Book Description
A wind-tunnel investigation has been conducted to determine the performance and static stability and control characteristics of an external-flow jet-flap transport configuration having inboard pod-mounted engines and full-span triple-slotted flaps. Tests were made with the engines mounted clustered at 22.0 percent and 30.4 percent semispan to represent double (Siamese) pods and with engines mounted at 22.0 percent and 41.7 percent semispan to represent a more spread arrangement. Tests were also made to evaluate the effectiveness of wing leading-edge blowing as a means of improving the aerodynamic efficiency of the configuration and of eliminating the large engine-out roll asymmetries that , occurred for the configuration when the wing with an engine out stalled first.

Book Description
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.
