The development of the reley-taylor instability in the systems with the different compressibility of the environment

The influence of the environments compressibility at the dewelopment reley-taylor instability is considered. The compressibility is found with the help of calculations according to the gaseous dynamics programme MAH and MECH leads to the increasing of the rate of the growth perturbations and width of the mixed zone. The interpretation of the calculations results explains the physical mechanism of the compressibility's influence is given.
