PILOT OPERATING HANDBOOK
Chapter 4
Normal procedures
4.1 Introduction
Chapter 4 contains a list of activities and a description of procedures for
performing normal operations. Normal procedures relating to the optional systems
are included in Chapter 9.
4.2 Attaching the Rotor
Insert the rotor blades into the sockets secured by five bolts on each side of the
hub. The five M8x65 bolts, each with washers on both sides, are fixed to the
hub beam with each blade. Next, first tighten and then fully screw in all ten nuts.
Equalize the rotor blades by using stretched string, passing through the centre
of the hub and along the grooves on the blade tips. The rotor must be placed on
two supports with a soft surface to avoid damage, so that the strained string is
about 1 cm above the central opening in the hub. When the string does not
overlap the hub axle, two people are needed for help hold down the blade tips.
Then push the hub into the right direction. After alignment, tighten the nuts with
a torque spanner, first 18 nm, next 24 nm. If the engine is not aligned properly,
unwanted vibrations in flight will occur.
The correctness of alignment must be checked on the first flight.
Installation of the Rotor on the Gyrocopter:
•
Make sure the wheel brakes are activated (postion 1).
·
•
Fix the control stick in the extreme forward position so
that the rotor head disc rests on the brake.
