Question:
the type of compressor or compressors for which the engine is designed.
Answer:
What is the greatest factor influencing the construction features of any gas turbine engine?
Question:
turbofan, turboprop, turboshaft, and turbojet.
Answer:
What are the four types of gas turbine engines used to propel and power aircraft?
Question:
noise and fuel consumption
Answer:
What do turbojet engines have problems with?
Question:
.8 Mach
Answer:
What is the typical speed that airliners fly?
Question:
turbofan engine
,Answer:
Almost all airliner-type aircraft use what type of engine?
Question:
about 80%
Answer:
How much percent of thrust do turbofan engines produce?
Question:
two-shaft also known as two spool engines
Answer:
How many shaft engines are turbofan engines?
Question:
High-pressure spool
Answer:
This spool makes up the core of the engine and is where the combustion section is located.
Question:
gas generator
Answer:
What is the high-pressure spool also referred to as?
Question:
Low-pressure spool
Answer:
, This generally contains the fan(s) and the turbine stages it takes to drive them.
Question:
bypass ratio
Answer:
The amount of air that is bypassed around the core of the engine determines this.
Question:
bypass ratio
Answer:
The amount of air flow in lb/sec from the fan bypass to the core flow of the engine is this.
Question:
lb/sec flow fan divided by lb/sec flowcore
Answer:
How do you calculate bypass ratio?
Question:
augmenters or afterburners
Answer:
For low bypass turbofan engines which use speed ranges above.8 Mach (such as military aircraft)
what is used to increase thrust?
Question:
by adding more fuel nozzles and a flame holder in the exhaust system
Answer:
How can we gain large amounts of thrust for short amounts of time?
