Combustion Chamber is part of the Hot Section with Exhaust and TurbinesFAQ: Hot spots on tail cone indicate that the combustion chamber of a jet engine is not properly working

Major Design Consideration

Problem: How to have a continuous ignition

flame burning despite the fast flowing air around it?Solution:

Create a purposeful turbulence around the flame.

Certain materials may be used to mark

combustion and turbine components during disassembly and assembly

layout dye, chalk, and some

commercial felt-tip markers are considered ACCEPTABLE for use in marking parts that are directly exposed to an engine's gas path such

as turbine blades and disks, turbine vanes, and combustion chamber liners

• In which type of turbine engine combustion chamber is the case and liner removed and installed as one unit during routine maintenance? CAN

• The air passing through the combustion chamber of a turbine engine is used to support combustion and to cool the engine.
