cheaper. Propeller aircraft consume less fuel and are easier to maintain.
