Semroc Micron

[blackbrandt]

Anyine noticed that the semroc micron with a conical nose cone looks a heck of a lot like a black brant? It is the 3.9 inch nose cone that I used.

Not really. The Black Brant has 3 fins and a tailcone. The fin's trailing edges are slightly sloped inward and the body tube needs to be longer.
I dont see much of a resemblance.




What does you last sentence mean????

I think it means he forgot to post a picture.

To be fair, there are many versions of the Black Brant, both 3 and 4 fin versions. While the more familiar version is posted above, here's a link to Black Brant V.

If you look at the parts list for the Micron it's definatly not a 3.9" cone:

BC-718
Ogive 0.715" 0.759" 1.8" 0.05 oz 1 oz.

No, when I threw that nose cone on the rocket, it looked oike a black brant

The Micron is a nifty little rocket. Looks good, flies great. It's also very basic. Change any one of it's three components and you're going to end up with a different looking rocket. I can see some similarity to the Black Brandt V in the link posted above. Apply a sounding rocket-like paint job and you have a reasonable facsimile. Having said all that, you could do the same thing to almost any 3-4 FNC and enjoy the same sort of result. I like that little rocket and FNC's in general.

Can we see a photo of what you've got?

I'm curious...I noticed the name (black brandt). I have this rocket in pdf, for a paper build. You wouldn't by chance be the designer? I noticed askrockets post #2 has a photo of it, but it's deffinantly not paper. This is a really nice rocket. If my current conversion project goes well this will be the next paper rocket I will convert to flight.

The one I have I converted to a stomp rocket or better an (air pressure launch rocket). I was experimenting with making it parachute recoverable.

On the paper version the fins aren't flat, they're thich in the middle and tapered on the leading and trailing edges, are they the same on the pro version?

[blackbrandt]

Whaddaya mean designer?

The (Centuri) Micron was basically an equivalent for the Astron Mark, itself a slightly modified version of the original Orville Carlisle Rock-A-Chute Mark II (using a balsa nose cone rather than the legendary Sweetie pencil sharpener) -- all these models are simply very very basic 3/4 FNC sport rockets and usually fly very well.

And yeah, several Black Brant models share the same basic profile -- it's a very effective rocket shape.

HaHaha...You are such a funny guy. No.

No, that's the 2.6in fiberglass one from Madcow Rocketry, a great HPR kit!

I must have missed something here, this joke went over my head. With paper models some one has to get this design into a computer program, unfold, flaten out, and convert to pdf for printing, thus some one has to design or should I say take something that already exist and turn it into a printable paper model.

[JStarStar]

The joke, I think, is that the Black Brant (the early versions at least) was designed 50 or so years ago, by Albert Fia at Bristol Aerospace in 1958,

http://en.wikipedia.org/wiki/Black_Brant_%28rocket%29

so to be accurate, Alibert Fia is the 'designer' of the Black Brant. Apologies to Albert if he is on the forum but I kinda doubt he is.

Most model rocket scale models are not "designed" as much as they are "adapted" -- since the idea is to produce a scale model of the full-size prototype, the challenge to the builder is to build a basic model rocket of an appropriate size and then dress it up in exterior trim, finish, etc etc to make it as accurate as possible.

While more and more models are making use of scaled wraps as are commonly found in paper modeling, many are crafted to scale accuracy without the use of exterior printing.

In addition the Semroc “Micron” doesn’t have a guy wearing a green polo shirt attached to it.



Is he payload? Or part of the recovery system?

The “Micron” is yet another Semroc kit sitting in my “Yet to build” box.
The Curse of Semroc is that they release kits at a rate 2.35 times faster than I can afford them. By 2035 I estimate that at this rate I will own 632 Semroc kits with another 12,878 that I want and can’t afford. Nor would I have the time to build them if I could afford them. Nor would I have a place to put them even if I could afford them and had the time to build them.

Hence the “Curse”.
