Pulsations of the parachute canopy

The problem of pulsations of the canopy of a parachute is considered. Equations which are linearized in a neighborhood of the stationary state of motion are given, the algorithm of solution that is based on the composition of the methods of discrete curls and finite differences is described. The results of computations of the characteristics of frequency of the canopy are given in the form of graphs.Translated from Dinamicheskie Sistemy, No. 9, pp. 87–94, 1990.
