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.
Intermeshing rotored helicopters have high stability and powerful lifting capability. The latest Kaman K-MAX model is a dedicated sky-crane design used for construction work, and has been modified for trials by the USMC as an optionally-unmanned cargo transporter. Unmanned aerial vehicles with intermeshing rotors have also been flown. [2]
The Pratt & Whitney T73 (company designation JFTD12) is a turboshaft engine. [2] Based on the JT12A, the T73 powered the Sikorsky CH-54 Tarhe and its civil counterpart Sikorsky S-64 Skycrane flying crane heavy-lift helicopters. [3]
