Hispano-Suiza 12Hb

Hispano-Suiza piston aero-engines were predominantly piston engines produced by Hispano-Suiza in France from the First World War through to the 1950s. Development of these engines started with the very successful V-8 engines which introduced many features which ensured the success of the Hispano-Suiza line.

The Service technique de l'aéronautique (STAé) used a common designation system for the vast majority of engines produced in France, which signified the major attributes of the particular engines:-

Thus the 12Xgrs was of the X family, with reduction gearing and supercharger, whereas the 12Xhrs was identical but rotated in the opposite direction.

The STAé introduced a numbered attribute indicator from the late 1930s, thus;

12Y-26, 12Y-27 – left and right rotation versions of the same engine.

Basic versions of each engine had even numbers and opposite rotation version were odd numbered.
