Excerpt from The Mechanical Principles of the Aeroplane
Mathematically speaking, we can calculate the force exerted by the fluid on the body by adding up vectorially the pressures on the various parts of the exposed surface. But this is generally of little help to us, because in most cases we are quite ignorant of the pressures. Set up in the fluid. But of one thing we can be certain a priori, namely, that the exerted by a fluid on an immersed body when there is relative motion is in the nature a resistance, tending to reduce the relative motion. This is the inference derived from such ordinary experiences as walking against a wind, or trying to keep a boat still in a current of water.

Leopold Classic Library is delighted to publish this classic book as part of our extensive collection. As part of our on-going commitment to delivering value to the reader, we have also provided you with a link to a website, where you may download a digital version of this work for free. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. Whilst the books in this collection have not been hand curated, an aim of our publishing program is to facilitate rapid access to this vast reservoir of literature. As a result of this book being first published many decades ago, it may have occasional imperfections. These imperfections may include poor picture quality, blurred or missing text. While some of these imperfections may have appeared in the original work, others may have resulted from the scanning process that has been applied. However, our view is that this is a significant literary work, which deserves to be brought back into print after many decades. While some publishers have applied optical character recognition (OCR), this approach has its own drawbacks, which include formatting errors, misspelt words, or the presence of inappropriate characters. Our philosophy has been guided by a desire to provide the reader with an experience that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic book, and that the occasional imperfection that it might contain will not detract from the experience.

Vendeur : Forgotten Books, London, Royaume-Uni
Paperback. Etat : New. Print on Demand. This book is a groundbreaking exploration of the scientific principles behind flight, specifically focusing on the aerodynamics and mechanics of heavier-than-air machines. Written at a time when aviation was in its infancy, the author delves into the fundamental concepts of motion, resistance, and stability, grounding his analysis in the emerging fields of aerodynamics and rigid dynamics. The book addresses crucial questions that were at the forefront of aviation research at the time, such as the optimal shape of wings, the role of viscosity and elasticity in air resistance, and the challenges of achieving stable and controlled flight. The author also explores the significance of the propeller, the heart of early aircraft propulsion, examining its design and function within a broader understanding of the dynamics of flight. By meticulously dissecting the complex interactions between an aircraft and the air it traverses, the book provides a comprehensive and insightful framework for understanding the fundamental principles governing flight, offering a valuable historical perspective on the evolution of aeronautical science.
