SEMROC Body Tube Database File for RockSim 9
 
2 Attachment(s)
Everyone,

Over the last few days, an attempt has been made to create a complete set of component database files (CSV files) for SEMROC items. Small sections of this work has already been posted, but as we check our work, we're finding measurement precision errors in the entries. The problem is easy to correct, but it is equally easy to slip through the cracks.

The new file, attached below, is the full set of body tubes as offered on the SEMROC website. It is being put here for review, so wait before we announce an "all clear" to install it.

Addendum: OK, so much for my ability to pick the right file to upload. I've attached the Semroc BTDATA.CSV file below.

I hadn't run across any errors in the previously posted files yet but I've only used the components in two designs so far that I'm updating for BARCLONE. I kept a complete back up of my v9 install and it's easy enough to load the original component files back in. That's one thing I really like about RockSim is the ease in moving data in and out of the databases by editing the csv files.

Craig, a big thanks to you and Bill for you efforts with producing these component files!

:)

Correction to earlier post
 
The BTDATA file is now attached to my earlier post, along with the NCDATA file. These contain only those components from the Semroc website which can be drawn with the 'wizards'. There are almost as many that cannot be drawn that way, and for those, we'll have to generate RKT files later.

Here are the BHDATA (bulkhead) and TCDATA (tube coupler) data files that have been checked and verified for decimal precision.

Craig - please give these the once over and make sure the numeric precision looks ok. I used the technique you suggested in Microsoft Excel to ensure 3 decimal precision on all numeric fields.

Transition file may take a day or so to complete. I actually took a break from parts and was working on my first 2009 design. I hope to post both by the weekend.

Thanks for combining the nose cone and body tube parts into master files!

... Bill

Bill,

The data looks OK. The Estes Classic designs seem to have the proper 3-digit precision. I've already imported them into the program. Unless something breaks :eek: I'd say use them.

New Design -- 2009 Test Rocket
 
3 Attachment(s)
Here's my first for 2009. This is a simple 4FNC using the components from our new database files. I think the files are safe, now, after some teething trouble. This rocket is similar to our "Thunder" series from a few years ago, but uses a 13mm motor for power.

Length: 18.925"
Diameter: 0.908" (ST-8)
Fin Span: 3.908"
Weight: 1.001 oz


1/2 A3-2T......124'......Dv 17 FPS......36" x 1/8" rod
A10-3T.........341'......Dv 21 FPS......36" x 1/8" rod
A3-4T..........350'......Dv 9 FPS.......36" x 1/8" rod


Enjoy!

First batch of Transitions and Tail Cones
 
1 Attachment(s)
This first file covers the Series 085 and Series 10 Tail Cones, and the list of standard transitions from the original file. Unless you just want to get a batch of Semroc items into RockSim, hold off on installing this file. Wait until a full set of parts is posted.

Bill, one change from the other files you will need to make is the precision of one column. The "Rear OD" column needs to be set at 4-digit precision if you try creating the reversed nose cones. The OD value needs to be set at 0.0001". This value gives RockSim something to chew on, while not being large enough to be noticed visually.
