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.

Book Synopsis Gust-tunnel Investigation of a Wing Model with Semichord Line Swept Back 60 Degrees by : Harold B. Pierce
Download or read book Gust-tunnel Investigation of a Wing Model with Semichord Line Swept Back 60 Degrees written by Harold B. Pierce and published by . 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.

Book excerpt: The results of tests made in the Langley gust tunnel on a 30 degree sweptback-wing model indicate within the scope of the data and the values of gradient distance investigated, the maximum acceleration increment depends on the slope of the lift curve of the equivalent straight wing multiplied by the cosine of the angle of sweep and on the effect of gradual penetration of the sweptback wing into a gust.

Available in PDF, EPUB and Kindle. Book excerpt: A series of tests of a 45 degree swept-back 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 the sweep, rather than on the steady-flow slope of the lift curve.

Book Synopsis Low-speed Static Wind-tunnel Investigation of a Half-span Fuselage and Variable-sweep Pressure Wing Model by : John E. Lamar
Download or read book Low-speed Static Wind-tunnel Investigation of a Half-span Fuselage and Variable-sweep Pressure Wing Model written by John E. Lamar and published by . This book was released on 1971 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experimental balance and pressure data obtained from tests of an untwisted variable-sweep wing with an outboard pivot exhibited nonlinearities in both total normalforce-coefficient and pitching-moment-coefficient curves for all sweep angles and fuselage conditions. These total effects have been traced back through the section data and pressure distributions to find the causes. The causes of these nonlinearities were found to be (1) separation of flow on the outer panel and (2) a leading-edge vortex flow on the inner panel. A fuselage added to the wing had little effect on the aerodynamic characteristics. Predictions of wing loadings and performance characteristics were made by using the modified Multhopp method and a comparison with experimental results indicated reasonable agreement. The changes in span loading as a result of leading-edge shed-vortex formation and flow separation at the higher angles of attack caused an increase in the induced-drag parameter.
