How would the "tripropellant" engine have worked? I would assume that the injector plate had two different sets of injectors: one set for kerosene and one set for hydrogen. It would not be an optimized engine, but it helped alleviate a pure hydrogen design's disadvantages (low density & low thrust.)

MAKS struck me as being a pretty realistic spaceplane design, with the airlaunch reducing the drag losses and improving engine efficiency while the drop tank made orbital flight possible w/ realistic mass fractions. But I've read that there were some TPS issues that remained to be solved (the wing leading edges would actually get hotter than those on Shuttle & Buran.) Another big red flag was the approach towards separating the MAKS from the An-225. I'd have a pretty high pucker-factor if I was the An-225 pilot!

A further warning, some models on that site are more or less inaccurate, or even completely wrong (Mikoyan 701 for example), so please take extreme care to compare them with pictures or drawings from other sources before posting. :)

It wasn't my intention to spam the forum with inacurate models. I was concerned that because it is a business, that models of unbuilt aviation and space projects would disappear from USSR-Russian Aviation and Space Collectibles as they were sold or that the site might disappear tomorrow. So I have been replying to threads so that we have copies of the models and can go back to the threads years later to find images of them if needed. Does that make sense?

Alex Panchenko makes claims that these model were actually built at the factories and were intended to be shown at trade shows, museums, or as gifts to important persons.

If I have posted images of models that are inaccurate, can you please report the post to me or a moderator via PM and we will work to get the images deleted?

I'd say regarding Myasishev stuff - Panchenko just used Konstantin Udalov books as source for making outsourcing models. If it was Boeing or Lockheed stuff, Panchenko would be momentally sued for this. Well, recently 'row of eyebrows were rised' (c) Bill Sweetman at EMZ as well on such unlicensed use of Mya designs.

EMZ model shop was never involved in Panchenko's business. So at least his claims regarding Myasichev factory models is lie. Pretty sure that the other model stuff is as 'authentic' as this one. It's like selling these 'hand-sculpted made from environment-friendly and abundant kiln-dried Philippine Mahogany Wood and skillfully handpainted by gifted artists' from ebay telling that this is original Lockheed (Northrop, Boeing) factory models.

No need to remove images, Triton.

Darn it! :( I believed that they had more authenticity and accuracy than models produced at sweatshops in the Phillipines.

A 1992 article on MAKS translated by the US Joint Publications Research Service (JPRS). There's nothing particularly interesting in this article, other than the emphasis on low-cost space transportation.

It appears the X-37B launch has triggered some highly speculative rumours about the possibility of MAKS still being developed. There's a report at http://www.spacevidcast.com/2010/04/28/the-old-maks-russian-space-plane-might-be-new-again-2010-04-28/, with a video version below.

No idea where the relative transportation costs cited have come from.

As the report suggests it all sounds to me like rather wishful thinking by NPO Molniya. The announcement several years ago of the M-55X + C-21 space tourism development with Space Adventures doesn't appear to have gone anywhere (unless someone on here knows different?!)

Update 30-04-2010: Sorry, I'd completely forgotten that I'd previously seen info about the Space Adventures collaboration effectively ending. I've added the relevant links to the thread on the proposed Myasishchev system.

Molniya MAKS-OS Origins

Following some discussion in the ALSV thread, about similarities between US ALSV and Russian spaceplane concepts, I've been trying to find info on the origins of MAKS.

I've not found much very specific on the web, although there is some timeline info in http://www.astronautix.com/lvs/maks.htm. What info I've seen alludes to MAKS growing out of earlier Russian work (eg Spiral) and completed in 1988/9.

However, the excellent Energiya-Buran book (which I've only just obtained :)) does contain rather more background. It says that following on from Sprial, and in parallel with Buran development, NPO Molniya studied various new air-launched systems based on subsonic transport aircraft (to get away from a major Spiral drawback of needing a hypersonic carrier aircraft). The studies described in the book are:

  • 1977 - 1981 Use of Antonov-124 resulting in 'System 49'
  • 1982 Bizan spaceplance (same name also later used for unmanned rocket system in 84-85)
  • Mid 80s plans revised to use more capable An-225 resulting in MAKS

So whatever the influence (if any) of similar US work there does seem to be a natural progression of the various Russian studies going back some years.

This Space.com article mentions dusting off the old plans for MAKS. I'd take it with a grain of salt. But here you go, anyway:

Hi,

found something interesting, MAKS-related, on the bay. It's a 1990s woodcraft handmade model. Not quite sure it is "original" (from the workshops) but the reason why it looks to me interesting is its mimicking of the Buran Analog test vehicle BTS-02 (also known as OK-GLI). Markings taste like it showcases something experimental. It seems to be genuine, like something you'd put on a desk to help visualize what you need to demo. I'd definitively not trash it out and keep it for further reference.

The MAKS Spaceplane: Multipurpose aerospace system (Russian: МАКС)
The MAKS (Multipurpose aerospace system) (Russian: МАКС (Многоцелевая авиационно-космическая система)) was a Soviet air-launched reusable launch system project that was proposed in 1988, but cancelled in 1991. An offshoot of the ENERGIA-BURAN program it had two RD-701 rocket tri-propellant engines based on RD-170 engine from the first stage of ENERGIA rocket and using an Antonov An-225 as a mobile launch platform.
