Book Synopsis Investigation of Drag Reduction by Boundary Layer Suction on a 50-deg Swept Tapered Wing at M (free-stream) by : S. R. Pate
Download or read book Investigation of Drag Reduction by Boundary Layer Suction on a 50-deg Swept Tapered Wing at M (free-stream) written by S. R. Pate and published by . This book was released on 1964 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the 40-in. supersonic Tunnel A of the von Karman Gas Dynamics Facility to determine the effectiveness of boundary layer suction for laminar flow control on a tapered, three-dimensional, 50-deg swept supersonic wing. Test Mach numbers were 2.5, 3, 3.5, and 4 with a Reynolds number range (based on boundary-layer rake location) from 4.3 to 19.5 million for angles of attack of zero and =3 deg. Wake drag, suction drag, and total drag coefficients and the corresponding suction coefficients are presented, along with fully turbulent wake drag coefficients for the no-suction case.

This book was released on 2013-06-29 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: ------------------------------------------------------------ This volume contains the Proceedings of the CEAS/DragNet European Drag Reduction Conference held on 19-21 June 2000 in Potsdam, Germany. This conference, succeeding the European Fora on Laminar Flow Technology 1992 and 1996, was initiated by the European Drag Reduction Network (DragNet) and organised by DGLR under the auspice of CEAS. The conference addressed the recent advances in all areas of drag reduction research, development, validation and demonstration including laminar flow technology, adaptive wing concepts, turbulent and induced drag reduction, separation control and supersonic flow aspects. This volume which comprises more than 40 conference papers is of particular interest to engineers, scientists and students working in the aeronautics industry, research establishments or academia.

Book Synopsis A Numerical Study of Novel Drag Reduction Techniques for Blunt Bodies in Hypersonic Flows by : Christopher David Marley
Download or read book A Numerical Study of Novel Drag Reduction Techniques for Blunt Bodies in Hypersonic Flows written by Christopher David Marley and published by . This book was released on 2011 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Numerical simulations of a full three-dimensional hemispherical body in hypersonic flow are conducted and innovative techniques involving forward injection of gas from the stagnation point of the sphere are investigated; techniques include annular (ring) and swirled injection both with and without upstream energy deposition. Objectives of the analysis are the assessment of 1) drag reductions achieved on the blunt body (including the detrimental drag effect caused by the forward-facing injection itself) and 2) stability characteristics of the jet. Studies are conducted at free-stream Mach numbers of 10 and 6.5 at standard atmospheric conditions corresponding to 30 km altitude. While centered forward injection without upstream energy deposition is confirmed to be highly unstable either with or without swirl, annular ring injection exhibits a stabilizing influence on the jet. Energy deposition upstream of the body is shown to significantly enhance stability and penetration of the forward injection jet for all techniques"--Abstract, p. iii.

This book was released on 1963 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the 40-Inch Supersonic Tunnel (A) of the von Karman Gas Dynamics Facility to determine the effectiveness of boundary layer suction for laminar flow control on a two-dimensional, 72.5-deg swept wing having a subsonic leading edge. Test Mach numbers were 2 and 2.25 with a Reynolds number range based on wing chord from 3 to 14 million for angles of attack of 0.15, 0.45, and 0.75 deg. With suction, full chord laminar flow was maintained at M 2, alpha 0.15, 0.45, and 0.75 deg up to a length Reynolds number of approximately 9 million. At M 2.25 and alpha 0.15 deg, full chord lam inar flow was maintained up to a Reynolds number of 6.5 x 10 to the 6th power and for alpha 0.45 and 0.75 deg, up to a Reynolds number of 3 x 10 to the 6th power. Selected data are presented.
