}} The Tsyklon-4 or Cyclone-4, also known as Tsiklon-4, is a Ukrainian carrier rocket which is being developed for commercial satellite launches. Derived from the Tsyklon-3, it has a new third stage, a larger payload fairing, and a modernised flight control system compared to its predecessor.〔(【引用サイトリンク】publisher=NPO InterCoS )〕 Control system has been developed by JSC Khartron.〔(Control systems for intercontinental ballistic missiles and launch vehicles )〕〔(Krivonosov, Khartron: Computers for rocket guidance systems )〕 == Specifications == Tsyklon-4 is a three-stage-to-orbit expendable launch system built on the successful Tsyklon-3 rocket and it uses its first two stages. The new features are mostly concentrated in the newly developed third stage: * The third stage has a three times larger propellant capacity; * The new rocket engine RD-861K with multiple ignition capability (3 to 5 times); * A modern western-like control system capable of precise orbit injections; * A new fairing derived from Ariane 4 is under development. It has a diameter of 4 meters, controlled temperature and cleanness conditions inside. Tsyklon-4 will also improve the fueling system, allowing safe capture of toxic vapors from the Tsyklon's hypergolic propellant. The new system, operated from a near-equatorial launch facility, will be able to deliver 5,300 kg into low Earth orbit, or up to 1,600 kg into a geostationary transfer orbit.〔http://www.alcantaracyclonespace.com/phocadownload/cyclone4_users_guide.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tsyklon-4」の詳細全文を読む スポンサード リンク
