Ka-126
The Kamov Ka-26 (NATO reporting name Hoodlum) is a Soviet light utility helicopter with co-axial rotors. Development The Ka-26 entered production in 1969 and 816 were built. A variant with a single turboshaft engine is the Ka-126. A twin turboshaft-powered version is the Ka-226. (All the Ka-26/126/128/226 variants are code-named by NATO as "Hoodlum"). Design The fuselage of the Ka-26 consists of a fixed, bubble-shaped cockpit containing the pilot and co-pilot, plus a removable, variable box available in medevac, passenger-carrying and crop duster versions. The helicopter can fly with or without the box attached for flexibility. It is powered by two 325 hp (239 kW) Vedeneyev M-14V-26 radial engines mounted in outboard nacelles. The Ka-26 is small enough to land on a large truck bed. The reciprocating engines are more responsive than turboshaft engines, but require more maintenance. It runs mostly at 95% power in crop dusting with usually excess payload, leaving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Industria Aeronautică Română
Industria Aeronautică Română (IAR) (now IAR S.A. Brașov) or Romanian Aeronautic Industry in English, is a Romanian aerospace manufacturer. It is based in Ghimbav, near Brașov, Romania. IAR was founded in 1925 with the aid of the Romanian government, which sought to reduce reliance on foreign companies to supply the Royal Romanian Air Force with aircraft and associated equipment. In addition to its designs, the company built numerous foreign-designed aircraft under license as well. IAR produced a low-wing all-metal monoplane, the IAR 80, during the Second World War; this combat aircraft was extensively used by the nation during the conflict. During the Cold War era, the company branched out into helicopters, securing licensing agreements with France for their designs in the field, leading to the IAR 316 and IAR 330. In 2000, IAR partnered with the multinational helicopter manufacturer Eurocopter Group to create the ''Eurocopter Romania'' joint venture company. Presently, the ...

Coaxial Rotors
Coaxial rotors or coax rotors are a pair of helicopter rotors mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau. History The idea of coaxial rotors originates with Mikhail Lomonosov. He had developed a small helicopter model with coaxial rotors in July 1754 and demonstrated it to the Russian Academy of Sciences. In 1859, the British Patent Office awarded the first helicopter patent to Henry Bright for his coaxial design. From this point, coaxial helicopters developed into fully operational machines as we know them today. Two pioneering helicopters, the Corradino D'Ascanio-built "D'AT3" of 1930, and the generally more successful French mid-1930s ''Gyroplane Laboratoire'', both used coaxial rotor systems for flight. Design considerations Having two coaxial sets of rotors provides sym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airborne Forces
Airborne forces, airborne troops, or airborne infantry are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop or air assault. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers. The main advantage of airborne forces is their ability to be deployed into combat zones without land passage, as long as the airspace is accessible. Formations of airborne forces are limited only by the number and size of their transport aircraft; a sizeable force can appear "out of the sky" behind enemy lines in merely hours if not minutes, an action known as ''vertical envelopment''. Airborne forces typically lack enough supplies for prolonged combat, so they are utilized for establishing an airhead to bring in larger forces before carrying out other combat objectives. Some infantry fighting vehicles have also been modified for paradropping with infantry to provide heavier firepower. Due t ...

Mil Mi-2
The Mil Mi-2 (NATO reporting name Hoplite) is a small, three rotor blade Soviet-designed multi-purpose helicopter developed by the Mil Moscow Helicopter Plant designed in the early 1960s, and produced exclusively by WSK "PZL-Świdnik" in Poland. Design and development The Mi-2 was produced exclusively in Poland, in the WSK "PZL-Świdnik" factory in Świdnik. The first production helicopter in the Soviet Union was the Mil Mi-1, modelled along the lines of the S-51 and Bristol Sycamore and flown by Mikhail Mil's bureau in September 1948. During the 1950s it became evident, and confirmed by American and French development, that helicopters could be greatly improved with turbine engines. S. P. Isotov developed the GTD-350 engine and Mil used two of these in the far superior Mi-2. The twin shaft-turbine engines used in the Mi-2 develop 40% more power than the Mi-1's piston engines, for barely half the engine weight, with the result that the payload was more than doubled. The Mi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NOTAR
NOTAR ("no tail rotor") is a helicopter system which avoids the use of a tail rotor. It was developed by McDonnell Douglas Helicopter Systems (through their acquisition of Hughes Helicopters). The system uses a fan inside the tail boom to build a high volume of low-pressure air, which exits through two slots and creates a boundary layer flow of air along the tailboom utilizing the Coandă effect. The boundary layer changes the direction of airflow around the tailboom, creating thrust opposite the motion imparted to the fuselage by the torque effect of the main rotor. Directional yaw control is gained through a vented, rotating drum at the end of the tailboom, called the direct jet thruster. Advocates of NOTAR believe the system offers quieter and safer operation over a traditional tail rotor. Development The use of directed air to provide anti-torque control had been tested as early as 1945 in the British Cierva W.9. During 1957, a Spanish prototype designed and built by Aerot ...
