Manufacturer's Designation: 7K-L1E. Class: Manned. Type: Lunar orbiter. Nation: USSR. Manufacturer: Korolev.

Modification of Soyuz circumlunar configuration used in propulsion tests of Block D stage. The L1E provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions. Probably included a dummy descent module (not recovered).


Specification

Total Mass: 10,380 kg.


Soyuz 7K-L1E Chronology


28 November 1969 Soyuz 7K-L1E s/n 1 Program: Luna. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K / 11S824. FAILURE: First stage malfunction. Mass: 10,380 kg.

Attempted test flight of Block D upper stage in N1 lunar crasher configuration. Payload was a modified Soyuz 7K-L1 circumlunar spacecraft, which provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions. Mission flown successfully over a year later as Cosmos 382.


02 December 1970 Cosmos 382 Program: Lunar L3. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K / 11S824. Mass: 10,380 kg. Perigee: 2,384 km. Apogee: 5,269 km. Inclination: 55.9 deg. Duration: 8,549.30 days.

Test of Block D upper stage in its N1 lunar crasher configuration in earth orbit. The three maneuvers simulated the lunar orbit insertion burn; the lunar orbit circularization burn; and the descent burn to bring the LK lunar lander just over the surface. Payload was a modified Soyuz 7K-L1 circumlunar spacecraft, which provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions.
Maneuver Summary:
190km X 300km orbit to 303km X 5038km orbit. Delta V: 982 m/s
318km X 5040km orbit to 1616km X 5071km orbit. Delta V: 285 m/s
1616km X 5071km orbit to 2577km X 5082km orbit. Delta V: 1311 m/s
Total Delta V: 2578 m/s.
