Lorraine Dietrich aero engines

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:

1. 12 – the number of cylinders in any configuration (V, straight, W, horizontally opposed, radial,etc. etc.).
2. 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.
3. 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).
4. r – attribute indicators, denoting various attributes that the engine might have, (r = reduction gearing, i = fuel injection, s = supercharged, etc. etc.)
5. 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.
