Add article description


Hispano-Suiza piston aero-engines were predominantly piston engines produced by Hispano-Suiza in France, Spain, and under licence in the United Kingdom, the United States and Russia from the First World War through to the 1950s. Development of these engines started with the very successful V-8 engines which introduced many new features which ensured the success of the Hispano-Suiza line.

Designations

Letter system

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:-

  1. Manufacturer - In this case Hispano-Suiza
  2. 12 - the number of cylinders in any configuration (V, straight, W, horizontally opposed, radial, etc.).
  3. Y - the family letter in capitals (note: in at least two instances the family designator consisted of two letters in capitals e.g. 14AA and 14AB), advancing alphabetically. (note:Hispano-Suiza avoided W to avoid confusion with W / Broad-arrow engines)
  4. a – sub variant indicator, (which could also indicate the rotation of the engine, where otherwise identical engines with opposite hand rotation were built, e.g. 12Ndr anti-clockwise and 12Nfr clockwise).
  5. r – attribute indicators, denoting various attributes that the engine might have, (r = reduction gearing, i = fuel injection, s = supercharged, etc.)
  6. 1 - sub-sub variants were denoted by using a number after the letters, (e.g. 12Xhrs and 12Xhrs1), usually indicating differences in ancillary equipment.

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

Number system

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.
