SECTION 7 - SYSTEM DESCRIPTION
7.1
Introduction
This section contains the description of the gyroplane and its standard systems and
equipment. Optional equipment is described in Chapter 9 of this manual.
7.2
Airframe and Undercarriage
The load carrying structure of the gyroplane consists of a composite monocoque occupant
enclosure which is connected to the rotor tower and keel tube. The composite structure,
tower and aft extension carry all loads induced by the crew stations, engine, rotor,
undercarriage, stabilizer, and serves as installation platform for additional equipment.
Stabilizer structure with rudder is made of CRP and is bolted to the aft extension of the keel
tube. Attachment points for the engine installation are provided by a steel tube ring mount at
the rear of the firewall.
The landing gear consists of a steerable nose wheel in a steel fork and two main wheels
with hydraulic brake system. Both main wheels can be equipped with wheel spats made
from GRP and are mounted to the ends of the spring spar, which is made from GRP. The
spar is designed to absorb even higher than normal landing loads in case of a hard landing
or crash.
7.3
Doors, Windows and Exits
This gyroplane features one large undivided glazed canopy and two hinged doors with
locking mechanism at the left hand and right hand side. The locking mechanism can be
operated from the inside and outside by moving an aluminium locking lever. The door is
properly locked when the lever jumps sidewise into its locking detent.
Two versions of the door lock are installed.
Body series I has two pins per door that slide into holes in the body, operated by the door
lever
Body series II has a slam-shut door system utilising spring loaded catches.
Two adjustable fresh air vents one on each side and one sliding window per side with
pivoting vent are provided for ventilation. The sliding window can be used as viewing hatch
in case of emergencies and is wide enough to reach through with a hand.
The gyroplane is embarked and disembarked from each side while the doors are held open
by a gas spring. In case of emergency the opposite door may have to be used to disembark
the aircraft.
In order to close the door, pull the door close, move/lead the locking lever from ‘Open’ (aft
position) to ‘Close’ (forward position) and let the lever snap sidewise into its locking detent.
Do not close doors by pulling at the opened sliding window as this may result in breakage of
the Plexiglas. Only use the grip or recess provided for that purpose and operate locking
lever with second hand while pulling door close.
For slam shut doors, simply smartly close the door using the pull handle.
