  Turbojet Engines
The first and simplest type of gas turbine is the turbojet.
For a jet engine, the exit mass flow is nearly equal to the free stream mass flow, since very little fuel is added to the stream.
The thrust equation for a turbojet is given on a separate slide.

  turbojet - Definitions from Dictionary.com
An aircraft in which a turbojet is used.
In a turbojet, greater efficiency and control is obtained by having the escaping exhaust drive a turbine before leaving the engine and by having that turbine drive intake fans that compress the incoming air before it is ignited.
The turbojet engine is used in high-performance fighter jets, but if speeds are kept down to a few hundred miles per hour, the aerodynamics of the propeller or fan offers certain advantages; for this reason, the turbofan was developed.

 ch10-3
The turbojet shown at the top of the figure consists of high- and low-pressure compressors, combustor, and high- and low-pressure turbines.
To augment the wheel brakes and aerodynamic drag in decelerating the aircraft, the engines of turbojet- and turbofan-powered transport aircraft are equipped with some form of diverter that, when activated, reverses the thrust and thus provides a powerful stopping force.
Many of the early noise suppressors employed on turbojet propulsion systems were based on the concept of effectively breaking the large exhaust Jet into a number of small jets so that the relative amount of noise at the lower frequencies is reduced.

Turbojets are the simplest and oldest kind of general purpose jet engines.
Early turbojet compressors had overall pressure ratios as low as 5:1 (as do a lot of simple auxiliary power units and small propulsion turbojets today).
In a turbojet almost two thirds of all the power generated by burning fuel is used by the compressor to compress the air for the engine.

 A tiny turbojet for model aircraft
Since the introduction of the first operational turbojet engine some 50 years ago by Frank Whittle and his team in Great Britain, the engines have become bigger and bigger to meet the demands of high fuel efficiency and specific thrust.
The turbojet engine has been divided into several modules that are combined by means of bolts, press-fit connections, and special clamps.
After rotor runout, the temperature within the bearing module increases slightly from 176°F to 189°F because of radiation effects from the turbine and combustor, as the bearing module is no longer cooled by the relatively cold air passing it during normal engine operation.

 Propulsion
The typical turbojet engine has all 5 of the components described in the previous section: an inlet, a compressor, a combustor, a turbine, and a nozzle.
The turbojet is the engine of choice for most high-speed aircraft, in spite of the cost of the higher fuel consumption.
If a turbofan engine and a turbojet engine are compared at the same thrust and flight speed, the turbofan, like the turboprop, will have a substantially lower fuel consumption.

In addition, the thermojet was far larger and heavier than a turbojet, and the piston engine needed to power the compressors was quite complicated.
For these reasons, the turbojet and the related turbofan have become the dominant forms of aviation propulsion while the thermojet faded into obscurity.
One of the few applications where the thermojet found a home was in later versions of the Japanese Ohka kamikaze aircraft, but this engine was deemed too underpowered and replaced by a turbojet.

 Propulsion
There are four basic types of air-breathing engines (turbines): the turbojet, the turboprop, the turbofan, and the ramjet.
The turbojet engine is the most popular engine for most high-speed aircraft, in spite of the higher fuel consumption.
Soon after the first turbojets were in the air the turboprop engine was developed.

 Aerospaceweb.org | Ask Us - Jet Engine Types
The term "jet engine" is often used as a generic name for a variety of engines, including the turbojet, turbofan, turboprop, and ramjet.
A further variation on the turbojet is the turbofan.
Air is drawn in through an inlet, compressed by low- and high-pressure compressor blades, mixed with fuel and burned in a combustion chamber, passed through turbine blades, and exhausted through a nozzle.

The Pratt & Whitney J58 engine was a nine-stage, axial-flow, bypass turbojet originally developed in the late 1950s to meet U.S. Navy requirements.
It was the first jet engine designed to operate for extended periods using its afterburner.
The fuel itself was rendered inert by the infusion of nitrogen and then circulated around various components within the airframe as a coolant before being routed into the J58 engines for burning.

 Reviews | Tagan TurboJet 1100W - APH Networks
Personally, keeping the floppy power connector separate on the Tagan Turbojet 1100W is not a bad idea due lack of usage in floppy disk drives nowadays.
At the back of Tagan's TurboJet 1100W power supply is another 80mm fan; corresponding to the one in front to create optimal airflow from back of the unit to the front.
It's not too loud, but it seems to me that the Tagan TurboJet 1100W does produces its own share of noise -- and according to my observations, the relatively higher frequency noise is clearly audible even from a certain distance.
