Turbulences in opening?

Recommended Posts

First a little about my first acrobatic experience :)

This weekend i was again practising my wingsuit jumps on GTI. I had about 15 wingsuit jumps, and my exits, flights, openings were stable. As i had noone to fly with this weekend, i decided to start to do some simple acrobatics... By the book ("Skyflying Wingsuits in Motion" by Scott Campos, as i have limited access to wingsuit instrucors, book is irreplaceable resource for me, thanks again Scott ;)) i started to practise the frontal loop.
First jump i practised to fold legs and put them near chest and back as described in a book, and all times it came very well.
Second jump i wanted to try full frontal loop. I folded legs and put them to chest. Folded arm wings and went to frontal loop, BUT i unfolded a little leg wings while looping and when i was on my back i got thrown back on my belly, but i didn't loose stability, but just laughed, it was fun :)
Third jump i made it. I was all the time thinking, repeating and imagining in mind while sitting in airplane, "hold the legs, dont open them while in loop" and succeeded, i went to frontal loop, made it, then opened arm wings then leg wings, and i was stable again and flying towards the same point. I was smiling i was happy i could make it, i had so much joy and fun of learning and doing front loop. Definately will continue practising loop and learing new ones, while they gets more stable and smooth .Then it came time to start opening procedure...

Now about the problem.

I clapped with my legs, folded legs and put my arms on the rig, grouped my body as usually ... wait a little to loose horizontal speed and threw pilot chute, put my arms near wings cut-away handles, put head little up and waited for caopy opening as usual. I waited and waited, and it didn't came out, waited a little more, and still nothing. I had similar situations while in RW, than behind you creates tubulences? that pilot chute goes in to it and it has not enough power to get bag out of the rig. All i did is the same as before in RW - i started to change my body position, shake a little - right - left, so the air behind my body will mix and stop that turbulence - and it helped, after i did it, i felt usual opening feeling, bag going outside of a cointainer, and usual opening.

Trully i didn't liked this feeling of waiting and waiting and nothing happens (i guess it was for maybe 2-3 seconds but anyways i didn't like it and realize something is not as good as always) It was not so bad or scary, but i definately don't want such things happen too often :)

Does anywaone have experienced the same?
How to avoid it?
Maybe i didn't wait my vertical speed is enough, but then horizontal still should be quite big and there would be no such turbulences behind me...
Or maybe the rig is the problem? (Canopy and rig is by Russian producer, Canopy - Flamingo 150, Rig - Retal Golf 2, attached image)
Thanks.

If you bend your legs, chances are you're also speading them. This creates a huge burble behind you because of the open legwing. Keep your legs together, don't bend them so much, to avoid this.

The solution for a pilotchute in the burble: go back to full flight immediately (don't look). This will cause a full-flight opening (ie, brisk, not losing much altitude). You can always open this way (base-jumpers do) if you want, it will prevent this situation. Most people however find an in between since they don't like the brisk openings, but still open with some forward speed.

how is the Pilot Chute ? Size ? Age? Number of jumps ? condition of the fabric ?

I guess this could be right answer, it's the same thing i noticed about myself while practising front loop, when bending legs, i accidentaly am spreading them a little bit.

Also i was thinking about throwing the chute farer, advice. I am usually trying to make throwing move quite fast, so the opened arm wings wont affect my stability, i think i could throw it a little farer away than i do it now.

Will work on these two points next weekend.
Thanks.

About the rig container, i bought new system last autumn and have about 80 jumps on it, so condition is great. About pilot chute size, i really can't tell exactly, must measure it to tell correctly.

P.S. JohanW yes i haven't updated jumps a while, not 100 more, but some more it is.

yup, that seems to work. I usually throw the PC from full flight. The extra horizontal speed seems to take care of the burble and my lazy throw :P Actually I just replaced my old and tired standard Mirage PC for a brand new Cazer 28" zero-p with a longer bridal ... and didn't notice much difference in openings. But then again, my Firebird and Safire129 are a perfect match B|
