Rocket engines

Original post (in russian):

In our childhood every other kid for sure wanted to become an austronaut, or, at least, to involved in space exploration in some way. Nowadays the only thing we might see in space industry is total devastation and oblivion. In most cases, that’s true.

Though I’m an engineer, I was always charmed and amazed the the engines, especially by aircraft and rocket ones. For example, the liquid rocket engine may seem a simple thing at first sight: one may just pour some fuel into the combustion chamber and it’s done. But if you look deeper, you’ll find more interesting stuff.

There is a facultee in Dnipropetrovsk National University, where people study to create and launch these engines. So, when student graduates, he becomes an extremely valuable employee. KB “Yuzhnoe” gives a proof: lots of people are hired to develop engines for US, EU, Brazilian and Russian customers. As an example — the recent launch of carrier rocket ‘Vega’ 13 feb 2012.

KB Yuzhnoe also designed the Moon modules in the USSR.
The “E” block’s engine from the Soviet Moon Program. Only three items left — two in Dnipropetrovsk, one in Moscow Aviation Institute.
Its’ traction characteristics, lifetime and possibility of multiple launch in vacuum make this engine unique.
The Moon Vehicle consists of austronaut’s pressurized cabin, compartment with orientation engines and Attach System, equipment bay, Lunar unit and the “E” block.

Boris Ivanovich Gubanov was a lead block “E” constructor. The engine prototype was designed by KB-4 with Ivan Ivanovich Ivanov as a lead. The engine tests were started Khimmash Research Institute in Podmoskovie, which was visited by KB Yuzhnoe team every month. The engine crush test result was not even achieved: it worked infallibly during 10000s, when only 470s point was required.
The “E” block had to provide the Moon Vehicle’s braking, maneuver and landing on the Moon’s ground. The time on the Moon’s ground* is between 6 and 24 hours. Then, the vehicle blasted off the Moon’s ground and performed acceleration via the “I” block (designed in OKB-2 under the guidance of A. M. Isaev).

The entire engine of the “E” block.
The RD-250 engine, which is installed on the first stage of the ‘Cyclon’ mother missile.
It was also installed in the R-36 missile’s first stage.
15D12 (RD-857) was designed in KB Yuzhnoe under the guidance of I. Ivanov in 1967 and to be installed on the second stage of the RT-20 mobile complex. Unfortunately, there were only test units of this item, but the RD-862 engine, which was installed on the second stage of the 15A15* transcontinental ballistic missile, was based on it.
The giant liquid rocket, which, unfortunately, has no known marking. There is a supposition that this is a 8K66 missile’s second stage engine (only several test units were released).

Injector combustor.
Nozzle solid engine with tilting mechanism.
More injectors.
Let’s tal about aviation now. This is a D-36 engine, made by Zaporizhzhian KB “Progress”.
The three-shaft turbofan engine.
It’s available since 1976. It was installed on Yak-42 airliners, An-72 & An-74 freighters.
The compressor is almost assembled.
