Sky crane is a soft landing system used in the last part of the entry, descent and landing (EDL) sequence developed by NASA Jet Propulsion Laboratory for its two largest Mars rovers, Curiosity and Perseverance. While previous rovers used airbags for landing, both Curiosity and Perseverance were too heavy to be landed this way. Instead, a ...
Sky crane or skycrane may refer to: A type of aerial crane helicopter pioneered by Sikorsky in 1950s and 1960s where the fuselage is only large enough to accommodate the pilot and crew and does not have a cargo hold or passenger area.
Originally a Sikorsky Aircraft product, the type certificate and manufacturing rights were purchased from them by Erickson Air-Crane in 1992. Since that time, Erickson Air-Crane has become the manufacturer and world's largest operator of S-64 Aircranes and has made over 1,350 changes to the airframe, instrumentation, and payload capabilities of the helicopter.
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 heavy lift ...
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.
The descent stage ("sky crane"), parachute and heat shield all came to rest within 1.5 km of the rover (see satellite image). Having come within five meters (16 ft) of its target, [ which? ] the landing was more accurate than any previous Mars landing; a feat enabled by the experience gained from Curiosity ' s landing and the use of new ...
The Sikorsky S-64 Skycrane has been in service for over five decades. 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 ...
The Hughes XH-17 "Flying Crane" was the first helicopter project for the helicopter division of Hughes Aircraft Company.The XH-17, which had a two-bladed main rotor system with a diameter of 134 feet (41 m), still holds the world record for flying with the largest rotor system.
