Power Augmentation

Question 1

What are the two types of chargers increase power augmentation within a piston engine?

Answer 1

Turbo charger and a super charger.

Question 2

What does the Manifold absolute pressure measure the pressure of within a piston engine?

Answer 2

Cylinder pressure.

Question 3

At idle speed there will be the blank map gage.

Answer 3

Lowest.

Question 4

When the butterfly is open what happens to the pressure?

Answer 4

It reduces.

Question 5

Higher the power, the blank the map.

Answer 5

Higher.

Question 6

Less difference in pressure on the map, the blank power in the engine.

Answer 6

More.

Question 7

As you climb, atmospheric pressure decreases therefore power blanks in the engine.

Answer 7

Increases.

Question 8

Blank blank is when the pressure of the aircraft matches the atmosphere.

Answer 8

Performance ceiling.

Question 9

Whats it called when the boost value reaches 0 psi?

Answer 9

Critical altitude.

Question 10

Ground boosted is a type of power augmentation. It blanks with increasing altitude.

Answer 10

Decreases.

Question 11

Attitude boosted boosts above a given altitude. What altitude is this?

Answer 11

6000ft.

Question 12

What is the turbo charger driven by?

Answer 12

Exhaust gasses.

Question 13

What is the super charger driven by?

Answer 13

Crankshaft.

Question 14

The waste gate is located within the turbo charger. What does this control the speed of?

Answer 14

Turbine speed.

Question 15

As the turbine slows down within the turbo charger waste gate, the pressure blanks.

Answer 15

Decreases.

Question 16

If the waste gate is closed do you get more or less power?

Answer 16

More power.

Question 17

What is a turbocharger used for in a piston aero-engine? (Map and altitude)

Answer 17

Compensating for a decreasing MAP with increasing altitude.

Question 18

The air source for the vapour-cycle machine in a piston engine airplane is…

Answer 18

Compressor

Question 19

When detonation is recognised in a piston engine, the correct procedure is to increase/reduce manifold pressure and fully enrich/lean the mixture.

Answer 19

Reduce and enrich

Question 20

Assuming the RPM and throttle levers are not altered, when TAS increases the blade angle of a constant speed propeller will increase/decrease.

Answer 20

Increase.

Question 21

A turbocharger in a reciprocating engine consists of a blank and turbine mounted on a common shaft.

Answer 21

compressor and turbine mounted on a common shaft.

Question 22

A turbocharger in a reciprocating engine consists of a compressor and blank mounted on a common shaft.

Answer 22

Turbine

Question 23

The air in a piston engine turbocharger enters the centrifugal compressor at…the eye of the impeller and leaves it almost at a tangent to the blank

Answer 23

Periphery.
