Russian manned spacecraft. Study 2008. This conical, six-crew space capsule represented the Russian Space Agency's preferred design to support Russian spaceflight in the 2018-2068 period.

AKA: Pilotiruemiy korabl. Status: Study 2008. Payload: 3,300 kg (7,200 lb). Gross mass: 11,000 kg (24,000 lb). Height: 7.70 m (25.20 ft). Diameter: 3.80 m (12.40 ft).

By mid-2008 the Russian Space Agency, after evaluating Energia's various Kliper proposals, and Khrunichev's TKS derivatives, was supporting development of a conical spacecraft, its aspect ratio similar to the Gemini spacecraft, with an unusually deep hemispherical heat shield. Used with the Angara 5P booster launched from Vostochniy, the design would exceed the Agency's requirements for its new-generation piloted spacecraft in several areas. It would not subject the crew to more than 3 G's during normal ascents to orbit and re-entries, or more than 12 G's in an emergency abort during the launch phase.

The spacecraft would be placed in a 135 km x 440 km, 51.6 deg orbit on the baseline mission to the ISS. Its on-board propulsion system would bring it to a rendezvous and docking with the station. On such missions the spacecraft could bring up to 3300 kg of payload, in addition to the crew of six, to the station. 500 kg of payload could be returned to earth. The capsule provided a total of 28 cubic meters of pressurized volume, 18 of it usable, 12 of it habitable, or 2 cubic meters per crew member.

The capsule provided sufficient lift for a cross-range of 180 km to either side of the ballistic re-entry landing point, and 600 km along the orbital track. This meant it could return the crew to Russian territory on 7 to 8 orbits per day, or nearly half the time. Landing precision was within 2 kilometers of the aim point, and 75% of the capsule could be reused after a mission.

Variations of the design could be used for various missions:

The baseline spacecraft would meet the Russian Space Agency's basic requirements which were as follows:

Crew Size: 6. Orbital Storage: 365 days. Habitable Volume: 12.00 m3.
