A method for the simulation of conditions of a maximum speed of flight for material tests

摘要

A method for the simulation of conditions of a maximum speed of flight in the case of a high static ambient pressure pumreal of at least 10 kpa for carrying out of material tests, wherein a gas with a defined pressure psim and a defined temperature tsim is provided in a reservoir, whereby the gas is forced through a nozzle of the reservoir into an environment is discharged, wherein the with a mach number sim gas flowing out from the nozzle on one side of a material sample, whereby the outflowing gas on the surface facing a pressure of the material sample preal and a temperature treal formed, which the conditions at a surface of a missile flight at the maximum speed to a mach number mreal, and wherein the same tsim treal, characterized in that sim is smaller than mreal psim in order, and in that at least 40% is smaller than a in order to achieve the mach number at mreal pumreal pressure necessary, but by at least 30 is greater than a in order to achieve the mach number at sim pumreal..
