nf1nk Posted December 11, 2005 Share Posted December 11, 2005 It has been a while since I posted anything so I have the engine I am working on. (Some day I will get back to working on the bar scene just not today) This is a sort of fantasy rocket engine that will have moving flashing lights inside of it (thus the clear sections) I am trying to figure out how to rig a big crysta to the top of it as well as more hoses and some structure, but for now here it is in its unfinished un textred glory.

nf1nk Posted December 11, 2005 Author Share Posted December 11, 2005 The progress is fun Gosh. I prefer modeling to animating Next I need to work on making a nice titanium metal for most of the machine and also the exhaust that is the fun stuff.

Dhar Posted December 11, 2005 Share Posted December 11, 2005 I didn't realize there was a tube spiraling around that "bowl"? Being an HVAC engineer, I'd assume it's a defrost tube? Nice work BTW Quote Link to comment Share on other sites More sharing options...
Eric2575 Posted December 12, 2005 Share Posted December 12, 2005 Just curious about all the tubing. How are you doing that, sweep? What version of AM are you using? I am wondering about jumping from V.11.1 to V.12. Quote Link to comment Share on other sites More sharing options...
Zaryin Posted December 12, 2005 Share Posted December 12, 2005 To a guy who is not too good at mechanical modeling (me:)) it looks great. Quote Link to comment Share on other sites More sharing options...

I am wondering about jumping from V.11.1 to V.12." I am using version 11 (but am planning on buying the 2006 disk) The tubing is done with the dupilicator wizard and some hand positioning to clean it up. you would be surprized what you can do with it "I didn't realize there was a tube spiraling around that "bowl"? Being an HVAC engineer, I'd assume it's a defrost tube?" On real rocket engines there isn't actualy isn't a tube spirling around the bowl (on any real engine I have seen), for the most part there are instead lots of little tubes that go paralel to the rocket thrust with evenly spaced pressure manifolds to deal with the changing bell diameter. the cryogenic fuel is run along the outside of the bell and throat to keep thing from melting. I put the spiral around the outside because I wanted to, and I think it looks cool. This engine is a mix of real and fantasy I we have things like glass cooling fins on injectors (how is that for thermal conductivity ). since I am working on my ME degree I had interesting Thermo teacher who showed slides on rocket engines and during a lecture on entropy I scetched this on my note pad. I started work on the model after finals, and I realize I still don't get entropy... Quote Link to comment Share on other sites More sharing options...
nf1nk Posted December 16, 2005 Author Share Posted December 16, 2005 Here is an update on the engine I added a light to each of the cylinders and this upped the time to render by about 3. It is almost unaccaptable (almost 1.5 hr), I was thinking about removing the reflectivity from the metal since it was supposed to be dull metal and losing the refletion might speed up the render time Quote Link to comment Share on other sites More sharing options...
nf1nk Posted December 29, 2005 Author Share Posted December 29, 2005 Well as with all rocket engines there comes a time to fire em up and see how they look Quote Link to comment Share on other sites More sharing options...
arkaos Posted December 29, 2005 Share Posted December 29, 2005 Nice render! Seems like the flames should fill up the entire cone, but it looks really good. Can't wait to see an animation and the thing it will get attached to. Great work. Quote Link to comment Share on other sites More sharing options...
nf1nk Posted December 30, 2005 Author Share Posted December 30, 2005 Here is a short vidio of the engine running I wanted the exhaust to be blue ish but no matter how strong a light I stick inside the bell it doesn't seem to show, I guess I will have to turn Glow on Rocket.wmv Quote Link to comment Share on other sites More sharing options...
Eric2575 Posted December 30, 2005 Share Posted December 30, 2005 OOooooh, very nice! I can almost feel the heat. Really like the way you did that. Quote Link to comment Share on other sites More sharing options...
DanCBradbury Posted December 31, 2005 Share Posted December 31, 2005 That's some nice green fire you got there... Is it stylaized? or is it just the blue sky mixing with the yellow fire to make the outer flame green? Cool engine Quote Link to comment Share on other sites More sharing options...

Is it stylaized? or is it just the blue sky mixing with the yellow fire to make the outer flame green? Cool engine There are blue flames and yellow flames I guess when they mix you get green. Of course if you are running a copper liner at excessive temp you will get green highlights in your rocket plume. Strangly some of the newest rockets I have been reading about run copper liners, because of its high ductility and ability to conduct heat. I lke the effect so it stays Quote Link to comment Share on other sites More sharing options...
MMZ_TimeLord Posted December 31, 2005 Share Posted December 31, 2005 Excellent modeling! Can't wait to see the craft you put it on. Did you use particles for the flames? Quote Link to comment Share on other sites More sharing options...
nf1nk Posted January 2, 2006 Author Share Posted January 2, 2006 I have started to build the rocket (no nose cone or textures yet). The smoke is streaks of four different varieties and sizes. The rocket looks like it is going very fast but it is only a 4.7g launch (150 fps^2) Launch.wmv Quote Link to comment Share on other sites More sharing options...
Dhar Posted January 2, 2006 Share Posted January 2, 2006 Stupendous! That's some really great looking smoke. I'd like to know how you did it. Keep up the good work. Quote Link to comment Share on other sites More sharing options...
