| Soyuz Kontakt P Provisional drawing of Soyuz Kontakt P (Passive) derivative of Soyuz for earth orbit tests of Kontakt lunar orbit docking system. It is uncertain if the Soyuz included the forward-mounted maneuvering engines, or just the passive docking mechansim of the LK lunar lander. Certainly the LK's forward viewing port and docking optical device would have to be included in the orbital module. It is not known if the downward-looking viewport and extensive scallop of the LK cabin was a feature. Credit: © Mark Wade. 20,603 bytes. 600 x 210 pixels. |
Modification of the Soyuz 7K-OK spacecraft with the passive portion of the Kontakt rendezvous and docking system, developed for the lunar orbit rendezvous of the LK manned lunar lander. Crews trained but due to delays with the N1 booster, the spacecraft never flew. Craft.Crew Size: 3. Design Life: 10 days. Orbital Storage: 35.00 days. Total Length: 8.0 m. Maximum Diameter: 2.7 m. Total Habitable Volume: 9.00 m3. Total Mass: 6,560 kg. Total Propellants: 500 kg. Primary Engine Thrust: 417 kgf. Main Engine Propellants: Nitric Acid/Hydrazine. Main Engine Isp: 282 sec. Total spacecraft delta v: 390 m/s. Electric system: 0.50 total average kW. Electrical System: Solar panel span: 9.80 m, area: 14.00 sq. m.
Would have simulated the passive LK lunar lander in an earth-orbit test of the Kontakt docking system.
The passive spacecraft in the second planned test of the Kontakt lunar rendezvous/docking system. One or two of the crew would have spacewalked to the Soyuz 11 Kontakt and returned in the other spacecraft.
Soyuz equipped with the passive Kontakt rendezvous/docking system of the LK lunar lander. Would have docked with Soyuz Kontakt 1.
Soyuz equipped with the passive Kontakt rendezvous/docking system of the LK lunar lander. Would have served as a docking target for Soyuz Kontakt 3.
Final crews selected for a dual Soyuz mission in Earth orbit to test the Kontakt docking system to be used on the lunar landing LOK and LK spacecraft. The Kontakt-P Soyuz would have been the passive spacecraft, simulating the LK lunar lander.
