INVESTIGATION OF THE THERMODYNAMIC PROPERTIES OF PROPELLANT INGREDIENTS AND THE BURNING MECHANISMS OF PROPELLANTS
Abstract
Work on the heat of formation of alane-terminated liquid beryllium hydride (code ATBH) was completed. From heat of hydrolysis in an HCL-dioxane- water mixture, the heat of formation was derived as -268.6 kcal/mole or -33.65 kcal/100 grams. Heat of solution measurements and X-ray diffraction results indicate diammonium hydrazinium tetraperchlorate (code DAHTP) is a physical mixture of ammonium perchlorate and hydrazinium diperchlorate and not a new compound. The heat of combustion of purified 1,2,3-tris(1,2-bis (difluoroaminoethoxy)) propane (code TVOPA) in oxygen was measured by rotating bomb calorimetry. The derived heat of formation of TVOPA is -208.1 kcal/mole (heat of formation of aqueous HF from NBS Tech. Note 270-1). Work in progress includes the heat of formation CF3ONF2 by explosion of a mixture with hydrogen and the heat of explosion of mixtures of cyanogen and NF3 with the aim of defining the heat of formation of CF4. The flash pyrolytic combustions of boron in oxygen, oxygen and water, and in chlorine are described in terms of the time history of selected species as measured by kinetic spectroscopy.
