'Rocket Engine 0146') is a liquid-fuel cryogenic rocket engine developed by KBKhA Kosberg in Voronezh, Russia. The RD-0146 is the first Russian rocket engine to burn liquid oxygen and liquid hydrogen in the expander cycle, in which turbopumps are driven by waste heat absorbed in the nozzle and combustion chamber. The RD-0146 featured the ...

The RD-0146 became the first Russian rocket engine without a gas generator, and it was also equipped with extendable nozzle extension without a coooling system and it was capable of multiple firings and thrust control in two planes.

The RD-0146 thrust level fell between those of Pratt & Whitney's workhorse RL-10 and the cancelled Euro-American SPW-2000. As of 2007 the engine was being marketed for use in future high performance upper stages for the Onega (improved …

While work on the RO-95 engine was stopped after preliminary design, this engine might be considered as a predecessor to the first modern Russian expander cycle LOX-LH2 RD0146 engine. After 10 years, the Russian rocket companies returned to …

Single-shaft and double-shaft TPA configurations implemented in the RD-120, SSME and RD-0146 engines are described. The criteria used in selecting single-shaft and double-shaft TPA configurations are provided.

RD-0146. The RD-0146 engine is the hydrogen-fueled engine of Russia in the expander cycle, in which turbopumps are driven by waste heat absorbed in the nozzle and combustion chamber, as shown in Fig. 20. The engine produced a specific impulse of 460 s and 10 tonf in a vacuum.

Dec 30, 2021 · A substantial update and history on Russian hydrogen rocketry; the RD-0146 started out almost literally as a Russian RL-10 but it appears technology transfer issues scuttled that effort between...

considered as a predecessor to the first modern Russian expander cycle LOX-LH2 RD0146 engine. After 10 years, the Russian rocket companies returned to the expander cycle of LOX-LH2 engine. In 1999, M. for the RD0146Э engine of 10 tf thrust for «Onega» LV. Russian development of a new generation expander cycle.

RD-0146 是俄罗斯研发的一种氢氧发动机，是苏联/俄罗斯的第一个膨胀循环氢氧发动机。 1988年，应 能源火箭公司 的要求，化工自动设计局开始一个膨胀循环氢氧发动机的研制工作。 该发动机代号RO-95，指标上推力数据为98千牛。 该工程虽然在初样阶段前就停止，但它论证了膨胀循环的可行性，为后来RD-0146的研发奠定基础。 1999年， 赫鲁尼切夫国家研究与生产空间中心 让动力机械科研生产联合体研制一种膨胀循环的氢氧机，预计要在质子号（当时还是 质子K）和新型 …
