Here’s the historical information on the nuclear Soyuz variants I have been able to find. My Russian is not great, in some cases the translation is awkward or not completely clear. Nick
The draft design of the rockets started on the basis of the Decree of June 30, 1958. Two bureaus, OKB-456, and OKB-670 were involved. The design chosen was based on direct heating of the working fluid, and it’s ejection through the nozzle. An open core reactor, in other words.
This was based on an image I found, taken from the cover of the March 1961 episode of the Magazine of Fantasy and Science Fiction.
A really unusual shape, making the whole thing look like a cross between a lightbulb and a thermos flask. I suspect it’s meant to be nuclear , which makes standing around the engine area somewhat adventurous.
I recently realised that I hadn’t blogged this design, which I did a few years ago. I realised this after seeing an image I had provided of it for a board game had been bodged onto a new background, and looked awful. So I figured I should get my version online ASAP!
This is a serious NASA design for a nuclear craft capable of reaching Mars.
Right, I think the modelling part is pretty much done here on the HOPE VASIMR. I’ve been busy adding nurnies and greebles, and tweaking surfaces, and it’s looking good to me.
As usual, click on the images for a larger version.
For those who missed the earlier instalments, HOPE stands for Human Outer Planet Exploration, and is a serious design for a manned expedition to Callisto, the outermost of the large moons of Jupiter. (Far enough away from Jupiter that the radiation won’t fry the astronauts!)
