Tailless Aircraft in Theory and Practice is a seminal book by Karl Nickel Michael Wohlfahrt

" by Karl Nickel and Michael Wohlfahrt. This guide synthesizes their principles with modern aerodynamic research to provide a complete overview of tailless design. 1. Fundamental Theory of Tailless Design

Reflexed Airfoils: Use of trailing edges that curve upward to produce a positive pitching moment.

If you need the technical content without the PDF:
The book is sometimes summarized in:

: Traditional tails and fuselages create drag without producing lift. Reduce Weight

Broad Design Range: Coverage spans from radio-controlled (RC) models and hang gliders to full-scale powered aircraft, including significant historical designs like the Horten brothers' flying wings and the U.S. Stealth Bomber.

2. Static Longitudinal Stability

The book provides the mathematical derivation for the Static Margin.
