Voskhod Programme - Design

Design

The Voskhod spacecraft was basically a Vostok spacecraft that had a backup, solid fuel retrorocket added to the top of the descent module. The increased weight of the craft was compensated for by improvements to the R-7 Semyorka-derived booster. The ejection seat was removed and two or three crew couches were added to the interior at a 90-degree angle to that of the Vostok crew position. However, the position of the in-flight controls was not changed, so the crew had to crane their heads 90 degrees to see the instruments.

In the case of Voskhod 2, an inflatable exterior airlock was also added to the descent module opposite the entry hatch. The airlock was jettisoned after use. This apparatus was needed because the vehicle avionics and environmental systems were air-cooled, and depressurization in orbit would cause overheating. There was no provision for crew escape in the event of a launch or landing emergency. A solid fuel braking rocket was also added to the parachute lines to provide for a softer landing at touchdown. This was necessary because, unlike the Vostok, the Voskhod descent module landed with the crew still inside.

Famous quotes containing the word design:

    Delay always breeds danger; and to protract a great design is often to ruin it.
    Miguel De Cervantes (1547–1616)

    What but design of darkness to appall?—
    If design govern in a thing so small.
    Robert Frost (1874–1963)

    Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.
    Henry David Thoreau (1817–1862)
