Please
note that the wind direction in this photo sequence
almost perfectly aligns with the dirt road.
This
paraglider launch technique is great for high winds. The
goal of this launch is to eliminate the huge traction
that occurs during a the paraglider's ascent to overhead
during a standard inflation. In a standard inflation,
with the paraglider directly downwind for the pull up,
it will come up violently and can overfly and yank the
pilot into the air. In the cobra technique, the wing avoids
both of these scenarios, as it comes up slower on the
side. Kitesurfers launch their parafoils from the side
like this and this is where my thought of this technique
came from.
I
first tried this technique, yesterday, April, 2nd 2005.
I had been thinking about how this would work for quite
some time, but had not actually practiced it. It was blowing
about 15 avg with gusts to 18+. I had recently been to
Utah, and when I described this concept to Steve Mayer,
he referred to this as a common practice at Point of the
Mountain for high winds and that they called it the Cobra
Launch technique. They had already been
using it for a while. He said almost all of the many tandem
pilots use it for higher wind days as well.
The
pictures here are my first successful attempt at this
technique after only 1 failed try. I have not seen any
of the regulars use this ever, so think it will have some
strong benefits for those of us at the coast, launching
on higher wind days. I have since taught some of the students
with some kiting basics and consitently they learn it
in just a couple of tries. |

I
laid the wing out about 20 - 30 degrees off of perpendicular
to the wind with a bit of arc at the right tip. The wing
is almost perpendicular to the camera angle in this picture.
For lifting the wing, I use my right hand on the wing's
left riser (the one crossing to the right, downwind, side
of the wing as you face it). The right side brake is in
my hand in the preset hands mode. In my left hand is the
left brake.
On
a later date, I tried lifting the left A riser with the
left hand and this freed up the right hand to pull the
D riser on the left side of the wing instead of using
the left brake. I could not get the D riser to get the
wing to ascend as it did with the brake. So, stick with
the above technique. |
The
inflation is done in the normal fashion, but only lifting
on the wing's left riser. Once the wing reaches the position
pictured, enough brake needs to be maintained to keep
the wing in this vertical position. The amt. of brake
to pull can suprise you, it takes a fair bit. to manage
this angle at this point. If the wind is strong enough
to warrant this technique, the wing will then basically
walk its way up, like a Cobra, and you can just direct
it up overhead.
When
it is a little lighter winds than this, I have subsequently
found that see-sawing (pulling some A, then some brake
repeatedly) can help get the wing overhead. |
You
can see in this picture that the left brake is pulled
pretty deep to steer the wing overhead. The wind direction
is almost straight up the dirt road in the picture |
Notice
that there is still some pull during inflation, but way
less than an "eye of the wind" inflation. You
can see that I was pulled accross the distance of the
road between the above pictures and this one.
