Lorraine-Dietrich aero-engines

Lorraine-Dietrich was a French automobile and aircraft engine manufacturer from 1896 until 1935, created when railway locomotive manufacturer Société Lorraine des Anciens Etablissments de Dietrich and Cie (known as De Dietrich et Cie, founded in 1884 by Jean de Dietrich) branched into the manufacture of automobiles. The Franco-Prussian War divided the company's manufacturing capacity, one plant in Niederbronn-les-Bains, Alsace, the other in Lunéville, Lorraine.^[1]

Aircraft engines[]

Designations[]

Letter system[]

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

12 – the number of cylinders in any configuration (V, straight, W, horizontally opposed, radial, etc. etc.).
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.
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).
r – attribute indicators, denoting various attributes that the engine might have, (r = reduction gearing, i = fuel injection, s = supercharged, etc. etc.)
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.
