Well first off I should say that my CAD college classes were done on AutoCAD 2005. I did not own a computer of my own at that time and thus I did not purchase the student version of the software but just used the system installed on the campus computer system. Now that I'm no longer in school...

Thanks for the clarification on the "flair stablization" and also on "fins". Basically I get a mold cut in a aerodynamically feisable design and then can adjust the lead casting alloy to whatever strength is necessary for proper structural integrity of the slug --- the weight will very...

Thanks for the clarification and math for question #2, minger. I've got the water tunnel partially built in the shop as of present. ----------------------------------------------------------------------------------- Now as to, jim mcnamara, you seem to be addressing question #3. For...

1~ Glad to have that one answered. 2~ Good input. Is my reasoning correct that "to simulate higher velocities with low velocity experimental apparatus" use water instead of air (thicker fluid) ? 3~ For assistence in the self education process in the form of pictures of cut open...

Okay, I've been working on designing a custom mold cut for a 410-gauge shotgun slug and need some help with the principle of "Drag Stabilization". Many shotguns are smooth bores and thus shotgun slugs in order to dependably fly straight must have a drag-stabilized design. They can not depend...

Thanks a million, sunday, that was exactly the information I needed. A little bit of algebra and everything was A-Okay -- just as you said it would be. :smile:

I'll see if the college library can't get them in on the inter-library loan program. It's really annoying how the college libraries don't have squat on anything gun related, unless of course it's anti-propaganda :mad: . I mean -- ballistic engineering is a legitimate intellectual field as...

Hello, I'm a college student in the last semester of my second year working towards my degree in Mechanical Engineering. I'm working on a project for my ODE (Math-222m) class involving the mathematical modeling of the internal ballistics of the common Spring/Air pellet rifle. I've got...
