  • About the Edition

    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.   AO Principles of Fracture Management: Vol. 1: Principles, Vol. 2: Specific fractures, Edition 3 - Ebook written by Richard E.

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.
