This book was released on 1951 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of untapered, unswept, complete wings of apsect ratios 1.13, 2.13, 4.13, and 6.13 was investigated at a Mach number of 0.26 to determine the effect of aspect ratio on the lateral control characteristics of the wings equipped with 0.25-chord sealed ailerons of various spans and of various spanwise locations. Design charts are presented for computing aileron effectiveness of low-aspect-ratio, untapered, unswept wings.

This book was released on 1951 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low-speed wind-tunnel investigation was made to determine the lateral control characteristics of three untapered unswept wings of aspect ratio 1.13, 2.13, and 4.13 and an untapered 4%o sweptback wing of aspect ratio 2.09 equipped with O.60-semispan retractable ailerons having various projections. Each of the wings had an NACA 64A010 airfoil section and had the ailerons mounted at the 0. 70-chord station. The continuous- span aileron investigated on the unswept wings spanned the outboard stations of each wing; whereas the plain (continuous span) and stepped (segmented) retractable ailerons investigated on the sweptback wing were located at various spanwise stations and were tested with and without simulated actuating arms.

This book was released on 1951 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lift, pitching-moment, and pressure distribution were measured on a wing which was swept -40, -30, 0, 35, and 45 degrees. The wing span was decreased to give aspect ratios 6.8, 5.3, 4.2, 3.4, and 2.8. The effects of independent variations of sweep and aspect ratio on the lift, pitching-moment, and span-load characteristics of the wings are compared with the effects estimated by use of the Weissinger method.

Book excerpt: A wind-tunnel investigation was made at low speed to determine the lateral control characteristics of a 51.3 degrees sweptback-wing model equipped with either plain or stepped spoiler ailerons having a fixed projection of 5-percent-wing chord and various spans and spanwise locations. The spoiler-aileron configurations were tested on the wing alone, on the wing with a simulated fuselage, on the wing with a simulated fuselage and either a 0.487-span outboard drooped nose, a 0.487-span inboard split flap, or a combination of the two devices.

This book was released on 1950 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A free-flight-tunnel investigation has been made to compare the dynamic lateral control characteristics provided by step plug ailerons on a sweptback-wing model having full-span flaps. The model had a 38 degree sweptback wing with an aspect ratio of 3 and a taper ratio of 0.05. The static stability and control characteristics of the flight-test model were determined from force tests and the time-lag characteristics of the ailerons were determined from stand tests in which there was freedom only in roll. Flight tests of the model were made over a range of lift coefficient from 1.0 through the stall.

Book excerpt: The trends in lateral stability and control produced variations of the mass distribution were determined for a model with a 45 degree sweptback wing. Calculations were made to correlate the trends determined by theory with those determined from tests of a free-flying dynamic model in the Langley free-flight tunnel.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley 300 mph 7- by 10-foot tunnel to determine the effects of various sizes and shapes of end plates on the aileron characteristics and on the aerodynamic characteristics in pitch and yaw of a wing of aspect ratio 2, no taper, and a sweepback of 45 degrees and a wing of aspect ration 4, taper ratio 0.6, and a sweepback of 46.7 degrees. Free-roll characteristics were obtained with two end-plate configurations on a wing aspect ratio 3, taper ratio 0.6, and a sweepback of 35 degrees in order to determine the effect of end plates on wing damping in roll.

This book was released on 1953 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the finite-span effects on the local loading characteristics of two sweptback wings at low speed has been made with a view toward providing some insight into the usefulness of two-dimensional section data and span-loading theory for determining the characteristics of sections of a swept wing. The two wings considered, for which complete pressure-distribution data were available at large scale, were identical in plan form having 45 degrees of sweepback and an aspect ratio of 6 and differed in twist in sections, the latter being the NACA 64A010 and NACA 64A810.

Naeseth and published by . This book was released on 1954 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low-speed wind-tunnel investigation was made to determine the static lateral control characteristics of flap-type and retractable spoiler-type ailerons on a rigid sweptback wing, a flexible sweptback wing, and a flexible M-wing. A few tests were also made with a half-delta tip control on the flexible sweptback wing. The semispan wing models were of aspect ratio 6.0, taper ratio of 0.6, and had NACA 65A009 airfoil sections parallel to the free-stream direction. The quarter-chord lines of the wings were swept 45 degrees and the break in the M-wing was at the half semispan location.

Download or read book Effect of Linear Spanwise Variations of Twist and Circular Arc Camber on Low Speed Static Stability Rolling and Yawing Characteristics of a 45 Degrees Sweptback Wing of Aspect Ratio 4 and Taper Ration 0 6 written by and published by . This book was released on 1952 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation at low scale has been made in the Langley stab unity tunnel in order to determine the effect of linear spanwise variations of twist and circular-arc camber on the low-speed aerodynamic characteristics and static-stability and rotary-stability (rolling and yawing) derivatives of a wing of aspect ratio 4, taper ratio 0.6, and with 45 deg sweepback of the quarter-chord line. Results of the investigation indicate that twist or camber produced only small changes in the maximum lift coefficient. A combination of camber and twist was more effective than twist alone in providing an increase in the maximum lift-to-drag ratio in the moderate lift-coefficient range for the wings investigated. The variation of static longitudinal stability through the lift-coefficient range was less for the twisted wing than for the twisted and cambered or plane wing. A combination of twist and camber generally extended the initial linear range of several of the static- and rotary-stability derivatives to a higher lift coefficient and, although these effects were small, higher Reynolds numbers may result in larger effects.
