S-64
The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter. It is the civil version of the United States Army's CH-54 Tarhe. It is currently produced as the S-64 Aircrane by Erickson Inc. Development Under Sikorsky The Sikorsky S-64 was designed as an enlarged version of the prototype ''flying crane'' helicopter, the Sikorsky S-60. The S-64 had a six-blade main rotor and was powered by two Pratt & Whitney T73, Pratt & Whitney JFTD12A turboshaft engines. The prototype S-64 first flew on 9 May 1962 and was followed by two further examples for evaluation by the German armed forces. The Germans did not place an order, but the United States Army placed an initial order for six S-64A helicopters (with the designation CH-54 Tarhe, YCH-54A Tarhe). Seven S-64E variants were built by Sikorsky for the civil market. Under Erickson Originally a Sikorsky Aircraft product, the type certificate and manufacturing rights were purchased from them by Erickson Air-Crane ...

Sikorsky CH-54 Tarhe
The Sikorsky CH-54 Tarhe is an American twin-engine heavy-lift helicopter designed by Sikorsky Aircraft for the United States Army. It is named after Tarhe, an 18th-century chief of the Wyandot Indian tribe whose nickname was "The Crane". The civil version is the Sikorsky S-64 Skycrane. Development Work on what would become the CH-54 can be traced back to Sikorsky's earlier activities with "sky-crane" helicopters, particularly the piston-engined Sikorsky S-60 of the late 1950s. Following the end of the Korean War, the United States Army sought to procure a successor to the Sikorsky CH-37 Mojave, an early piston-engined heavily lift helicopter; being aware of this need, Sikorsky were keen to fulfil it. The company was already working on the Sikorsky S-64 Skycrane, a civil-orientated heavy lift rotorcraft that was designed specifically for the purpose of carrying large payloads externally; the development of a military-configured derivative was viewed as a natural option ...

Sikorsky S-60
The Sikorsky S-60 helicopter, a prototype " flying crane", was derived from the S-56 in 1958. Proving to be underpowered, the development of the S-60 led to the larger, turbine-engined Sikorsky CH-54 Tarhe military transport helicopter, and its civil S-64 Skycrane variant, which were already on the drawing board by the time the sole example of the S-60 crashed on 3 April 1961. Design and development In 1958, Sikorsky began designing the S-60 as a prototype " flying crane" helicopter. The S-60 utilized the transmission, rotor system and piston engines from the CH-37/S-56.Donald 1997, p.?Harding 1997, p. 237. The fuselage of the S-60 was a simple "pod-and-boom" design with the engines mounted in side pods and long tailwheel-style landing gear that allowed it to straddle cargoes. The crew cabin was mounted in the nose, with aft-mounted controls for the co-pilot to use during loading and unloading operations. The S-60 had an automatic stabilization system to allow it to hover pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elvis (helicopter)
''Elvis'' is the nickname of Erickson S-64 Air-Crane, tail number ''OB-2081-P (N179AC)'', which has gained fame in Australia as a highly visible and valuable tool in bushfire suppression. The helicopter, which can hold of water or foam mix, has been brought out by the Victorian Government from the United States for each fire season since 2001-2002. The aircraft obtained its nickname due to the time that it spent working for the United States National Guard in Memphis, where singer Elvis Presley lived for most of his life. Erickson Air-Crane helitankers were first brought out to Victoria in December 1997. The first one, dubbed by locals as "Eric the Water Bomber" (N223AC), was used to fight a fire in Frankston and the Caledonia fire in the Alpine National Park, and was brought out again for subsequent fire seasons up to 2000-2001. On December 27, 2001 ''Elvis'', which had arrived in Melbourne, was immediately deployed to Bankstown, New South Wales to help with fire fighting ...

Aerial Crane
An aerial crane or flying crane is a helicopter used to lift heavy or awkward loads. As aerial cranes, helicopters carry loads connected to long cables or slings in order to place heavy equipment when other methods are not available or economically feasible, or when the job must be accomplished in remote or inaccessible areas, such as the tops of tall buildings or the top of a hill or mountain, far from the nearest road. Helicopters were first used as aerial cranes in the 1950s, but it was not until the 1960s that their popularity in construction and other industries began to catch on. The most consistent use of helicopters as aerial cranes is in the logging industry to lift large trees out of rugged terrain where vehicles are not able to reach, or where environmental concerns prohibit roadbuilding. These operations are referred to as longline because of the long, single sling line used to carry the load. History Bell 47 helicopters were the first, lightweight aerial cranes to be ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

CN Tower
The CN Tower (french: Tour CN) is a concrete communications and observation tower in downtown Toronto, Ontario, Canada. Built on the former Railway Lands, it was completed in 1976. Its name "CN" referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets prior to the company's privatization in 1995, it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for real estate development. The CN Tower held the record for the world's tallest free-standing structure for 32 years, from 1975 until 2007, when it was surpassed by the Burj Khalifa, and was the world's tallest tower until 2009 when it was surpassed by the Canton Tower. It is currently the ninth-tallest free-standing structure in the world and remains the tallest free-standing structure on land in the Western Hemisphere.
