What does a condition lever do?
A Condition Lever is a pilot actuated control which is located within the throttle quadrant of a turboprop engine equipped aircraft. It is utilised to control some functions of both the propeller and the engine. These functions vary from installation to installation.
How fast do turboprops spin?
The high pressure compressor and turbines of an airliner engine will run at above ten thousand RPM, while the propeller of a large turboprop engine wants to run at about 1700 to 2200 RPM, and in case of the NK-12 of the Tu-95 the propellers run at only 750 RPM.
How does a governor work aviation?
The governor maintains the required balance between all three control forces by metering to, or drain from, the inboard side of the propeller piston to maintain the propeller blade angle for constant speed operation. The governor operates by means of flyweights which control the position of a pilot valve.
How high can turboprops fly?
between 25,000 and 30,000 feet
While commercial aircraft typically fly between 31,000 and 38,000 feet, why do turboprops typically have service ceilings of less than 30,000? The answer is that turboprops are most efficient at an altitude between 25,000 and 30,000 feet.
Does turboprop count as turbine time?
All turboprops, singles and twins, are turbine. Caravan, PC12, TBM, etc are single engine turboprops, which is turbine time.
What happens when a prop governor fails?
Governor Failures—Overspeed Wild changes in prop rpm in flight can signal loss of governing control, forcing the blades into the fine or high-rpm pitch settings. When this happens, get the engine speed down before it does any damage.
How does a CSU work?
Constant speed propellers work by varying the pitch of the propeller blades. As the blade angle is increased, it produces more lift (thrust). At the same time, more torque is required to spin the prop, and the engine slows down.
Is the PC12 turbine time?
Caravan, PC12, TBM, etc are single engine turboprops, which is turbine time. King Airs, Cessna Conquest, etc, are examples of twin turboprops, which are turbine.
