Available in PDF, EPUB and Kindle. Book excerpt: The results of tests made in the Langley gust tunnel on a 45 deg swept- forward-wing model show that the acceleration increment obtained in a gust can be satisfactorily predicted from a slope of the lift curve obtained by multiplying the slope of the lift curve of the equivalent straight wing by the cosine of the angle of sweep and by using strip theory to estimate the penetration effect.

Book Synopsis Gust-tunnel Investigation of a Flexible-wing Model with Semichord Line Swept Back 45° by : Thomas D. Reisert

This book was released on 1949 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley gust tunnel of a flexible-wing model with the semichord line swept back 45 degrees to obtain experimental data on the amount of gust-load alleviation that might be expected as a result of the wings flexing under load. The results indicated that unless adverse pitching motion could be eliminated or reduced the over-all load reduction would be small. The net reduction in bending moment, however, may be appreciable.

This book was released on 1950 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley gust tunnel of a 60 degree sweptback-wing model to determine its response to gusts. On the basis of results, a simplified method of analysis, which uses a slope of the lift curve derived by the cosine law and which uses strip theory to estimate the penetration effect, appears to be applicable for the prediction of gust loads on wings swept as much as 60 degrees.

Download or read book Tests of a 45 Deg Sweptback-Wing Model in the Langley Gust Tunnel written by and published by . This book was released on 1948 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of tests of a 45 deg sweptback-wing model with and without fuselage and of an equivalent straight-wing model were conducted in the Langley gust tunnel to provide information on some of the problems encountered in the prediction of gust loads for airplanes incorporating swept wings. A comparison of test results with calculated results indicated that the maximum acceleration increment resulting from the penetration of a gust by a sweptback-wing airplane may be assumed to be dependent on the slope of the lift curve of the equivalent straight wing multiplied by the cosine of the angle of sweep, rather than on the steady flow slope of the lift curve. In addition, it appeared that the maximum acceleration increment also depends on the effect on the unsteady-lift function of the gradual penetration of the sweptback wing into the gust. A comparison of the maximum acceleration increments obtained for the swept-wing model with those obtained for the straight-wing model indicated that, although the airplane with a swept wing would show positive pitching motion, it would undergo a much lower acceleration increment than the same airplane with the equivalent straight wing.
