“…When the line is pulled first, it can cause the line sail phenomenon, also called the line bowing or fish hooking phenomenon, as shown in Figure 1. It can have an adverse effects on the inflation process of the main parachute, and Moog et al [38], Purvis et al [39,40], Johnson et al [41], Peterson et al [42], and Maydew et al [43] have made detailed studies of it. They discussed six situations: prolonged opening time, collision between the parachute bag and the canopy, high cord straightening force, asymmetric opening, wear of the canopy by the parachute bag, and unpredictable parachute inflation.…”

The application of the Kane equation in analyzing airdrop dynamics problems is rare. The main objective of this paper is to apply the Kane equation dynamics model to the analysis of the status continuity problem during the out-of-cabin process and the line sail phenomenon during the extra-vehicular process. In the out-of-cabin process, an analysis of off-aircraft security and traction ratio impact was conducted. Furthermore, the BP neural network model was trained to predict the status transition of the payload for a multiple airdrop mission. In the extra-vehicular process, the spring network method was used together with the Kane equation to analyze the form and overload of the parachute line. The modeling avoids complex equations and derivations. The results suggest significant potential applications of the Kane equation in precision airdrop missions during out-of-cabin and extra-vehicular processes without heavy reliance on experimental data.

A 30-ft-diameter ringslotholid parachute was designed, developed, and tested at Sandia National Laboratories as the major component of a flight termination system required for a 1900-lb gliding delivery platform. Four full-scale sled tests were performed to validate the design models of the parachute, determine reefing line length, demonstrate structural adequacy of the parachute materials, and demonstrate that performance met the design requirements.
