Strength of Thermally Stressed Units of Liquid Rocket Engines
Abstract
The majority of contemporary thermal engines have characteristic high temperature operation rates. In connection with this the creation of methods of practical rating of thermal units on their strength pertains to the most urgent problems of the applied theory of elasticity and plasticity. Many works have been published that are devoted to this problem. However, the most attention in research is given to the creation of methods of determination of stressed and strained states. The question of how should the obtained result be used for evaluating the reliability of a design has undeservedly been forgotten. This work is an attempt to fill the shown gap to some extent. It is absolutely clear that the problem of reliability of thermally stressed units cannot be set up in general form. It should be solved only in reference to a specific type of design. The author is limited to the consideration of liquid-propellant rocket engines as typical designs working under conditions of stressed thermal conditions. Problems of rating the turbopump unit, pipelines, the pressure accumulator containers, and fittings are not considered at all. Rating of these units, which are free from thermal influence, does not contain specific peculiarities and may be basically conducted with the help of well-known methods of strength analysis. For thermally stressed units, a rating on permissible stresses cannot as a rule lead to satisfactory results. Therefore, the author proposes rating on permissible displacements and deformations, which in principle is a new solution of the problem. The book includes basically the results of the author's own research conducted in 1954-1955. The book is intended for design engineers. It may also be used by students of undergraduate and graduate designing. It is assumed that the reader is sufficiently acquainted with the study of strength of materials.
