Type | Air cooled radial |
National origin | Italy |
Manufacturer | Piaggio |
Designer | Renzo Spolti |
Major applications | IMAM Ro.43 |
Developed from | Piaggio Stella P.IX |
The Piaggio P.X, or Piaggio Stella P.X, was an Italian nine-cylinder radial aircraft engine produced by Rinaldo Piaggio S.p.A. Based on experience license-producing Gnome et Rhône designs, the engine was used to power a number of aircraft during World War II, including the IMAM Ro.37bis and IMAM Ro.43, used extensively by the Regia Aeronautica and Regia Marina respectively.
Piaggio acquired a license from Gnome et Rhône in 1925 for their engines derived from the Bristol Jupiter. [1] The designs proved successful and, using this experience, the company designed a range of related radial engines named "Stella", meaning star. [2] The design was led by the engineer Renzo Spolti. [3] The engines were initially known by their number of cylinders, so the first nine-cylinder model in the range was the P.IX of 1933. However, a progressive number in Roman numerals was used as the design progressed, so the P.IX was followed by the P.X. [2]
The Stella P.X was a nine cylinder version of the P.VII. [4] It retained the same bore and stroke as the original Gnome-Rhône designs, 146 mm (5.7 in) and 165 mm (6.5 in) respectively, but was substantially more powerful than the comparable 9K. [3] The engine had a two piece aluminium alloy crankcase, steel barrels for the cylinders and aluminium alloy heads. A Piaggio T2-80 updraught carburettor was fitted. [5] The basic version, the R., had reduction gear, while the R.C. was also equipped with a compressor. [2]
The engine powered the Italian aircraft that served during World War II. [6] The IMAM Ro.43 was particularly noteworthy for its performance in the Battles of Cape Spartivento and Cape Matapan. [7]
