RD-191 Glushko Lox/Kerosene rocket engine. 2079 kN. Isp=337s. Proposed for stage 1 of Angara. Single chamber from 4-chamber RD-170 would have been cheap and fast to develop. Only reached the draft project stage by 2003. Gimbaling +/- 8 degree in two planes. More...
Associated Launch Vehicles
Angara 1.1 Russian orbital launch vehicle. The initial flight version would be the Angara 1.1, featuring a single URM core module with the existing Briz upper stage. Payload would be 2.0 tonnes to a 200 km / 63 deg orbit). Other vehicle variants were numbered according to the number of URM's. More...
Angara 1.2 Russian orbital launch vehicle. First planned upgrade of Angara, the 1.2 version would use a new Block I lox/kerosene upper stage. Payload would be 3.7 tonnes to a 200 km / 63 deg orbit. More...
Angara 3A Russian orbital launch vehicle. The Angara 3A was a proposed variant of the modular launch vehicle that would use two universal rocket modules (URM's) as boosters flanking one URM in the core, with a Lox/Kerosene upper stage. It could put 14 tonnes into low earth orbit More...
Angara 5A Russian orbital launch vehicle. The Angara 5A was a proposed variant of the modular launch vehicle that would use four universal rocket modules (URM's) as boosters surrounding one URM in the core, with a Lox/LH2 upper stage. It could put 5.0 tonnes into geosynchronous orbit, or 8.0 tonnes into geosynchronous transfer orbit. More...
KSLV-I In 2005 it was announced that the KSLV-I would not fly until 2007. It was now a completely different vehicle, consisting of a first stage derived from the Russian Angara launch vehicle, and a solid propellant second stage of South Korean manufacture. First launch 2009.08.25. More...
KSLV-III South Korean launch vehicle, to consist of a Russian Angara first stage, a South Korean liquid propellant second stage, and a South Korean solid propellant apogee kick motor. Scheduled for first flight by 2015. In August 2006 the Korean press reported that the first and second stages would both be Angara-UM modules... how this configuration would work (stacked versus parallel) was unclear. More...
KSLV-II South Korean launch vehicle, originally scheduled for first flight by 2010. Evidently it would have consisted of a Russian Angara first stage and a South Korean liquid-propellant second stage. In August 2006 it was reported in the Korean press that this launcher configuration was cancelled. More...
Lox/Kerosene Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. In January 1953 Rocketdyne commenced the REAP program to develop a number of improvements to the engines being developed for the Navaho and Atlas missiles. Among these was development of a special grade of kerosene suitable for rocket engines. Prior to that any number of rocket propellants derived from petroleum had been used. Goddard had begun with gasoline, and there were experimental engines powered by kerosene, diesel oil, paint thinner, or jet fuel kerosene JP-4 or JP-5. The wide variance in physical properties among fuels of the same class led to the identification of narrow-range petroleum fractions, embodied in 1954 in the standard US kerosene rocket fuel RP-1, covered by Military Specification MIL-R-25576. In Russia, similar specifications were developed for kerosene under the specifications T-1 and RG-1. The Russians also developed a compound of unknown formulation in the 1980's known as 'Sintin', or synthetic kerosene. More...
