This book was released on 1965 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to study the effects of aspect ratio and canopy shape on the static longitudinal and lateral aerodynamic characteristics of parawings having 50.0° sweptback leading edges. Parawings with conical canopies and aspect ratios of 3.00, 4.00, 5.00, and 5.45 and parawings with cylindrical (zero twist and camber) canopies and aspect ratios of 3.00, 4.00, and 5.45 were used in the investigation. Effects of canopy fullness were investigated for aspect-ratio-5.45 parawings with both conical and cylindrical canopies.

This book was released on 1964 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low-speed wind-tunnel investigation was conducted to study effects of wing-canopy shape on the aerodynamic characteristics and spreader-bar load of a 550 swept parawing having large-diameter leading edges and keel. The canopy-flat-pattern sweep angles investigated on the 550 swept wing were 42.50, 450, 47.50, 500, and 52.50. Several other modifications to the canopy shape were also studied, such as removal of single, double, and compound gores from the rear part of each canopy lobe. A study of the effects of wing-leading-edge sweep angle was made between sweep angles of 500 and 600 and effects of leading-edge diameter were obtained at the basic 550 sweep angle. Effects of keel web height were determined for a constant trailing-edge length and also for trailing-edge lengths that varied with web height.

Naeseth and published by . This book was released on 1963 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the Langley 300-MPH 7- by 10-foot tunnel to determine the aerodynamic characteristics of a related series of parawings in which wing sweep was the primary variable. The leading-edge sweep angles varied from 400 to 750 and the three basic parawings had flat-planform sweep angles of 350, 450, and 550. The canopies of the wings were made of fabric. Tests were made at an airspeed of 38.6 mph and a Reynolds number of approximately 1.5 X 106. The maximum angle-of-attack range was from 140 to 530 for the wings having a canopy of 350 flat-planform sweep. A limited investigation of lateral characteristics was made for sideslip angles from approximately -50 to 160 for two angles of attack, and lateral stability derivatives were obtained for some configurations through a angle-of-attack range. Forces and moments acting on the wing and apex hinge moments were measured.

Book Synopsis Experimental and Theoretical Studies of the Effects of Camber and Twist on the Aerodynamic Characteristics of Parawings Having Normal Aspect Ratios of 3 and 6 by : Edward Charles Polhamus
Download or read book Experimental and Theoretical Studies of the Effects of Camber and Twist on the Aerodynamic Characteristics of Parawings Having Normal Aspect Ratios of 3 and 6 written by Edward Charles Polhamus and published by . This book was released on 1963 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-speed wind-tunnel studies were made of the effects of camber and twist and the effects of aspect ratio on the aerodynamic characteristics of parawings. To determine the effects of camber and twist, tests were made both with the conventional conical-type canopy, which provides camber and washout, and with a cylindrical-type canopy which provides essentially zero camber and twist. With regard to aspect ratio, tests were made of parawings having aspect ratios of 3 and 6; the range was thereby extended well beyond that of previous investigations. The degree to which airfoil and wing theory can be used to predict the aerodynamic characteristics of parawings was also investigated.

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 1965 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Part IV of a general para ing study, low-speed measurements have been made of the aerodynamic characteristics of triangular one-lobed and two-lobed parawings of aspect ratios 1, 2, and 3 for comparison with the theory of Parts I and II of the study. It was found that this theory is adequate for determining the canopy shapes, the luffing boundaries, and the lift characteristics for parawings of low to moderate slackness ratio. The measured center of pressure positions are slightly forward of the theoretical position as a result, it is thought, of the presence of the leading-edge members. Also, the aerodynamic design of the leading-edge members is such that from 20 percent to 70 percent of the theoretical leading-edge suction is realized. The maximum lift-drag ratios appear to be adversely affected by trailing-edge flutter which in some cases is so intense as to preclude aerodynamic testing at angles of attack for maximum lift-drag ratio. A parawing of aspect ratio 8.5 with a taut trailing-edge cable exhibited no flutter, and when the tension was relieved the flutter was intense and the maximum lift-drag ratio actually increased.
