Available in PDF, EPUB and Kindle. Book excerpt: This program demonstrated that reliable, consistent combustion efficiency data could be obtained independently at different facilities. The detailed combustion efficiency performance of two Boron loaded fuel rich propellants was mapped over an air-to-fuel ratio range from 10 to 40 and a ramburner air-only pressure range from 13 to 40 psia. Two highly loaded Boron propellants were used. Testing was conducted at three facilities. Six inch subscale hardware was utilized and a coaxial mixing configuration chosen. Data analysis procedures were refined and error sources (particularly fuel flow rate uncertainties) minimized. The averaged combustion efficiency data from all three facilities fell within the computed error bands, + or - 5.5 percent. Significant A/F dependence was found for combustion efficiency for the two propellants. The effect of fuel generator pressure on combustion efficiency was briefly investigated and found to be negligible. Finally, a propellant comparison was made and ARC 256A had generally better combustion efficiency performance and a higher theoretical heating value, leading to its selection as the superior propellant.

Available in PDF, EPUB and Kindle. Book excerpt: Data on coaxial jet mixing and combustion developed during a ten-week test program are presented along with a limited analysis of results. The test was conducted with a rocket motor simulator which generated a fuel-rich primary stream. The combustion of the primary stream was varied systematically through a broad range of conditions, and the exchange processes were observed in a secondary mixing duct by means of wall pressure measurements, thrust measurements, and measurements of heat flux. Photographic observations were made of the primary stream operating as a free jet. Preliminary analysis indicates that the length of duct required for momentum and energy exchange to occur depends primarily upon the secondary air mass flow. A brief discussion is included on the grouping of variables in afterburning problems, and a simplified 'throttling number' parameter is suggested. Also included are the results of a mixing zone computation in which the differential equations of coaxial mixing are solved by a finite difference procedure. Results are presented of calculations made to predict wall pressure profiles that are influenced by the presence of the bluff face of the primary stream blast tube. This analysis covers the flow regime that extends to the length of the primary stream potential core. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes the results of an Air Force Rocket Propulsion Laboratory engineering development effort to design, fabricate and activate a laboratory-scale, direct-connect test facility. The facility, composed of a clean air supply system, a primary solid rocket combustor and a ramburner, is designed to support air-augmented rocket propellant development efforts. The versatile facility design allows variation in hardware configuration and propellant flow parameters to simulate a broad range of flight conditions, i.e., Mach No. 2 to 3.5 and altitudes from sea level to 50,000 feet. The air delivery system is designed for maximum conditions of 7 lb/sec, 1000F and 250 psia. The annular inlet manifold is adaptable to either a 2-inch-diameter, center-perforated or 6-inch-diameter, end burning primary combustor. A variable-length, 5-inch-diameter ramburner is used. The combustion processes occurring in the primary and secondary chambers are monitored by means of wall pressure and temperature measurements, thrust measurement, residue sampling and optical techniques. Facility performance capabilities, system calibration and preliminary evaluation of baseline direct-connect testing are presented. (Author).
