Sikorsky S-64 Skycrane is an American high-capacity transport helicopter manufactured by aircraft manufacturers Sikorsky Aircraft and Erickson Air-Crane since 1962.
The development of this aircraft was initially conducted exclusively by the aircraft manufacturer Sikorsky Aircraft based on the US military helicopter Sikorsky CH-54 Tarhe, while the appearance of the aircraft remained virtually unchanged, however, the functionality of this helicopter was significantly increased.
Due to the wide functional capabilities of the Sikorsky S-64 Skycrane helicopter, it is used in a wide variety of industries, including construction, transportation of bulky goods weighing up to 10325 kilograms, when installing structures, etc. Despite its more than 50-year history, the helicopter is still actively operated today.
Due to the design features of the Sikorsky S-64 Skycrane, it is not suitable for carrying people on its board, while the crew of the aircraft consists mainly of 5 people, including three pilots and two engineers controlling the process of cargo transportation.
At first glance, it might seem that the Sikorsky S-64 Skycrane aircraft, due to its rather large overall dimensions, is very unstable during flight, however, given the empty interior space, it is rather the other way around, this aircraft has good maneuverability, thereby providing the ability to work even in hard to reach places.
Since the helicopter is a transport aircraft, a fairly powerful power plant is used here, consisting of three Pratt & Whitney JFTD12-4A gas turbine engines (depending on the version). Due to the particular operational capabilities of the helicopter, its flight speed is quite limited and is about 170 km \ h. At the same time, the maximum flight distance, which is about 370 kilometers, also has obvious limitations.
- Sikorsky S-64 Skycrane – the basic production version of the helicopter;
- Sikorsky S-64A Skycrane – version adapted to the needs of the US Armed Forces;
- Sikorsky S-64B Skycrane – An improved modification of a civilian helicopter.
Among other things, this aircraft, starting in 1992, was also produced by the aircraft manufacturer Erickson Air-Crane, which included two options such as:
- Erickson S-64E AirCrane – the basic version developed based on the Sikorsky CH-54A version;
- Erickson S-64F AirCrane – A modified version equipped with two engines Pratt & Whitney JFTD12-5A.
According to official figures, over a hundred production helicopters of this type were built over the entire production period.
