If you are searching for a specific PDF by that title, here is what a comprehensive, high-quality document should contain. Be wary of short blog posts; a true "theory and practice" document is likely a textbook chapter, a graduate-level lecture note, or an AIAA (American Institute of Aeronautics and Astronautics) paper.
More than three decades after its original publication, Tailless Aircraft in Theory and Practice remains the most comprehensive English-language reference on the subject. Its unique blend of rigorous mathematics and practical flight experience, its systematic treatment of both aerodynamic theory and real-world design considerations, and its prescient coverage of then-emerging technologies like the B-2 "Stealth Bomber" ensure its continued relevance.

One particularly forward-looking PDF is "Tailless Aircraft for Mars Flight" (AIAA Journal, 2024), which discusses how low-density atmospheres make tail surfaces draggy and inefficient, making tailless designs the only viable choice for planetary aerial exploration.
The keyword "theory" in your PDF search refers to the fundamental aerodynamic instability that plagues tailless designs. A conventional aircraft is stable because the tail provides a restoring moment. A tailless aircraft must achieve stability and control using only the wing. This creates three critical challenges: If you are searching for a specific PDF
The pursuit of aerodynamic efficiency has long driven aircraft designers to eliminate components that create parasitic drag. Among these, the conventional tail assembly—with its horizontal stabilizer, elevators, and vertical fin—has been a recurring target for removal. The book , written by German aerodynamicist Karl Nickel and designer-builder Michael Wohlfahrt and translated into English by renowned test pilot Captain Eric M. Brown, stands as the definitive English-language reference work on this subject.
The book is sometimes summarized in:
Early pioneers proved the viability of the concept. In 1910, British Army Officer J. W. Dunne successfully flew the Dunne D.5, a tailless biplane with swept wings designed for inherent stability. Almost simultaneously, German engineer Hugo Junkers received a patent for his "Nurflügel" (flying wing) concept.
