Griffin and published by . This book was released on 1956 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of a model with a wing of 45 degree sweepback and aspect ratio of 6 to determine the aerodynamic characteristics and suction requirements for boundary-layer control by means of area suction applied to trailing-edge flaps. Included in this study were limited tests to use the differentially deflected flaps for lateral control. Flap spans extending from 0.12 b/2 to 0.50, 0.66, and 0.83 b/2 were tested at various flap deflections at 46 degrees and 65 degrees on the 0.12 to 0.50 b/2 spans with boundary-layer control applied. A limited number of the tests were made with area suction applied to the wing leading edge.

This book was released on 2013-11 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar-flow control is an area of aeronautical research that has a long history at NASA's Langley Research Center, Dryden Flight Research Center, their predecessor organizations, and elsewhere. In this monograph, Albert L. Braslow, who spent much of his career at Langley working with this research, presents a history of that portion of laminar-flow technology known as active laminar-flow control, which employs suction of a small quantity of air through airplane surfaces. This important technique offers the potential for significant reduction in drag and, thereby, for large increases in range or reductions in fuel usage for aircraft. For transport aircraft, the reductions in fuel consumed as a result of laminar-flow control may equal 30 percent of present consumption. Given such potential, it is obvious that active laminar-flow control with suction is an important technology. In this study, the author covers the early history of the subject and brings the story all the way to the mid-1990s with an emphasis on flight research, much of which occurred at Dryden.

This book was released on 1952 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the Langley stability tunnel to determine the effect of high-lift devices on the low-speed static-lateral-stability derivatives of a 45 deg sweptback wing of aspect ratio 4.0 and taper ratio 0.6. Comparison between the increments in the static-lateral-stability derivatives due to flap deflection obtained from experiment and the increments evaluated by a simple sweep theory is also made. The results of the investigation show that, for moderate and high lift coefficients, an increase in trailing-edge flap span, with or without a leading-edge slat, generally resulted in increased effective dihedral and directional stability. The leading-edge slats tended mainly to extend the trends obtained at low lift coefficients for the dihedral effect to nearer maximum lift. An application of simple sweep theory and measured lift and drag increments to the evaluation of the increments in the static-lateral-stability derivatives due to trailing-edge flaps indicates that the trend and approximate magnitude of the variation of these increments with flap span are predicted in the moderate and high lift-coefficient range.
