A Study of Liquid Boric Oxide Particle Growth Rates in a Gas Stream from a Simulated Jet Engine Combustor


Book Description

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.







Preliminary Evaluation of Hi-Cal-3, Hef-2, and a Solution of Pentaborane - JP-4 Fuel in a 1/4-sector of Annular Turbojet Combustor


Book Description

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.

Book Description

This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.
