TKS SAS


Russian manned spacecraft module. 4 launches, 1977.07.17 (Cosmos 929) to 1985.09.27 (Cosmos 1686). Emergency escape system.

The SAS system abort system for the VA separated the capsule with 15 G's of acceleration from the booster in case of a malfunction and soft landed the capsule 1.0-1.5 km from the launch pad. When the 'Abort' command was sent, the 86 metric ton thrust motor of the ADU pulled the VA capsule away from the pad. 10 seconds from the abort command the ADU/TUD/NO separated and the landing systems went into operation. The braking parachute deployed for seven seconds, followed by the main chute with 1770 square meters of area. The capsule made a soft landing 2 km away. The SAS was jettisoned after the Proton booster had cleared the atmosphere.

Spacecraft delta v: 140 m/s (450 ft/sec).

AKA: Sistem avariyovo spaceniya.
Gross mass: 2,950 kg (6,500 lb).
Thrust: 843.00 kN (189,513 lbf).

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
