After presenting the experimental and theoretical researches on whipcrack phenomenon, the current study gives a particular description of Krehl's experimental results, the whip models based on conservation of energy and based on conservation of momentum, and the current researches on this unique phenomenon. Finally, the characteristics of whipcrack were acquired, and the comparison between the whipcrack and other large flexible structures ‘swing phenomena such as the huge parachutes’ whip or the “probe-drogue” in-flight refueling system's whip showed that there was much comparability, so the study of the whipcrack phenomenon will help researchers obtain a better understanding of these phenomena.
