Draken Harald Hårfagre
Draken Harald Hårfagre () is a large Viking longship built in the municipality of Haugesund, Norway. "Draken Harald Hårfagre" brings the seafaring qualities of a warship from the old Norse sagas to life. It is a ship that combines ocean-crossing sailing capabilities with a warship's use of oars.
Viking (rocket)
The Viking was roughly half the size, in terms of mass and power, of the V-2. Both were actively guided rockets, fueled with the same propellant (Ethyl alcohol and liquid oxygen), which were fed to a single large pump-fed engine by two turbine driven pumps. The Reaction Motors XLR10-RM-2 engine was the largest liquid-fueled rocket engine developed in the United States up to that time, producing (sea level) and (vacuum) of thrust. Isp was and respectively, with a mission time of 103s. As was also the case for the V-2, hydrogen peroxide was converted to steam to drive the turbopump that fed fuel and oxidizer into the engine. As its V-2 counterpart, it also was regeneratively cooled.
