Computing experiment in the task about the flutter rectangular plate

The flutter of the rectangular plate at any direction of the velocity vector concerning the parties of the plate is considered. The numerical algorithm without saturation for the solution of the corresponding task on eigenvalues is constructed. Results of calculations of critical flutter speed and the approximate formula for the critical speed which at the set direction of the velocity vector of the flow, depends on two dimensionless parameters are given: dimensionless sonic speed in the plate and the dimensionless thickness of the plate.
