After chatting to Matt, co-author of “N1 for the Moon and Mars“, I decided to dig out the meshes I did for that, and come up with some new renders. It was a mad dash to get it all out in time for publication, and I didn’t have time to explore all the options.
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”
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:
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.
I was recently given some postage stamps, mainly covering the achievements of the Soviet Union during the early days of the Space Age.
It occurred to me that they might be of interest to those who read this blog. After all, there can’t me much astronomical art that is more widely seen. And probably no other space art that people get to lick…
Identifying N-1 variants. I mentioned this briefly in an earlier post, which featured some images I stitched together from video, but here it is in a bit more depth.
You are generally trying to distinguish between 5 different N-1 variants in photographs, the four that flew, and the weight model. This is most easily done via the colours, though there are several other differences.
This post is not about ALL the differences between the variants, just about how to tell which rocket is which.
N1-3L, the first flight.
This is easy to identify, as it is the only one with entirely grey first and second stages. The third stage is half white, with the white part facing upwards on the transporter, which is the side away from the gantry once the rocket has been erected. It was transported to the pad in winter, and there are photos of it with snow on.
Note that there was no green on any of the N-1 variants! This is a widely held misconception, as many museums show it as green, (including the London science museum, and many Russian museums too). Olive green was only used to camouflage missiles, (and green would make lousy camouflage in Baikonur at the best of times). This error has spread to the point where photographs have been tinted to make them look green). And sometimes it was just poor quality film stock.
The NK-33 engines were originally built for the Soviet Moon Rocket, the N-1. (Under the designation of NK-15, and NK-15V for the high altitude version). This design was a direct result of a blazing row between the Chief Designer, (Sergey Korolev), and the best rocket engine designer, Valentin Glushko. Glushko wanted to use propellants which Korolov considered far too dangerous. So Korolev turned to Nikolai Kuznetsov, who up until that point had only designed engines for jet aircraft. Large rocket engines are notoriously difficult to design, due to combustion instability, so they were pretty much forced into a large number of smaller engines.
Many consider this a key reason for the failure of the N-1 program.
