2.1. COOLING SYSTEM
The engine is cooled by air, water and oil (mainly used as a lubricant) systems. The engine is
equipped with water and oil radiators. Air intakes on the engine cowling ensure the correct air
distribution around cylinders and radiators. Air flow around radiators and engine cooling surfaces is
assured by the low air pressure generated by the extraction lip on the lowest part of the engine
cowling. The cylinder heads are cooled by cooling liquid that is circulated by mechanical pump built
into the engine.
NOTE
For engine liquid specification refer to engine supplier
documentation.
CAUTION
WATER OR COOLANT CONTAINING WATER
MUST NEVER BE ADDED TO WATERLESS
COOLANT (E.G. EVANS). FOR COMPLETE
COOLANT SPECIFICATIONS REFER TO ROTAX
DOCUMENTATION.
2.2. LUBRICATION SYSTEM
The lubrication is ensured by a circulation of oil which is pressurized by a mechanical oil pump. An
oil tank is attached on the left side of engine mount. The oil pump sucks the motor oil from the oil
tank, via the oil cooler, and forces it through the oil filter to the points of lubrication in the engine.
Minimum and maximum quantity of lubricant at take-off is 2 - 3 liters.
NOTE
The specifications of the motor fluids are contained in
the documentation provided by ROTAX.
2.3. PROPELLER
The aircraft is equipped with the following propellers:
Standard configuration:
DUC Helice FLASH: 3 carbon fiber blades, variable pitch on the ground
Optional:
Ivoprop Medium: 3 blades in composite material, in flight electric variable pitch.
