Vortex generation in solid propellant rockets
AIAA Journal, 1964Vortices are generated by acoustic oscillations as a second-order viscous effect. Traveling tangential modes in an axially perforated solid propellant rocket give a single vortex swirling about the axis. Tangential velocity at the periphery, typically a few hundred feet per second, can be predicted approximately using acoustic streaming theory modified

Virtual prototyping of solid propellant rockets
Computing in Science & Engineering, 2000Researchers seek a detailed, whole-system simulation of solid propellant rockets under normal and abnormal operating conditions. A virtual prototyping tool for solid propellant rocket motors based on first principles models of rocket components and their dynamic interactions meets this goal. Given a design specification (geometry, materials, and so on),

Combustion of composite solid rocket propellants.
AIAA Journal, 1969CONSIDERABLE work has been done on solid rocket ^->< propellants using various fuels (often polymers) and oxidizers. Recently Rastogi and Ouseph have studied the combustion of phenol-f ormaldehy de/NH 4C10 4 system . They observed that the rate of burning decreases as the amount of cross-linking increases in the polymer.

Solid Rocket Propellants: Processing Technologies
2016This chapter covers all the processing methods for the manufacture of solid propellants. Since liquid propellants do not require any elaborate processing arrangement, the manufacture of, and ingredients for, liquid propellants are excluded. Double base solid propellants for rockets are manufactured by extrusion and casting routes and both routes are ...

The Future for Solid Propellant Rockets
The Journal of the Royal Aeronautical Society, 1959Ten years ago it seemed that the solid propellant rocket engine could make only a limited contribution to rocketry. Although it was simpler and more compact than its liquid propellant rival it suffered from three serious drawbacks. The nozzle was uncooled and so the burning time had to be short, the entire propellant container was subjected to the full

Fracture of solid rocket propellant grains
Engineering Fracture Mechanics, 1992Abstract The importance of fracture criteria in the failure assessment of solid propellant grains is briefly described. Computation of the crack tip stress intensity factor and the development of the crack growth rate equation through fracture properties essential for fracture analysis are also discussed.
