The Piaggio P.XIX was an Italian aircraft engine produced by Rinaldo Piaggio S.p.A. during World War II and used to power aircraft of the Regia Aeronautica.
Development
[edit]The engine was part of a line of 14-cylinder radial engines developed from Piaggio based on the Gnome-Rhône Mistral Major, which was itself loosely based on the Bristol Jupiter.[1] It was derived from the earlier P.XI but with a higher compression ratio.
Variants
[edit]- P.XIX R.C.45 Turbine
- Geared, rated altitude 4,500 m (14,800 ft)
- P.XIX R.C.50
- Geared
Applications
[edit]- CANT Z.1007ter
- Macchi MC.200bis prototype
- Reggiane Re.2002
The engine was also fitted experimentally to single versions of the IMAM Ro.57 and Savoia-Marchetti SM.82 (serial number MM.60591).[2]
