Brake Lines - Ozone ALPINA 2 Handbuch

YOUR ALPINA 2
The Alpina 2 is based on the Delta 2 but constructed with light
weight materials. It has directly benefitted from the technological
gains made in the Ozone Performance Research Project - our Open
Class series along with the lightweight construction R&D employed in
the XAlps series of wings.
Ozone's research in light wing construction began with the Peak in
2001, continued during the first ever X-Alps race in 2003 and every
subsequent race since. Features that appear in the design of the
Alpina 2 helped pilots sweep the field in the 2013 race.
The Alpina 2 retains the comfort, safety and ease of use of the
Delta2 but increases the overall performance, fun and handling in a
lightweight package. The Shark nose profile is solid at accelerated
speeds and extremely resistant to spin and stall. It provides a more
constant internal pressure in turbulent air, increasing passive stabil-
ity and creating an even more comfortable and stable feel especially
during accelerated flight. The new profile has also improved the
launch behaviour by reducing shooting in higher wind conditions.
True Performance is our quest, and with the Alpina 2 this means
a speed range that is fully usable in real conditions. Ultra-smooth
Ronstan pulleys make engaging the speed bar, and maintaining pitch
control via the bar a pleasure in active air.
R12/Enzo style mini ribs at the trailing edge and a new internal
structure to support the advanced line plan have resulted in a huge
reduction in parasitic drag. Further line optimisation has reduced
the overall total line drag by 26% compared to the original Alpina,
this higher level of efficiency and clean shark profile has allowed for a
significant wing area reduction.
Suitable for Sport Class pilots who are looking for a light weight wing
with maximum performance without compromises. The Alpina is for
serious adventures and XC missions in real conditions anywhere on
earth.
Rucksack
The bag is light in weight, comfortable and useful (padded hip belt,
ergonomic and adjustable shoulder straps). It has a large volume that
will allow you to store all your kit, whilst still being comfortable for
hiking.

Brake Lines

The brake line lengths have been set carefully during testing. We feel
it is better to have slightly long brake lines and to fly with a wrap
(one turn of line around the hand). However, if you do choose to ad-
just them, please bear in mind the following:
• Ensure both main brake lines are of equal length.
• If a brake handle has been removed, check that its line is still
routed through the pulley when it is replaced.
• When the brake handles are released in flight, the brake lines
should be slack. There must be a substantial "bow" in them to
guarantee no deformation of the trailing edge.
• There must be a minimum of 10cm of free play before the brakes
begin to deform the trailing edge. This prevents the trailing edge
from being deformed when using the speed system.
IMPORTANT: In the unlikely event of a brake line snapping
in flight, or a handle becoming detached, the glider can be
flown by gently pulling the rear risers (C-risers) for direc-
tional control.
Risers
There are 2 different riser options available: Standard and Light-
weight.
Standard risers are made from 12mm black Cousin webbing and the
lightweight version from 7mm Dyneema. Both options use specially
designed 'Link Lite' connectors to hold the riser lines. These are
tested to over 500kg and save approximately 200gr compared to
standard maillons. The lightweight option also features smaller and
lighter brake handles.
