The Tsyklon-4^[1] 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.^[2] Control system has been developed by JSC Khartron.^[3]^[4]

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.^[5]

Launch facilities

Tsyklon-4 will be launched primarily from the Alcântara Launch Center in Brazil.^[6] Launches from other sites, including the Baikonur and Plesetsk Cosmodromes, are also reported to be planned.^[7]

Development history

Development began in 2002, with the maiden flight aimed for 2006. Following a series of production delays, this has slipped, and is now scheduled for 2014. Alcântara Cyclone Space has been established as a launch service provider for the Tsyklon-4.^[8]

The planned payload capacity of the Tsyklon-4 is 5,500 kilograms (12,100 lb) to a 500 kilometre circular low Earth orbit, or 1,700 kilograms (3,700 lb) to geosynchronous transfer orbit.^[9]

In 2008, it was reported that Brazil may pull out of the programme in favour of an alternative partnership between it and Russia to develop an Angara-derived rocket.^[10] However late 2009 Ukrainian President Viktor Yushchenko and Brazilian President Luiz Inácio Lula da Silva signed a joint declaration which included a commitment to launch the first Tsyklon-4 by the end of 2010 from Alcântara.^[11] This did not occur, and it is now to launch no earlier than 2015.^[12]
