Приведено большое количество фотографий, подробные чертежи, схемы камуфляжа. Текст на японском языке (английским дублируются подписи к ряду изображений). The first series of Famous Airplanes of the World was published between 1969 and 1986. It comprises a series of highly illustrated monographs on various aircraft types. Each edition provides a 8-page narrative development history of the type (and sub-types) and technical data tables. Also included is a 8-page chapter on the types' operational service / use and a description of the camouflage and markings worn (with tone profile drawings). The text is entirely in Japanese, except for English chapter headings.

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.

This is a book of entertaining problems that can be solved through the use of algebra, problems with intriguing plots to excite the readers curiosity, amusing excursions into the history of mathematics, unexpected uses that algebra is put to in everyday affairs, and more. Algebra Can Be Fun has brought hundreds of thousands of youngsters into the fold of mathematics and its wonders. It is written in the form of lively sketches that discuss the multifarious (and exciting!) applications of algebra to the world about us. Here we encounter equations, logarithms, roots, progressions, the ancient and famous Diophantine analysis and much more. The examples are pictorial, vivid, often witty and bring out the essence of the matter at hand. There are numerous excursions into history and the history of algebra too. No one who has read this book will ever regard mathematics again in a dull light" Reviewers regard it as one of the finest examples of popular science writing.

A conceptual guide to the martial arts, the book features Jeet Kune Do, Bruce Lee's brilliant martial art, which uses elements from many physical art forms: Western boxing, muay Thai Boxing, kali, shoot wrestling and Brazilian ju-jitsu. In addition to the philosophical and practical bases for the martial arts, Balicki covers: * Equipment training: Thai pads, focus gloves, the dummy, kickshields * Weapons and weapons training * Fighting multiple opponents * Psychological training * Trapping: training, confrontation, grappling and groundfighting * Training for the disabled * Legal issues For the fighter, the teacher or the fascinated observer, these principles are greater than the sum of themselves, offering insight into a legendary discipline.

This workbook is intended for children who are beginning to learn English as a second or foreign language. Its aim is to encourage pupils to learn the language as a means of communicating with the teacher and with each other. The stimulus is provided by games, and a variety of activities and picture puzzles, which, in motivating the pupil to find solutions, encourage him to practice the language used for making guesses, forming judgements, expressing agreement or disagreement, asking and answering questions, etc. Vocabulary and structures are systematically revised throughout the book. Each page has an oral and a written section. The Let’s Talk section provides model conversations for talking about the games and puzzles, and the Let’s Write section exercises to test what has been learnt orally.
