Answer 1

Intake= air inlet section, comp= compressor section, ignition and power= combustion, and turbine sections, exhaust= exhaust section

Question 2

What type of turbo jet engine is commonly used in commercial aviation due to lower noise and better fuel consumption

Answer 2

High bypass turbo fan engines

Question 3

What adjustments and rigging are accomplished on a turbine engine

Answer 3

The primary rigging on a turbine engine involves the adjustment of power control, levers, and cables, followed by adjustment of the fuel control unit to trim the engine for the correct idle speed speeds to obtain maximum thrust 

Question 4

What are the two types of turbine compressors?

Answer 4

Centrifugal flow and axial flow

Question 5

What is meant by trimming a turbine engine?

Answer 5

Adjusting the fuel control so the engine develops the correct idle and trim speed RPM

Question 6

What type of equipment should be used to determine that a turbine engine is performing up to the standards specified by the engine manufacturer

Answer 6

A jetcal analyzer/trimmer has all of the instrumentations and cables to determine the EGT, EPR, and other parameter specified by the engine manufacturer
