What is a turbojet?
A turbojet is one of the very first types of jet engine. Turbojets are different than turbofans- jet engines that most modern aircraft use.
Are turbo-shaft engines louder than turbojet?
No, a jet engine is louder.
What type of engine does a B52 have?
The B-52H has eight Pratt & Whitney TF33-P-3 turbofan engines, each providing more than 17,000lb of thrust.
Which engine used in airplane?
Ordinary jet engines are used on aircrafts. But some planes require turbojet engines. These planes fly at more than the speed of sound. There are other type of airplane types too.
How does a turbojet engine work?
Axial Turbojet; Air enters the engine and goes through a compressor, increasing the air's pressure and temperature. The air then enters the combustor where it is mixed with fuel and ignited. Next, the hot gas expands and spins the turbine which powers the compressor. Finally, the exhaust passes through a convergent nozzle into the atmosphere, creating a high velocity jet which pushes the aircraft. Centrifugal Turbojet; Nearly the same as an axial-flow turbojet, the centrifugal-flow turbojet compresses the air by diverting it from the axis of flow. While this type of jet is simpler, lighter and cheaper than axial-flow, it is less efficient and can not handle as high a volume of air. Often a combination of axial and centrifugal compressors are used in modern jets.
What is the speed of fan in a turbofan engine?
Most turbofan engines have parts running at more than one speed. The inner most compressor stages and the first turbine stages usually turn faster than the outer stages. The more popular engines seen on airliners use three stages, and three different speeds at any given time. Watch a modern airliner engine during engine start and you can hear the inner stages begin to spin up before you will see the outer fan stage begin to rotate. It depends on the engine, but the largest fan stage which is seen in the intake will be less than 10k rpm, often less than 5k.
What are the features of the Boeing 757?
The Boeing 757 has redesigned wings, under-wing engines and is made out of lighter materials than it's predecessors, making it a more economical model. It has a two-crew member glass cockpit, turbofan engines, a supercritical wing design (which is used to reduce aerodynamic drag) and a conventional tail.
Why turboprop engine fly at low altitude than turbofan engine?
A turboprop aircraft, such as a Cessna, cannot fly as fast as a turbofan aircraft, such as a Boeing. Because of this, lift cannot be maintained at high altitudes. As you go higher, you can go faster because there's less air to slow you down. But if you don't go fast enough, then the plane will stall and keep falling until it reaches an altitude at which lift can be maintained at its current speed.
How fast does the turbofan go?
A turbofan engine is the most modern variation of the basic gas turbine engine. As with other gas turbines, there is a core engine, whose parts and operation are discussed on a separate page. In the turbofan engine, the core engine is surrounded by a fan in the front and an additional turbine at the rear. The fan and fan turbine are composed of many blades, like the core compressor and core turbine, and are connected to an additional shaft. All of this additional turbomachinery is colored green on the schematic. As with the core compressor and turbine, some of the fan blades turn with the shaft and some blades remain stationary. The fan shaft passes through the core shaft for mechanical reasons. This type of arrangement is called a two spool engine (one "spool" for the fan, one "spool" for the core.) Some advanced engines have additional spools for even higher efficiency.How does a turbofan engine work? The incoming air is captured by the engine inlet. Some of the incoming air passes through the fan and continues on into the core compressor and then the burner, where it is mixed with fuel and combustion occurs. The hot exhaust passes through the core and fan turbines and then out the nozzle, as in a basic turbojet. The rest of the incoming air passes through the fan and bypasses, or goes around the engine, just like the air through a propeller. The air that goes through the fan has a velocity that is slightly increased from free stream. So a turbofan gets some of its thrust from the core and some of its thrust from the fan. The ratio of the air that goes around the engine to the air that goes through the core is called the bypass ratio.Because the fuel flow rate for the core is changed only a small amount by the addition of the fan, a turbofan generates more thrust for nearly the same amount of fuel used by the core. This means that a turbofan is very fuel efficient. In fact, high bypass ratio turbofans are nearly as fuel efficient as turboprops. Because the fan is enclosed by the inlet and is composed of many blades, it can operate efficiently at higher speeds than a simple propeller. That is why turbofans are found on high speed transports and propellers are used on low speed transports. Low bypass ratio turbofans are still more fuel efficient than basic turbojets. Many modern fighter planes actually use low bypass ratio turbofans equipped with afterburners. They can then cruise efficiently but still have high thrust when dogfighting. Even though the fighter plane can fly much faster than the speed of sound, the air going into the engine must travel less than the speed of sound for high efficiency. Therefore, the airplane inlet slows the air down from supersonic speeds.
What is the principle of turbojet?
A turbo jet is a jet engine that is used on planes that go faster than the speed of sound (768 mph). A turbojet starts by having compressor fans which compress the air that enters the engine, then that compressed air gets mixed with jet fuel in the combustion chamber which burns, then that burned air goes out of the combustion chamber and turns the turbines which takes some of the energy away from the exhaust. the turbines are attached to the compressor fans, so when the turbines spin, so do the compressor fans.

Is it correct to say you have more money than I or you have more money than me?
You have more money than I have --- therefore, it is "You have more than I."
Is there a car faster than the veyron?
The Bugatii Veyron is the fastest production car. (Well the Veyron SS is faster but that's just the newer model) The current land speed record is held by the ThrustSSC which uses twin turbofan engines and has reached a speed of over 1,200 km/h (~750 mph I think)
