7.10 Power Unit
7.10.1 General
The engine ROTAX 912 ULS (100 hp) is used to power SportStar MAX airplane.
ROTAX 912 ULS is a four-cylinder, four-stroke engine with opposite cylinders,
central cam shaft, OHV valve mechanism and maximum take-off power of 100
hp (73.5 kW) at 5800 RPM.
The in-flight adjustable, composite, 2-blade propeller IDROVARIO HS is
standard mounted on the engine ROTAX 912 ULS.
7.10.2 Engine Control
Engine power is controlled by means of throttle lever (
GAS
), which is located in
the middle of the instrument panel and which controls engine power range from
idle up to maximum take-off. Engine power controller is mechanically
interconnected with the flap on carburetors.
If the lever is fully pushed in, then this position corresponds to maximum engine
power. If the lever is fully pulled out, then this position corresponds to idle. Rapid
changes in engine power setting can be made by pressing down the round
button on the lever body and by its pulling out or pushing in. Small changes in
power setting can be performed through lever turning (counterclockwise - power
increase).
The lever is fitted with the locking ring, counterclockwise turning of which
ensures locking of the lever in requested position.
7.11 Propeller Control
Propeller pitch is controlled by means of the propeller control lever
(
PROPELLER
), which is positioned on the right of the throttle level. Propeller
control lever is marked blue color.
If the propeller lever is fully pushed, the propeller blades are set to fine (low)
pitch position. If the throttle lever is fully pulled, the propeller blades are set to
coarse (high) pitch position.
Rapid changes in the propeller pitch setting can be made by pressing the button
on the lever body and by its pushing and pulling. Small changes in the pitch
setting can be made by turning the lever (clockwise = low pitch).
