Download or read book Wind tunnel Investigation of Paraglider Models at Supersonic Speeds written by Robert T. Taylor and published by . This book was released on 1961 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley Unitary Plan wind tunnel to determine the behavior of paraglider models at moderate to high supersonic speeds. The models were deployed from a sting in the supersonic stream and steady-state aerodynamics performance data were obtained. Maximum values of the lift-drag ratio were about 1.4 at a Mach number of 2.65 and about 1.2 at a Mach number of 4.65. The angles of attack over which the models could be flown were limited by unsteady behavior of the canopy.

Available in PDF, EPUB and Kindle. Book excerpt: A preliminary investigation of the aerodynamic and control characteristics of a flexible glider similar to a parachute in construction has been made at the Langley Research Center to evaluate its capabilities as a reentry glider. Preliminary weight estimates of the proposed vehicle indicate that such a structure can be made with extreamly low wing loading. Maximum temperatures during the reentry maneuver might be held as low as about 1,500 degrees F.

Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the 40-in. Supersonic Tunnel of the von Karman Gas Dynamics Facility to determine the aerodynamic characteristics of a series of flexible parachute models at Mach numbers from 1.5 to 3. Parachutes of various designs employing porous, non-porous, and ribbon materials were tested by deployment from a modified Pershing model. High-speed movies and drag measurements were obtained.

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.
