2
describe the purpose of three sections of a Gas Turbine Engine..?
3
Explain the working cycle of Gas Turbine engine and the realationship between pressure,and velocity and volume and temperature..?
الإجابةQ1
describe the basic principles of aircraft propulsion using simple equationsthe propulsion depends on the mass flow rate and the air velocity, where we can say
P= m (Vo - Vi), wherem= the mass flow rateVo= the velocity of exhoustVi= the velocity of inlet
Q2
describe the purpose of three sections of a Gas Turbine Engine
the compressor
It is used to compress the air, which increases the inlet air pressure through the compressor stages, it is known as a cold section
the Combustion chamber
Where the fuel-air mixture is burned and paeesd to the turbine
the turbine
It is used to preduce a high velocity exit
Q3
Explain the working cycle of Gas Turbine engine and the realationship between pressure,and velocity and volume and temperature
in compressor
P inlet less then P comp
V inlet higher than V comp
with P increase in the Compressor T increase / V decrease
in CC
P & V constant
T increase with increase in Volume
turbine
P & T decreaseV increase
