Viking series of sounding rockets was built by Glen Martin for the
Naval Research Laboratory (NRL).
Viking rocket was more than a replacement for the V-2. Itís engine was a
servo-controlled gimballed motor for attitude control during flight. In
V-2 was controlled by graphite vanes placed in the exhaust flame. Breakdown
of these vanes often caused launch failures. Another modern feature of the
Viking rocket was the integration of the tanks in the fuselage of the
of the viking rockets was exactly of the same design, because NRL and Martin
constantly made small improvements on the rockets.
But the rockets was designed in two basic designs.
But the rockets was designed in two basic designs.Viking 7 and itís predecessors were of the first type named RTV-N-12, and Viking 8 to12 were of a totally new design best known by the Viking 10. This more avanced type was named RTV-N-12 a.
first Viking rocket was launched a White Sands proving ground on may 3
and reached 80 km (50 miles).
Viking 7 was launched on august 7, 1959. It reached an altitude of 218 km (136 miles), which was a new altitude record.
The length of the viking 7 was 14,81 m (48 ft 7 in) and it was so small, that it could be moved on a special cart pulled by an ordinary jeep.
Eric Truax has made a mod-kit for this model, so it can be fitted with a mmx-rocket-engine:
