leg mounted ripcord system

Recommended Posts

At the PR boogie I had a thought, would it be possible to mount a spring-loaded pilot chute on your leg & use a ripcord system?
Kinda like the base-pc option on the vampire, only with a ripcord & spring loaded pilot chute instead of a throw-out. I suppose the spring would be pointed diagonally out to the side instead of straight behind like on a regular ripcord system.
Seems like the dimensions of such a system would have to be tightly controlled...
Thoughts?
My advice is to do what your parents did; get a job, sir. The bums will always lose. Do you hear me, Lebowski?

My first though on reading this post is "why?" Although I think you may have had a reason when you explained it to me in PR, it is not obvious in this post...



yeah your true intention seems to have been lost, since i'm confused as to why.

With a throw out you have to let go of the pilot chute. With a ripcord/spring mounted PC you don't have to let go of the ripcord handle (and you probably shouldn't...)
What if you had something else in your hands when you wanted to deploy your parachute? With a throw out you could risk an entanglement.
I'm thinking about wingtips. Rigid styrofoam or plastic or whatever extensions with a bicycle grip for increased wingspan. In an emergency situation you could just drop the wingtips...but in an ordinary situation you might want to keep them. So the first obstacle I can think of is how to deploy the main if you've got your hands full of wingtips.

I've wondered about spring loaded pcs before, like a crazy system where you just join your thumb and forefinger and it gets fired out. I'm not saying it's a good idea! But it would allow you to deploy from absolute full flight, without reaching for the boc or BASE pouch.

i'm just curious why you would not want to let go of any handle for ta wing extension when you are getting ready to deployment. The amount of performance you would lose by doing that wouldn't really matter. I guess it would really depend on how much longer you would make them and still get added performance from it.

Hee!

Here we go again.
Reinventing the wheel.
The primary reason spring-loaded main pilot chutes disappeared during the late 1970s was the massive burbles created by the massive suits (Kreuger Balloon Suit, etc.) that were fashionable back then. Those huge suits created such massive burbles that spring-loaded pilot chutes hesitated for several seconds before they did anything ... like lift a d-bag out of your container.

I'm entertaining the thought of holding on to such wingtips because I'd like to reuse them. If you let go of them, you lose them unless they are tethered or somehow integrated into the suit... What I originally had in mind was for them to be entirely separate from the suit....
Seems like having them tethered would be a Bad Idea from an entanglement perspective.

Hmm... that's no fun. Do you know if they ever tried to mount the pc away from the container, and/or angle the spring away from the burble?

Are you talking BASE or skydiving? In BASE I would want to throw the PC and make sure that it is not in the burble.

Along similar lines, I have thought of a tabbed 'wing cutaway' style leg pouch cutaway; In case you have an impossipul, you can chop off the pouch and kinda tilt or chop wings or whatever to get the air to extract the PC or have a spring throw the PC sideways.

Rob you are not the first rigger /long time jumper that brings up this very juicy but forgotten by the newer jumpers historic fact. I've heard several "new things with springs" concepts floated by new visionaries. Much to the grumbles of riggers and jumpers that can recall the older gear.[:/]

But yet I haven't heard the concept utilizing a large explosive charge like in the ballistic recovery chutes used to softly bring back an entire aircraft. That will teach that pesky burble. :D

Yes, as a rigger, there is only one spring needed, on the reserve. And I'm sure the packers of years ago, before student throw-outs, will attest to hating to have to pack them also. ;)
