RÉSUMÉ
Calculation results of length and shape of 2D unsteady cavities past a wedge at periodic time dependence are presented. The variable cavity length is found in sequential instants by numerical solving the equation of mass balance of gas in the cavity. For each iteration the solution is calculated on the basis of a linear set of singular integral equations by the method of discrete singularities. The influence of elasticity of gas filling the two-dimensional ventilated supercavity is investigated. A comparative analysis of unsteady behavior of plane and axisymmetric supercavities is given.
