5. Calage variations app
This application allows us to see how the wing's calage varies when
varying the relative angle of attack, with respect to the initial
position (30%). The angle of 0º corresponds to 30%. The input values
are negative rotation angles (counterclockwise decrease the angle of
attack), and positive rotation angles (clockwise increase the angle of
attack). In this application we consider that the rotations are around
point A, which is fixed. The SB and SC distances are the lengths that
risers B and C must be extended (negative values) or cut (positive
values), for the indicated calages. The wing maintains stable flight in
a given calage range, which is what we are trying to determine
experimentally in flight. Remember that a parakite is mainly controlled
by varying the angle of attack or calage of each half-wing. Thus, the
adjustment is more difficult than a fixed calage wing.

Note: This app is customized to the parameters of the Swoop 18.
I plan make a general app version to study any profile or paraglider wing.
Prototype number #1 by Tim Weber, Germany
https://www.instagram.com/thermik_timmy/).
Thierry Bosq has already started building his Swoop 18 prototype, in orange and white!
And a third prototype (Swoop 22) planned in China!
LAB NOTE: Build
a paraglider at home is a
very complicated task (even simple
skin), and requires many
hours of work. Previous experience is required, and very inventive.
As always remember that:
The free flight implies risks
that can only be known and they can be controled with a suitable formation on the part of a recognized school.
Not test wings without knowing their functioning. The
construction and test of experimental wings without certifying requires
deep knowledge of what is being made.
