J. M. Grezeszak; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| Rocket motors which generate high thrust over a very short period of time are becoming ever increasingly in demand in today's rocket motor inventory. Application which traditionally have been reserved for gun technology are now being considered for high-performance, short-action-time rocket motors. This study examines one particular rocket motor grain design, a double-base formulation in a 'screen' propellant form. Six rocket motor static firings were performed to examine performance characteristics. ... |

| An Improved Smoothing Method for Closed Burning Rate Data Reduction, |
OCT 1984 |
|
| Authors:
W. Lippincott; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| This paper describes a variable smoothing method which was developed to compute closed bomb burning rates. For the variable smoothing method, the smoothing interval is gradually decreased as the pressure increases. The data can be smoothed to within one point of the silvering pressure without any inaccuracies resulting from using data in that region. The variable smoothing method was used for computing burning rates for Navy LOVA and NACO propellant ... |

OCT 1984 |
|
| Authors:
W. Lippincott; F. Silverman; S. E. Mitchell; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| It was observed that the burning rate properties of the CAB/NC/RDX LOVA propellant appeared to vary depending on the granulation of the actual sample being tested. In order to understand this behavior, a series of samples with varying web sizes and perforation diameters was made of the CAB/NC/RDX propellant in both the bimodal and the unimodal versions. These were used for closed bomb burning rate tests. The results showed a ... |

|
| This paper discusses the component development of a new rocket motor, the 5.0-Inch Rocket Motor Mk 22 Mod 4. The Mk 22 Mod 4 is unique from its predecessors in that it is a tractor motor. This approach was taken to eliminate costly assemblies used by previous versions and to minimize field preparation prior to use. The component development effort included metal parts design and fabrication, grain obturation design, prediction ... |

| Authors:
K. P. Hennessey; P. P. Ostrowski; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| The MK 66 MOD 1, 70-mm (2.75-inch) solid propellant rocket, a widely used ordnance item, is susceptible to afterburning in the exhaust plume. The propellant, NOSIH-AA2, an extruded double-base, burns fuel-rich, producing a high percentage of CO and H2 at a flame temperature of 2335 C (4235 F) and burns for 1.07 seconds. Afterburning is undesireable, as the flash can alert the enemy, disclose the launch location, and saturate night ... |

|
| Explosive sensitivities, major field tests, and some accidents in transportation were compiled for selected monopropellants, slurry explosives, and blasting agents. To supplement information in the literature, the projectile impact, card gap, and General Electric input-output sensitivities of certain slurry explosives and blasting agents were measured. It was concluded that the projectile impact, the card gap, and the cap test results all depend on the method of conducting of the test ... |

R. C. Wilson; T. Liggett; G. C. Cox; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| A study was made to determine a feasible method for removing pelletized nitrocellulose (PNC) fines from the PNC manufacturing process separation system filtrate purge. Fines removal is necessary to eliminate a source of environmental pollution and to reduce product losses. Laboratory experiments demonstrated that conventional pressure filtration, and also sand filtration, would be unsatisfactory. Pilot plant scale tests performed with a special high turbulence continuous filter were successful. Tests with ... |

A. J. Colli; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| The feasibility was demonstrated of making spherical aluminum powders for use in propellant grains by rounding commonly available random-shape aluminum powder in a fluid energy mill operating on inert gas. The powders produced meet the specifications for the Standard Missile Rocket Motor Mk 56 Mod 0 and the Sidewinder 1C propellants and can be tailored to meet other needs. The total cost is about $5 per pound less than that ... |

| Authors:
A. J. Colli; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| Ammonium perchlorate was continuously ground in a 'jet mill' with helium gas and with nitrogen gas for comparison. The highest grinding efficiency and submicron-sized fractions were developed when heated helium was used. Continuous mixing of the ground oxidizer, with the other propellant ingredients dispersed in an inert gas, is proposed in a specially designed mixing tube. (Author) |

| Authors:
Alfonso Campolattaro; Ottmar H. Dengel; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| The analysis of the static solutions shows that the determination of the concentration of negative ions in a flame can be used as a method for checking if a flame has reached the static configuration. This follows from the fact that the concentration of negative ions must be zero for a flame in static state, which means that the only process occurring in a static-state flame is that process which ... |

Alfonso Campolattaro; Ottmar H. Dengel; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| The general results of the approach which regards a flame as a partially ionized gas which is stable in a space region where this plasma is confined are described. The boundary of this region defines the flame profile. A system of linear differential equations has been deduced, and its solutions which satisfy the prescribed stability conditions have been determined and analyzed. The approach, characterized by a marked handiness of the ... |

J. E. Geist; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| The report reviews a project for the extrusion of fluorocarbon propellants by the application of ultrasonic energy to the extrusion die. The project showed that the ultrasonic method increased the extrusion rate and improved the product homogeneity. In addition, it is expected that surface finish will be improved and the extrusion of nonsymmetrical sections will be feasible on a full-scale application. (Author) |

| SPINNING DETONATION IN NITROGLYCERIN, |
29 MAY 1968 |
|
| Authors:
Martin F. Zimmer; NAVAL ORDNANCE STATION INDIAN HEAD MD
|
| A model for initiation and propagation of low-velocity detonation in nitroglycerin is proposed and discussed. It assumes interaction of incident and reflected shock waves and, under certain conditions, formation of Mach waves--locations of high pressures assumed to be centers of initiation. Experimental evidence to support the model is given and results are compared with two other models put forward recently, based on the assumption of precursor wall waves. (Author) |
