Differences between Dyna-Soar and Spiral

Although having basically the same mission, Dyna-Soar and Spiral were radically different vehicles. For example:

     or Saturn I, Soviet engineers opted for a midair launch scheme for Spiral. Known as "50 / 50", the idea was that the spaceplane and a liquid fuel booster stage would be launched at high altitude from the back of a large, airbreathing mothership travelling at hypersonic speeds. The idea was similar to that used by the United States in launching the D-21 Tagboard reconnaissance drone from the back of the A-12 Oxcart

     project.
  • Dyna-Soar was designed with a fixed, delta-wing planform, while Spiral featured an innovative variable-geometry wing. During launch and reentry, these were folded against the sides of the vehicle at a 60-degree angle, acting as vertical stabilizers. After dropping to subsonic speeds post-reentry, the pilot activated a set of electric actuators which lowered the wings into the horizontal position, giving the spaceplane better flight characteristics.
  • Spiral was built to allow for a powered landing and go-around maneuver in case of a missed landing approach. An air intake for a single Koliesov turbojet was mounted beneath the central vertical stabilizer. This was protected during launch and reentry by an electric clamshell door, which would open at subsonic speeds. By comparison, Dyna-Soar was designed primarily for a once-off, unpowered deadstick landing, although some documentation claims that its emergency solid-fuel escape rocket (the third stage engine from an LGM-30 Minuteman

     were to have been used in the heatshield structure of the X-20. Spiral was to have been protected by what Soviet engineers termed "scale-plate armour": individual steel plates hung from articulated ceramic bearings to allow for thermal expansion during reentry. Several BOR (Russian acronym for Unpiloted Orbital Rocketplane) craft were built and launched to test this concept.
  • In the event of a booster explosion or in-flight emergency, the insulated crew compartment of Spiral was designed to separate from the rest of the vehicle and parachute to earth like a conventional ballistic capsule; this could occur at any point in the flight. Such an escape crew capsule

     was also considered for Dyna-Soar, but American engineers eventually opted for a solid-fuel escape rocket that would kick the spaceplane away from an exploding booster, saving both pilot and spacecraft.
  • Much like today's Space Shuttle, Dyna-Soar was designed with a small payload bay behind the pressurized crew module. This could be used for lofting small satellites, carrying surveillance equipment, weapons or even an extra crewmember in a pop-in cockpit. Spiral, on the other hand, appears to have been intended to carry only its pilot. Presumably, this was because the extra space which could have held a payload bay was needed for the Koliesov turbojet and its fuel tanks.
  • Both Dyna-Soar and Spiral were designed to land on skids. The landing skids on Dyna-Soar were designed to deploy from insulated doors on the underside of the vehicle, like a conventional aircraft. Soviet engineers, most likely concerned about heatshield integrity, designed the landing skids on Spiral to deploy from a set of doors on the sides of the fuselage just above and ahead of the wings. This unusual arrangement resulted in a hard landing on at least one occasion.

Pilots

A cosmonaut training group for pilots assigned to fly this vehicle was formed in the early 1960s. It went through many changes and was eventually dissolved entirely. Known members included:
  • Gherman Titov

  • A. G. Fastovets, who piloted the vehicle during the majority of its atmospheric tests.

Uragan

Although Spiral itself never made it to the launch pad, it is rumoured that the design was reused and enlarged to build a piloted space interceptor known as "Uragan" (Russian for "Hurricane") in the 1980s. This craft was to have been launched by a Ukrainian-built Zenit expendable booster

 cosmonaut groups, consisting of six in the first group and at least three in the second, were selected and trained to pilot the vehicle. The possibility that the shuttles could now be intercepted and shot down caused quite a stir in the US Department of Defense at the time, which issued several artists' conceptions showing the vehicle on the pad, in space, etc.
