S.A. Kosberg, belonged to the group of Glushko, Korolev, etc.

-His Design Office is OKB-154 / KB Khimavtomatiki. It is verified that its engines follow a correlative numbering similar to that of Energomash but by inserting a “0” between the letters RD and the order number, for example RD-0120 (instead of RD-120).

-The production range is very extensive. Equally to the official designation corresponds another internal one of the Office.

-The RD-0107 (8D715) from 1959-60 ran on LOX and T-1 (Ker).

-It is used in upper stages of launch vehicles.

- The Kosberg D-1 ran on Isopropyl nitrate, the D-7 as well. They were destined for the air-to-air Toropov missile.

-The initials DU, referring to engines, mean Dvigatelnaya Ustanovka.

-The Kosberg “saga” is classified with the RD-0101 (SK-1) from 1954-58, which ran on LOX-alcohol, and was used on the MiG E-50A.

-The RD-0102 (SK1K) was based on the previous one and was mounted on the Yak-27V. It ran on LOX-Kerosene.

-The RD-0103 delivered 3,528 Kgf on the Sukhoi P-1.

-The RD-0105 (SD-714) equivalent to RO-5 and RD-428, is already installed on a launch vehicle like the Vostok 8K72, in the third stage.

-The RD-0106 of the second stage of the R-9A missile had 4 chambers and was the basis for the RD-0107 and following ones until the RD-0110. It delivered 30 tons of thrust.

“RD-0107”

-The RD-0107 (8D715) from 1959-60 ran on LOX and T-1 (Ker).

-It was used in upper stages of launch vehicles.

-The RD-0107 and RD-0108, were evolutions of the previous -0106, with the same thrust of 30 tons. It had 4 combustion chambers.

-The photograph of the RD-0107 was taken by Mark Wade at the Tsiolkovsky Museum in Kaluga.

-We take advantage to say that Mark is an excellent reference for Russian/Soviet material.

-The RD-0108 is similar.

-The RD-0109 (other references: 8D719, RO-7 and RD-448), was manufactured between 1959 and 1960 for the Vostoks.

-The (14D23) version of the 1990s was intended for Kvant vehicles. It used the vernier system. The RD-0124M versions as well.

-The RD-0126 was used in the upper stages, running on LOX and LH2. The same as RD-0128, RD-0129 and RD-0131.

-The RD-0132 was a cluster of 4 chambers, just like the RD-0133.

-The RD-0143 and its -A version ran on LOX and Liquefied Natural Gas, and were destined for Vozdushniy Start vehicles.

-Curiously, the RD-0146 is the Russian version of the American Pratt & Whitney RL-10A41. It was used in the Centaur's upper stage.

-The 8D415K of the 1960’s was intended for the N-1 concept. It delivered 150 tons of thrust and ran on LOX/Ker.

-The RD-0149 delivered 5 tons of thrust, and ran on LNG and LOX. It was a variant of the RD-0141.

-If so far we have teated the engines that run on LOX, now, in the “200” series they use nitric acid and amines.

-The RD-200 was made on the basis of the SZ.1200 from Isayev, with nitric acid and amine. (RO1-154).

-The RD-0201 that was mounted in the third stage of the V-1100 had four chambers.

-The 8D43 was mounted in the UR500's 1st stage, running on N2O4/UDMH.

-The RD-0203 is a cluster consisting of three RD-0203 and one RD-0204. It delivers 228 tons of thrust.

-The RD-0204 gives 57 tons of thrust.

-The RD-0205 is an engine consisting of an RD-0206 and four RD-0207 in a vernier assembly.

-The RD-0206 gives 58 tons of thrust for the UR-200's 2nd stage.

-The RD-0207 (8D67) was a cluster of four chambers with nitric acid and Asymmetric Dimethyl Hydrazine (UDMH).

“Kosberg RD-0208” (PiP=mw)

-The RD-0209 is a modified -0208 to make the -0211.

-In the second stage of the Proton K there is a cluster of three RD-0210s and one RD-0211.

-The latter (8D412) delivers 60 tons of thrust.

-The RD-0212 (RD-473), has a RD-0213 main chamber and 4 RD-0214s.

-They began to be used in 1967 being the last flight in 1999, on the Proton K-3.

“Kosberg RD-0213 of the -0212” (PiP=mw)

-The RD-0213 gives 59.4 tons of thrust while the four vernier RD-0214s, together give 3.1 tons. Therefore, the total thrust of the RD-0212 was 62.5 tons.

-The RD-0215 ​​was also a cluster consisting of one RD-0217 and three RD-0216s.

-The RD-0221, continues running on N2O4 / UDMH with 8,000 kgf of thrust for the upper stage of a missile. This engine is from the late 1960’s.

“Kosberg RD-0221”

-The last four photographs of this chapter are credited to Dietrich Haesler, via Mark Wade.

-Another small one is the RD-0225 main engine for the propulsion of the Almaz space station. It gives 400 Kgf of thrust.

“Kosberg RD-0225” (PiP)

-Again we find a cluster when dealing with RD-0228. It is an assembly of a RD-0229 main engine plus four RD-0230 verniers.

-The RD-0229, used from 1967 to 1975, was assigned to the second stage of the R-36M. The RD-0229 M engine used LOX / LNG, instead of the usual fuel in this group.

-The RD-0231 gave a thrust of 3 tons and was mounted on the Granit missile.

-The RD-0232 group consisted of one -0234 and three -0233s.

-The RD-0234 was a modified -0233 and was used in three versions using first N2O4 / UDMH, then LOX / kerosene and LOX / Methane (LCH4).

-It had a long nozzle for high altitudes. The RD-0235 gave 25 tons of thrust.

-The RD-0237 is the normal version of the -0235, and was used on the UR-100N to boost the “warhead”. It gave 500 kgf of thrust.

The RD-0242 that began its life in 1977 has reached our days going through several versions.

-The RD-0243 is another cluster of one RD-0244 engine and four RD-0245 verniers.

-The RD-0244 delivers 70 tons on the R-29M and on the Burlak. There is a normal and a cryogenic version.

-The same fuels were used for the RD-0245 that gave 21 tons of thrust.

-The RD-0246 is considered a development of the RD-0243 cluster.

-The Chelomey missile is powered by the RD-0250 or the RD-0251, the latter with four -0236 chambers.

-The RD-0255 is another cluster consisting of an RD-0256 and four -0257s.

-We will mention special engines of this important designer.

-It's about nuclear engines, very fashionable in the mid-1960s.

-The RD-410 NTP was used between 1965 and 1991. It gave 3.6 tons of thrust and was destined for the UR-700M missile.

-The propellant was LH2 or hydrogen, heated by the nuclear thermal reactor.

-It is considered the only operative nuclear rocket engine in the USSR.

“RD-0410” (PiP)

-The RD-0411 was another nuclear study engine to be used on a trip to Mars.

-Other special engines have been the RD-0600, a laser engine with dynamic gas based on a medium of carbon monoxide + air + nitrogen + ethanol.

-The RD-0650TF, used LOX / LH2 / Kerosene, or tripropellant, together with the RD-0700 and -0750 they were alternative engines for the Angara system. They are derived from RD-0120 engines that are under study from 1990 until today.
