dwwolf you don't like your crewmen crispy? Joking aside; It's more effective to use separate radiation shields, since they are not impacted by the temperatures that NTRs operate at. So you can use materials like lithium-6. Hope this was of help.

Surprise Christmas update!- Added a clearer comparison chart, allowing for better illustration of the ideal angle for a nozzle. (See Further extrapolation segment)
- Fixed my broken math within the NTR synopsis fuel comparison.
Small changes may follow.That's all until after new years. Merry Christmas and a happy new year!

Just so everyone is aware; I am not going to have time to do any great deal of work improving and adding to this thread over christmas and new year. In the meantime I will be lurking around. Happy holidays people!

Dhan jasonvance Very interesting stuff indeed, I'll have to toy with this at once!

dragonkid11 Do you want an osmium war, because thats how you get an osmium war! The Astronomer You were making a tanker to compete with newageofpower you say? Gee I didnt know there was so much going on behind the scenes here.

The Astronomer I know, and I love watching it; Not even four hours since the update and peeps already going ham!

What about using drop tanks as a means of delivering drones and missiles to target intercepts without using any on board delta-v?

amimai Thanks for mentioning that; Unfortunately i've only dabbled with actual Dv effects for a short while, but i've been planning to do something along those lines. From what I have seen though, in the instances which I have observed, more exhaust velocity is more desirable despite mass increases; The returns for this tail off quickly however, and I have not put any time into mapping the data. I'll certainly move it up on my to do list for the future though!

Updated OP with my latest work of horror! Appreciate any feedback people, so feel free to criticise.

newageofpower One day i'm sure I will have a crack at analysing that for you! For the time being however; My working hypothesis fell flat on the floor, my data is inadequate and worst of all i'm out of coffee! I've got another theory that has stood upto more scrutiny thus far, and i'm starting to build a working model of design around it. It's fair to say though, i'm behind schedule.

Stay tuned people, i've been working on CDE engine nozzle theory and will be posting my findings here shortly. Within a day or two. It's going to take a while to collect all the data; But if my working theory is correct, nozzle design is going to become alot less guess work and more scientific than ever before! My end goal is to turn this thread into a go to place for engine design; So expect alot of editing and reworking on the OP.

The Astronomer & newageofpower Thank you for making me aware of this. acetylcholine Well you're certainly right about being able to shave off injector weight; But making it smaller would be the incorrect way of doing things! Here is what can be done to greatly improve TMR:- Bumping up the injector radius to 1.2m, decreasing its RPM to 20 and switching to lithium. This will save you a huge amount of weight while maintaining coolant flow of 2.07t/s. - Setting gimbal inner radius to 1.7m to compensate and changing to potassium momentum wheels running at 900RPM. This is all assuming you have a reactor core height of 4.8cm, since you didn't show that in your picture. You can also loose 1kg of control rod mass! Doing this will leave you with savings of 138kg and 100c per engine; And in case I missed anything here is what changes I made. Hope this helps!

acetylcholine Your link takes me to this thread! The Astronomer I was under the impression it was rare, but i'm not well read on alot of stuff so I don't want to debate on what I don't know!
