This book was released on 1930 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to give the large-scale characteristics of a variety of airfoils in a form which will be of maximum value, both for airplane design and for the study of airfoil characteristics, a collection has been made of the results of airfoil tests made at full-scale values of the Reynolds Number in the variable density wind tunnel of the National Advisory Committee for Aeronautics. They have been corrected for tunnel wall interference and are presented not only in the conventional form but also in a form which facilitates the comparison of airfoils and from which corrections may be easily made to any aspect ratio. An example showing the method of correcting the results to a desired aspect ratio has been given for the convenience of designers. In addition, the data have been analyzed with a view to finding the variation of the aerodynamic characteristics of airfoils with their thickness and camber.

This book was released on 1933 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of a large group of related airfoils was made in the N.A.C.A. variable-density wind tunnel at a large value of the Reynolds Number. The tests were made to provide data that may be directly employed for a rational choice of the most suitable airfoil section for a given application. The variation of the aerodynamic characteristics with variations in thickness and mean-line form were therefore systematically studied.

Book excerpt: The effects of scale and turbulence on the lift and drag of five airfoils, the N.A.C.A. 0006 , the N.A.C.A. 0021, the Clark Y, The U.S.A 35-A, and the U.S.N. P.S.6, hve been investigated in the Variable Density Wind Tunnel. Tests were made over a wide scale for only two different conditions of turbulence.

Available in PDF, EPUB and Kindle. Book excerpt: These tests show that small changes in airfoil contours, resulting from variations in the specified ordinates, have a sufficiently large effect upon the airfoil characteristics to justify the taking of great care in the specification of ordinates for the construction of models.

Download or read book The Aerodynamic Characteristics of Six Commonly Used Airfoils Over a Large Range of Positive and Negative Angles of Attack written by Raymond F. Anderson and published by . This book was released on 1931 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results of tests of six commonly used airfoils: The M-6, the CYH, the N-22, the C-72, the Boeing 106, and the Gottingen 398. The lifts, drags, and pitching moments of the airfoils were measured through a large range of positive and negative angles of attack in the Variable Density Wind Tunnel. For the N-22, the C-72, the Boeing 106, and the Gottingen 398 airfoils, the negative maximum lift coefficients were found to be approximately half the positive; but for the M-6 and CYH, which have less effective camber, the negative values were, respectively, 0.8 and 0.6 of the positive values.
