Hispano-Suiza piston aero-engines
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 used a common designation system for the vast majority of engines produced in France, which signified the major attributes of the particular engines:-- Manufacturer - In this case Hispano-Suiza
- 12 - the number of cylinders in any configuration.
- Y - the family letter in capitals, advancing alphabetically.
- a – sub variant indicator,.
- r – attribute indicators, denoting various attributes that the engine might have,
- 1 - sub-sub variants were denoted by using a number after the letters,, usually indicating differences in ancillary equipment.
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.
