Grain velocities during ignition of gun propellant
Combustion and Flame, 1975Abstract By means of a dual-flash X-ray technique, propellant grain velocities during ignition have been determined for the Navy 5-in./38 gun. At the completion of ignition, the velocity profile along the grain bed is sharply peaked with maximun velocity at the propellant free surface.

Combustion Diagnostics of Propellant with New Grain Geometries
1988Abstract : High progressivity/density (HPD) propellants are under consideration at the Ballistic Research Laboratory (BRL) for a variety of enhanced ballistic applications. The HPD concept involves the tailoring of the mass generation rate to match the increasing chamber volume as the projectile moves down the gun tube.

Bulk Properties of Grain as Affected by Self-Propelled Rotational Type Grain Spreaders
Transactions of the ASAE, 1983ABSTRACT A self-propelled rotational 4-trough grain spreader constructed at the U.S. Grain Marketing Research Laboratory and two commercially available rotational type grain spreaders were used to fill a 6.4-m diameter bin with wheat, corn, and grain sorghum. The grain for filling was choke-fed through an orifice to the spreaders.

On the dynamics of propeller-like dust grain in plasma
Physics of Plasmas, 2013The equations of motion of a dust grain with non-spherical shape in plasma are generalized by incorporating the effects associated with propeller-like features of the grain's shape. For the grain shape close to rotationally symmetric, the stability of “stationary” (in terms of variables used in the grain dynamic equations) solutions are considered.

The Strain Analysis of Solid Propellant Rocket Grains
Journal of the Aerospace Sciences, 1960There is often a wide divergence of interest between the missile engineer responsible for thrust performance on the one hand, and the motor tube manufacturer concerned with chemical composition on the other. The propellant grain design analj^st interested in structural integrity is, therefore, frequently hard put to compromise both aims efficiently in ...
