M.7


Летающая лодка-истребитель М.7 стала развитием самолета М.5, но для увеличения скорости и улучшения маневренности в ее конструкцию были внесены значительные изменения. Как и последние самолеты М.5, новая машина оснащалась двигателем "Изота-Фраскини" V-6B (250 л. с.). Однако самолет имел новую конструкцию лодки. Она получила слабокилеватый редан и приподнятую хвостовую балку. Верхнее крыло стало почти на 2 м короче. Хорда крыльев, особенно нижнего, была значительно увеличена. Это позволило, сохранив ту же несущую поверхность, улучшить маневренность машины. Подкрыльевые поплавки, в отличие от М.5 (имевшей поплавки, выполненные заподлицо с крылом), устанавливались на коротких стойках. Удачная машина была пущена в серию, но принять участие в боевых действиях ей практически не пришлось - война закончилась.

MACCHI M.7 Italy

  The M.7 was essentially a progressive development of the M.5 and entered flight testing early in 1918. Powered by a 247 bhp Isotta-Fraschini V.6 engine, the M.7 was of wooden construction similar to that of its predecessors and carried an armament of twin 7,7-mm Vickers guns. It featured a simplified wing cellule, with paired, splayed interplane struts. Series production was initiated, but orders were curtailed with the end of hostilities, 11 being completed of which three were delivered before the end of World War I. Two each were purchased by Argentina and Sweden in 1919, and three were procured by Brazil in 1921. Despite the cancellation of orders for the Regia Marina, development of the basic design continued, one example being fitted with a hull of increased fineness ratio, and two were modified to M.7 bis standard for participation in the 1921 Schneider Trophy contest. The M.7 bis had wing span and area reduced to 25 ft 5 in (7,75 m) and 256.19 sq ft (23,80 m2) respectively, and captured the Trophy in August 1921 with an average speed of 117.75 mph (189,50 km/h) in a contest in which the Macchi 'boat was, in fact, the only participant.

Max speed, 130 mph (210 km/h).
Time to 16,405 ft (5000 m), 23 min.
Endurance, 3.66 hrs.
Empty weight, 1,708 lb (775 kg).
Loaded weight, 2,381 lb (1080 kg).
Span, 32 ft 7 3/4 in (9,95 m).
Length, 26 ft 6 9/10 in (8,10 m).
Height, 9 ft 8 1/8 in (2,95 m).
Wing area, 286.33 sq ft (26,60 m2).


MACCHI M.7TER Italy

  Only nominally a development of the wartime M.7 fighter, the M.7 ter, flown as a prototype in October 1923, was virtually a new design, with a redesigned hull, a revised and lighter structure and wings of revised planform and reduced area. Primarily of wooden construction, with a 247 bhp Isotta-Fraschini V.6 engine and twin-Vickers gun armament, the M.7 ter was ordered into series production to re-equip the Squadriglie Caccia Marittima as the M.7terA, the M.7terAR having folding wings for operation from the seaplane carrier Miraglia. The M.7terB was powered by a 480 hp Lorraine 12Db engine, and, in 1927, the Societa Aeronautica Italiana re-engined 14 M.7terA 'boats with the 250 hp Isotta-Fraschini Semi-Asso engine. Total production of the M.7 ter exceeded 100 machines and these equipped all six Squadriglie Caccia Marittima by 1925 at the principal Italian naval bases, these eventually forming the 80° Gruppo. Eighty-three were in service in 1927, including 29 of the folding-wing AR version, the last being withdrawn from first line service in 1930.

Max speed, 129 mph (208 km/h).
Time to 3,280 ft (1000 m), 2.75 min.
Endurance, 3 hrs.
Empty weight, 1,775 lb (805 kg).
Loaded weight, 2,381 lb (1 080 kg).
Span, 32 ft 7 3/4 in (9,95 m).
Length, 29 ft 0 1/3 in (8,85 m).
Height, 9 ft 8 9/10 in (2,97 m).
Wing area, 252.96 sqft (23,50 m2).

A further development of the M.5, the M.7 continued the Macchi fighter flying boat formula.
