Hispano-Suiza 14AA explained

The Hispano-Suiza 14AA, also known as Type 79, was a fourteen-cylinder aircraft radial engine used in France during the late 1930s. As Hispano-Suiza lacked recent experience in developing radial engines, it was derived from the licensed Wright R-2600 engine.^[1] Due to reliability problems, the engine was largely supplanted by the similar Gnome-Rhône 14N.

It is not to be confused with the smaller Hispano-Suiza 14AB, which was derived from the smaller Wright Whirlwind series.
