Pre-rotator lower engagement consists of the pneumatically activated belt and pulley clutch.
For pneumatic control of the clutch refer to CHAPTER 36 - PNEUMATIC .
63-11-20 Pre-rotator Drive
Power flow is realized through a 90-degree gearbox and two drive shafts. The 90-degree gearbox is
mounted to the mast. Both pre-rotator drive shafts features cardan joint and a sliding shaft coupling to
allow changes in length and alignment due to clutch kinematics and the tilt of the rotor head.
63-11-30 Pre-rotator Upper Engagement
The pre-rotator upper engagement comprises a drive pinion with bearing, which is engaged by a small
pneumatic actuator into the geared ring / sprocket wheel of the rotor head. The drive pinion is sliding
on a helical gear to provide automatic lock-out in case of rotor RPM overrun.
63-51-00 Rotor Brake System
The rotor brake system consists of a brake pad mounted to a bracket which is hinged to the rotor head
bridge. With the pneumatic mode selector in BRAKE position the operation of the pneumatic trim
actuator is reversed so that increased pressure causes the actuator to push the rotor head up (or
level) and presses a brake pad against the rotor head disc. In order to increase brake pressure, move
the 4-way trim switch to aft. Note that this action will also push the control stick forward. At full brake
pressure the control stick will be maintained in its full forward position.
Due to its main function the pneumatic brake/trim actuator/cylinder itself is allocated to 67-05-00 Pitch
Trim .
CHAPTER 64-66 - N/A
CHAPTER 67 - ROTOR FLIGHT CONTROL
Rotor flight control comprises of control stick, a base control unit /
tube, flight control base link and control rods (push rods) which are
connected to the rotor head bridge.
Pitch and roll of the gyroplane is controlled by tilting the complete
rotor head by means of the control stick. Control input is transferred
via a base control unit / tube running horizontally along the forward
extension of the main frame (below the seats) to the base link and
from there to the rotor head via control rods (push rods). The control
rods with ball joints at both ends are supported by a bell crank about
half way up the mast.
The control stick head is ergonomically shaped to fit the pilot’s right
hand and features control buttons for radio transmission (1), a four-
way trim function (2), and activation of the pre-rotator (3).
67-05-00 Pitch Trim System / Rotor Brake
The Pitch Trim System comprises of a 4-way beep trim switch (2) /
“Chinese Hat” at the flight control stick and the pitch trim / brake
pneumatic actuator. Pneumatic control is allocated to and described in
CHAPTER 36 .
Components related to the rotor brake are allocated to 63-51-00 Rotor Brake System .
Trimming is effected by varying trim pressure in the pneumatic trim actuator which is installed in
parallel with the rotor head tilt for pitch control. Aft or nose-up trimming activates the electrical
compressor and increases trim pressure, causing the actuator to contract, and tilting the rotor disc aft.
Forward trimming opens the pressure relief valve to reduce trim pressure and allows the rotor disc to
flatten, due to the spindle head offset and the gyroplane’s weight. The actual trim condition is indicated
on the trim/brake pressure gauge in the centre panel of the cockpit.
