Studies pertaining to solid propellant fracture
Gerald Herbert Lindsey
The study of propellant fracture has been subdivided into three parts: a fracture criterion is developed for stress fields producing mixed mode crack propagation by drawing a comparison with fracture in uncracked geometries; a means for predicting crack growth and velocity has been developed for linear viscoelastic materials strictly on the basis of stress intensity factors. A fracture characterization of critical stress intensity factor for a CTPB propellant has been completed, which facilitates the application of the theory; and, extensive dewetting experiments have been completed which have confirmed prior theoretical developments of a quasielastic dewetting theory.

Ammonium perchlorate composite propellant (APCP) is a modern solid-propellant rocket used in rocket vehicles. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance, but also by the nature of how it . Solid rocket propellants are the oldest and simplest of all forms of rocket propulsion, dating back to antiquity. The solid-propellant engine is formed as a tube filled with a solid-form mixture of chemicals, which burn at a rapid rate and produce gases, that are ejected from a rocket nozzle. Solid propellants have a high density and can burn.
SOLID PROPELLANTS In this chapter we describe several common solid rocket propellants, their principal categories, ingredients, hazards, manufacturing processes, and qual- ity control. We also discuss liners and insulators, propellants for igniters, tailoring of propellants, and propellants File Size: KB.

Geometrical modeling of the propellant grain The burn back methodology used in this study is solid modeling of the propellant grain. In general, the solid propellant grain at the beginning of the operation is modeled parametrically. The parameters that change during the File Size: KB. ballistic missiles.

Solid propellants were, eventually, easier to make, safer to store, lighter in weight (because they did not require on-board pumps), and more reliable than their liquid predecessors.

Teague. In this study, evaluation of fracture toughness on a solid propellant was carried out under the assumption that the solid propellant is a linear viscoelastic material.
The present work is aimed at studying the fracture behavior of a hydroxyl-terminated polybutadiene solid rocket propellant. A fracture mechanics method based on the J integral was adopted to evaluate the material’s resistance against crack initiation and propagation with the auxiliary of a high-speed microscopic camera and multiple-sample test by: 4.
Dynamic loads generated in a shock tube were applied to the inner bore of annular specimens of a simulated solid propellant. The load pulse-shape was approximately triangular, with essentially zero rise-time, a duration of about msec, and a variable intensity.
At each particular pressure level the loading was repeated on a specimen until fracture of the specimen : Glenn Secor. tensile fracture, of an energetic propellant called Propellant B. Previous work [I] had shown that a microfracture model containing nucleation, growth, and coalescence processes for cracks is effective in describing dynamic fracture, spall, and fragmentation in a propellant.
Three simple conclusions can be drawn from the parameter studies. (1) An enhancement of any fracture-inhibiting mech- anism (e.g. roughness, heat loss, seepage loss, confining stress) causes a decrease in fracture lengths and it slows the pressure by: Fundamental Studies Relating to Systems Analysis of Solid Propellants R.

A cracked solid propellant would have failure or fracture of rocket because of excessive combustion according to increase of burning area, therefore it is important to evaluate the fracture.

The propellant was considered to be an isotropic, solid material; although in reality it was a composite of solid oxidizer particles imbedded in and bonded to a carbon fuel matrix. After an initial linear region, nonlinear stress-strain behavior under loading resulted from the progressive failure of these bonds at the interfaces between the.
