Antonio Ferri (5 April 1912 – 28 December 1975) was an Italian scientist, prominent in the field of aerodynamics, with a specialization in hypersonic and supersonic flight.
Born in 1912 in Norcia, Italy, from 1937 he conducted research in Guidonia Montecelio, where the most prominent and advanced research on high-speed aerodynamics was taking place. In 1938, at the age of 26, he received Italy's highest prize for science, the Premio dell'Accademia d'Italia for science.Antonio Ferri, 1912-1975," by Adolf Busemann, Memorial Tributes: National Academy of Engineering, Vol. 1, 1979, pp. 56-60. Among the work he conducted there were spectacular experiments in 1939–1940 with supersonic wind tunnels.
During World War II, in the period of the Italian Social Republic (or Salò Republic), three days after the Nazi Germany occupied Rome on 10 September 1943, Ferri bluffed his way back into the research facility at Guidonia, destroyed the vital equipment and filled a fruit crate with documents of his research before escaping underground. He secluded his wife and family near his home in Fiastra, in the Marche region of the Apennine Mountains (they later were moved on to an Adriatic Sea fishing village), and in October 1943, organized with his brother, Giuseppe Ferri, the Banda Fiastra band of partisans. For the next year he coordinated attacks of the region's anti-fascist bands using the Valle del Fiastrone Fiastra as a safe haven to return to and to receive Allied air drops.
He eventually made his way to Rome after it was liberated by the Allies, where he made contact with OSS agent Moe Berg and began to work with him translating key documents from the trunk, also passing on his knowledge of the achievements of German science during the war.
The facilities at Guidonia were destroyed in the course of the fighting. In 1944, Ferri was brought to the leading American research center in his field, the National Advisory Committee for Aeronautics in Langley, Virginia, where he continued as a major figure in his field.
In the immediate postwar period, he studied the use of a biconvex airfoil for high-speed aircraft and developed the Schlieren Flow Visualization method of predicting the impact of on aircraft wings. He then turned at length to the problem of atmospheric reentry, hypersonic thermofluids dynamics, as applied to the study of supersonic and hypersonic . He also conducted important studies in the fields of jet engine and aerodynamic heating of high speed aircraft. In all these areas, he made key contributions to the advancement of aerospace engineering. In 1956 he founded the General Applied Science Laboratory. Ferri was granted a patent for the 'Ferri scoop' jet engine inlet, which would be used on the XF-103, F-105, XF8U-3, and SSM-N-9 Regulus II cruise missile.
Ferri died in 1975 on Long Island, New York, United States.
