Energia - Buran Space Transportation System

I had forgotten about this image before coming across it again today in the Transport Amphibious Platforms (TAP) concepts thread over in Naval Projects:

(h/t borovik)

A Soviet Navy TAP-30 'small landing craft', presumably being used to transport a Buran back from one of the more remote back-up landing sites.
(Though for a while, I was wondering if it was actually an illustration of the OK-92 precursor design being transported.)

Myasishchev VM-T Atlant/Buran: The Primordial Titan.

The astonishing Atlant was an oversize cargo aircraft used in the Energiya/Buran space program. A derivative of one of my favourites, the 3MN-2 (M-4/3M family), the Atlant was designed as a stopgap…

Myasishchev VM-T Atlant: The Primordial Titan (II).

Really nice pic of the Atlant, first carrier for both the Buran shuttle and the Energiya booster. Now a museum piece, the Atlant has the “Egg” on his back; Payload 3GT -the “Egg&#…

Ekranoplans and space shuttles, what's not to like ? add a zeppelin and a battleship in the background maybe ? :p

I came across another photo of the Yamal mockup next to the Buran-Analogue 002
taken in 1999, at Zhukovsky, via this blog post on the excellent "Drew Ex Machina" spaceflight and astronomy blog

The Day I Saw Buran

Life is filled with surprises big and small. Between 1994 and its cancellation in 2004, I was involved as a member of the American science team in the joint US/Russian RAMOS (Russian American Obse…

Many tests of elements of rocket and space technology are carried out in flying laboratories. This happened most fully during the creation of the Buran orbiter in the 1980s. In particular, the MiG-25 and Tu-154 laboratory aircraft were used to test the ship's automatic landing system.

For the final testing of the final stage of the Buran's flight and its landing, including in automatic mode, a full-size analogue aircraft BTS-002 was built. Its tests were carried out in Zhukovsky near Moscow - at the Gromov Flight Research Institute together with the Experimental Machine-Building Plant named after V.M. Myasishchev. It flew for the first time on November 10th, 1985, piloted by Gromov Flight Research Institute test pilots Igor Volk and Rimantas Stankevicius. They were originally planned as the crew for the first manned flight of the Buran.

Как была устроена индивидуальная СОЖ на корабле «Буран»

научно-производственное предприятие «Звезда» (АО «НПП «Звезда»), разработало для многоразовой космической системы (МКС) аварийно-спасательный скафандр «Стриж» и катапультное кресло К-36РБ. Катапультное кресло К-36РБ в сочетании с СК «Стриж» обеспечивали возможность катапультирования членов...

Катапуьтное кресло К-36РБ: Катапультирование из «Бурана» на высотах 35-40км. при скорости 3-4 мах

Под креслом видны разгонные блоки (РБ) и дополнительные штанги стабилизации, которые отсутствуют в авиационных модификациях К-36 Изначально требования к катапультному креслу для системы «Энергия-Буран» ограничивались спасением экипажа во время летных испытаний на заданных режимах полета...

Скафандр "Стриж" для корабля «Буран» - катапультирование на скорости 4 мах.

Но главной изюминкой скафандра «Стриж» было требование обеспечения безопасности членов экипажа при катапультировании на активном участке полета при скоростях М=3-4 мах и высотах 30-40км. В этих условиях, помимо аэродинамических нагрузок, остро вставала проблема сильного нагрева скафандра.

I keep pushing for SLS to evolve into Shuttle II if Starship doesn’t work out. With hydrogen engines off the orbiter, it can have better handling characteristics.

And even worse economics!

Oh, boy, a reusable payload shroud sucking up the payload potential of a launch vehicle that costs a quarter billion dollars a pop!
 
It is still simpler part count wise. It just needs some backers to get it away from Boeing
 
A bit off topic, but kinda on topic; Bald is a rapist and a sex tourist. Used to watch him before but not ever since finding that out. In general he is a tool and a creep as well.

On topic; Personally i have never cared about Buran but Energiya is an engineering marvel. Such a shame it only flew twice and never got close to its true potential.

Same feelings overall, albeit mixed. My POV is that the very concept of space shuttles was deeply flawed, but the Russian take at it was interesting nonetheless. Not only an orbiter (Buran) but also the full and entire family of rockets spun out of it: Energiya, Zenit, and all the others.
Something the US Shuttle could not do, because the mix of SSME and SRB and ET could not make interesting ELVs (SRB-X, Jarvis, Ares 1, Ares V, SLS... meh). Except perhaps DIRECT's Jupiter 120.

In File 29 about air transport of loads, what are the longer boosters/Blok A without recovery systems under the name 23/25 GT ? they're a good 7-8m longer than the Block A used for Energia.

"Blocks A of the Vulcan launch vehicle are not equipped with recovery means and associated elements. Compared to blocks A of the Energia rocket, the volume of fuel tanks has been increased due to cylindrical inserts 7 m long."

Ah so Vulcan boosters were indeed longer, thanks

An upgraded Zenit based on Vulcan!Block A with RD179 would have be interesting.
 
«Biser-4» (SH16M), the Buran's digital on-board computer

✔ Developed by the Pilyugin Center NPTsAP (Moscow), it had the structure of the American IBM 360 computer.

✔ Eight of these computers were planned to be used on the Buran, forming two identical computer systems of four synchronized computers each (Central System and Peripheral System). On the first (and last Buran flight) only four Biser-4 computers were used. These computers provided redundancy to all Buran control operations, and were synchronized by hardware. The computer system had a single quartz oscillator that supplies all eight Biser-4 computers with a single sequence of clock pulses with a frequency of 4 MHz and an interrupt period of 32.8 ms. Since the reference oscillator also had to meet the requirement of “reliable operation under two faults”, it had five redundancy channels, and at the output of which the “three out of five” voting scheme was installed.

✔ The Buran computer system had three magnetic tape memory units (MMUs) with a capacity of 819 KB (32-bit words) each for storing software and loading it into the computers' RAMs during flight. In addition to the onboard programs, the MMUs could also store information useful for the onboard displays used during manned flights. To ensure reliability, the information for each ML was duplicated.
