Wow! I didn't think it was that long ago! You actually have saved emails from 2002 ??? :confused:

I sent you a PM. CD is going in mail tomorrow morning! It includes latest version of both released and development versions of the Open Office software.

Enjoy,

... Bill

34 fin patterns in the attached file. EnerJet, FSI and LOC Precision as well as a few custom fin patterns from a few BARCLONE submissions. I need to dig out others from my back up but this is just what I transferred back into v9 after my initial install. There are a few rare and OOP fin sets included from SSRS, Blackhawk R&D and Public Enemy Rockets in the file as well.

These LOC Precision fin sets I posted here are from kits not included with the data RockSim v9 installs. I built the actual kits so these LOC Precision files are not estimations but entered with data that I obtained from the kit fins that shipped with the kits.

I think the file is ok but Craig may want to give it a quick once over just to be sure before you import the CSV file .....

:)

File looks good...
 

Steve, thanks for the additional fin patterns. They appear to be functional. I had a little trouble importing them, probably my own fault, but I worked around the problem and they're running fine.

Everyone, go ahead and use them!

Batch #1...
 

OK, here's my first contributions to the fin database project. I've collected some of the better models beginning with "A". I'll try to post more a few at a time.

This batch includes the Antares and the Arcturas...

Designs beginning with "B"...
 

Here's the next fin pattern installment.

Is it true nobody knows here what an Enerjet 36 booster is?

Is there a TEXT based list of needed and wanted fin patterns?

Jerry

I am a bigger geek than you are.

This thread has sorta languished for the last few weeks... :o

We don't have a list of needed fin plans, except to say those designs on the BARCLONE design list which have not yet been added into the fin database. I have not looked fully through the RKT files Apogee provides with the program, so I don't know if the EJ36 is there, but once someone produces a RKT file using it, they're welcome post the CSV entry here.

If you happen to have an original pattern for the EJ36, we'd appreciate having it posted. We can also do the plot, if you don't already have RockSim running.

BTW: At 245 lbs, I'm not exactly a small geek... :D

This was a Nike-Ram lower section as booster and a Nike-Ram as upper stage. It used an "instajet igniter" in the booster and Enerjet fuse upper stage, initated by a Sure-Shot or an AG-1B flashbulb.

It was intended for fairly heavy payloads.

I just looked again at the database file I'm using. Unless there is a difference in the models, Steve Naquin posted a CFDATA.CSV file earlier that has the Nike-Ram fin pattern included. All you have to do is place this file into the DataImport folder of RockSim 9 before you start the program, and it will import (append) the contents to the active database.

I found my copy of "The InstaJet" Development of an instant EnerJet igniter article that Taras sent me some time back. I have most of the data entered into RockSim from ages ago based on dimension given in the article and other dimensions from an old post on here from AL.

If there is interest, I'll tweak up the file and post to BARCLONE. Last year I purchased all the parts to build a Sonic 36 from Semroc, except for the fins (I planned to cut those myself).

Some of the things Jerry posted have started to click and make sense about the concept of a booster for the Nike-Ram. I didn't realize the Nike-Ram was the basis for the Sonic 36 design until I located and looked at the line drawing in the article. The dimensions differ a little as the booster is a little shorter and the fins just slightly larger than the Nike-Ram.

Thanks Jerry for the info you posted in the other thread ..... now it makes sense.
