Describes the construction of the software module approximate investigation of the dynamics of deployment parachute canopy. Discovery process is modeled by the motion of perfectly flexible elastic thread - frame strip, passing in a sling. The equations of motion that Coy-string are replaced by discrete counterparts. At the initial stage of expansion, when the canopy has not yet fulfilled part, applies to "force boost" - the dome probetsya constant pressure differential acting up until the pole is formed executed region. After this drop in the backlog of the dome is assumed to be zero, and the completed parts - a constant in the dome with the addition of the calculated dynamic component. The proposed software module allows the calculation of the basic relations describing the process of opening the dome, determine the values of congestion in the thimble, the pole and on the edges of the dome. The possibility of modification of the module for solving the dynamics of opening the parachute with a dome or cupola rifovannym arbitrary shape.


deployment of the canopy, flexible string, ribbon frame, differential pressure, generalized schroud line; psevdoviscosity mechanism, a software module.
