For thrust.
Engines are used to overcome the drag of the airplane.
Jet fuel is injected into high pressure air in jet engines.
yes they are, they are the engines you see on a 747 or even a small Private jet
rocket engines,compared to jet engines
A rocket engine, or simply "rocket," is a jet engine[1] that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.Rocket engines as a group, have the highest exhaust velocities, are by far the lightest, and are the most energy efficient (at least at very high speed) of all types of jet engines. However, for the thrust they give, due to the high exhaust velocity and relatively low specific energy of rocket propellant, they consume propellant very rapidly.
A pulse jet engine is one of the most simple and efficient propulsion devices ever designed. There are three types of pulse jet engines: The valved pulse jet, the valveless pulse jet, and the upright or "Jam jar jet". For complete details on pulse jet engines, go to wikipedia.org and search "Pulse Jet Engine".
Jet powered aircraft have a number of advantages over conventional internal combustion propeller driven aircraft. To start with, jet engines can operate in a much wider range of conditions. Propellers lose their effectiveness at high altitudes and at high speeds while jet engines are capable of operating at much higher altitudes and a much much higher speeds with little or no loss of power. Jet engines have fewer moving parts than internal combustion engines which makes them easier and simpler to design, build, maintain and repair. Jet engines run on fuel that is very similar to diesel fuel, and is much safer to handle and store than gasoline. Jet engines can produce much more thrust power for their weight than conventional reciprocating engines do.
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
Jet streams
A jet propelled engine, commonly known as a jet engine, is a type of internal combustion engine that generates thrust by expelling jet streams of gas at high speeds. It works on the principle of Newton's third law of motion, where the action of expelling gas out the back produces an equal and opposite reaction that propels the aircraft forward. Jet engines are widely used in commercial and military aircraft due to their efficiency at high speeds and altitudes. There are several types of jet engines, including turbojets, turbofans, and turboprops, each designed for specific applications.
The jet engines used jet fuel, not gasoline as the 6 main engines did.
Reasons of efficiency. not the least of which is that the pressure generated in the combustion chamber has to fight less "back pressure" (think of it as pressure resistance) at high altitude because the air-pressure is less.
Yes. JP5 is primarily used in turbo fan engines, but they are blended for high performance and fuel economy.
Most planes use a type of aviation fuel known as jet fuel. Jet fuel is a specialized type of fuel designed for use in jet engines, which power most commercial airplanes. It is a type of kerosene that is refined for its high energy content and stability at high altitudes.
Jet fuel is injected into high pressure air in jet engines.
Jet engines primarily use aviation fuels, with Jet A and Jet A-1 being the most common types. These fuels are kerosene-based and designed to perform well at high altitudes and in cold temperatures. Additionally, military jets may use JP-8 or other specialized fuels, while some newer engines are being developed to utilize sustainable aviation fuels (SAFs) for reduced environmental impact.
