In 1931 he wrote a proposal for the Italian Air Ministry on the value of jet propulsion, and in 1932 demonstrated a jet-powered boat in Venice.
[3] The "motorjet" that Campini developed to propel the C.C.2 is substantially different from the jet engines of today.
Modern jets are based on the turbojet principle, but Campini's engine was nevertheless a true jet, since it was the reactive force of the burning exhaust gases that pushed the aircraft along.
Tucker asked Campini to both help him develop a turbine powered car, and also used his fame to attempt to secure a US Air Force development contract for the Tucker Corporation.
After the Tucker Corporation folded in 1948, he worked on a number of military projects, including the YB-49 flying-wing bomber.
