This aircraft had a 900 hp Isott-Fraschini in the fuselage driving a variable pitch ducted-fan compressor supplying air to a after burner. Could be flown with only the ducted-fan.
This "Jet-like" propulsion was invented in 1931 by the Italian aeronautics engineer Secondo Campini. Sometime called a thermo-jet. This jet was tested on a jet-powered boat in Venice.
This is the second prototype.
