CLASIFICATION OF AEROENGINES

Aircraft power plants (engines) are internal combustion engines and are

of two types:

or intermittent combustion enginespiston engines: eType on

or continuous combustion enginesair breathing engines: Type two

Type two can be subdivided into engines:

:which include gas generator Without -

* Athodyd (Aero thermodynamic ducts) which includes:

The Ram jets, and

The Pulse jets.

* Rockets which could be:

Solid fuel, or

Liquid fuel.

: which includesWith gas generator -

* Turbojet engines that can be of:

Single spool, or

Double spool.

* Bypass engines that can have:

Front fan, or

After fan.

* Turbo shaft engines that can be: Helicopter engine, or Turbo propeller engine.

Definitions

This includes the evaluation of the : Engine Performance: 2.3.2

following parameters.

Propulsive efficiency: is the ratio of thrust power (TU) to the rate of

production of propellant kinetic energy.

Thermal efficiency: is the ratio of rate of addition of kinetic energy to

the propellant to the total energy consumption.

Propeller efficiency: is the ratio of thrust power to the shaft power.

Overall efficiency: is the product of propulsive efficiency by the thermal

efficiency.

A/C range

Specific fuel consumption (SFC): is the ratio of mass of fuel consumed

to the thrust produced (TSFC). Or the ratio of mass of fuel consumed to

the shaft power (BSFC). Or the ratio of mass of fuel consumed to the

equivalent shaft power (EBSFC).
