CH10 - GAS TURBINE - COMPRESSORS

Question 1

Which of these statements about compressor stall are correct or incorrect?
I. A compressor stall is most likely to occur in a compressor designed for a high pressure ratio operating at low RPM.
II. A compressor stall is most likely to occur when the air flow stagnates in the rear stages of the compressor.

Answer 1

CORRECT CORRECT

Question 2

Several compressor stall can be observed amongst others by:

Answer 2

A rise in TGT and a change in vibration level

Question 3

EPR = Pto_total / Pci _total

Question 4

compReSsor’de Rotor sonra Statör gelir.

Answer 4

compReSsor R > S

Question 5

The blades in an axial flow compressor decrease in size from the LOW PRESSURE TO THE HIGH PRESSURE STAGES IN AN ATTEMPT TO SUSTAIN AXIAL VELOCITY

Answer 5

Kompressörde bıçakların boyutları git gide küçülüyor çünkü, havanın yanma odasına kadar belli bir hızda (basınç artacak) taşınabilmesi lazım.
