1. Description of components and systems
NOTE:
Further descriptions and assembly are provided on sections 1.4, 1.5, and 7
of the Flight Manual.
1.1 Airframe
The model Ventus-2a and Ventus-2b are single-seat high performance sailplanes,
constructed from fiber reinforced plastic (FRP), featuring wingflaps
and a T-tail (with fixed horizontal stabilizer and elevator).
Wing
The wing shells are a CFRP/foam-sandwich with spar flanges made from
carbon fiber rovings and shear webs constructed as a CFRP/foam-sandwich.
Fuselage
This is a pure carbon fiber lay-up with a Kevlar and glass fiber reinforcement
in the cockpit area for high energy absorbtion.
Horizontal tailplane
The horizontal tailplane consists of a fixed stabilizer with elevator.
The stabilizer is a GFRP/foam-sandwich, the elevator halves are a pure
carbon fiber lay-up.
Vertical tail
Both fin and rudder are constructed as a glass fiber/foam-sandwich.

2.2 Weights and hinge moments of control surfaces
After repair work or repainting, the hinge moment of a component must not
and its weight should not exceed the following values:
Component Weight Residual moment
Rudder with mass
balance
1 Elevator half with mass
balance without fitting
Flap / inboard
aileron
Mid aileron with
mass balance
3.90 - 4.80 kg
8.60 - 10.58 lb
1.00 - 1.25 kg
2.20 - 2.76 lb
1.50 - 1.85 kg
3.31 - 4.08 lb
2.00 - 2.50 kg
4.41 - 5.51 lb
Outbd. aileron 0.54 - 0.66 kg
1.19 - 1.46 lb
(-3.00) - (1.00) cmkg
(-0.22) - (0.07) ftlb
0.25 - 1.40 cmkg
0.02 - 0.10 ftlb
7.00 - 8.50 cmkg
0.51 - 0.61 ftlb
2.70 - 3.50 cmkg
0.20 - 0.25 ftlb
1.50 - 1.90 cmkg
0.11 - 0.14 ftlb
If the values shown in the above table are exceeded, it will be necessary to
add an additional balance weight forward of the hinge axis as follows:
1. After repair work - in the area of the repair
2. After repainting - in the repainted area
After complete repainting – distributed along the whole length of the
component (if there was no mass balance attached) or near or next
existing mass balance.
Exceeding the value in the above weight table because of additional mass
balance is permissible up to 15%, provided the residual moment within the
tolerance.

2.3 Play in the control circuits
With the cockpit controls fixed, the play at the control surfaces must not exceed
the following values:
Inboard +/- 2.0 mm measured 126 mm behind hinge axis
aileron: (+/- 0.08 in.) (4.96 in.)
Between inbd.
and mid +/- 2.0 mm measured 106 mm behind hinge axis
aileron: (+/- 0.08 in.) (4.17 in.)
Between mid
and outbd. +/- 1.0 mm measured 88 mm behind hinge axis
aileron: (+/- 0.04 in.) (3.46 in.)
Elevator: +/- 3.0 mm measured 138 mm behind hinge axis
(+/- 0.12 in.) (5.43 in.)
If there is excessive play in the hinge bearings and/or linkages, they must be
replaced or the manufacturer should be contacted regarding possible measures
to reduce the play.
The rudder control circuit is an open circuit, operated directly by control cables,
and is therefore not subject to play.
