RN-2, the Nuclear R7, The Historical Reference Information

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.

OKB-456 is now known as NPO Energomash, and at the time was run by the brilliant but prickley rocket engine designer, V P Glushko. OKB-670 was run by M M Bondariuk. Bondariuk had been working on nuclear ammonia rockets since 1954. Continue reading “RN-2, the Nuclear R7, The Historical Reference Information”

Nuclear Soyuz – ЖРД / ЯРД, an unflown design

Not that long ago I got an excellent book by Alexander Schliadinski, who provided the core information for “N-1 for the Moon and Mars“.

New reference information on the UR700

Quick introduction. I have recently been working on Chelomei’s UR-700, his Universal Rocket System, based on a design unit that eventually became the Proton. It was intended to replace the N-1 as the vehicle to take the Soviet Union to the moon.

Thanks to a comment left on these forums, I was refered to a website which had photos of something I never knew was built – a large scale model of the UR700, for vibration testing! It was made at 1/10th scale.

Before we get started, here’s a render I did, which shows you the overall configuration. I think this will help you understand the layout.

The rubber hoses were used to fill it with water, for when it was suspended, and given the vibration tests. It was also suggested that alcohol would be the correct liquid to use, instead of water. Continue reading “New reference information on the UR700”

Progress with the UR-700 moon rocket

Right! The launch state version is coming together rather nicely. There are some deails still to be done, and the surfaces need some work, but I’m begining to see how the finished one will look.

It’s not going to be super accurate, but I was really pleased that my Russian friends like it.

The colours are arbitrary to a degree, but I think I have a sound justification for them.

Here’s an exploded view, to show all the elements:

Chelomei’s UR-700

Back to the space hardware, and my latest major project.

Project History

This is Chelomei’s UR-700, intended as a universal rocket, (in various configurations), and a competitor to the N-1.

This was a real monster, and basically consisted of a cluster of no less than nine Proton rockets. This was done so they could be comprehensively tested at the factory near Moscow, and shipped on trains to Baikonur for assembly. The Proton started as the UR-500, an element of this design. The engines were built and tested, but there was no appetite to start again, cancelling the N-1.

Next project – Phil Bono’s Hyperion

Next up, another classic design from the fertile mind of Phil Bono, the Hyperion.

This is a large single stage to orbit (SSTO) design, which can launch via a rocket sled, (should there be a convenient nearby 1 mile high mountain, anyway).

NASA PRANDTL Flying Wing – finished renders

Some finished renders of the flying wing design. See previous posts for the work in progress, and sample reference images.

The sky was the most difficult part here. I was compositing onto panoramic photos, and had to make my own sky. I really liked the dark greyish green, but it’s not very realistic.

Krafft Ehrike – 1958 Space Station design

This is a design by Kraft Ehrike, which appeared in “Life” magazine in 1958. From what I understand, the idea was to use the kind of cylindrical hulls and spherical ended tanks from upper rocket stages as basic units of contruction.

ke-tube-station0500xEhrike worked with Wernher von Braun at Peenemunde on the V2 rocket program, and continued to work with WvB after they had moved to the USA.

Delta II rocket complete!

Right, I may twiddle and tweak a bit, but I am calling this one done.

mars-pathfinder-rocketI’ve done various configurations, but (at least so far), I am only doing one fully textured version. And that’s the Mars Pathfinder version above!

The others use generic textures, rather than depict one specific mission.

Here are a couple of perspective free sets:
