TECHNICAL DESCRIPTION, OPERATING, MAINTENANCE AND REPAIR MANUAL
1.6.10.2.5 Oil
Oil grade: motorcycle oil of a registered brand with gear additives. Use only oil
with API classification „SF“ or „SG“! If using aircraft engine oil,
than only blended one. Due to the high stresses in the reduction
gears, oils with gear additives such as high performance motor cycle
oils are required. Heavy dry 4-stroke motor cycle oils meet all the
requirements. These oils are normally no mineral oils but semi- or
full synthetic oils.
Oil capacity: 3,0 litre
Minimum: 2,0 litre
Oil consumption: max. 0,1 l/h
WARNING
Never use AVGAS LB 95 with mix full synthetic engine oils.
At the selection of suitable lubricants refer to the additional information in the
Operator’s Manual for all versions of ROTAX 912.
1.6.10.3 Propeller
Standard version of aeroplane is equipped with SR 2000 is the three blades, in flight
electrically adjustable aircraft propeller of a mixed structure. The propeller blades are
made of a wood and the leading edges are made of a wear resistant material.
The angle of blades setting is adjusted by servomotor controlled from the cockpit and
it can be adjusted smoothly in range from the minimum angle intended for take-off up
to maximum angle. The momentary blade angle is designated by a time of displace
from 16° lower blade stop ( measured at 0,75 of a propeller semi-diameter ). A speed
of displace is 0,5 °/sec. Propeller control on the instrument panel consists of panel, in
which there is placed the signalisation of the direction of propeller blades adjusting,
together with control diodes of small and large angle and also the switch of control.
The meaning of the control diodes signals is:
Yellow control diode of adjusting the fine angle:
- shines after reaching the stop at 16°, i.e. min. angle
- blinks when adjusting the fine angle
Red control diode of adjusting the rough angle:
- shines after reaching the stop at 26°, i.e. max. angle
- blinks when adjusting the rough angle
Propeller Technical Data:
Propeller Diameter: 1700 mm
Propeller Blade Angle: 16 ÷ 26° (Range of setting angles is
adjustable)
Max. Propeller Speed on ground: 2550 rpm
Max. Propeller Speed in flight: 2600 rpm
Max. Propeller Speed on testing stand: 3200 rpm
Propeller Mass: 7,8 kg
Time Between Overhaul (TBO): 1500 hrs
