Similarly, modern UAVs like the and the RQ-170 Sentinel rely on the same principles. For today’s engineer, the PDF resources from the B-2’s development—particularly those detailing relaxed static stability and control law design—are essential reading.
). Without a tail to counteract this, a tailless aircraft will pitch down into an unrecoverable dive unless specific design remedies are implemented. 3. Stability and Control Theory
Conventional aircraft rely on the vertical fin to act like a weather vane, keeping the nose pointed into the relative wind. Without a vertical fin, a tailless aircraft exhibits neutral or negative static directional stability ( Practical Engineering Solutions for Yaw Control tailless aircraft in theory and practice pdf
: Traditional tails and fuselages create drag without producing lift. Reduce Weight
No discussion of this field is complete without Reimar and Walter Horten. Their goal was to create a flying wing so aerodynamically clean it generated almost no drag at all, requiring less engine power to achieve higher speeds and consuming less fuel. Their Ho 229, developed in the final years of World War II, remains one of the most radical fighter concepts ever built. Similarly, modern UAVs like the and the RQ-170
"Tailless Aircraft in Theory and Practice" by Karl Nickel and Michael Wohlfahrt serves as a comprehensive technical reference for designing and flying tailless aircraft, covering stability, control, and aerodynamic advantages such as reduced drag. The text bridges theoretical aerodynamics with practical application, addressing both longitudinal stability and yaw control mechanisms. For more details, visit Google Books ResearchGate
The book can be found in the physical collections of numerous university libraries, including (Engineering Library Stacks: TL684.6 .N53 1994), Shinshu University in Japan, Wichita State University , and the University of Hertfordshire . WorldCat lists it as available in 957 libraries worldwide, a testament to its status as a standard reference. Without a tail to counteract this, a tailless
