Macchi MC.207
The Macchi C.205 ''Veltro'' ( it, Greyhound) (also known as MC.205, "MC" standing for "Macchi Castoldi") was an Italian World War II fighter aircraft built by the Aeronautica Macchi. Along with the Reggiane Re.2005 and Fiat G.55, the Macchi C.205 was one of the three "''Serie'' 5" Italian fighters built around the powerful Daimler-Benz DB 605 engine. The C.205 was a development of the earlier C.202 ''Folgore''. With a top speed of some and equipped with a pair of 20 mm cannon as well as 12.7 mm Breda machine guns, the Macchi C.205 ''Veltro'' was highly respected by Allied and Axis pilots alike. Widely regarded as one of the best Italian aircraft of World War II, it proved to be extremely effective, destroying a large number of Allied bombers.Mondey 2006, p. 256. The Macchi C. 205 proved capable of meeting fighters such as the North American P-51D Mustang on equal terms, which encouraged the ''Luftwaffe'' to use a number of these aircraft to equip one ''Gruppe''.Mondey ...

Daimler-Benz DB 605
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] |
Ground-attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se'', although fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armistice Between Italy And Allied Armed Forces
The Armistice of Cassibile was an armistice signed on 3 September 1943 and made public on 8 September between the Kingdom of Italy and the Allies during World War II. It was signed by Major General Walter Bedell Smith for the Allies and Brigade General Giuseppe Castellano for Italy at a conference of generals from both sides in an Allied military camp at Cassibile, in Sicily, which had recently been occupied by the Allies. The armistice was approved by both the Italian King Victor Emmanuel III and Marshal Badoglio, the Prime Minister of Italy at the time. Germany moved rapidly by freeing Benito Mussolini (12 September) and attacking Italian forces in Italy (8–19 September), southern France and the Balkans. The Italian forces were quickly defeated, and most of Italy was occupied by German troops, who established a puppet state, the Italian Social Republic. The king, the Italian government, and most of the navy escaped to territories occupied by the Allies. Background Fo ... [...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 MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II. Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe Fighter aircraft, fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft. Salvaged guns saw post-war use by other nations. Development and wartime history (MG 151/20) The pre-war German doctrine for arming single-engine fighter aircraft mirrored that of the French. This doctrine favoured a powerful autocannon mounted between the cylinder banks of a V engine and firing through the propeller hub, known as a ''moteur-canon'' in French (from its first use with the Hispano-Suiza 8#Variants, Hispano-Suiza HS.8C engine in World War I, on the SPAD S.XII) and by the cognate ''Motorkanone'' in German by the 1930s. The weapon preferred by the French in this role was the most powerful 20mm Oerlikon of the time, namely the Oerlikon 20 mm cannon, FFS model, b ...

Wing Loading
In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. An aircraft or animal with a low wing loading has a larger wing area relative to its mass, as compared to one with a high wing loading. The faster an aircraft flies, the more lift can be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. Consequently, faster aircraft generally have higher wing loadings than slower aircraft. This increased wing loading also increases takeoff and landing distances. A higher wing loading also decreases maneuverability. The same constraints apply to winged biological organisms. Range of wing loadings Effect on performance Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Benz DB 601
The Daimler-Benz DB 601 was a German aircraft engine built during World War II. It was a liquid-cooled inverted V12 engine, V12, and powered the Messerschmitt Bf 109, Messerschmitt Bf 110, and many others. Approximately 19,000 601's were produced before it was replaced by the improved Daimler-Benz DB 605 in 1942. The DB 601 was basically an improved Daimler-Benz DB 600, DB 600 with gasoline direct injection, direct fuel injection. Fuel injection required power to be taken off the drive shaft, but in return, improved low-RPM performance significantly and provided aerobatic performance in maneuvers where early versions of carburetor, carburated engines like the British Rolls-Royce Merlin would lose power when the carburetor float bowl ran dry. The 601's fuel injection provided a significant boost in performance which its competitor, the Junkers Jumo 210, did not match for some time. By the time the fuel-injected 211 arrived, the 601 had already cemented its place as the engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...
