Piaggio P.119
The Piaggio P.119 was an Italian experimental fighter of World War II. It had a relatively novel layout, with a "buried" radial engine mounted mid-fuselage. Only a single prototype was built before the Armistice between Italy and the Allied armed forces, which ended the project.
==Development==
Among the many Italian aircraft manufacturers, during World War II, the majority (such as Savoia-Marchetti and Caproni) designed and built mixed-construction aircraft, or, in the case of CANT, completely made of wood. While Fiat and Macchi built more advanced aircraft, they still tended to have conventional, often obsolete structures, even if of all-metal construction. Only Reggiane and Piaggio mastered advanced, all-metal structures. Of them, Piaggio tended to explore the innovative concepts. The Piaggio P.119 was one of the best examples of these projects. The '5' series fighters are well known, especially the Fiat G.55 and the Macchi C.205, but there were two other fighters on the same level, the Caproni-Vizzola F.6 and the Piaggio P.119, neither of which entered production.
The P.119 was designed (in 1939), to minimise drag by fitting the engine in mid-fuselage in a similar layout to the P-39 Airacobra. It was hoped to improve maneuverability by positioning the engine near the aircraft's centre of gravity, which would also allow a heavy nose-mounted armament.〔 In 1940, Piaggio still had to solve three major issues: contra-rotating propellers, power transmission, and engine cooling.
Giovanni Casiraghi, chief designer of Piaggio, tried to solve the first issue with the P.118 fighter, but without success. It was intended to be powered by two Piaggio P.XI RC 40 engines, each connected to a propeller, but it was not built. The P.119 was built instead and first flew at the end of 1942. Three different configurations were studied before one was chosen.
