Abstract : The attainment of high projection velocities of ballistic projectiles is connected with the generation of flow zones of high-temperature (2000-6000K) and high-pressure (5000-10,000 atm) gases. Under such circumstances the gas differs markedly from the ideal case because of dissociation, ionization, and mixture component interaction. The present paper investigates the influence of equilibrium dissociation on the real gas flow through tubes, using air as the example. The related thermodynamic functions depend on temperature and pressure, and the paper utilizes pertinent data as found in tables compiled after approximating them by polynomials. The dissociation influence calculations are carried out using the method of characteristics of the real gas flow through cylindrical tubes. (Author)
