Book 2 - Compressor Introduction

Question 1

what are the two types of compressor used in gas turbine engines?

Answer 1

• centrifugal vane

- axial flow

Question 2

the centrifugal compressor is usually more ______ than the axial flow types and also easier to develop and __________

Answer 2

the centrifugal compressor is usually more ROBUST than the axial flow types and also easier to develop and MANUFACTURE

Question 3

the axial flow compressor consumes far more ___ than the centrifugal compressor of the same _______ area and can also be designed for high pressure ______ more easily. since the air-flow in an important factor in determining the amount of thrust, this means that the axial compressor engine will also give more _____ for the same frontal area

Answer 3

the axial flow compressor consumes far more AIR than the centrifugal compressor of the same FRONTAL area and can also be designed for high pressure RATIOS more easily. since the air-flow in an important factor in determining the amount of thrust, this means that the axial compressor engine will also give more THRUST for the same frontal area

Question 4

with higher _______ ratios, there is a higher engine _________ and performance due to an improved specific ____ consumption and thrust

Answer 4

with higher PRESSURE ratios, there is a higher engine EFFICIENCY and performance due to an improved specific FUEL consumption and thrust
