The book bridges the gap between complex mathematical theory and the hands-on practice of building and flying.
By eliminating the horizontal tail (and sometimes the vertical fin entirely), tailless aircraft aim to achieve several major theoretical advantages:
The most famous practical application of tailless theory is Jack Northrop’s series of flying wings: the N-1M, N-9M, and the YB-49 bomber. These aircraft demonstrated the theoretical benefits—low drag, high lift-to-drag ratio, and large internal volume. However, they also exposed the gap between theory and practice. The YB-49 suffered from at high angles of attack and aerodynamic “porpoising” in pitch. These issues, documented in declassified PDF reports, eventually led to the program’s cancellation in favor of conventional bombers.
In conventional aircraft, the tail serves two primary purposes: and control . The horizontal stabilizer acts like a weather vane, keeping the nose pointed into the wind, while the elevator controls pitch. To remove the tail, these functions must be integrated into the main wing. The Drag Benefit
By sweeping the wings backward, the outer sections act as a lever arm. When combined with tip washout —reducing the angle of incidence toward the wingtips—these tips function as a built-in tailplane, providing the necessary downward force to keep the nose level.
"The required computation is beyond analog or digital systems," Volkov wrote. "Only the human vestibular system, in a state of deliberate vertigo, can ride the rebound. The pilot must unlearn the instinct to correct."
Aris stared at the paper. Outside his window, the sky was a deep, bruised purple. He had a barn workshop, a half-built tailless drone he’d been tinkering with for a decade, and a stubborn refusal to believe that a 50-year-old PDF could change anything.
For students, researchers, and hobbyists, the search term is a gateway to a crucial body of knowledge. This article explores the core principles of tailless design, the historical milestones, and where to find authoritative PDF resources that bridge the gap between aerodynamic theory and practical flight.
