The Hispano-Suiza 14AB, alternatively referred to as the Hispano-Suiza Type 80, was a twin-row, 14-cylinder air-cooled radial engine. After obtaining a license in 1929 to manufacture the Wright Whirlwind engine, Hispano-Suiza utilized this technology to create a range of radial engines with enhanced displacement, increased power output, and a greater number of cylinders.
Among these designs, the 14AB stood out due to its compact configuration and reliable power delivery; production reached around 2,500 units. Despite this, the engine encountered cooling challenges that prompted many aircraft initially equipped with the 14AB to be retrofitted with more dependable powerplants such as the Gnome-Rhône 14M series or imported engines like the Wright and Pratt & Whitney R-1535.
