2.2.3. Transmission Body
Transmisaion body (6) is the lower cover of the oil pump and. -the flange for mounting the governor on the
engine gearbox case.
Oil is fed from the engine to the governor and from the governor to the airscrew via internal routes for which
purpose the transmission body flange has three holes (1), (2), (4) (Ref. Fig. 4).
The transmission body and oil pump body are interconnected by two coupling screws (3), (5). The joint
between the oil pump and transmission bodies is sealed by a silk thread placed on sealant between the bodies.
3. OPERATION
The R-2, aeries 04, governor operates only with direct-action airscrew at one-way regulation scheme.
The airscrew blades are shifted to a smaller pitch by the pressure of oil fed by the governor to the airscrew
cylinder.
Shifting to a higher pitch is performed by counterweights installed on the airscrew blades; in this case the
governor returns oil from the airscrew cylinder to the engine gearbox case.
3.1. ENSURING CO
NST
ANT PRESET SPEED OF ROTATION OF AIRSCREW AND
POWERPLANT
With the governor operating, the oil from the engine line is fed to the locating flange of the governor and then
via passage (8) (Ref. Pig. 5) to the inlet of oil pump (7).
The pump increases the of. pressure to a value required for normal operation of the airscrew and feeds oil to
the space between two shoulders of slide valve (6) from which it is fed to the airscrew for changing its pitch.
Fig. 5 shows schematic diagram of governor operation under steady-state conditions when the engine power
and progressive speed of the airplane remain constant and the governor maintains the required constant speed of
the engine.
Under steady-state conditions rotating weights (2) are forced by centrifugal effect to turn on their axles and
lift slide valve (6) upward, while spring (3) of the governor forces the slide valve down. Thus. position of slide valve
(6) is determined by relation between centrifugal forces of weights (2) and force of spring (3).
In the case being discussed the spring tension force is equal to the weight centrifugal force.
