Engine Exhaust And Reverse Systems Flashcards
What are the two general types of exhaust systems in use on reciprocating engine?
Short stack, and a collector system
What are the two types of reciprocating engine exhaust systems?
Short stack system, and collector system
What are the possible hazards of exhaust system failure?
Carbon monoxide poisoning of the crew and passenger ,partial or complete loss of power and aircraft fire
What type of exhaust system is generally used on low powered non-supercharge engine
The short stack system
What type of exhaust system is used on turbocharged engine?
Exhaust collector system
What type of exhaust system creates a higher exhaust back pressure
The collector system
What is the purpose of reciprocating engine exhaust system?
To remove heat and noxious gas from the engine nacelle
What removes noxious gas and heat?
Exhaust system
What are the three components of an exhaust argument system
Bellmouth ,sleeve and vanes
What happens when lead, zinc, galvanized marks are made on an exhaust system
The mark is absorbed by the metal when heated which causes a change in the molecular structure that weakens the metal
How are ceramic coated exhaust stack cleaned?
Degreasing method only
What is the usual cause of muffler and heat exchange failures
By concentrated areas of thermal stress of vibration stress
What is the most common form of damage in exhaust system?
Cracks due to repeated expansion and contraction
What should be the position of the waste gate when starting an engine
Fully open
Where are the exhaust manifold and stack failures most likely to occur
At the weld, flanges , or clamp points
What is the common cause of Waste gate unit malfunctioning in a turbocharge system?
Carbon build up
What are the factors affected if the areas of the exhaust nozzle of a turbine engine is changed
Engine performance and EGT
Why are thrust reverser not normally use doing ground operation?
Danger of blowing foreign object up to the intake stream is too great
What are the probes in a turbo exhaust pipe used for?
To measure EGT and pressure
Why do you disassemble and inspect the collector type exhaust?
 Exhaust system, failure can cause carbon monoxide poisoning of crew and passenger
What is the purpose of the waste gate on a turbocharge exhaust?
the valve that controls the amount of exhaust gases forced through the turbo charger turbine
Name two types of thrust reverser?
Mechanical blockage in aerodynamic blockage type
Can a thrust reverser deliver100% of engine power
No
what material is used to make exhaust system muffler shroud?
Stainless steel
What drawback in using collector type exhaust systems is more than offset when used on turbo charged engine
Loss of horsepower due to exhaust system back pressure
Why are turbocharged exhaust system leaking very damaging at the high altitude
Pressure differential will cause leak to escape with torch like intensity
What are the components of a typical turbine exhaust nozzle
tail cone, exhaust duct, and support Struts
