STUDY OF ROCKET ENGINE EXHAUST PRODUCTS

Abstract

A research program was undertaken to determine the physical and thermodynamic properties of BeF2 (s,l,g), BeO(s,g), and BeF(g) formed by the combustion of propellants. A special facility for the handling of Be compounds has been constructed and is being employed for the determinations. By employing the Knudsen effusion technique and operating in the temperature range 550-780 C the heat of evaporation (53.25 kcal), entropy of evaporation (38.7 e.u.), and entropy at 1000 k (27.7 e.u.) were determined for BeF2. The melting point of BeF2 has been definitely established to be 543 + or -3 C. (Author)
