Question 2

What are the two types of reciprocating engine exhaust systems?

Answer 2

Short stack system, and collector system

Question 3

What are the possible hazards of exhaust system failure?

Answer 3

Carbon monoxide poisoning of the crew and passenger ,partial or complete loss of power and aircraft fire

Question 4

What type of exhaust system is generally used on low powered non-supercharge engine

Answer 4

The short stack system

Question 5

What type of exhaust system is used on turbocharged engine?

Answer 5

Exhaust collector system

Question 6

What type of exhaust system creates a higher exhaust back pressure

Answer 6

The collector system

Question 7

What is the purpose of reciprocating engine exhaust system?

Answer 7

To remove heat and noxious gas from the engine nacelle

Question 8

What removes noxious gas and heat?

Answer 8

Exhaust system

Question 9

What are the three components of an exhaust argument system

Answer 9

Bellmouth ,sleeve and vanes

Question 10

What happens when lead, zinc, galvanized marks are made on an exhaust system

Answer 10

The mark is absorbed by the metal when heated which causes a change in the molecular structure that weakens the metal

Question 11

How are ceramic coated exhaust stack cleaned?

Answer 11

Degreasing method only

Question 12

What is the usual cause of muffler and heat exchange failures

Answer 12

By concentrated areas of thermal stress of vibration stress

Question 13

What is the most common form of damage in exhaust system?

Answer 13

Cracks due to repeated expansion and contraction

Question 14

What should be the position of the waste gate when starting an engine

Answer 14

Fully open

Question 15

Where are the exhaust manifold and stack failures most likely to occur

Answer 15

At the weld, flanges , or clamp points

Question 16

What is the common cause of Waste gate unit malfunctioning in a turbocharge system?

Answer 16

Carbon build up

Question 17

What are the factors affected if the areas of the exhaust nozzle of a turbine engine is changed

Answer 17

Engine performance and EGT

Question 18

Why are thrust reverser not normally use doing ground operation?

Answer 18

Danger of blowing foreign object up to the intake stream is too great

Question 19

What are the probes in a turbo exhaust pipe used for?

Answer 19

To measure EGT and pressure

Question 20

Why do you disassemble and inspect the collector type exhaust?

Answer 20

 Exhaust system, failure can cause carbon monoxide poisoning of crew and passenger

Question 21

What is the purpose of the waste gate on a turbocharge exhaust?

Answer 21

the valve that controls the amount of exhaust gases forced through the turbo charger turbine

Question 22

Name two types of thrust reverser?

Answer 22

Mechanical blockage in aerodynamic blockage type

Question 23

Can a thrust reverser deliver100% of engine power

Answer 23

No

Question 24

what material is used to make exhaust system muffler shroud?

Answer 24

Stainless steel

Question 25

What drawback in using collector type exhaust systems is more than offset when used on turbo charged engine

Answer 25

Loss of horsepower due to exhaust system back pressure

Question 26

Why are turbocharged exhaust system leaking very damaging at the high altitude

Answer 26

Pressure differential will cause leak to escape with torch like intensity

Question 27

What are the components of a typical turbine exhaust nozzle

Answer 27

tail cone, exhaust duct, and support Struts
