Experimental study of thermophysical properties of liquid pure hydrazine at various temperatures and pressures

Abstract

The paper studies the areas of application of liquid pure hydrazine and its derivatives. In order to obtain the complete information about its thermophysical properties, we carried out the experimental studies in a wide range of pressure and temperature parameters under conditions of natural convection. To conduct such studies, experimental facilities and work sites were constructed on which various modern methods were implemented. As a result, it was possible to determine the thermophysical properties of liquid pure hydrazine with high accuracy. Findings are presented in tables. Moreover, we developed methods to improve the efficiency of using liquid pure hydrazine, which will increase the efficiency of liquid rocket engines and single-and-multi-use power plants for air-launched, aerospace-based and space-based aircraft.
