Mil Mi-26
The Mil Mi-26 (russian: link=no, Миль Ми-26, NATO reporting name: Halo) is a Soviet/Russian heavy transport helicopter. Its product code is ''Izdeliye 90''. Operated by both military and civilian operators, it is the largest and most powerful helicopter to have gone into serial production. Design and development Following the incomplete development of the heavier Mil Mi-12 (prototypes known as Mil V-12) in the early 1970s, work began on a new heavy-lift helicopter, designated as the ''Izdeliye 90'' ("Project 90") and later allocated designation ''Mi-26''. The new design was required to have an empty weight less than half its maximum takeoff weight. The helicopter was designed by Marat Tishchenko, protégé of Mikhail Mil, founder of the OKB-329 design bureau. The Mi-26 was designed to replace earlier Mi-6 and Mi-12 heavy lift helicopters and act as a heavy-lift helicopter for military and civil use, having twice the cabin space and payload of the Mi-6, then the world ...

Maximum Takeoff Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or the length of the runway to be used for takeoff or landing. Maximum permissible takeoff weight or "regulated takeoff weight", varies according to flap setting, altitude, air temperature, length of runway and other factors. It is different from one takeoff to the next, but can never be higher than the MTOW. Certification standards Certification standards applicable to the airworthiness of an aircraft contain many requirements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

MD Helicopters MD 500
The MD Helicopters MD 500 series is an American family of light utility civilian and military helicopters. The MD 500 was developed from the Hughes 500, a civilian version of the US Army's OH-6A Cayuse/Loach. The series currently includes the MD 500E, MD 520N, and MD 530F. The MD 500 was initially produced by Hughes Helicopters as the ''Hughes 500''. Since being introduced in 1967, numerous models have been produced, often featuring a more powerful engine or a five-bladed main rotor in place of the original four-blade counterpart. The MD 500 has been commonly used for utility work, particularly the ''MD 530F''; it has also proven to be popular with law enforcement agencies. Production of the type was continued into the twenty-first century by Hughes' successor companies, McDonnell Douglas Helicopter Systems, and subsequently MD Helicopters. While the MD 500 series has been largely operated by civil customers, it has occasionally seen military use, even to the extent of performi ...

Payload
Payload is the object or the entity which is being carried by an aircraft or launch vehicle. Sometimes payload also refers to the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight. Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally carried, is also considered part of the payload. In a commercial context (i.e., an airline or air freight carrier), payload may refer only to revenue-generating cargo or paying passengers. A payload of ordnance carried by a combat aircraft is sometimes alternatively referred to as the aircraft's warload. For a rocket, the payload can be a satellite, space probe, or spacecraft carrying humans, animals, or cargo. For a ballistic missile, the payload is one or more warheads and related systems; their total weight is referred to as the throw-weight. Th ...

Helicopter Rotor
A helicopter main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. Each main rotor is mounted on a vertical mast over the top of the helicopter, as opposed to a helicopter tail rotor, which connects through a combination of drive shaft(s) and gearboxes along the tail boom. The blade pitch is typically controlled by the pilot using the helicopter flight controls. Helicopters are one example of rotary-wing aircraft (rotorcraft). The name is derived from the Greek words ''helix'', helik-, meaning spiral; and ''pteron'' meaning wing. Design principles Overview The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. At the top of the mast i ...

Ilyushin Il-76
The Ilyushin Il-76 (russian: Илью́шин Ил-76; NATO reporting name: Candid) is a multi-purpose, fixed-wing, four-engine turbofan strategic airlifter designed by the Soviet Union's Ilyushin design bureau. It was first planned as a commercial freighter in 1967, as a replacement for the Antonov An-12. It was designed to deliver heavy machinery to remote, poorly served areas. Military versions of the Il-76 have been widely used in Europe, Asia and Africa, including use as an aerial refueling tanker or command center. The Il-76 has seen extensive service as a commercial freighter for ramp-delivered cargo, especially for outsized or heavy items unable to be otherwise carried. It has also been used as an emergency response transport for civilian evacuations as well as for humanitarian aid and disaster relief around the world. Due to its ability to operate from unpaved runways, it has been useful in undeveloped areas. Specialized models have also been produced for aerial fir ...

Antonov An-22
The Antonov An-22 "Antei" (, ''An-22 Antej''; English ''Antaeus'') (NATO reporting name "Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first wide-body transport aircraft and remains the world's largest turboprop-powered aircraft to date. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Thereafter, the model saw extensive use in major military and humanitarian airlifts for the Soviet Union, and is still in service with the Russian Air Force. Design and development In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kyiv, U ...

Mil Mi-6
The Mil Mi-6 (NATO reporting name Hook), given the article number ''izdeliye 50'' and company designation V-6, is a Soviet/Russian heavy transport helicopter that was designed by the Mil design bureau. It was built in large numbers for both military and civil roles and used to be the largest helicopter in production until Mil Mi-26 was put in production in 1980. Design and development The Mi-6 resulted from a joint civil-military requirement for a very large vertical-lift aircraft, which could be used to add mobility in military operations as well as assist in the exploration and development of the expansive central and eastern regions of the USSR. Flown for the first time on 5 June 1957, the Mi-6 was the first Soviet turboshaft-powered production helicopter. The R-7 gearbox and rotor head developed for the project have a combined weight of 3200 kg, which is greater than the two turboshaft engines. Variable-incidence winglets were first mounted on the craft's sides in 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
