How do airplanes work and move?
The best aviation textbook that explains the flight principles and structure of aircraft.

Anyone who sees an airplane as large as a building ascending into the sky is bound to have an instinctive sense of wonder and wonder.
At this time, countless questions fill our minds, but few people can answer them.
The structure and principles of airplanes are something I have never learned in school, and most of the books I can find are specialized textbooks that do not take the general public's level of understanding into account at all. Furthermore, the information available on the Internet, a vast ocean of information, is fragmented and distracting.
Finding consistently well-organized material is almost a given.

100 Key Knowledge to Understanding the Crystalline of Aeronautical Science

The author, a veteran pilot with 30 years of experience, wrote "Airplane Structure Textbook" with the goal of creating a systematic and well-organized aviation education book.
This book is written with the author's hope that the general public will be able to understand the operating principles and structure of airplanes without having to attend aviation school or a specialized aviation institute.
The author, who introduced passenger aircraft piloting from a general perspective in the 2016 『Airplane Piloting Textbook』, focused this time on explaining the structure and operating principles of an airplane rather than piloting techniques.
In particular, the author says he wrote the book focusing on the following points:
First, I made it so that it could be understood sensorily even if I couldn't explain it in detail.
To understand airplanes, it's good to know what lift is and how it's generated, but going too deep will only diminish your understanding.
The author explains the force of gravity as a reaction of air to make it more sensible.
This may not be a sufficient explanation for an expert, but it is enough for the average person to understand the principles of flight.

Second, we valued pictures and diagrams over complex and lengthy explanations.
The content and information that you must know are summarized and presented in pictures.
This book consists of a total of 100 items, and each item is well explained with pictures and diagrams.
Anyone with some knowledge can understand the entire contents of the book just by looking at the diagrams and graphs.

Third, rather than simply introducing related formulas, we used actual numbers to provide a realistic explanation.
When explaining the formulas for calculating lift and drag, the formula for calculating lift-to-drag ratio, maximum takeoff weight, or bypass ratio, I used actual examples of passenger aircraft operated in actual aviation settings.
For example, it shows the actual net thrust and total thrust calculated by comparing the early turbofan engines JT8D and GE90-115B.

Fourth, always think and explain using a close example.
When explaining thrust, the force that moves an airplane forward, a representative example is a balloon that moves forward by spraying air.
An airplane sucks in air, sends it backwards, and uses the reaction to generate thrust, and balloons fly through the air using the same principle as airplanes.

The 『Airplane Structure Textbook』, consisting of six chapters, covers various topics related to lift in Chapter 1, and examines the differences between aircraft and airplanes and their relationship to the speed of sound in Chapter 2.
The structure and principles of actual airplanes will be explored in detail starting in Chapter 3.
It explains in an interesting way the principles of an airplane, in which numerous devices are organically combined to operate.
Chapter 4 examines the structure of jet engines.
Learn how jet engines generate power and use real-world figures to calculate the magnitude of the force.
Chapter 5 describes aircraft operations and related figures.
When flying, various forces act on the airplane, and the relationship between each force and its magnitude are actually calculated.
The last six chapters cover safety measures for airplanes.
When designing and operating an aircraft, always assume the worst case scenario.
Because of this, there are a lot of safety measures in place, and since it is a matter of life and death, safety measures are also very important when understanding airplanes.

Easy and fast, but deep!
Pictures and diagrams that explain complex content in a concise manner

It is very difficult for the average person to understand airplanes in one go.
First of all, there is so much to know to understand what an airplane is.
You need to understand aerodynamics and know the roles and principles of numerous mechanical devices.
An airplane is a more complex machine than a car, made up of tens of thousands of parts.
The advantage of the "Airplane Structure Textbook" is that it allows the general public to understand complex aircraft relatively easily and quickly.
Key concepts are conveyed with clear explanations and illustrations, and difficult-to-understand concepts or formulas are introduced with appropriate examples and real-world cases.
This book, which aims to be a general education book, thoroughly answers the question of "why," and therefore can be easily understood by anyone with a basic knowledge of physics and mathematics.
If you read slowly, following the author's friendly explanations, you will find clear answers to many questions, such as how jet engines generate power, how airplanes land in conditions where there is no visibility, and how airplanes weighing hundreds of tons can stay aloft.
The author says that he hopes that through this book, many people will become interested in airplanes and that there will be at least one more person who likes airplanes.
If you've ever been curious about the structure and principles of airplanes, the "Airplane Structure Textbook" will be of great help.
