PDF-(BOOK)-Dynamics and Simulation of Flexible Rockets

Dynamics and Simulation of Flexible Rockets provides a full state multiaxis treatment of launch vehicle flight mechanics and provides the state equations in a format that can be readily coded into a simulation environment Various forms of the mass matrix for the vehicle dynamics are presented The book also discusses important forms of coupling such as between the nozzle motions and the flexible bodyThis book is designed to help practicing aerospace engineers create simulations that can accurately verify that a space launch vehicle will successfully perform its mission Much of the open literature on rocket dynamics is based on analysis techniques developed during the Apollo program of the 1960s Since that time largescale computational analysis techniques and improved methods for generating Finite Element Models FEMs have been developed The art of the problem is to combine the FEM with dynamic models of separate elements such as sloshing fuel and moveable engine nozzles The pitfalls that may occur when making this marriage are examined in detail.

This book unifies all aspects of flight dynamics for the efficient development of aerospace vehicle simulations. Now in its second edition, its purpose is still to provide the reader with a complete set of tools to build, program, and execute simulations. Unlike other books, it uses tensors for modeling flight dynamics in a form invariant under coordinate transformations. For implementation, the tensors are converted into matrices, resulting in compact computer code. The reader can pick FORTRAN templates of missiles, aircraft, or hypersonic vehicles from the complimentary CADAC CD-ROM to jump-start a particular application, and plot the results of CADAC Studio. It is the only textbook that combines the theory of modeling with hands-on examples of three-, five-, and six-DoF simulations. This new and enlarged edition also serves as anchor for a self-tutoring, three-part course of aerospace simulations in C++, available from AIAA. advanced undergraduate and graduate instruction or for self-study. Seventy eight problems and nine projects amplify the topics and develop the material further. Qualified instructors can obtain a complimentary solution manual from AIAA. which reviewed state-of-the-art FORTRAN simulations, has been replaced by the description of three self-study CD-ROMs of aerospace simulations in C++. These CDs broaden the applications of this book by spanning from simple three degrees of freedom cruise missiles to high fidelity missiles, aircraft, and hypersonic vehicles. The new Appendix D lays the theoretical foundation of tensor flight dynamics. It contains the proofs of the rotational time derivative and the Euler transformation.
