wings reserve pilot chute

[hunters 0]

I would like to hear from other riggers their opinions about the wings reserve pilot chute. Has anyone reported this going inverted on RSL deployments or cutaways at sub terminal?

Who wants to know?

Some personal bio info please. Who are you? What is your experience? And what what is the specfic nature of your complant? Most who post here like to know to whom they are talking to and why. Just common courtisy.

Mick.

what do you mean inverted exactly?

We are more than willing to talk about this, but you need to be more specific about what your objective is. Your question is so vague that we think you are a troll. Clear the air for us please.

My wife thinks I'm a troll also , says I spend too much time in my sewing cave {when I'm not out drop-testing.] But I have mastered the art of getting cypres cord through those insane washers. Inverted means 'upside down' If an object has a heavy end it tends to fall towards the heavy end. Add a tail as in kite tail or long bridle and you have stable inverted flight.

By that logic, other pilot chutes with heavy caps (Javelin, Reflex, Teardrop, Vector, etc.) would suffer a similar inversion problem.

They do In fact John Sherman reported this way back in 96 {Jump Shack Web site FAQ] I think someone else was drop testing back then.The Sky-hook is one answer to this. A plain old MA-1 will out perform many of our newer models. One thing to consider is where an un-inflated pilot chute is relative to deploying canopy"via bridle" in a low speed sequence.

Dear mystery guest,


The Reflex was drop tested in 1995 and passed all of it's certification, even pilot chutes that came off at weird angles worked just fine (BTW the Reflex was approved with or without the Catapult, it was actually double dropped (twice the amount of drops req)). Don't take "everything" off the Jump Shack FAQ as gospel, they have a vested intrest in showing their competitors in a less than flattering light. At least that's been my personal experience.

Going back to MA1 reserve pilot chutes is like throwing out 25 years of technilogical progress in reserve deployment design. The MA1 is a great "snagger" the only way to improve on it's "snagability' is to sew fish hooks all over it. That's not to say it's no good and doesn't work, it does!! It also has more snag points more than any modern incarnation of a reserve pilot chute. Too many people died due to hung up MA1's that's why things are the way they are today, it's called progress. Can't say I've heard of too many folk going in due to "inverted reserve pilot chutes", especially when compared to MA1 snags. Your thoughts?

Mick.


BTW my bio is posted for all to see, you know who I am may I have the same courtsiy?

I've often wondered how your mesh covered pilot chute was stuck to that pointy-nosed man on your patent. Fish hooks, what a gerat idea ! A 66 year record of untold thousands of lives saved by John Quilters pilotchute design and widespread use worldwide as we speak, I find awe inspiring. WE have managed to make his design more snag resistant and less costly to produce. But along with changes come new problems.

Hey I'm all for dialogue! Care to elaborate, mystery person? About the New "problems" I for one am curious.

Mick.

I see I'm still apparently not afforded the same courtisy of identification and experience about you as you are about me, pity. It makes it so much easier to to have an intelligent conversation when one knows who/ what (company or individual) one is communicating with.

The MA1 is used primarily in military back and QAC air crew systems. The newer air crew system being used by both the Air Force and the Navy no longer uses the MA1. That means even the Military, the largest user of the MA1, is moving away from the old design.

As far as "untold thousands of lives saved" I doubt if you could produce a list of 1000 lives saved by the MA1 outside of sport jumping.

I'm wondering which manufacturers / containers still use MA1's?
What is (for example) with the newer Tear Drop (SF/Viper for example)?

And how long did it take it before finding a piece of e-thread?

Alternately, you can angle-cut the bottom end of the Cypres loop - with a hot knife - and easily slip that pointy end through the holes in the Cypres washer.

The hard part was getting the singer off the other end.

I repacked a modern GQ pilot's rig last year. It wasn't just a plain old round but one with a lot of interesting features clearly derived from their military experience, and a rating of 280 lbs at 200 Knots. Despite all that, it used a lowly MA-1.

It seems that MA-1s have a lousy launch, lousy snag resistance, but if an MA-1 finally does find some clean air to catch, I guess it'll catch it very efficiently in any attitude.

That's a bit of thread drift, but it is interesting to what degree reserve PC weight, and how it is balanced, affects the time for parachute deployment. A low altitude BASE jumper wouldn't be thrilled to tie a one pound lead weight to their PC's cap! Yet skydivers don't start right at zero airspeed, and plenty of different designs get TSO'd. (TSO requirements as I recall are sloppy in that there's no maximum speed specified for the low speed case?)

Sounds like mystery guest is doing research on reserve deployment devices, I wonder if it's for a science project or or is he trying break someones patent? Or perhaps trying to get around existing road blocks to use new technology (read:Skyhook) for company/ indidual he represents? Does explain the annonimity angle. Enquiring minds want to know!! Identify yourself Sir! and let's have a meaningfull discussion on exactly what it is you want to know. We can probably help. Really.
