Okay, I just hope we will get support for the "official" releases :) Well, it seems Blender has the same issue as Gmax: it would seem you have to use mirror modifer, not mirror from the mesh menu or your normals get inverted! :oh: Apparently it works OK with modifiers, I don't have time to...

2.56.1 r34985. It seems the script doesn't work with the latest release (2.57a). Do you mean Object -> Apply -> Visual Transform? It doesn't change anything. I tried that and it didn't help. Actually this is the same problem. If you use "mirror" at any stage when making your model it...

Despite my attempts I couldn't get all parts of my model showing up correctly in Orbiter. Thus I made a test: I created a linked duplicate of the standard cube, then mirrored the duplicate. I exported both to Orbiter mesh, and the results can be seen in the attached screenshot: the duplicate...

Thank you for taking the time to test it :) I'll have a look into my model, Blender seems to render it OK. I have no idea why it has gone that way, I haven't used lots of exotic modifiers or anything like that. The fuselage was originally a NURBS surface made from cross sections.

Sorry for late reply, I hadn't logged in for a while (been viewing only as guest). I made a basic turboramjet implementation based on those NASA equations. The biggest problem is that some parameters, such as IPR, are almost impossible to find for any jet engine. The code shouldn't be completely...

Please PM me your e-mail address.

First, thank you for your Blender exporter. However, there seems to be a problem in mesh export, probably with normals. The left main gear bay shows correctly whereas the right and nose gear bays seem to have their normals flipped (see attached images). There seem to be similar problems with...

Thanks to all for your input. There are equations also at http://www.grc.nasa.gov/WWW/K-12/airplane/thsum.html, main page http://www.grc.nasa.gov/WWW/K-12/airplane/shortp.html. The NASA site was one I had looked at myself too, and since everyone seems to recomend it that's probably the way...

Thanks for the reply. I'd guess I'm hoping to find something a bit more realistic, basically similar to Orbiter's sample ramjet implementation. So that given the engine's pressure ratio, BPR, maximum thrust, TET etc., and altitude, fuel flow, air flow etc. I could calculate the thrust it...

I'm in the process of creating my first Orbiter add-on, one that is based on a real design that has two turbofan jet engines as a part of the propulsion system. I know the Orbiter SDK supports rocket and ramjet engines (ramjet code in DeltaGlider), but are there any add-ons or other places that...
