Q

What is the difference between a supercharger and a turbocharger?

A

•Supercharger
–Driven directly by the engine via gears or belts.
–Compresses the fuel/air mixture AFTER it leaves the carburetor.

•Turbocharger
–Driven by high velocity exhaust gases that are passing through the exhaust system.
–Compresses the induction air BEFORE it is mixed with fuel from the carburetor.

91
Q

What are the two biggest disadvantages to a super charger?

A
  • Uses a significant amount of engine power

- More complex maintenance and failure wise

92
Q

Explain the difference between a turbocharged and turbonormalized engine.

A

Turbocharged
›A turbocharged engine has boosted manifold pressure above ambient sea level pressure, increasing the amount of power the engine is capable of producing.

Turbonormalized
›A turbonormalized engine compensates for the loss of ambient sea level pressure as the aircraft’s altitude increases.

›This allows the engine to maintain sea level rated horsepower up to very high altitudes. It does not increase the amount of horsepower the engine is capable of producing.

103
Q

The anti-feathering pins prevent feathering below what RPM?

A

950

104
Q

How long does it take to unfeather the prop?

A

8-12 seconds

105
Q

The oil stored in the accumulator is at what PSI?

A

90-100

106
Q

What is the difference between Synchronize and Synchrophase

A
  • Synchronize means to have both propellers at the same RPM
