Aircraft propulsion systems

This report treats the aircraft propulsion systems. It`s structured into

four parts.
1st part: the turbojet engine
2nd part: the turbofan engine
3rd part: the turboprop engine
4th part: the ramjet engine

1st part: the turbojet engine:

The first turbojet engine was flown in Germany in 1939. It was tested on a

Heinkel He 178.
The engines which now are in use, are in a great deal more complicated and

are producing more thrust.
A cutaway view of a three shaft turbojet engine with afterburner, as used

at the supersonic fighter PANAVIA TORNADO, the Turbo Union RB 199-34R is

shown here.
The technical data from the RB199-34R are:

max. thrust with afterburner........71 kN
pressure-difference.....................23%
rotation speed..............................12´000/14´000
rpm
weight.............................................1000 kg

70 kg air per second are going the following way through the
engine:
At first the air is sucked through low-press-compressor. In this case it

has three stages. (A stage consists of a single row of rotating and fixed

compressor blades.) The LP-compressor is working with low rotation
speed.
Then the air is passing the three stage MP-compressor. After it the air has

only 87% of its intake volume.
While the air is going through the HP-compressor with six stages, it`s

compressed to 77% of its original volume.
