|
 | A series of fumers based on magnesium/strontium peroxide was tested at the Naval Surface Weapon Center's Hypersonic Tunnel to see the effect of varying the parameters that control the rate of combustion of pyrotechnics. The parameters that were varied included spin rate, fuel content, fuel particle size, the oxidizer, and the addition of burning rate additivies (calcium resinate, polyvinylchloride, oxamide, and gelatin). The base drag reductions measured for all the ... |

|
 | A series of experiments were performed to determine environmental condition effects of HC white smoke mix. Temperature, humidity level, blending rates and time were found to have minimal effect on input sensitivities and energy release. Significant findings were; gross sublimation of hexachloroethane from stored samples; large inhomogeneities in the blended samples; and inconsistencies in impact sensitivities of all samples compared to previous results.

|
| Litharge may experience noticeable and drastic alterations in its reaction with silicon depending on the presence, extent and nature of dopant species in either or both the litharge and the silicon. Reactivity differences were measured as enthalpy of the following reaction PbO + Si yields SiO + Pb which reaction is confirmed by X-ray diffraction of product species. (Author) |

James E. Rose; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| Heat of explosion, ignition temperature, and McLain Propagation Index, PI, defined as heat of explosion divided by ignition temperature, are correlated for various pyrotechnic delay and ignition compositions. A novel propagation index, described by heat of explosion, ignition temperature, burning rate, and density is proposed as a comparative screening criterion for pyrotechnic compositions. (Author) |

|
| The effects of defect structure and doping of potassium chlorate on its chemical reactivity with respect to its propagative reactions with sulfur was investigated. The preparation of doped single crystals of potassium chlorate was continued during the entire program. The crops of single crystals were analyzed for their dopant contents. The influence of doping on the thermal decomposition of potassium chlorate was investigated by DTA and TGA. The effect of ... |

|
| A laboratory apparatus for the determination of the ignition temperatures of pyrotechnic mixtures that is based upon differential thermal analysis (DTA) has been designed, constructed, and tested. It has been evaluated by obtaining thermograms of a standard pyrotechnic mixture and each of its components. The temperatures for the crystalline transitions and melting points obtained from the DTA curves of the components of the pyrotechnic mixture were found to agree with ... |

R. M. Blunt; DENVER RESEARCH INST COLO
|
| Planck's black body data is tabulated. The data is presented from 0.35 microns to 12.0 microns in increments of 0.005 microns and at temperatures from 1500K through 4050K in 50K increments. Hemispherical power, power normalized to peak, spectral brightness, temperature exponent M, and cumulative and percentage of power between zero and the listed wavelength. In addition, graphs of the temperature exponent vs temperature and vs wavelength are included. (Author) |

|
| The sharply defined bright zone produced by the detonation of a cyanogen-oxygen mixture in small test vehicles looks promising as a pump for solid-state lasers such as neodymium-doped glass and ruby. Brightness temperatures between 6000 to 7000 K are routinely obtained. By adding inert depants such as argon, xenon and helium to the mixture, brightness temperatures in the vicinity of 8000K have been attained. The combustion or detonation that takes ... |

|
| Nonreproducibility of illuminance levels and burning rates has long been a problem with pyrotechnic compositions. One aspect of this problem is the effects of blending and consolidation on the shape and size of the particles. If the effects of consolidation pressure on particle size, permeability, or porosity vary excessively, such variations may cause nonreproducible end-item performance. An investigation revealed that increasing the loading pressures to 10,000 psi on 44, 124 ... |
