Savoia-Marchetti SM.93
The Savoia-Marchetti SM.93 was an Italian dive bomber designed and produced in Italy from 1943. Design The SM.93 was an all-wood single-engined low-wing monoplane with retractable undercarriage. The fuselage had a monocoque structure, with a single fin and low-set tailplane. The crew of two were accommodated under a long greenhouse-style canopy, with the pilot lying in a prone position above the rear of the engine, a Daimler-Benz DB 605A liquid-cooled V12 engine, while the gunner/radio-operator sat facing rearwards on a conventional seat. The two-spar wings were in three parts with the inner wings sharply tapered to the join, outboard of the landing gear attachments, and the outer wings moderately tapered to the rounded wingtips.''Air International'' August 1982, p. 98. The prone position for the pilot was intended to enable the pilot to resist the onset of g-induced loss of consciousness, but the position was uncomfortable for normal flight and severely limited the rearwards v ...

Italian Social Republic
The Italian Social Republic (, ; RSI; , ), known prior to December 1943 as the National Republican State of Italy (; SNRI), but more popularly known as the Republic of Salò (, ), was a List of World War II puppet states#Germany, German puppet state and Fascism, fascist rump state with limited diplomatic recognition that was created during the latter part of World War II. It existed from the beginning of the Operation Achse, German occupation of Italy in September 1943 until the Surrender of Caserta, surrender of Axis troops in Italy in May 1945. The German occupation triggered widespread Italian resistance movement, national resistance against it and the Italian Social Republic, leading to the Italian Civil War. The Italian Social Republic was the second and last incarnation of the Italian fascism, Italian Fascist state, led by the Italian dictator Benito Mussolini and his reformed Abolition of monarchy, anti-monarchist Republican Fascist Party. The newly founded state declar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1940s Italian Attack Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Savoia-Marchetti Aircraft
SIAI-Marchetti was an Italian aircraft manufacturer primarily active during the interwar period. History The original company was founded during 1915 as SIAI (''Società Idrovolanti Alta Italia'' – Seaplane Company of Upper Italy). As suggested by its name, the firm initially specialised in the manufacture of seaplanes, the vast majority of which were intended for the Italian armed forces. Perhaps its most prominent early aircraft was the SIAI S.16, a seaplane that had been configured to perform both aerial reconnaissance and bomber roles, but also proved itself quite capable of long-distance flights. During 1925, Italian aviator Francesco de Pinedo of the '' Regia Aeronautica'' (Italian Royal Air Force) used an SIAI S.16''ter'' he named ''Genariello'' for a record-setting flight from Rome to Australia and Tokyo to demonstrate his idea that seaplanes were superior to landplanes for long-distance flights. Having departed Rome on 21 April, Pinedo and his mechanic, Ernesto Campan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breda-SAFAT Machine Gun
Breda-SAFAT (''Società Italiana Ernesto Breda per Costruzioni Meccaniche / Breda Meccanica Bresciana'' - ''Società Anonima Fabbrica Armi Torino'') was an Italian weapons manufacturer of the 1930s and 1940s that designed and produced a range of machine-guns and cannon primarily for use in aircraft. Based on the M1919 Browning machine gun, the Italian guns were chambered to fire indigenous ammunition with and calibres, predominantly ball, tracer for the 7.7mm, including high explosive incendiary tracer (HEI-T) (filled with 0.8 grams of PETN), or armour-piercing (AP) for the 12.7mm. Design and development During the 1930s both Breda and SAFAT (a division of FIAT) were given the task of producing designs for a new range of machine-guns for use in aircraft of the Regia Aeronautica, the offering from Breda being preferred. FIAT contested the decision but lost, resulting in the sale of SAFAT to Breda to form Breda-SAFAT. Despite the aim of producing an airborne machine-gun equal ...

MG 151 Cannon
The ''Maschinengewehr'' (MG) 151 is a belt-fed autocannon for aircraft use, developed in Nazi Germany from 1934 to 1940 and produced by Waffenfabrik Mauser during World War II. It was originally produced in 15.1 mm caliber from 1940, with a 15×96mm cartridge, but due to demand for higher effect against aircraft, especially with the introduction of mine shells for the 20 mm MG-FF/M aircraft cannon, the design was rechambered to 20 mm caliber in 1941, using a newly developed 20×82mm cartridge which traded projectile velocity for explosive power. The initial 15 mm variant then became known as the MG 151/15, with the new 20 mm variant becoming the MG 151/20. The MG 151/20 cannon was widely used on German Luftwaffe combat aircraft throughout World War II, mainly as offensive armament, but also seeing some use as defensive guns. Existing MG 151/15 guns saw use as aircraft armament throughout the war, albeit more limited compared to the MG 151/20, but also as ...

Daimler-Benz DB 605A
The Daimler-Benz DB 605 is a German aircraft engine built during World War II. Developed from the DB 601, the DB 605 was used from 1942 to 1945 in the Messerschmitt Bf 109 fighter, and the Bf 110 and Me 210C heavy fighters. The DB 610, a pair of DB 605s geared to turn a single output shaft that replaced the similar DB 606, was used in the A-3 and all A-5 variants of Germany's only operational heavy bomber, the Heinkel He 177A. License-built versions of the DB 605 were used in the Macchi C.205, Fiat G.55, Reggiane 2005 and some other Italian aircraft. It was also used in the Swedish SAAB B 18B and initially in the pusher-design SAAB J 21. Approximately 42,400 DB 605s of all kinds were built. Design and development The primary differences between the 605 and 601 were greater displacement, higher revolutions, higher compression ratio and a more powerful supercharger. Engineers determined that the cylinders could be bored out to a larger diameter without seriously affecting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V12 Engine
A V12 engine is a twelve-Cylinder (engine), cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of six cylinders are arranged in a V engine, V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in Boat racing, racing boats. Due to the balanced nature of the engine and the smooth delivery of Engine power, power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, after which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars.
