A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .

2018年5月21日 · One of the most common types of airplanes in use today is the jet, which has largely replaced traditional aircraft powered by propellers. Although propeller planes still see some flying action, jets dominate commercial and private air travel due to their greater speed, ability to fly at higher altitudes and mechanical reliability.

A jet airliner or jetliner is an airliner powered by jet engines (passenger jet aircraft). Airliners usually have two or four jet engines; three-engined designs were popular in the 1970s but are less common today.

2022年8月30日 · A jet uses a jet engine to propel itself, like the Airbus A380. An airplane is a heavier-than-air aircraft with fixed wings and an engine. In short, all jet aircraft are airplanes, but not all airplanes are jet aircraft. An example of an airplane that isn't a …

From the very invention of flight at the beginning of the 20th century, military aircraft and engines generally led the way, and commercial aviation followed. At first this was also the case in the jet age, which began with the invention of jet engines under military sponsorship in …

2023年9月14日 · In short, a jet can be a plane, but a plane can’t always be a jet. This is because a jet describes any plane that has a jet engine. A jet engine can either be a turbojet or turbofan engine, whereas a non-jet engine used in an aircraft is usually a turboprop.

A jet aircraft is an aircraft that is propelled by jet engines. Jet engines work by taking in air at the front of the engine, compressing it, mixing it with fuel, and igniting the mixture to create a high-velocity exhaust stream that propels the aircraft forward.

Reciprocating engines for aircraft had reached a practical limit with the 3,500-horsepower, 28-cylinder Pratt & Whitney R-4360 engine, while some modern jet engines, such as the General Electric GE90-115, can produce as much as 115,000 pounds of thrust.

Take a thorough look inside a modern jet passenger aircraft. Electronics, hydraulics, flight control surfaces, fuel system, water and waste, lighting, and mo...
