Now in the mind of a lot of pilots, this can only work with reflex profiles because this is what they’ve heard from other brands.
Fortunately for us, Marketing is not always the truth.
Just like with trimmers and speedbar, you can adjust the AOA of your glider through this device!
Reflex profile: Reflex is qualification for a profile that have tendency to increase its AOA when you leave it “free” (Cm positive).
This is helpful when you lower a lot your AOA to avoid negative incidence on it (which you can anyway get if you get hit by a strong turbulence) therefore reduce the collapse possibilities.
The amount of reflex is not a binary data, it’s an intrasect airfoil characteristics depending on a lot of factors on its design (intrados/extrados/camber…).
In no case, these profiles are 100% collapse proof. They will all at some stage, often without warning, generally at low AOA, and with pretty bad recovery behaviour most of the time (look at Paramotor crash videos on YouTube or so).
The stronger the reflex effect is the worse the efficiency is (so is the handling)!
The advantage is that you can use them a lower AOA, therefore fly faster than a regular profile.
My 20+ years of experience in foil kites design teach me that there are other ways to get stability (to a certain point of course)!
Inside pressure, tabs positions, canopy skin tensions, micro deformation of the canopy under certain circumstances…
And you know what, since day one, I’ve been working on making LC wing as pitch stable as possible, without using a strong reflex profile.
To LC opinion, being saved by the glider or worst, relying on it to be safe is a very inappropriate way of approaching the safety.
By essence a turbulence is invisible, moving, its intensity can’t be appreciated in advance. Of course, you can guess… But who never got surprised by a collapse…
I believe so that active piloting is a fundamental requirement for safety (for whatever flying discipline), especially when you fly close to the ground!
I believe that it’s important to have good feedback from your glider to understand the air and react (prevent the collapsing to happen) when needed.
So yes, flying a glider with Kiterisers system requires some experience!
