Download or read book Effect of Sweepback and Aspect Ratio on Longitudinal Stability Characteristics of Wings at Low Speeds written by Joseph A. Shortal and published by . This book was released on 1946 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the interest in swept-back wings for high-speed airplanes an analysis has been made of readily available data on the longitudinal stability characteristics of swept-back wings at low-speeds. The analysis indicated that the shape of the pitching-moment curve near the stall for swept-back wings is greatly dependent upon the aspect ratio. A chart has been prepared relating aspect ratio and sweepback that indicates the combinations of aspect ratio and sweepback necessary to obtain stability near the stall for wings alone. The effect of the addition of a horizontal tail behind a swept-back wing may be destabilizing and requires further investigation.

Book Synopsis Influence of Large Amounts of Wing Sweep on Stability and Control Problems of Aircraft by : Hartley Akin Soule
Download or read book Influence of Large Amounts of Wing Sweep on Stability and Control Problems of Aircraft written by Hartley Akin Soule and published by . This book was released on 1946 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of large amounts of sweep has been suggested in this country and in Germany as a means of avoiding some of the drag increase and stability and control difficulties encountered in high-speed flight with conventional straight-wing airplanes. Experience with sweep in tailless airplanes and studies made since this suggested has been made have indicated that the use of a large amount of sweep will, in itself, introduce stability and control problems of sufficient magnitude and complexity to require considerable research, particularly for flight at high angles of attack. The paper discusses these problems and, although no proved solutions are given, in some cases promising lines for further investigation are presented.
Book Synopsis Lift, Pitching Moment, and Span Load Characteristics of Wings at Low Speed as Affected by Variations of Sweep and Aspect Ratio by : Edward J. Hopkins
Download or read book Lift, Pitching Moment, and Span Load Characteristics of Wings at Low Speed as Affected by Variations of Sweep and Aspect Ratio written by Edward J. Hopkins and published by . 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.

This book was released on 1959 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air-flow characteristics behind wings and wing-body combinations are described and are related to the downwash at specific tail locations for unseparated and separated flow conditions. The effects of various parameters and control devices on the air-flow characteristics and tail contribution are analyzed and demonstrated. An attempt has been made to summarize certain data in a form useful for design. The experimental data herein were obtained mostly at Reynolds numbers greater than 4 x 105 and at Mach numbers less than 0.25.

Book Synopsis Analysis of Wind-tunnel Tests to a Mach Number of 0.90 of a Four-engine Propeller-driving Airplane Configuration Having a Wing with 40 Degrees Sweepback and an Aspect Ratio of 10 by : George G. Edwards
Download or read book Analysis of Wind-tunnel Tests to a Mach Number of 0.90 of a Four-engine Propeller-driving Airplane Configuration Having a Wing with 40 Degrees Sweepback and an Aspect Ratio of 10 written by George G. Edwards and published by . This book was released on 1956 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted at speeds up to a Mach number of 0.90 to determine the effects of operating propellers on the longitudinal characteristics of a four-engine tractor airplane configuration having a 40 degrees swept wing with an aspect ratio of 10. Results of wind-tunnel tests of a model representing such an airplane configuration (see NACA TN 3789) show that these effects are of most concern in the low-speed high-thrust flight regime. In the present report the low-speed data are analyzed to determine the source of the various effects and to indicate how the adverse effects can be reduced, and the high-speed data are discussed primarily from the standpoint of Mach number effects. The analysis of the low-speed data indicates that the large variations of longitudinal stabil.itywith angle of attack resulted primarily from passage of the tail into and out of the slipstream. The slipstream also created large lift increments on the wing, particularly with flaps deflected, which resulted in increases in stability (with increasing thrust coefficient) from the outboard propeller and decreases in stability from the inboard propeller. It was concluded that the longitudinal stabiltty characteristics of the model couldbe improved by moving the nacelles outward, increasing the tail height, and reducing the tail span.
