AVIC Advanced Heavy Lifter
The Advanced Heavy Lifter is a large helicopter project developed by Aviation Industry Corporation of China. Development In 2009, Avic projected a civil Advanced Heavy Lifter (AHL), likely also useful to the Chinese military. In 2014, the 6,000 kW (8,000 hp) Chinese WZ-20 was reportedly selected. In 2015, the joint project with Russian Helicopters grew to , with a seven blade main rotor and a ceiling. In 2016, Avic took control, leaving Russian Helicopters as a supplier, presumably of the transmission. In 2018, maximum weight grew again to . To power it, China will choose between the Ivchenko Progress D-136T manufactured by Ukraine's Motor-Sich, powering the current Mi-26, and the Russian PD-12V turboshaft developed from the Aviadvigatel PD-14 core for an updated Mi-26. After a $2 billion investment, AVIC hopes to produce 200. Design The takeoff weight and a MTOW allow for a internal payload or a external one. AVIC targets a range of 800 km (432 nm ...

Transport Helicopter
A military transport aircraft, military cargo aircraft or airlifter is a military-owned transport aircraft used to support military operations by airlifting troops and military equipment. Transport aircraft are crucial to maintaining supply lines to forward bases that are difficult to reach by ground or waterborne access, and can be used for both strategic and tactical missions. They are also often used for civilian emergency relief missions by transporting humanitarian aid. Air frames Fixed-wing Military transport aeroplanes are defined in terms of their range capability as strategic airlift or tactical airlift to reflect the needs of the land forces which they most often support. These roughly correspond to the commercial flight length distinctions: Eurocontrol defines short-haul routes as shorter than , long-haul routes as longer than and medium-haul between. The military glider is an unpowered tactical air transport which has been used in some campaigns to trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Main Rotor
On a helicopter, the 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mil Mi-26
The Mil Mi-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 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's largest and fastest production helicopter.
