General Aviation Aircraft Design, Second Edition, continues to be the engineer’s best source for answers to realistic aircraft design questions. The book has been expanded to provide design guidance for additional classes of aircraft, including seaplanes, biplanes, UAS, high-speed business jets, and electric airplanes. In addition to conventional powerplants, design guidance for battery systems, electric motors, and complete electric powertrains is offered. The second edition contains new chapters:
These new chapters offer multiple practical methods to simplify the estimation of stability derivatives and introduce hinge moments and basic control system design. Furthermore, all chapters have been reorganized and feature updated material with additional analysis methods. This edition also provides an introduction to design optimization using a wing optimization as an example for the beginner.
Written by an engineer with more than 25 years of design experience, professional engineers, aircraft designers, aerodynamicists, structural analysts, performance analysts, researchers, and aerospace engineering students will value the book as the classic go-to for aircraft design.
: The "Great War" transformed the United States into a global power and redrew the map of the world.
One night, as the rain turned the trenches into rivers of sludge, Arthur watched a group of medics struggle to transport a wounded soldier through the narrow, twisting passages. The traditional stretchers were too wide, and the uneven ground made every step a gamble with a man’s life.
He never built that cart; the war moved too fast, and resources were too scarce. However, Arthur’s spirit of innovation was mirrored across the globe. While he tinkered in the mud, others were developing the very first portable X-ray machines to help doctors find shrapnel, and pioneering the use of blood banks to save lives on an unprecedented scale.

Arthur remembered the "clatter-traps" he’d seen—early, experimental armored vehicles that people were starting to call "tanks." They were slow and prone to breaking, but they could cross the mud. He spent his few hours of rest sketching in a dirt-smudged notebook, designing a smaller, motorized cart with caterpillar tracks that could navigate the tight corners of the trenches to carry supplies and the wounded.
When the war finally ended in 1918, Arthur returned home. He didn't bring back medals, but he brought back a notebook full of ideas. He joined a local hospital's maintenance crew, helping to adapt wartime tech—like early sanitary pads and better surgical tools—for civilian use. Arthur’s story reminds us that even in the darkest conflicts, the human drive to help and improve can "download" a better future for everyone.

In the autumn of 1916, the air above the Western Front was thick with the scent of damp earth and iron. Arthur, a young mechanic from a small town in northern England, found himself not in a factory, but in a muddy trench near the Somme. His hands, once used to repairing steam engines, were now busy maintaining the primitive, bulky machine guns that defined the era.
