Seeing a little slowness in posting of new designs, I thought I would post one! Idea came from some excess balsa pieces from a kit I built a while ago..Looking at the 'scrap' it struck me they actually look like fins..lol..Off to play with my new toy RockSim!

It is an 18mm based rocket..Named Strike Six as it kind of resemble the Bullpup and has 6 fins..Cute right? Looks neat on the screen..will see how it looks when I build it!

Length: 14.75"
Diameter: 0.976"
Fin Span: 3.351"
Weight: 2.6672 oz


B4-4...406'....DV 5.63 ft/sec....1/8"x48" launch rod
B6-4...419'....DV 11.4 ft/sec...1/8"x48" launch rod
C10-7...1236'...DV 3.62 ft/sec..1/8"x48" launch rod
D3-7...2514'...DV 13.81 ft/sec...1/8"x48" launch rod

Aim high, fly straight!

Since we haven't closed this thread yet, I'll add a new design here tonight...

I have this not-so-big backyard, about 200' x 175', and I thought about what size rocket I could safely fly here. I figured it needed to be streamer recovery to reduce drift, and needed to be capable of flying on about a 1/2A with a decent Dv. The thought occurred to me that most designs would use a small-diameter body tube, to maximize the altitude, and that would be detrimental to my purpose. So, I went the other way...

This design uses Series 13 components, and can still reach over 265' with a Dv of 3 on an A10-3. The performance on a 1/2A3-2 is just right, at 101' with a 7+ Dv. Both motors get off the pad with (guide rod) inches to spare.

Length: 16.60"
Diameter: 1.34" (ST-13)
Fin Span: 4.7"
Weight: 1.1 oz

1/2 A3-2T......101.5'......Dv 7 FPS......24"
A10-3T.........265'........Dv 3 FPS......20"

Enjoy!

Since Buzz has closed the "Scrounged 2006" thread, please focus your attention on this-here post from Way Last Year...

Recently, I've been making my RockSim nose cones look A Lot More Like the Real Thing, hence this updated version of my "Tryton" design.


Thanks, and cheers,

This design was made for one thing and that is altitude. With a C6-7 should get above 2000 feet. This small of a rocket however would never been seen at that altitude so I used a 30 inch length of 3 inch wide yellow caution ribbon for the streamer to help the visibility problem. I avoided using the B4's as the Dv's just don't work well.

Enjoy and Thanks Again, JP

PS. I have already started the 12 Days of Christmas file for 2007. Its about half full of some really good design but you will just have to "Wait Until Christmas" JP.

I have come to like this vintage look in a design with a paper transition housing the motor mount that extends past the main body tube. This look however is bad for the static margin in shorter designs. I fixed the problem with larger and longer fins that extend past the motor mount itself. I also felt that the fin root needed added strength so I added two 1/8 inch balsa stripes to each fin root edge for reinforcement.

Enjoy and Thanks Again, JP

Here is a new design as far as model rocketry goes. Found this a while back searching the net. Looks like the original is missing its name and specs and is now concidered a "Mystery Missile". I did my best to keep this design somewhat to scale, but this particular design proved to be a challenge.

Enjoy and Thanks Again, JP

Here is another design I have had on hold for a while called Regulas Probe. I like the looks of this design but it does lack preformance with the large forward fins set. I guess I have a tendance in designing a larger upper body section for easier and quicker parachute loading. I have always disliked trying to put a 12 inch parachute in a 3/4 inch tube . Besides the faster I can reload the quicker I can launch it .

Enjoy and Thanks Aagin, JP

Just a heads-up to all BARCLONE contributors: We have now crossed 31,495 on the hit counter at the BARCLONE website. Even without a recent update (which is coming, Real Soon Now, promise...), there are a lot of good folks looking for new designs to build. I think our past work is still better than some of the newer commercial kits that have come out in the same time frame. Are they ever going to be surprised at what the new website will have to show!

Also, a reminder concerning postings here. On January 1, 2008, this thread will be locked and will not be accepting any further messages. All new messages concerning BARCLONE designs and commentaries need to be posted to the "BARCLONE Designer's Studio" thread. The new thread is already opened for submissions.

Command Confirmed .

Its getting real close to the 2nd Annual 12 Days Before Christmas . We will see if time allows me to pull it off again this year.
As far as any design I have posted, post them all on Barclone. No time for any of that kitting nonsence. Besides I'm just too lazy .

PS. Can the Barclone Design Studio be made "Sticky" after the first of the year??
