Caproni CH.1
The Caproni CH.1 was a single-seat biplane fighter, a single example of which was produced as a prototype in Italy in 1935. Design Antonio Chiodi began design work on a new single-seat fighter in 1934 as a private venture of the Caproni company. He designed the Caproni CH.1—"CH" standing for "Chiodi"—an aerodynamically clean single-bay biplane of all-metal construction, with fabric skin and wings of equal span. The aircraft had spatted landing gear. The cockpit was enclosed, with a canopy that opened by sliding to the rear.Green and Swanborough, p. 108. Chiodi intended the CH.1 to be powered by a Gnome-Rhône 14Kfs Mistral Major 14-cylinder radial engine, rated at at 4,750 meters (15,584 feet), but instead the aircraft was constructed with a Piaggio Stella P.IX R.C.40 nine-cylinder radial rated at at 4,000 meters (13,123 feet) driving a three-bladed, variable-pitch propeller. The CH.1s proposed armament was two fixed forward-firing 7.7-millimeter (0.303-inch) Breda-SA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

1930s Italian Fighter Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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 * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace.

Caproni Aircraft
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable-pitch
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guidonia Montecelio
Guidonia Montecelio (), commonly known as Guidonia, is a town and ''comune'' in the Metropolitan City of Rome Capital, Lazio, central Italy. Geography The municipality of Guidonia Montecelio, formed by the main towns of Guidonia and Montecelio, lies to the north-east of Rome, some kilometres from the Grande Raccordo Anulare - a ring-shaped motorway which forms a circle around the capital. The terrain of Guidonia Montecelio is mainly flat, and the community lies in between the Via Nomentana and the Via Tiburtina. It borders with Fonte Nuova, Marcellina, Palombara Sabina, Rome, San Polo dei Cavalieri, Sant'Angelo Romano and Tivoli. The hamlets (''frazioni'') are Albuccione, Bivio di Guidonia, Colle Fiorito, Colleverde, La Botte, Marco Simone, Montecelio, Pichini, Setteville, Setteville Nord, Villalba and Villanova. History Montecelio was founded in 998 as a fortified ''castrum'' (''Castrum Monticellorum''). In 1915 the ''Regio Esercito'' (Italian Royal Army) built a major milita ...

Regia Aeronautica
The Italian Royal Air Force (''Regia Aeronautica Italiana'') was the name of the air force of the Kingdom of Italy. It was established as a service independent of the Royal Italian Army from 1923 until 1946. In 1946, the monarchy was abolished and the Kingdom of Italy became the Italian Republic, whereupon the name of the air force changed to Aeronautica Militare. History Beginnings At the beginning of the twentieth century, Italy was at the forefront of aerial warfare: during the colonization of Libya in 1911, it made the first reconnaissance flight in history on 23 October, and the first ever bombing raid on 1 November. During World War I, the Italian ''Corpo Aeronautico Militare'', then still part of the ''Regio Esercito'' (Royal Army), operated a mix of French fighters and locally built bombers, notably the gigantic Caproni aircraft. The ''Regia Marina'' (Royal Navy) had its own air arm, operating locally built flying boats. Founding of the ''Regia Aeronautica'' ...

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 ...

Variable-pitch Propeller (aeronautics)
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed (RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is st ...
