PC Drag Table

[imported_Mac]

I used to have an XLspreadsheet I took from the net on the drag of various PC sizes and air speeds - anyone recollect where this may have been from or does someone have a copy they could email me?

About the end of 2002 I gave Mick my Excel table on Freefall and P.C. drag forces for publishing on the BASE Board for anyone to see/consult it.
You can find it at http://www.basejumping.net/cms/deployment.shtml: the table is under the article "Freefall + P.C. drag force" and click on the "Download/View file" button to see it.
Remember to read carefully the warnings/tips in my article, and moreover, remember it is NOT the truth but just a table, that is a good representation of reality provided any factor is very close to "perfection", but when something goes wrong it is and it remains a "table"... ...when a P.C. is NOT inflated, its pulling force is 0, no matter which the airspeed is ;-)

Stay safe out there

Hi Guys,

Does anyone have a copy of a "pilot chute drag/force" table that was floating around a couple of years back, I think Andrea Checchia developed it?

Cheers,
Mike.

It used to be on the BLiNC server, maybe Mick can dig it out?? http://blincmagazine.com/forum/f59/t19817 Referencing: http://www.basejumping.net/cms/deployment.shtml

Here is another table from Nitro Rigging:

This is the corrected one:

Do you still have the XLS file on the server?

[Greenmachine]

Do you still need a copy of the Excel spreadsheet?
I am pretty sure I have a copy on my home computer.

Can you please get me a copy so I can post it in the Knowledge BASE ?

Hi Mick,
I have it but cannot see how to upload it.
(invalid file)
Take care,
space

[mknutson]

I uploaded it. But can anyone convert this to PDF for me?

[Mac]

I thought the idea of the original file was that it was XLS so you could put in your own variables? Or do I not remember the file correctly? I certainly made some changes when I first DL'd it, mainly getting rid of the Italian blurb, but I thought you could put your own weight etc into the calcs? This functionality will be then lost in PDF formating it.

Hi Guys,

I tried to download it, but it's not an .XLS file :(
Any ideas?

Cheers,
Mike.

[mknutson]

Does it say it is not recognized? I was using a newer version of Win Excel.... maybe I need to use an earlier version...?

[finflyer]

I also have it in my computer, if you need it then please ask it dropping a mail to vtoropainen@gmail.com , I don't come here too often.
