the active Soyuz APDA (Table 4.1), which were later reproduced in comprehensive dynamic testing. An analogous model was used by NASA specialists to analyze docking with an active Apollo APDA [47]. Introduced into the model were the characteristics of the shock absorption system, rated theoretically and refined using the results of testing. Table 4.1. Initial conditions of docking in dynamic qualification tests. a. case; b. m/s; c. m; d. degrees/second; e. degrees; f. temperature, degrees. The calculations were done on a BESM-6 computer, and the results of modeling were recorded on punched cards and in the form of a table; they were then turned into graphs using an automatic plotter. An image of the docked ships (Figure 4.6) was reproduced on the screen of a display [10]. An examination of the graphs which were photographed for convenient use on film, confirmed the correctness of the modeling results and additional analysis of the kinematics of relative motion. Information on the punched cards was used during qualification testing of the APDAs to fix on the same graphs the results of calculations and testing (Figures 4.7 and 4.8). Comparison showed a satisfactory coincidence of both results. The difference was manifested mainly in the value and character of
