He towed the craft to the ridge. It had no tail, no rudder, just a wide, silent wing like a manta ray. He strapped in. The control stick felt loose, disconnected. He remembered Volkov’s warning: "Do not fly the aircraft. Listen to it. When it wants to fall, let it fall. When it wants to turn, do not say no."

Introduction: The Allure and Challenge of Tailless Flight For over a century, aircraft designers have sought to eliminate the conventional tail assembly. In standard aviation architecture, the horizontal stabilizer and vertical fin act as a necessary evil. They provide stability and control, but they also generate parasitic drag, add structural weight, and increase radar cross-section.

During the 1930s and 1940s, Reimar and Walter Horten pioneered the pure flying wing. Their Horten Ho 229 jet fighter-bomber utilized severe wing sweep and a bell-shaped lift distribution. By reducing span loading to zero at the wingtips, they eliminated adverse yaw mechanically, bypassing the need for a vertical tail fin. Jack Northrop (Northrop YB-49)

The absence of an aft tail dramatically shortens the control moment arms of the aircraft. Consequently, the control surfaces must be highly integrated, multifunctional, and precisely modulated. Control Surface Configurations

Then the vertigo hit.

By sweeping the wings backward, the wingtips are positioned well behind the vehicle's CG, acting as a short tailplane. By combining this sweep with washout (twisting the wing so the outer tips have a lower angle of attack than the root), the tips produce less lift—or even negative lift—relative to the root. This configuration generates the necessary nose-up pitching moment to trim the aircraft. Lateral and Directional Stability He towed the craft to the ridge

What makes this book so special is the unique collaboration of its authors. The text is the result of a long-term partnership between a mathematician and a designer, builder, and pilot of tailless sailplane models.

The removal of the vertical tail fin yields massive benefits for stealth and profile drag, but eliminates inherent directional (yaw) stability. Tailless flying wings use specialized mechanical drag devices for yaw authority:

He was not flying. He was sinking upward.

Smooth, integrated profiles without vertical fins are ideal for stealth.

Tailless Aircraft in Theory and Practice by Karl Nickel and Michael Wohlfahrt (published in 1994 by AIAA) is widely considered the for enthusiasts and designers.

The advent of digital computer technologies in the late 20th century transformed tailless aircraft design from an unstable theoretical ideal into an operational reality. Fly-By-Wire (FBW) Systems
