Jet Aircraft vs. Propeller Aircraft While hybrid engines and electric cars have begun to change the way we travel, the airplane still remains the fastest and most efficient way of travelling long distances. The 1903 invention of the airplane has kept relatively the same principle. During its hundred plus years the idea has only experienced several major advancements. The most notable of these being the jet engine. Today the jet engine and the propellor engine remain both useful for flight The jet engine was one of the most powerful inventions of the 20th century. Its invention during the closing days of world war two changed travel and warfare completely.The jet engine compresses air in the front of engine …show more content…
Then the compressed air is combined with compressed fuel. The combustion of these components at a very high temperature causes the gases to expand rapidly causing a significant thrust to come from the engine. In turbojet engines, this thrust causes the entire force of the engine while in some it does not. . Turboprop engines are used have the drive shaft connected to a propeller or another system. This distinction allows these engines to be used in cars, ships and other vehicles that don’t necessarily fly. In turbofan engines the rotational force that is created by the hot section of the engine is applied to a fan in the front part of the engine that pushes air through an external cavity of the engine causing additional thrust, which makes it significantly more efficient and than the original turbojet. In extremely high velocity aircraft, such as fighter jets the experience a significant increase in drag as they approach the speed of sound. To overcome this, a secondary area for injecting fuel
