An Open Source model rocket simulator.
For 90% of what I want to do in rocket simulation, this does it. A fine piece of work! The main shortcomings are lack of a few features I would like to see. I'm glad this release is starting to address tube fins. I'd also like to see it allow fins on boattails (V-2 anyone?). I'd like it to support (and print patterns for) cluster mount centering rings. I'd like strap-on boosters. I'd like it to allow more generality in rocket design — compound fins, for example. In fact what I'd really like is to be able to take almost any rocket design out there (Shrox, I'm looking at you) or in my head and draw up the design in OR, even if it gives me warnings that certain design features will not be simulated correctly. (Or, perhaps better yet, a separate rocket design application, allowing more generality than OR, but interoperable with OR so that it can import OR designs while OR can import its designs provided they meet OR's simulation constraints.) I ding OR a little bit on the support aspect because of the lack of OR presence on YORF. Some of us are just a little too fed up with TRF to spend time there. At minimum, new release announcements on YORF would be a good step.
