First Rocket Design

**ghaspacer** · #1 03-07-2016, 03:20 PM

Many of you know that I like to build and design spacecraft and satellite paper models. I have several more that I have designed and I will release them soon.

While at the NASA website, I was reading articles on sounding rockets and
what they are used for. I like the way these rockets look and I thought that
one of these would become my first rocket design.

I choose the Terrier-Improved Malemute suborbital sounding rocket which was
launched on March 1, 2016 from NASA's Wallops Flight Facility.

There are several more sounding rocket variations and I plan one designing some more.

The biggest problem for me if the conics. If any of you have some good-easy to understand info on making conics for rockets, please let me know.

The first picture is the actual Terrier-Improved Malemute suborbital sounding rocket at launch, the others is the finished design work.
It's not 100% perfect, but I think it looks OK.

What you do think?

I plan on releasing this soon, now working on instructions.

WOW,,, That is a fantastic looking rocket you designed.
How big is it,,,
And are you going to offer it soon.
Best Regards,
Gary

Dear Ghaspacer:
Colorful Wonder if this could be made into a stomprocket or two stage Esties rocket. I like ones that are based on a real rocket.
Thanks,
Miles

The real one stands around 12 meters (36 feet) tall, depends on the payload. The model stands around 20 inches tall.

I plan on releasing it soon, working on instructions and final touches.

PayloadBay.com - Rocketry Tools

Returns a PDF you can work from. Nice job, BTW! Welcome to the party!

So about 1:21?

Also, where do you plan on releasing?

Well, to make a scale model, if you have all the measurements, (readily available with the rockets) It can be reduced to a simple calculation to get the scale measurements. So I put a excel spreadsheet together to do just that:

edit 100619: it has come to my attention that the use of the cone-o-matic with microsoft word is not completely described, so here are some additonal examples:

It allows for you to simply adjust scale and units, and still have all the numbers you need.

this one is also great for making cones, conic sections free software:

Downloads

Siatki 1.0.1

It is a very user-friendly program used to unfold 3D objects: cylinders, cones, and spheres. You can save results as BMP or DXF files or print directly from the screen. Most importantly, it is FREE.

I'm trying to set up a payment account on ecardmodels so I can sell some of
my models (I can the income).
There are several models I've designed that I have not released yet.
I'm afraid that releasing around 5 would be too much at one time.

Thank you every one for some input about the conic problems I have, My skills are minimal.

Now I'm working on the Black Brant XII sounding rocket and the nose cone is not as easy.
