Originally powered by a radial engine and designated Ca 335
Maestrale (Mistral), this two-seat fighter/reconnaissance monoplane was
designed in 1938 at Ponte San Pietro, but after the construction of the first
prototype in 1939, the manufacturing license was sold to S.A.B.C.A. (Societe
Anonyme Beige de Constructions Aeronautiques) of Brussels, Belgium. Powered by
an 860 h.p. Hispano-Suiza 12 Ycrs twelve-cylinder vee liquid-cooled engine and
designated S.47, the Belgian version was to have been built quantity, but this
was prevented by the overwhelming German invasion. Armament comprised one
20-mm. cannon firing through the airscrew hub, two 7.7-mm. Browning machine
guns in the wings, and one flexible hand-held gun in the rear cockpit. Empty
weight was 4950 lb. and loaded weight varied from 6545 lb. (fighter) and 7128
lb. (reconnaissance) to 7370 lb. for attack.
Performance included a maximum speed of 311 m.p.h. at 13,780
ft., a service ceiling of 32,800 ft., and a range of 978 miles, or a duration
of 2 hrs. (fighter) to 4 hrs. 30 min. (reconnaissance). The S.47 fighter
climbed to 6560 ft. in 3 min. 30 sec., to 13,120 ft. in 7 min. 20 sec., and to
19,680 ft. in 12 min. 20 sec. Dimensions were: span 43 ft. 3 in., length 34 ft.
9 in., height 10 ft. 6 in., and wing area 254 sq. ft.
