2. DEFINE
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
All jet engines, which are also called gas
turbines, work on the same principle.
The engine sucks air in at the front with a fan. ...
The burning gases expand and blast out through the
nozzle, at the back of the engine. As the jets of gas
shoot backward, the engine and the aircraft are
thrust forward.

3. Fuel is mixed with air and electric sparks light the air
,causing it to combust.

4. It is also known as a burner, combustion
chamber or flame holder. In a gas turbine engine,
the combustor or combustion chamber is fed high
pressure air by the compression system. ... After
heating, air passes from the combustor through the
nozzle guide vanes to the turbine.
(i) Increase in air also increase the pressure.
Inverters convert an aircraft's direct current (DC),
typically from the main bus, into an alternating current
(AC), usable for other electronic needs. The converted AC

5. is usually a 24-volt system for aircraft that combines the
use of appropriate transformers, switching and control
circuits
he compressor is made with many blades attached
to a shaft. The blades spin at high speed and
compress or squeeze the air. The compressed air is
then sprayed with fuel and an electric spark lights

through the nozzle, at the back of the engine.

(II) Combustion chamber
(III) Turbine
(IV) Exhaust nozzle
(V) After burners

7. The high energy air flow coming out of the combustion
chamber goes into the turbine, causing the turbine
blades to rotate .the turbines are linked by a shaft to turn
the blades in them ,compressor and to spin the intake
fan at the fort.

9. A turboprop engine is a turbine engine that
drives an aircraft propeller. In its simplest form a
turboprop consists of an intake, compressor,
combustor, turbine, and a propelling nozzle. Air is
drawn into the intake and compressed by the
compressor.

10. A turbojet engine is a jet engine which
produces all of its thrust by ejecting a high
energy gas stream from the engine exhaust
nozzle. ... The component parts of
a turbojet engine are the inlet, the gas
turbine engine, consisting of a compressor,
a combustion chamber and a turbine, and
the exhaust nozzle
rA ramjet, sometimes referred to as a flying stovepipe or
an athodyd, is a form of airbreathing jet engine that

11. uses the engine's forward motion to compress incoming
air without an axial compressor or a centrifugal
compressor.
(*) it has no moving parts.
Jet engines moves the airplane forward with a great
force that is produced by a tremendous thirst and causes
the plane to fly very fast.
(i) Air intake
(ii) Compressors
(iii) Combustors
(iv) Turbines
(v) Nozzles
(vi) fuel systems

12. (vii) cooling system
The cooling air then passes through complex
passages within the turbine blades. After removing
heat from the blade material, the air (now fairly hot)
is vented, via cooling holes, into the main gas
stream. Cooling air for the turbine vanes
undergoes a similar process.

13. (I) Jet engine is nothing but a gas turbine.
(II) It works under the principles of newton third
law.
(III) About 75% of fuel is used in produsig the thirst.
(IV) Gas turbines operate like a gas balloon.
(V) Ramjet has no moving part.
(VI) Compression rstio depends on the forward
speed.
(VII) It has no static thirst.

14. Jet engine designs are frequently modified for non-
aircraft applications, as industrial gas turbines or
marine power plants. These are used in electrical
power generation, for powering water, natural gas,
or oil pumps, and providing propulsion for ships and
locomotives.
