A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. While this broad definition can include rocket, water jet, and hybrid propulsion, the term jet engine typically refers to an airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet. In general, jet engines are internal combustion engines. Current Turbofan Jet engines have a self-contained gas generator section, that creates the hot combustion gases which are used to turn a turbine, which is connected by a rotating shaft t.

A jet plane would have a turbine engine and the whole principle of the turbine engine include a combustion chamber which mean that jet fuel is used in order to create combustion.  In a typical scenario of this type, the pilot might have heard a ‘thud’ sound in the cockpit as the missing parts collided, but the first good evidence would have been a high N1 (fan shaft) vibration on the cockpit display, accompanied by the appropriate level of alert (advisory, caution or warning) for the level of vibration created by the loss of.

It is the product of jet plane types generator efficiency of the process that converts fuel flow p,ane to shaft power herein called motor thermodynamic efficiency and propulsive efficiency the conversion.

The basic idea of the turbojet engine is simple. Air taken in from an opening in the front of the engine is compressed to 3 to 12 times its original pressure in the compressor. Fuel is added to the air and burned in a combustion chamber to raise the temperature of the fluid mixture to about 1, F to 1, F.

The resulting hot air is passed through a turbine, which drives the compressor. If the turbine and compressor are efficient, the pressure at the turbine discharge will be near twice the atmospheric pressure , and this excess pressure is sent to the nozzle to produce a high-velocity stream of gas which produces a thrust.

Substantial increases in thrust can be obtained by employing an afterburner. It is a second combustion chamber positioned after the turbine and before the nozzle. The afterburner increases the temperature of the gas ahead of the nozzle.

The result of this increase in temperature is an increase of about 40 percent in thrust at takeoff and a much larger percentage at high speeds once the plane is in the air. The turbojet engine is a reaction engine. In a reaction engine, expanding gasses push hard against the front of the engine. The turbojet sucks in air and compresses or squeezes it. The gasses flow through the turbine and make it spin.

These gasses bounce back and shoot out of the rear of the exhaust, pushing the plane forward. A turboprop engine is a jet engine attached to a propeller. The turbine at the back is turned by the hot gasses, and this turns a shaft that drives the propeller. Some small airliners and transport aircraft are powered by turboprops. Like the turbojet, the turboprop engine consists of a compressor, combustion chamber, and turbine, the air and gas pressure is used to run the turbine, which then creates power to drive the compressor.

Compared with a turbojet engine, the turboprop has better propulsion efficiency at flight speeds below about miles per hour. Modern aircraft generate power in the main engines or an additional fuel-burning turbine Do Jet2 Planes Have Entertainment engine called an auxiliary power unit , which is often mounted in the rear of the fuselage or in the main-wheel well. The RAT generates power from the airstream due to the speed of the aircraft.

If aircraft speeds are low, the RAT will produce less power. In normal conditions the RAT is retracted into the fuselage or wing , and is deployed manually or automatically following complete loss of power. In the time between power loss and RAT deployment, batteries are used. RATs are common in military aircraft which must be capable of surviving sudden and complete loss of power.

This allows their installation on a standard hardpoint , without requiring a pod-specific power supply. Also, some free-fall nuclear weapons, such as the British Yellow Sun and Red Beard , used RATs to power radar altimeters and firing circuits; these were a more reliable alternative to batteries.

A ram air turbine was chosen for the VC10 because of its use of ' packaged ' hydraulically-powered flying controls, rather than an overall valve-ram system, with centralised hydraulic power and a hydraulic emergency reserve system. A fully powered flying control system such as that of the VC10, rare on civilian aircraft up to that point, would require an excessively large hydraulic power reserve, with its own risks of failure.

The individual package units of the VC10 were each powered electrically and so emergency redundancy for the VC10 relied instead on quadruple generators and a backup RAT. A typical large RAT on a commercial aircraft can be capable of producing 5 to 70 kW , depending on the generator.

Smaller, low airspeed models may generate as little as watts. RATs have also been used to power centrifugal pumps to pressurize the spray systems on aircraft that are used as crop dusters to deliver liquid agents to cropland. Pulse jet engines are uncommon aircraft powerplants. In this pulse jet three air nozzles in the front section were connected to an external high-pressure air source, butane from an external supply was used for starting, ignition was accomplished by a spark plug located behind the shutter system, electricity to the plug being supplied from a portable starting unit.

Once the engine started and the temperature rose to the minimum operating level, the external air hose and connectors were removed, and the resonant design of the tailpipe kept the pulse jet firing. Each cycle or pulse of the engine began with the shutters open; fuel was injected behind them and ignited, and the resulting expansion of gases forced the shutters closed.

As the pressure in the engine dropped following combustion, the shutters reopened and the cycle was repeated, roughly 40 to 45 times per second. The electrical ignition system was used only to start the engine; heating of the tailpipe skin maintained combustion.
