I'm researching a scale project. I've always loved the rockets with multiple external boosters and found that the Delta II 7925 was used to put MER A - Spirit - on Mars. Looking to make a large ModRoc to small Level 1 size model - about 1/36.
I found a lot of info at Boeing and NASA, but have been unable to find nice (even decent) artwork pictures for the scale markings. I also have some questions about getting the right sized tubes for the boosters. I have some ideas and sources, but would like to see what those who have been there and done that have.
So....
1) Anybody have links to MER A artwork and/or dimensions of the right Delta II? Yes, I've searched the web several hours and found _some_ of what I need.2) How have you solved the problem of scale tubes? Once I pick the main body, I have a fixed scale and will need to make the boosters a dimension I probably cannot get commercially.
Stability and performance questions also arise, but those are probably answered by "just get RockSim".
Any help is appreciated.
BTW, the GEM-40 strap on boosters (this model had 9) have an average thrust of 499 kN for 63 seconds, making them 75% X motors. JIC you were wondering.
