Vented PC's

[flydive 0]

As a very new guy in the sport (less than 25 jumps), can somebody explain what a VENTED pilot-chute is and what it buys you versus a non-vented PC? Also, what's this I hear about directions of mesh, etc...
Probably needs to be a new thread...?

a zp(i never saw them in F-111 but i could be wrong) pc whith a hole in the top.in that hole theres mesh like the buttom of the pc.

A vented pc should be more stabel,which means it should help keeping an onheadding to the canopy.

other can sure describe this better than me

Vented PC's have a mesh vent on the topskin. Different vent configurations have been tried (my personal favorite is the configuration currently used by Morpheus). The idea is that air is vented out the top, instead of the sides, so that the PC is more stable. Orbiting PC's can cause off headings, by switching extraction directions during deployment.

Do you have 25 BASE jumps, or 25 skydives? I hope it is skydives.

[nicrussell 0]

I believe he is talking about BASE jumps. His profile lists that has been in sport parachuting for 9 years with about 800 airplane jumps.

I was wondering that - surely this is the sort of thing you should know about before you start huckin your carcass off stuff relying on equipment being made correctly?

or am I being too harsh?

Here is a pic of my morpheus tech vented pc. You can see the mesh venting around the black cap at the apex. I am not sure but I believe all other vented pc's by other companies are completely vented (meaning that the entire apex is vented without a cap).

That's pretty much what the Bounce Proof pilot chute vents look like. Ray has been venting pilot chutes for years before they became mainstream.

...or am I being too harsh?

When I first started asking questions, some people were dicks and others were generous with their replies or at least informative.

No one starts this game knowing alot about alot. At this stage of the game, I still know very little. I have vowed to, whenever possible, try and be helpful to those who ask rather than judge them by a simple question.

Hope that helps.
....

I'm curious to see the construction methods used on the Morpheus vented pilot chute since I've only seen one in pictures. I have several AV pilot chutes made by Asylum and they work rather well but have nothing to compare to.

My grammar sometimes resembles that of magnetic refrigerator poetry... Ghetto

Agreed. Someone can either ask a question and get help, or keep jumping and not gain knowledge.

Ideally, a new jumper will hang out with a more experienced BASE jumper who can't stop talking about BASE gear and techniques.

I talk and think about BASE all day. If you want to share ideas, come hang out with me.

That's a reasonable question from a new BASE jumper.
In the beginning you rely on mentors and manufacturer QC.
Sometimes you rely on the next clown in line, as if he knows anything.
Believe me, there are some hot-shots who don't even know what bias is....
Eventually, we all realize we need to be our own rigger,
then the little details become important.

Edited to add:
Vented PC's are not the end-all in PC mfg.
An assymetrically loaded vented PC could oscilate.
A poorly constructed PC of any type could be deadly.
If everything is perfect, you could still have a bad day.
The only way to be sure you will not get hurt on a BASE jump: don't do it.

In my opinion, assymetric attachment will overcome venting. I think that venting is only going to matter when everything else is done correctly (i.e. PC is attached symmetrically, constructed correctly, etc.).

by the way are there F-111 vented pcs out there? im thinking of the smaller range to slider up which i ofcourse dont know sh#t about

Tom you for got the pic

Maybe (we) I was too harsh whit that comment, but if someone with 25 base jumps don't know what is vented PC, he should be VERY scare, and maybe he should consider changing base crew or mentor.

[BASE813 0]

that may have been harsh, and yes I know that I am still learning and I dont really know shit, and that asking questions is a good thing, but surely there is something wrong with someone who is hucking themselves off objects (with 25 jumps its not unheard to not have a mentor or to be going out soloing) and not to have a basic understanding of equipment available to you (I agree that perhaps the bias thing is not something that a great deal of people are fully knowledgable about).

Sorry if my tone seemed harsh and I appeared to be one of those "dicks" but shouldnt one want to know as much as possible before they start experimenting with Low Alitiude Parachute Deployment Science?

Sorry for being a dick

just dont let it happen again,or ill show you which kind of dick you are(intern joke about some video i will keep to the day i can sell it to mac for the right amount of mony,nahh fuck that having it using it against you all the time is much more fun than mony)

Now claim your right:

I some how agree that a person whith 25 jumps should have the knowlegde of this kind of gear,then i look back and onto myself,i guess i wasnt better at that pointHell i still sucks but whos give a Sh#t

Ahhh... this forum never gets dull, I love it! It's like pushing people's buttons just to be vicious and get a laugh! In my case, ask 2 simple questions and get 17 vehement responses... only a couple of which attempted to answer my questions, which I sincerely appreciate.

Anyhooooo... now that I've been soundly chastised for not being an expert on all facets of the sport at the scant number of 25 basejumps, I'd like to ask again... is my brand-new (ok...18 jumps) non-vented PC unsafe? Am I setting myself up for something detrimental when statistics finally kick in?

Second question: What is bias? And what does it mean to me as a low-time basejumper?

Please don't stop the attitude, hollering and jeering... I really do get a kick out of it. Just try and teach me something at the end of your post. That's all!

Also, why are vented PC's only offered up to a 42 on this website? Why not a 46?

non vented pcs has been used for a long time whith ok results. I think your in no more danger than the rest of us.
That said i didnt belived it and my only unvented pc as today is a 48´and a old 45´

Why Morpheus dont make em? hmm i dunno if the do or not but try mail them theyre really kind people,just dont say you spoke to Faber or they will laugh all over

This is just what I remember from a couple of years ago. So I may not remember it correctly. Morph. was doing some testing on the vented pc's and I think that they felt the venting didn't have as much benifit when you started getting into that size pc (short delays). Like Faber mentions though... you should email them/call them. Then try to post the answer here. Or have them pop in and answer themselves.

I didn't know what a vented canopy is for a long time, there flame me too. how goes the journey for jumps out there man? lucrative I hope. If you ever get to Denver, remember, fun to be had.

Hey.....Vented Mesh-Apex on your Pilot-chute sure beats
burning Holes in the top with Lit Cigarettes.

* No ...as long as you are using proper size in relation to your delay of free-fall and it is properly constructed.
.....................................................

Also, why are vented PC's only offered up to a 42 on this website? Why not a 46?

* Your delay being very short it is more likely will be affected More by other things like:
body positioning and out side interference like wind etc.

* A 46 or 48 is not hanging like a Anchor long enough to start oscillating.
You pitch it out / It's ripping your canopy out of container.
If it is Not... You have a Container Lock or a Severe PC Hesitation.
........................................................................


What is bias? And what does it mean to me as a low-time basejumper?

* Are we talking about the way the Taping is sewn on the Rip-stop material ?
The cross hatching design of the reinforcement (those little squares) ?
or
* Are we talking about the Mesh material on a PC.. ? Which way it is turned because
it has a directional stretch to it to.
Depending on which way it is turned. On the Square / or On the Bias. ?
Taping on the mesh is what gives it an even or balanced shape.

* Those little squares of reinforcement in the Rip-stop Nylon.
If you turn them 45 deg. from square to diamond.
Its changing them from being square to the Bias.
Tapering done on the Bias is much stronger than being sewn on the square.

* Your attitude of BASE Jumpers on this Forum is Bias.
Thinking that we are all Ass-Holes... (most are not)
Some of us actually take great Pride in being an Ass-Hole when we Post hear.
