Jeppesen Oral- Chapter 10 (Cooling Systems)

Answer 1

Shortens life of engine, changes combustion behavior and impairs lubrication

Answer 2

Provide larger cooling surface area for removing heat from cylinder

Answer 3

Cowling serves to streamline the engine, and together with the baffles and cowl air seals, directs airflow over cylinders to promote cooling

Answer 4

Control the amount of airflow through cowling. Operated mechanically, electrically or hydraulically

Answer 5

An outer tube placed over the exiting exhaust gas creates a venturi effect that draws more airflow over the engine

Answer 6

fully open

Answer 7

Manual, hydraulic or electrical

Answer 8

Consult MMM. If damage is excessive, the cylinder should be repalced

Answer 9

The movement must be within tolerances to keep cylinder head temperatures within allowable limits

Answer 10

Engine compressor

Answer 11

Air passing through the engine. Bypass air

Answer 12

The higher the combustion temperature, the higher the amount of power that can be produced up to the limit

Answer 13

75%

Answer 14

Multi feed internally cooled blades with film cooling
