V2 ROCKETS ORIGINAL V-2 ROCKET GYROSCOPE

Sign In to see what this sold for

Gyro-type accelerometer that was developed for and used in the inertial guidance system of the German V-2 rocket during WW II. This includes a preset device for propulsion cutoff. This system was very straightforward and dependable. A great many of these missiles were fired with an accuracy of 5 km (3.1 miles) over a range of 200 km (125 miles). The use of an electronic guide beam for additional yaw control reduced lateral error to about 800 meters (½ mile). This integrating gyro-type accelerometer was coupled to a disk integrator. These were mounted on the stabilized platform along the major axis of the missile. This device calculated velocity and distance and determined propulsion cut-off time. Lot is accompanied by Army Ballistic Missile Agency Manual: 'A History of Inertial Guidance', by F.K. Mueller, Redstone Arsenal, AL c. 1959. Overall dimensions about 7x7½"x4¾", mainly aluminum & steel with detailed wiring, movable gyroscope & dials with what appears to be a mica window in removable top of unit which exposes numbers on wheel for settings. Base is hand-engraved with the name: A.Ott, Kempten, the number '240', cover has German words 'Fest' & 'Lose' by a locking switch. The first of these we have ever offered. A wonderful opportunity to acquire & own an enormously important piece of the history of rocketry. This item came from Germany and eventually was consigned to us from Huntsville, AL. Excellent condition, ideal for museum or private collection. An extraordinary opportunity."
