Yak-12
The Yakovlev Yak-12 (russian: Яковлев Як-12, also transcribed as Jak-12, NATO reporting name: "Creek") is a light multirole STOL aircraft used by the Soviet Air Force, Soviet civilian aviation and other countries from 1947 onwards. Design and development The Yak-12 was designed by Yakovlev's team to meet a requirement of the Soviet Air Force of 1944 for a new liaison and utility plane, to replace the obsolete Po-2 biplane. It was also meant to be used in civil aviation as a successor to Yakovlev's AIR-6 of 1934, built in a relatively small series. Yakovlev's first proposal was a four-place high-wing aircraft, the Yak-10 (first named Yak-14), built in January 1945. It won the competition with a low-wing Yak-13, based on the same fuselage, and a series of 40 Yak-10s were produced,Gunston 1995, pp. 468–469. powered with a 108 kW (145 hp) Shvetsov M-11M radial. In 1947, Yakovlev developed a new aircraft to replace the Yak-10. This was fitted with a more pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PZL-101 Gawron
The PZL-101 Gawron (''rook'') is a Polish agricultural and utility aircraft designed and built by WSK-Okęcie (later PZL "Warszawa-Okęcie"). Design and development The PZL-101 was a development of the Yakovlev Yak-12M, manufactured in Poland under licence from 1956. The main goal was to create an agricultural aircraft with increased useful load. Works were carried out by a team led by Stanisław Lassota. Behind two crew seats there was installed a container for 500 kg of chemicals, with a "hump" above a fuselage. Because a center of gravity moved rearwards, the plane was fitted with new, swept wings, with significant vertical end plates to improve air flow. Later, in most of the aircraft they were removed, because they increased side surface, making landing very tricky in crosswind. Main landing gear was also shifted rearwards, comparing with Yak-12. Equipment was also simplified and lightened to increase useful load, e.g. the right door was removed. The first prototype ...

Polish Aviation Museum
The Polish Aviation Museum ( pl, Muzeum Lotnictwa Polskiego w Krakowie) is a large museum of historic aircraft and aircraft engines in Kraków, Poland. It is located at the site of the no-longer functional Kraków-Rakowice-Czyżyny Airport. This airfield, established by Austria-Hungary in 1912, is one of the oldest in the world. The museum opened in 1964, after the airfield closed in 1963. Has been scored as eighth world's best aviation museum by CNN. For the first half century of its existence the museum used four hangars of the former airfield to display its exhibits. These buildings were not originally designed for this purpose and suffered from various inadequacies, notably insufficient heating in winter. The situation improved when a new main building for the museum opened on 18 September 2010. Collection The collection consists of over 200 aircraft as of 2005. Several of the aircraft displayed are unique on the world scale, including sailplanes and some 100 ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shvetsov M-11
The Shvetsov M-11 is a five-cylinder air-cooled radial aircraft engine produced in the Soviet Union between 1923 and 1952.Gunston 1989, p.158. Design and development The Shvetsov M-11 was designed under a 1923 competition in the Soviet Union for a new engine to power trainer aircraft. It is a single-row five-cylinder air-cooled radial piston engine with aluminum cylinder heads. Like the American Kinner B-5 5-cylinder radial of similar size, the M-11 had individual camshafts for each cylinder, operating the pushrods, rather than a single central cam ring. The initial versions of the M-11 suffered from a short service life of only 50 hours. The basic M-11 engine had a power output of 100 hp (73 kW), the newer M-11D variant was higher at 125 hp (92 kW). The ultimate version, M-11FR, introduced in 1946, increased power output to 160 hp at 1,900 rpm on takeoff and 140 hp at cruise and had provisions for a variable-pitch propeller, accessory drive (for vacu ...

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 ...

1945 In Aviation
This is a list of aviation-related events from 1945: Events * The probe-and-drogue aerial refueling system, in which the tanker aircraft trails a hose with a stabilizing conical drogue at its end which mates to a fixed probe mounted on the receiving aircraft, is perfected. It is superior to and replaces the looped-hose system which had been in use since 1934, and it remains in use today. * With its runways repaired Leningrad′s Shosseynaya Airport (the future Pulkovo Airport) reopens; it had been closed since 1941 because of the proximity of German forces during the Siege of Leningrad. Only cargo and mail flights will take place until February 1948, when scheduled passenger service finally will resume. * Iraqi Airways is founded. It will begin flight operations in January 1946. January * January 1 – The ''Luftwaffe'' targets Allied airfields in Europe in "Operation Bodenplatte", occurring during the German withdrawal from the Battle of the Bulge. * January 2 ** Japanese a ...

Air Ambulance
Air medical services is a comprehensive term covering the use of air transportation, aeroplane or helicopter, to move patients to and from healthcare facilities and accident scenes. Personnel provide comprehensive prehospital and emergency and critical care to all types of patients during aeromedical evacuation or rescue operations aboard helicopter and propeller aircraft or jet aircraft. The use of air transport to provide medical evacuation on the battlefield dates to World War I, but its role was expanded dramatically during the Korean and Vietnam wars. Later on, aircraft began to be used for the civilian emergency medical services. Helicopters can bring specialist care to the scene and transport patients to specialist hospitals, especially for major trauma cases. Fixed-wing aircraft are used for long-distance transport. In some remote areas, air medical services deliver non-emergency healthcare such as general practitioner appointments. An example of this is the Royal Flyin ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

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.
