2012 RAMV-1, Mach one attempt


It's been a while now, hasn't it! I've been diligently working my tail off at my actual job, making enough money to fund some of the projects that I'd like to jump into in the next year.
That being said, I think I've come up with enough funding to start my mach 1 rocket plane project.                  (finally)

I've started to make progress with the RAMV-1 (Ryan Archer Mach Vehicle-1 (for mach one)) design,
here are a few details:


(Black and yellow colors only to designate different aircraft parts)

I've chosen the basic general dimensions and design goals:
RAMV-1 Specifications
Length: 38"

Width: 17"
Height: 5"
Weight: 50 ounces (loaded)


Aerotech 38/720 Rocket Engine

Engine Specifications:
Engine Manufacturer: Aerotech-Rocketry
Engine Diameter: 38mm
Aerotech 38/720 Rocket Engine
Total Impulse(newton/second): 723Ns
Average Thrust (In newtons): 515N
Burn Time: 1.4 seconds
Ready to launch Mass: 23.1 ounces
Burnt Mass: 10.3 ounces

Oh, you may also be interested in this thrust curve graph:
(The motor used is the J500G)

The first thing I did after deciding upon the 38/720 rocket engine, was to draw it up in Solidworks.
I used this nifty little engineering drawing provided by Aerotech:

Aerotech-Rocketry RMS 38/720

Then, all of a sudden this appeared:

I have a lot of things left to draw and engineer. All of the stuff in this first post is subject to change and most likely will. Think of this as a rough first draft, something that illustrates my thoughts, but is in no way a legitimate design just yet. Have a look at my list of things to do for this project:

list of things to do for the RAMV-1 (in no certain time frame) includes (but is not limited to):

1. Finalize design and make engineering drawings of the parts.

2. Carve a solid wood plug of the airframe, Paint the plug and polish to a mirror finish.

3. Take a heavy 2 piece fiberglass mold of the part, seperated top and bottom.

4. Profit

I think that's far enough ahead for now, we'll have to see how it all plays out....Time will tell :D
I go back to work on monday after being gone for nearly 2 and a half weeks, so my time will be limited for a while, but I will work on the RAMV-1 when I can.
to end this blog post, I shall include several screenshots of the RAMV-1 Solidworks model:
