Luna 7 or SpaceX in Russian

Easy rocket as the key to success h4> In the beginning a little bit about the company. "Lin Industrial" - a small team of engineers and scientists who work on various projects of civil and dual-purpose. The news section of the website tells us that the company "Lin Industrial" received certificate of the participant of the project "Skolkovo". There's also managed to learn that the "Skolkovo" command from the "Lin Industrial" promotes its development in terms of light and ultralight boosters: Adler and Aldan . In my opinion, this is a very sensible approach, as we recall a well-known Elon Musk just started with the development of light booster Falcon-1 . But on these projects as some other times, as I am most interested in site section "Our long-term projects" with a proposal for the development of manned space flight - "The Moon Seven".

Why actually seven? H4> As you know, at the moment people landed on our natural satellite six times during the Apollo missions. Lin Industrial Company offers to do it for the seventh time, so much so that to stay there a long time. Naturally Roscosmos has already announced plans to colonize the moon, but Lin Industrial confident that with the terms of which are incorporated in the program, that that Russia will carry out the seventh landing is not out of the question, China comes on the heels , and the Americans no one bothers to once again adjust the plans, the benefit of the establishment of the carrier rocket SLS and Orion spacecraft reached the finish line. In order not to lose the initiative in the field of colonization of the Moon, in Lin Industrial project offering the most of the existing (or available in the near future) technical solutions such as:

• Booster Ангара-А5;
• spacecraft Союз;
• Upper Stage Фрегат;
• Upper Stage KVTK .
  From left to right (or bottom-up, if you like): third stage A5 KVTK, Frigate and the Union (or rather, what's left of it). As with such a limited set of hardware will be able to carry two astronauts landing on the moon? And this is as much as the Americans were able to land on the moon using a monster like the Saturn 5.
  
  

  Not a single Kondratyuk h4> I already wrote that scheme Кондратюка allows you to deliver on the lunar surface greater load than the direct flight, but even so, to landing on the moon to the Americans needed a rocket carrying capacity of 140 tons. What to do if such a missile we do not? Roscosmos solves the problem head-on, if the missile is not present, it to build. It was at this point, according to the guys from Lin Industrial and lies the main error, the creation of this type of media is worth the huge money (at last count 214, 6 billion rubles and this is only the first step!) and take a long time (planned development completed before 2030), during which time you can miss out on the initiative. I would add that these carriers are fraught with the risk of another, they are are specialized and can not be used for commercial launches, due to this type of media run extremely rare that coupled with the costly development makes them truly golden.
  
  As proposed to solve this problem in Lin Industrial? Firstly, they offer instead of one super-missile used a few, but available right now, and secondly, they offer a direct flight scheme! Whoa, let's see! It turns out, that would be replaced by one-duty Saturn-5 requires a minimum of six (6) missiles such as the Angara-A5, but the refusal of the scheme Kondratyuka their number should grow more. In Lin Industrial declare that only three! How do they do it?
  
  

  Follow hands h4> To start invited to take the orbital module and re-entry vehicle from the Union, and instead of device-propulsion compartment to use a special version of the Fregat upper stage. Frigate-A (let's call it so) should not only have solar panels and radiators, well, landing support for lunar landing. So something like this:
  
  To send the whole thing to the moon, you need hydrogen upper stage. Fortunately, Russia is coming to the end of the development KVTK (oxy-hydrogen heavy class), this upper stage is designed just for use in the Angara-A5. Here voznikaket first problem carrying capacity of the Angara-A5 is not enough that the economy would pick it up in the Earth's orbit. But everything is solved. In the post about first flight Angara I mentioned that the design of the missile proved that URM-2 is great for A1, but small for A5. The situation was corrected for light Angara and Khrunichev. Khrunichev has plans to modernize the URM-2 for the Angara-A5, by replacing the engine thrust RD0124A 30 ton twin-engine RD0125A with a total thrust of 59 mc. This option and use the offer to Lin Industrial. However, it will still need to use KVTK final ascent to the ship on the reference orbit (just like in the case of Saturn-5). After that, the orbit is a bunch of spacecraft and booster fuel total weight of more than 28 tons.
  
  After re-starting the engines of the hydrogen booster, the ship is sent to the Moon. I must say that this flight should take place for two astronauts in a rather comfortable environment, even in comparison with Apollo. The flight lasts much longer than previously needed for that would get to the ISS, and in the volumes of the Union are not coming three but only two cosmonauts, but what to say, there is even a normal toilet (unless of course it does not have to throw out because of weight savings but more on that below). However, the fuel is in Frigate-L only enough that would reach the orbit of the moon and actually prilunitsya, after which it will be empty tanks. That would not convert two astronauts heroes suicide advance sent to the moon (just using A5 and KVTK) two tankers, which are already familiar to us Frigates-L mounted with spherical tanks with fuel. Speaking of security, if for some reason the moon landing is canceled, the residual fuel that is just enough to send the ship back to Earth.
  
  And on one tanker tanks are not filled completely, so there is an opportunity to send him additional equipment for the astronauts on the lunar surface. Naturally all three landing ships carried out in pre-selected area in sufficient proximity to each other, for that would fill a manned spacecraft for the flight to Earth. Then everything is simple, relatively of course, the astronauts working on the surface of the right time, is charged with the ship and go home. At this all actually.
  Also on the site are painted in detail the stages of construction of a lunar base, but this can not write the next time, unless of course it will be interesting habravchanam.
  
  

  Fly in the ointment h4> Of course in this project has undeniable advantages:
  
  

  • The ship does not expect the return of the expedition in orbit. Solves the problem of having a stable lunar orbit. Due to the influence of the Earth and the Sun, not all stable lunar orbit;
  • Start a possible practically at any time (in the version with docking in orbit - need to start at the exact time or phasing - even if the ship awaiting takeoff module in polar orbit);
  • There are no complicated docking operations at the Earth or the Moon. No need to install docking stations and radio equipment;
  • Well, as mentioned earlier, the use of standard carriers and other components of this program saves a lot of budget and ahead of the competition permits.
