Question 1

What are the two methods used to exhaust the cold bypass air and hot exhaust gases?

Answer 1

The standard method and the integrated exhaust nozzle method.

Figure 18.5 shows two methods used to exhaust the cold bypass air and the hot exhaust gases.

Question 2

What does the top illustration in Figure 18.5 show?

Answer 2

The standard method where the hot and cold nozzles are co-axial and the two streams mix externally.

Figure 18.5 shows two methods used to exhaust the cold bypass air and the hot exhaust gases.

Question 3

How can greater efficiency be obtained in exhausting the cold bypass air and hot exhaust gases?

Answer 3

By fitting an integrated exhaust nozzle where the two gas flows are partially mixed before ejection to atmosphere.

Greater efficiency can however be obtained by fitting an integrated exhaust nozzle.

Question 4

What is the external mix of gas streams in the exhaust system?

Answer 4

The standard method where the hot and cold nozzles are co-axial and the two streams mix externally.

Figure 18.5 shows two methods used to exhaust the cold bypass air and the hot exhaust gases.

Question 5

What is the partial internal mixing of gas streams in the exhaust system?

Answer 5

Within an integrated exhaust nozzle, the two gas flows are partially mixed before ejection to atmosphere.

Within this unit the two gas flows are partially mixed before ejection to atmosphere.
