1970 Soviet test spaceflight
Kosmos 382
was a
Soviet
Soyuz 7K-L1E
modification of a
Soyuz 7K-L1 "Zond"
spacecraft and was successfully test launched into
Low Earth Orbit
on a
Proton rocket
designated as (Soyuz 7K-L1E No.2) on December 2, 1970.
The main purpose of the mission was to test the
N1/L3
spacecraft's
Block D
lunar orbit insertion
/descent stage by simulating the lunar orbit insertion burn, the lunar orbit circularization burn and the final lunar descent burn. Over the course of five days, the Block D stage was ignited three times to raise the initial ~190 km × ~300 km × 51.6° orbit to a final 2577 km × 5082 km × 55.87° orbit. The Block D stage was fitted with cameras in the tanks to monitor the fuel and oxidizer behaviour in weightlessness and during acceleration.

Kosmos-382 also carried other experiments, including a prototype environmental control subsystem named "Rosa" for producing potable water from atmospheric condensate exhaled by cosmonauts onboard Soviet manned spacecraft. This system was later used on the
Salyut
space stations in the 1970s and 1980s.

The following maneuvers were performed:
- 190 km x 300 km orbit to 303 km x 5038 km orbit (
delta-V
=982 meters/second;
- 318 km x 5040 km orbit to 1616 km x 5071 km orbit (deltaV= 285 m/s);
- 1616 km x 5071 km orbit to 2577 km x 5082 km orbit (deltaV= 1311 m/s).
