  • Page 4 Propeller Owner's Manual 115N WARNING (Rev. 2) People who fly should recognize that various types of risks are involved; and they should take all precautions to minimize them, since they cannot be eliminated entirely. The propeller is a vital component of the aircraft. A mechanical failure of the propeller could cause a forced landing or create vibrations sufficiently severe to damage the aircraft, possibly causing it to become uncontrollable.
  • Page 5 Failure could be as severe as loss of propeller or propeller blades and cause loss of propeller control and/or loss of aircraft control. Hartzell Propeller Inc. follows FAA regulations for propeller certification on certificated aircraft. Experimental aircraft may operate with unapproved engines or propellers or...

    Propeller Owner's Manual 115N 1. Description of Propeller and Systems A. System Overview (1) The propellers covered in this manual are constant speed, single-acting, hydraulically actuated propellers. Some of the propellers have feathering capability. These propellers are designed primarily for use with reciprocating engines, but there are some turbine applications.

    Propeller Owner's Manual 115N (6) Oil under pressure from the engine-driven governor is supplied to the hydraulic cylinder through the pitch change rod. Increasing or decreasing the oil volume within the hydraulic cylinder either increases blade angle to reduce engine RPM, or reduces blade angle to increase engine RPM.

    Propeller Owner's Manual 115N C. Constant Speed, Feathering Propellers ( )HC-( )( )Y( )-2 (1) Refer to Figure 2-2. The -2 Series propellers are constant speed propellers that use an air charge, spring, and counterweights (if installed) to move the blades to high pitch/feather position.
  • Page 68 Propeller Owner's Manual 115N (7) When the engine is stopped on the ground, it is undesirable to feather the propeller, as the high blade angle inhibits engine starting. To prevent feathering during normal engine shutdown on the ground, the propeller incorporates spring energized latches. If propeller rotation is approximately 800 RPM or above, the latches are disengaged by centrifugal force acting on the latches...

The -5 Series propellers are constant speed propellers that use an air charge, spring, and blade mounted counterweights to move the blades to high pitch/ feather position.
  • Page 74 Propeller Owner's Manual 115N (6) In some cases, particularly in seaplane applications, it is undesirable to feather the propeller when the engine is stopped after landing. To prevent feathering during normal engine shutdown, the propeller incorporates spring energized latches. If propeller rotation is approximately 800 RPM or above, the latches are disengaged by centrifugal force acting on the latch weights to compress the springs.

(2) The governor model number is stamped on the base and/or body of the governor assembly. (3) Refer to Table 2-3 for a description of the characters used in the governor model number.
  • Page 87: Unfeathering Accumulators

    This supplied pressure will lower blade angle which will cause the propeller to windmill and make the engine easier to start. (2) Hartzell Propeller Inc. manufactures an accumulator that is a cylinder with a moveable internal piston. One end of the cylinder and piston is filled with engine oil, and the other end of the cylinder and piston is filled with air or nitrogen to a designated pressure through an air valve.
  • Page 88: Electrical Models

    Propeller Owner's Manual 115N (3) Unfeathering occurs when the governor RPM control is moved by the pilot from the feather location to a higher RPM selection for governing. The governor disconnects the propeller oil supply from the drain and reconnects it to the governor oil supply line from the governor.
  • Page 89 Propeller Owner's Manual 115N (3) When the engine has shut down or failed, no oil is available from the engine oil pump to the governor; therefore, no governed oil is available from the governor for controlling the propeller blade angle and RPM.
