4.10 ROTOR PREROTATION (Fig. 24)
CAUTION:
Keep the control stick fully forward until reaching 130 r.p.m. rotor speed.
1 - ALIGNMENT - runway alignment
2 - ENGINE SPEED - set at 1.800 r.p.m.
CAUTION:
A lower or higher engine speed may worsen the prerotation procedure
performances.
3 - PREROTATION ENGAGING - gently operate the prerotation lever (1).
Keep engine speed at 1.800 r.p.m.
CAUTION:
The prerotation must be engaged in a gentle manner, without sudden
movements of the lever (1), so as not to stress the system and avoid stopping the engine.
At 130 r.p.m. ROTOR
4 - CONTROL STICK - Place the control stick (2) in takeoff position (rear limit stop).
5 - PREROTATION LEVER - Gently reach the limit stop while keeping a constant engine speed.
WARNING DANGER:
In windy conditions, or if the payload is light, it is possible
that the gyroplane will lift up onto the tail wheel. If this occurs, the prerotation should be
released and the stick moved forward to balance the gyroplane on the main wheels, some
engine power should be applied to prevent the gyroplane from moving backward. The rotor
rpm will continue to increase. When the rotor speed is equal or greater to 200 rpm, proceed
as for take off. This should be practiced with an instructor before proceeding in these
conditions
AT LIMIT STOP OF PREROTATION LEVER
6 - ENGINE r.p.m. - Gently increase the engine speed until reaching 200 r.p.m. of the rotor.
(standard prerotation).
WARNING DANGER:
The minimum rotor prerotation speed is 150 r.p.m. It is strictly
forbidden to proceed with
takeoff operations if the rotor r.p.m. is lower than the minimum
value.
NOTE:
Under identical conditions, the length of the takeoff run depends on the rotor
r.p.m. reached during prerotation.
The maximum speed of the prerotation system is 280 r.p.m.
The life of the prerotation system and its inspection frequency depend on the average rotor
r.p.m. applied during the prerotation operation.
