Calculation of the Energetic Characteristics of TN in Composite Solid Propellants

摘要

This paper introduces the physiochemical properties of a new organic oxidizer - 2, 3, 5,6 -tetranitrato - 1,4 - Dinitropiperazine (TN). Based on White's minimization of Gibbs free energy principle, its energetic characteristics in solid propellants are investigated with the aid of a computer. The results indicate that the theoretical specific thrust of a composite solid propellant consisting of TN, aluminum powder (Al) and HTPB can reach 276 sec, approximately 10 sec. higher than the Ap, Al and HTPB series of propellants. This demonstrates that TN is indeed a high energy oxidizer. In addition, characteristics of smokeless propellants consisting of TN and HTPB are being studied preliminarily in this paper.
