Flight Vehicle Aerodynamics

Flight Vehicle Aerodynamics PDF Author: Mark Drela
Publisher: MIT Press
ISBN: 0262526441
Category : Science
Languages : en
Pages : 304

Book Description
An overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. This book offers a general overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. A particular focus is the technique of velocity field representation and modeling via source and vorticity fields and via their sheet, filament, or point-singularity idealizations. These models provide an intuitive feel for aerodynamic flow-field behavior and are the basis of aerodynamic force analysis, drag decomposition, flow interference estimation, and other important applications. The models are applied to both low speed and high speed flows. Viscous flows are also covered, with a focus on understanding boundary layer behavior and its influence on aerodynamic flows. The book covers some topics in depth while offering introductions and summaries of others. Computational methods are indispensable for the practicing aerodynamicist, and the book covers several computational methods in detail, with a focus on vortex lattice and panel methods. The goal is to improve understanding of the physical models that underlie such methods. The book also covers the aerodynamic models that describe the forces and moments on maneuvering aircraft, and provides a good introduction to the concepts and methods used in flight dynamics. It also offers an introduction to unsteady flows and to the subject of wind tunnel measurements. The book is based on the MIT graduate-level course “Flight Vehicle Aerodynamics” and has been developed for use not only in conventional classrooms but also in a massive open online course (or MOOC) offered on the pioneering MOOC platform edX. It will also serve as a valuable reference for professionals in the field. The text assumes that the reader is well versed in basic physics and vector calculus, has had some exposure to basic fluid dynamics and aerodynamics, and is somewhat familiar with aerodynamics and aeronautics terminology.

Aerodynamic Principles of Flight Vehicles

Aerodynamic Principles of Flight Vehicles PDF Author: A. G. Panaras
Publisher: AIAA (American Institute of Aeronautics & Astronautics)
ISBN: 9781600869167
Category : Aerodynamics
Languages : en
Pages : 0

Book Description
In "Aerodynamic Principles of Flight Vehicles" Argyris Panaras examines the fundamentals of vortices and shock waves, aerodynamic estimation of lift and drag, airfoil theory, boundary layer control, and high-speed, high-temperature flow. Individual chapters address vortices in aerodynamics, transonic and supersonic flows, transonic/supersonic aircraft configurations, and high-supersonic/hypersonic flows, beginning with definitions and historical data, and then describing present-day status and current research challenges. Emphasis is given to flow control, to the evolution of flight vehicle shapes as flight speed has increased, and to discoveries that enabled breakthrough developments in flight. The book: examines why various equations and technologies were developed, explains major contributors in areas such as vortices and aircraft wakes, drag buildup, sonic boom, and shock wave-boundary layer interactions, among others, and helps readers apply concepts from the material to their own projects. Archival and encyclopedic, "Aerodynamic Principles of Flight Vehicles" is a superb reference for aeronautical students and professionals alike. Although most beneficial to readers with a working knowledge of aerodynamics, it is accessible to anyone with an introductory understanding of the field.

Book Description
"Written by one of the leading aerospace educators of our time, each sentence is packed with information. An outstanding book." — Private Pilot "Illuminated throughout by new twists in explaining familiar concepts, helpful examples and intriguing ‘by-the-ways.’ A fine book." — Canadian Aeronautics and Space Journal This classic by a Stanford University educator and a pioneer of aerospace engineering introduces the complex process of designing atmospheric flight vehicles. An exploration of virtually every important subject in the fields of subsonic, transonic, supersonic, and hypersonic aerodynamics and dynamics, the text demonstrates how these topics interface and how they complement one another in atmospheric flight vehicle design. The mathematically rigorous treatment is geared toward graduate-level students, and it also serves as an excellent reference. Problems at the end of each chapter encourage further investigation of the text’s material, the study of fresh ideas, and the exploration of new areas.

Flight Vehicle Performance and Aerodynamic Control

Flight Vehicle Performance and Aerodynamic Control PDF Author: Frederick O. Smetana
Publisher: AIAA
ISBN: 9781600860577
Category : Aerodynamics
Languages : en
Pages : 392

Book Description
Annotation "Flight Vehicle Performance and Aerodynamic Control is designed to serve as a text for either an 11-week or a 16-week course at the sophomore level. It explains typical methods used to estimate aircraft performance, the theoretical basis of these methods, and how various parameters derived from the aircraft geometry can be used to estimate the requirements of control surfaces and the aerodynamic forces required to actuate these surfaces. This book includes time-tested computer programs that perform the analyses in a manner that reduces student error and improves result accuracy. Because the source code is given, users with a FORTRAN compiler can modify the program to suit particular needs. The major advantage of the software is that more realistic problems may be treated and the effects of parametric programs are more accurate than calculators. The programs are available as executables for Windows machines as well as in ASCII source code versions that can be readily compiled and then executed on Unix, Linux, and Macintosh machines and on mainframes.
