ROS-Aeroprogress T-101 Grach
The light multipurpose aircraft T-101 "Grach" or "Rook" in English, was based on the An-2 biplane and planned as a replacement for it. The design is focused on low cost, high reliability, and operating from unprepared airfields. The T-101 can carry 10 passengers, or transport 1600 kg of cargo. It can be used for agricultural, patrol, aerial photography, search and rescue, airborne and other utility functions. The T-101 has a strut-braced high-wing, fixed landing gear Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, s ... with tail wheel and a single engine in the nose.

Biplane
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 als ...

Aerial Photography
Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other flight, airborne platforms. When taking motion pictures, it is also known as aerial videography. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloon (aircraft), balloons, blimps and dirigibles, rockets, pigeon photography, pigeons, kite aerial photography, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remote operation, remotely operated or triggered automatically. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and Earth surface, surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Elevated photography can also produce b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. 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 Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Tail Wheel
The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso. In vertebrate animals that evolved to lose their tails (e.g. frogs and hominid primates), the coccyx is the homologous vestigial of the tail. While tails are primarily considered a feature of vertebrates, some invertebrates such as scorpions and springtails, as well as snails and slugs, have tail-like appendages that are also referred to as tails. Tail-shaped objects are sometimes referred to as "caudate" (e.g. caudate lobe, caudate nucleus), and the body part associated with or proximal to the tail are given the adjective "caudal" (which is considered a more precise anatomical terminology). Function Animal tails are used in a variety of ways. They provide a source of thrust for aquatic locomotion for fish, cetaceans and crocodilians and other forms of marine life. Terrestrial species of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glushenkov TVD-10B
The Omsk Engine Design Bureau (along OMO named after Baranov) is an aero engine design bureau. It was originally situated in Moscow in the Soviet Union, but was evacuated in 1941. Operations were moved to a "site of farm machinery" . The Bureau returned to Moscow and became independent on 5 July 1947 and was renamed "OKB-20" . The bureau absorbed OKB-29 in 1963 and in 1966 was renamed ''Mashinostoitel'noe KB'' (MKB). Since 1994, it has been known as ''Omskoe mashinstroitel'noe KB'' (or ''OMKB'') . Although it has had many chief designers and directors, many of the engines from this bureau are known by the name Glushenkov, named for V.A. Glushenkov, a designer from 1963. In soviet times, some engineers from OMKB and OMO Baranov Polyot left to Zaporozhe Ivchenko Progress (Motor Sich) to manufacture helicopter engine turboshafts, turboprops, turbojets, turbofans and gas turbines. Due to forced soviet decentralization and partly due to medal achievements, engine dimensions and relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Broadcast Information Service
The Foreign Broadcast Information Service (FBIS) was an open source intelligence component of the Central Intelligence Agency's Directorate of Science and Technology. It monitored, translated, and disseminated within the U.S. government openly available news and information from media sources outside the United States. Its headquarters was in Rosslyn, later Reston, Virginia, and it maintained approximately 20 monitoring stations worldwide. In November 2005, it was announced that FBIS would become the newly formed Open Source Center, tasked with the collection and analysis of publicly available intelligence. History On 26 February 1941, President Roosevelt directed that $150,000 be allocated for creation of the Foreign Broadcast Monitoring Service (FBMS) under the authority of the Federal Communications Commission. The mandate of the FBMS was to record, translate, transcribe and analyze shortwave propaganda radio programs that were being beamed at the United States by the Axi ...

1990s Soviet And Russian Civil Utility Aircraft
Year 199 ( CXCIX) was a common year starting on Monday of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 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.

High-wing Aircraft
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 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 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 an ...
