UR-700. The UR-700 was Vladimir Chelomei's heavy-lift entry for the Soviet moonshot. It was meant to carry cosmonauts to the Moon on a direct ascent mission in the LK-1 lunar craft. Sergei Korolev's N1 booster and Soyuz 7K-LOK / LK Lander were chosen instead for the mission, and it never left the drawing board. It would have had a payload ...

Russian heavy-lift orbital launch vehicle. The UR-700 was the member of Vladimir Chelomei's Universal Rocket family designed in the 1960's to allow direct manned flight by the LK-700 spacecraft to the surface of the moon. However Korolev's N1 …

UR700使用的RD-270火箭发动机以四氧化二氮和偏二甲肼为推进剂，采用全流量分级燃烧，闭式循环，推力为671吨，推重比达到203，燃烧室压力26.1 MPa，海平面比冲约为301 s。 RD-270的改进版—RD-270M，使用了比RD-270使用的燃料偏二甲肼燃料毒性还要大的戊硼烷燃料，但是比冲提高了43 s。 [1] 卫星百科 航天大模型 已上线，欢迎使用！ 禁止在任何页面泄露 国家秘密 或 商业秘密。 除特殊说明外， 本站点 内容基于 CC BY-SA 4.0 协议 共享，转载需注明来源并按相 …

2020年5月5日 · UR-700使用的RD-270火箭发动机以四氧化二氮和偏二甲肼为推进剂，采用全流量分及燃烧，闭式循环，推力为671吨，推重比达到203，燃烧室压力更是达到了26.1mpa!海平面比冲约为301，与其竞争对手“土星5号”使用的F-1发动机的真空比冲几乎持平！

The UR-700 would be capable of delivering a manned lander directly to the lunar surface, bypassing the need for entering lunar orbit and consequent rendezvous between the lander and "a mother-ship" -- the scheme adopted for NASA's Apollo and Korolev's N1/L3 project. In the "package" with the UR-700 rocket, Vladimir Chelomei proposed his own ...

1968年ur-700定型，第一枚火箭计划于1972年5月发射，在老切的计划中，ur-700在进行两次成功的无人飞行后，第三次将会把苏联宇航员送往月球。 UR-700火箭更像是在N-1火箭计划失败后的备份。

The largest rocket project in the Soviet effort to beat America to the Moon turned out to be also the most elusive for historians. Only during the celebration of the 100th birthday of its creator Vladimir Chelomei in 2014, did detailed information on the incredible nuclear-propelled UR-700 design finally emerge. Previous chapter: UR-700

Russian heavy-lift orbital launch vehicle. In 1969 the Soviet Union began project Aelita, studying the best method to beat the Americans in landing a man on Mars. Chelomei's team reached the conclusion that a Mars expedition would best be launched by an immense vehicle would allow their MK-700 Mars spacecraft to be orbited in two launches.

Russian heavy-lift orbital launch vehicle. UR-700 with high energy upper stage consisting of 7 x RO-31 Nuclear A engines using LH2+Methane propellants with a total thrust of 280 metric tons. Usable third stage propellant 196 metric tons, payload increased to 230 to 250 metric tons. Status: Design 1968. Payload: 270,000 kg (590,000 lb).

2020年9月16日 · 是苏联宇航事业的最伟大的设计师和组织者，其是第一枚射程超过8000公里弹道导弹的设计师，也是世界上第一颗人造人造卫星运载火箭的设计师，同时也是苏联载人登月的总设计师。 瓦连京·彼得洛维奇·格鲁什科是苏联著名的动力物理技术科学家和火箭技术的先驱，苏联最优秀的火箭发动机设计师之一。 20世纪30年代此二人是当时苏联两颗冉冉升起的科研新星，为了同一目标：征服太空而奋斗。 但是一场突如其来的政治风波冲击了整个苏联社会，当然科学 …
