Thanks, to regis and you, for supporting so many good ideas through the years!
right, getting rid of C would be pretty straight foreward - I had a day in NL, when I disconnected the C bridle at their ECLs pulling C and half the mixer out!
Result was not so good. The underpressure in the area of C is still so strong that profile needs C support to stay in shape. So empiric result says 'no' to this mod at a15.
On one hand predictable, on the other surprising:
The tip part of a profile is more sensitive against (underpressure) deformation than the front part of the wing (The B bridle connection works up to nearly 50% of profile depth, but we need more support from 50% to 100% (at the back part) of profile)
This leads to a particularly sense of a 'backweigthed mixer' - it handles exactely this point!
So I'm a little irritated at the moment - I think, designs with repositioned B (45-50%) and C (70-75%) and Z (as ever) in combination with a backweighted mixer may be better for profile in general!
In panshs products this works just for pansh a15, aurora II and aeolus have more conventional connection points .
BtW1: A nice guy gives me hands on an aeolus next month, hopefully. I'm pretty curious to measure and document some results here...
BtW2: Recently I stumbled in a very valuable old post from you regarding sealing of old canopys with 'shoe goo'.
One collegue gave me an old speed 3 to bring it back to life. I set the lines back to their original length and we had a nik wax wash but filling of the kite is still pretty lousy - garment is still porous after one wash.
Now after this first repairs the tips won't fill completely in static flight (still flattering), and kite refills bad after power / depower actions). You dont know shoe goo works after nik wax session, or have you a better technic developed? (perhaps pm reference to another post?)
By now I think ram pressure is a (little) design problem in S3 kite design, too - so it is a little sensitive against aging porousness effects.
So next to porousness I will experiment with the intake flaps to improve ram air flow into the kite. May I am right?
