Operation Manual

Example
model:
"CORTINA"
"Cortina"
is a typical example
of a modern tailless
glider.
Control
is
achieved
with two control surfaces
per
wing
panel,
each surtace working as combined elevator
and
aileron
(elevons).
This
arrangement
makes it
possible
to
achieve
tavourable lift distribution in all flight situations.

The mixing ratios for elevator and aileron
are different for
the inboard and outboard elevons.
A
seoarate
servo is re-
quired
for
each elevon.
Airbrakes are included
for height
dumping and
landing approach control.
The
aerotow
coupling
is actuated via a switched channel.

Possible modifications:
Control of airbrakes
via slider
instead of stick. Use
oJ a lreely definable
mixer instead of
the
"

This arrangement
would allow automatic
