The guided missile RSA was a beam-guided anti-aircraft missile .

history

The RSA guided missile and its launch vehicle were developed from 1946 to 1958 by the Swiss manufacturers Oerlikon-Bührle and Contraves . Shortly after the end of the Second World War , the in-house development of anti-aircraft guided weapons began in Zurich . The rocket, guided by a beacon, used nitric acid and kerosene as fuel, nitrogen served as the propellant. The gimbal swiveling combustion chamber allowed thrust vector control at high supersonic speeds .

The launcher was used for test shooting in Walenstadt , S-chanf , the Oberalp Pass , in the United States and France . The United States bought some of these guided missiles in order to gain experience for its own anti-aircraft guided missile development. With this guided weapon, Oerlikon-Bührle created the basis for the development of the RSC / D guided weapon system .

A guided missile RSA on its launch vehicle and the target tracking radar and beacon transmitter mounted on a mount of the 34 mm Flab Kan are exhibited in the Flieger-Flab-Museum in Dübendorf.

Tracking radar and beacon transmitter

The target following and lighting radar, which is mounted on a mount of the 34mm Flab Kanone 38, has a three-axis directional system for the target following antenna and the beacon transmitter, so it can precisely track targets "overhead". The guided weapon steers itself into the center of the beacon. It was made by Contraves AG and the BBC. Target following system with conical scan radar and parabolic antenna. Beacon transmitter with rotating primary radiator without reflector. Electronic drive of the three straightener axes.
