Compressor Inlet Ducts Flashcards
1
Q
What are engine inlet ducts designed to provide?
A
Relatively distortion free airflow in sufficient quantities
2
Q
What do inlet guide vanes (IGVs) do?
A
Straighten airflow and direct it to first compressor stages
3
Q
What consumes more airflow gas turbine engines or reciprocating engines?
A
Gas turbine engines consume a considerable amount more airflow than reciprocating engines
4

A
Using a mesh screen
5
Q
What does a speed increase nor,ally mean for thrust ?
A
A thrust decrease
6
Q
What must an inlet be able to do for high speeds?
A
Recover as much of the free airflow as possible
7
Q
