Available in PDF, EPUB and Kindle. Book excerpt: High-fidelity multidisciplinary analysis capabilities for the prediction and control of tail buffeting of fighter aircraft have been developed and extensively validated for the F/A-18 aircraft. The computational results compared very well with flight and several experimental data. The results indicated that the vertical tail is subject to both bending and torsional responses, mainly in the first mode. The buffet excitation peaks shift to lower frequency as the angle of attack increases. Capabilities for buffet alleviation have been demonstrated using LEX fences and vortical blowing. A parametric study for both the active and passive flow control has been conducted. Capabilities for actively controlling the vertical tail structure have been demonstrated by strengthening the F/A-18 vertical tail using piezoelectric actuators.

Book excerpt: Established in 1917 as the nation#s first civil aeronautics research laboratory under the National Advisory Commit-tee for Aeronautics (NACA), Langley was a small laboratory that solved the problems of flight for military and civil aviation. Throughout history, Langley has maintained a working partnership with the Department of Defense, U.S. industry, universities, and other government agencies to support the defense of the nation with research. During World War II, Langley directed virtually all of its workforce and facilities to research for military aircraft. Following the war, a balanced program of military and civil projects was undertaken. In some instances Langley research from one aircraft program helped solve a problem in another. At the conclusion of some programs, Langley obtained the research models for additional tests to learn more about previously unknown phenomena. The data also proved useful in later developmental programs. Many of the military aircraft in the U.S. inventory as of late 1999 were over 20 years old. Langley activities that contributed to the development of some of these aircraft began over 50 years prior. This publication documents the role, from early concept stages to problem solving for fleet aircraft, that Langley played in the military aircraft fleet of the United States for the 1990's.
