The Preliminary Studies of Survivability of Nozzle Throat Materials in Ultrahigh Pressure of Nitrogen and Air.

Abstract

One of the most complicated problems of the up-to-date experimental aerodynamics in simulation a hypersonic flight is the survival of a nozzle throat of a wind tunnel. An attempt to produce a flow ahead of a model, provided that the flow parameters are closely approximating natural those by general similarity criteria, leads to a rise of gas parameters in a settling chamber. In the modern operating facilities the pressure is up to 1 GPa 1, temperatures are from 2000 to 10000 K 2 for an operating time from a millisecond to several tenth fractions of a second.
