Advanced Control of Aircraft, Spacecraft and Rockets introduces the reader to the concepts of modern control theory applied to the design and analysis of general flight control systems in a concise and mathematically rigorous style. It presents a comprehensive treatment of both atmospheric and space flight control systems including aircraft, rockets (missiles and launch vehicles), entry vehicles and spacecraft (both orbital and attitude control). The broad coverage of topics emphasizes the synergies among the various flight control systems and attempts to show their evolution from the same set of physical principles as well as their design and analysis by similar mathematical tools. In addition, this book presents state-of-art control system design methods - including multivariable, optimal, robust, digital and nonlinear strategies - as applied to modern flight control systems. Advanced Control of Aircraft, Spacecraft and Rockets features worked examples and problems at the end of each chapter as well as a number of MATLAB / Simulink examples housed on an accompanying website at http://home.iitk.ac.in/~ashtew that are realistic and representative of the state-of-the-art in flight control.

The turboprop engine, which was developed at the close of World War II as a powerplant for high performance fighters, was soon to become the standard engine for many commercial long-range airliners. This book covers the early experimental types in the 1940s, the classic airliners of the 50s like the Britannia and Viscount and the modern executive machines. It also features aircraft which have prolonged their flying life with the installation of turboprop engines. Today, one of the major attractions of the turboprop is that it has a low running cost which, with increased fuel prices, makes it popular with short-range freight and passenger operators. The Aero Spacelines Guppy is the ultimate expression of the turboprop freighter since, with its cavernous hold, it can carry whol e sections of aircraft fuselages. Turboprop Airliners is part of a series of titles which combine to give a complete history of aviation.

This book contains some of the most workmanlike aircraft ever built. These include crop-sprayers, ambulances, utility aircraft, such as the Polikarpov Po-2, and light transports which can carry anything from people to livestock. General Aviation aircraft have remarkably long service lives; they may be fitted with improved engines, avionics and have stretched airframes, but the basic design remains the same. Some, like Rockwell and Beechcraft designs, have been in service since the 1940s and 50s and have been through four or five variants.

The great leaps in aviation history - the Wright brothers'first flight, Lindbergh's first crossing of the Atlantic, Yeager breaking the sound barrier - were all made by pushing the boundaries of aeronautical science, wringing extraordinary performance out of experimental and untested aircraft. However, for every success like these there were new aircraft designs which flew badly (or not at all), crashed on landing, burned up fuel at an alarming rate, exploded without warning, or pointlessly wasted millions of dollars. The World's Worst Aircraft takes a lighthearted look at 150 of these flying failures - old and new - and asks the pertinent questions. Why did they ever get off the drawing board? What went wrong? Why were they sq unreliable, and how much money was wasted by governments, manufacturers and individuals trying to make them a success? Each aircraft is illustrated with a full-page photograph, annotated to show particularly bad, dangerous or unusual features. The lively text provides an insight into the history and (lack of) development of each type, alongside archive images from the aircraft's heyday, artworks or diagrams. Featuring some of the world's weirdest, strangest and most dangerous planes, this book is a perfect illustration of how not to build aircraft.

Published to help the beginning designer through some of the preliminary phases of aircraft design. The nomogram and design procedure described in this book are aids I developed as a result of a design study for "Crawdad" — an ultralight foot-launched motor glider that I hope to build. In the process of learning about aircraft design I discovered the various useful performance and design nomograms of Raoul Hoffman, a noted practical aerodynamicist of the 30's and 40's. His alignment charts were useful because I could obtain answers to involved problems in aerodynamics by drawing straight lines connecting the related aircraft performance parameters. With this background, I was inspired to seek a single nomograrn that I could use to make parametric studies for future designs. With the aerodynamic relations contained on a single graph, the calculation could then proceed in a systematic manner, since the answers from one graphical construction would be automatically available as data for the next. An attractive feature of the nomogram is that it is "preprogrammed" so that we don't have to worry about exponents and conversion factors in the equations. All of the governing aerodynamic relations are built into the design of the scales and we can dispense with the tedious algebra Finally, by using a plastic template and a graphical construction technique, we can simplify the task of finding the rate of climb versus airspeed. One part of the template is used to find the gliding sink rate and the other part gives the rate of climb produced by the engine brake horsepower lifting the weight of the airplane with an efficiency corresponding to that of an idealized propeller. Using each part of the template as a French curve having the mathematically correct shape, we can immediately draw the two curves and subtract to find the rate of climb. The intersection of the curves gives the maximum level speed. The template is positioned using the reference points obtained from the graphical calculation with the nomogram. Then, we can use the reference scales on the template to make rapid parametric studies for the effects of altitude, weight, drag, brake horsepower, propeller diameter, and airplane size. The book began as an instruction pamphlet for the use of the nomogram, but it has evolved into the present handbook, with the detailed sample calculation, parametric study and theoretical background. The governing equations are tabulated for the convenience of those who want to program them on a computer and a sample listing for a FORTRAN computer program for the performance analysis is given in Appendix E. However, the answers obtained from the nomogram and the graphical construction of the rate of climb curve are adequate in the preliminary design stages. Although the computer will give greater numerical accuracy, the approximations of the governing equations do not justify keeping accuracy greater than two or three digits. The book is written for the homebuilder as well as for the beginning aerodynamicist. The first part of the book is devoted to practical considerations and is meant to be self-contained. The Airplane Performance and Design Nomogram can be used without really having to understand the details of the aerodynamic analysis of Part 2, which can be deferred until a working knowledge of the design process is established. In this way, the homebuilder or novice engineering student can gain confidence and experience by working with practical examples before trying to study the mathematics of aerodynamics. The book and nomogram will be especially useful as a supplementary text to aid the student with his (or her) preliminary aircraft design project.
