Download or read book Structural Dynamics of Liquid Rocket Engines written by Andrew M. Brown and published by Springer Nature. This book was released on 2023-02-14 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first Structural Dynamics book focused on this indispensable aspect of liquid rocket engine design. This book begins by reviewing basic concepts in Structural Dynamics, including the free and forced response of SDOF and MDOF systems, along with some discussion of how numerical solutions are generated. The book then moves to a discussion of specific applications of these techniques in LREs, progressing from component level (turbomachinery and combustion devices), up through engine system models, and finally to integration with a launch vehicle. Clarifies specific topics including the Campbell and SAFE Diagrams for resonance identification in turbomachinery, the complications of component analysis in the pump side due to a host of complication factors such as acoustic/structure interaction, the "side-loads" fluid/structure interaction problem in overexpanded rocket nozzles, and competing methods for generation overall engine system interface loads. Includes specific examples for illustration while closing with rotordynamic analysis, dynamic data analysis, and vibroacoustics.

Book Synopsis Dynamics of Liquid Rocket Engines by : V. A. Makhin
Download or read book Dynamics of Liquid Rocket Engines written by V. A. Makhin and published by . This book was released on 1970 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses questions of the theory and calculations of certain dynamic processes which take place with variable parameters in liquid rocket engines and their major components. Primary attention is devoted to the description of the dynamic processes and the study of methods for the engineering calculation of these processes. The differential equations of motion of the working medium and of the moving parts of the individual components are used to describe the dynamic processes of liquid rocket engines(LRE). Theoretical LRE arrangements and their static characteristics are examined. Assuming the LRE to be potentially a dynamic system, the authors derive the equations of the dynamics of the powerplant primary components. The dynamics of the LRE automation elements are analyzed and the questions of automatic regulation, trimming, and retrimming of engines using the results of firing tests are studied. The oscillatory processes in the tubing lines are examined in detail; the influence of oscillations in the pneumatic and hydraulic lines on the stability of the LRE working process is determined. An analysis is given of the LRE startup processes and the effect of the thrust tailoff impulse (TTI) on the scatter of ballistic rockets. Original material used in the analysis of several engine elements and their control systems is presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A method for calculating structural loads in a rocket engine-actuator-vehicle system is developed. The engine is attached to the vehicle by a universal-type gimbal joint and by two actuators. The engine is assumed to be a rigid body. Either the actuator loads or the engine angular acceleration is assumed to be known with a calculation of the other required. A set of algebraic equations is developed from which the unknown actuator loads or angular acceleration and the forces and moments at the gimbal point can be calculated . I.

Book Synopsis Techniques to Assess Acoustic-Structure Interaction in Liquid Rocket Engines by :
Download or read book Techniques to Assess Acoustic-Structure Interaction in Liquid Rocket Engines written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustoelasticity is the study of the dynamic interaction between elastic structures and acoustic enclosures. In this dissertation, acoustoelasticity is considered in the context of liquid rocket engine design. The techniques presented here can be used to determine which forcing frequencies are important in acoustoelastic systems. With a knowledge of these frequencies, an analyst can either find ways to attenuate the excitation at these frequencies or alter the system in such a way that the prescribed excitations do result in a resonant condition. The end result is a structural component that is less susceptible to failure. The research scope is divided into three parts. In the first part, the dynamics of cylindrical shells submerged in liquid hydrogen (LH2) and liquid oxygen (LOX) are considered. The shells are bounded by rigid outer cylinders. This configuration gives rise to two fluid-filled cavities: an inner cylindrical cavity and an outer annular cavity. Such geometries are common in rocket engine design. The natural frequencies and modes of the fluid-structure system are computed by combining the rigid wall acoustic cavity modes and the in vacuo structural modes into a system of coupled ordinary differential equations. Eigenvalue veering is observed near the intersections of the curves representing natural frequencies of the rigid wall acoustic and the in vacuo structural modes. In the case of a shell submerged in LH2, system frequencies near these intersections are as much as 30% lower than the corresponding in vacuo structural frequencies. Due to its high density, the frequency reductions in the presence of LOX are even more dramatic. The forced responses of a shell submerged in LH2 and LOX while subject to a harmonic point excitation are also presented. The responses in the presence of fluid are found to be quite distinct from those of the structure in vacuo . In the second part, coupled m.

The techniques presented here can be used to determine which forcing frequencies are important in acoustoelastic systems.

The forced responses of a shell submerged in LH2 and LOX while subject to a harmonic point excitation are also presented. The responses in the presence of fluid are found to be quite distinct from those of the structure in vacuo. In the second part, coupled mode theory is used to explore the fundamental features of acoustoelastic systems. The result is the development of relatively simple techniques that allow analysts to make informed decisions concerning the importance of acoustic-structure coupling without resorting to more time consuming and complex methods. In this part, a new nondimensional parameter is derived to quantify the fundamental strength of a particular acoustic-structure interaction irrespective of material and fluid properties or cavity size. It is be shown that, in some cases, reasonable approximations of the coupled acoustic-structure frequencies can be calculated without explicit knowledge of the uncoupled component mode shapes. Monte Carlo simulations are performed to determine the parameter values over which the approximate coupled frequency expressions are accurate. General observations concerning the forced response of acoustoelastic systems are then made by investigating the response of a simplified two mode system. The third part of this research discusses the implementation of a component mode synthesis (CMS) technique for use with geometrically complex acoustoelastic systems. The feasibility of conceptually similar techniques was first demonstrated over 30 years ago. Since that time there have been remarkable advancements in computational methods. It is therefore reasonable to question the extent to which CMS remains a computationally advantageous approach for acoustoelastic systems of practical interest. This work demonstrates that relative to the most recent release of the popular finite element software package, ANSYS, CMS techniques have a significant computational advantage when the forced response of an acoustoelastic system is of interest. However, recent improvements to the unsymmetric eigensolver available in ANSYS have rendered CMS a less efficient option when calculating system frequencies and modes. The CMS technique is then used to generate new results related to geometrically complex acoustoelastic systems.

Download or read book Design of Liquid Propellant Rocket Engines written by Dr Jim Ras and published by Lulu.com. This book was released on 2016-09-20 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book intends to build a bridge for the student and the young engineer: to link the rocket propulsion fundamentals and elements (which are well covered in the literature) with the actual rocket engine design and development work as it is carried out in industry (which is very little, if at all covered in literature). The book attempts to further the understanding of the realistic application of liquid rocket propulsion theories, and to help avoid or at least reduce time and money consuming errors and disappointments. In so doing, it also attempts to digest and consolidate numerous closely related subjects, hitherto often treated as separate, bringing them up to date at the same time.
