It was experimentally determined that the liquid boric oxide particles leaving a jet engine combustor, burning a boron-containing fuel, will have diameters of 1.0 x 10(exp -5) to 2.0 x 10(exp -5) centimeter. For this size range the particle heat-transfer and drag coefficients are essentially infinite. The results may be applied to any boron-containing fuel. Equations are developed that enable the calculation of the particle size-time history. A study of boric oxide deposition mechanisms is included, and suggestions for decreading deposition rates given.

A brief combustion study of three boron-containing fuels was made in a 1/4 sector of an annular turbojet combustor. The three fuels were Hi-Cal-3, HEF-2 (primarily propylpentaborane), and a solution of 63 percent by weight pentaborane in JP-4 fuel. The combustion efficiencies of the three fuels were between 90 and 95 percent. A photographic comparison of deposits in the combustor is presented.
