Download An Approximate Method of Calculating the Deformations of Wings Having Swept, M Or W, Lambda, and Swept-tip Plan Forms Book in PDF, ePub and Kindle
An approximate method of calculating the deformation of wings of uniform thickness having swept, M or W, Lambda, and swept-tip plan forms is presented. The method employs an adjustment to the elementary beam theory to account for the effect of the triangular root portion portion of a swept wing on the deformation of the outboard section of the wing. To demonstrate the general applicability of the method, the modified elementary theory is applied to the more comples M or W, Lambda, and swept-tip plan forms as well as to swept plan forms. For the purpose of calculating angles of attack, it is shown that the unmodified elementary beam theory applied to that part of the wing outboard of the root triangle produces satisfactory results. However, for calculating deflections it is necessary to include the effects of the root-triangle deformation.

Download The Calculation of Span Load Distributions on Swept-back Wings Book in PDF, ePub and Kindle
Span load distributions of swept-back wings have been calculated. The method used was to replace the wing with a bound vortex at the quarter-chord line and to calculate the downwash due to the system of bound and trailing vortices to conform at the three-quarter-chord line to the slope of the flat-plate wing surface. Results are given for constant-chord and 5:1 tapered plan forms, for swee-pback angles of 0, 30 and 45 degresss, and for aspect ratios of 3, 6, and 9. Some comments on the stalling of swept-back wings are included.

Download A Finite Step Method for the Calculation of Span Loadings of Unusual Plan Forms Book in PDF, ePub and Kindle
The applicability of a well-known finite-step method to the calculation of subsonic spanwise load distribution, lift-curve slope, lateral center of pressure, and aerodynamic center of unusual plan forms has been investigated. Computing forms are presented to simplify calculation of span loadings for conventional swept, M plan-form, and W plan-form wings. Tables of the downwash in the plane of a yawed vortex are presented.

Download An Application of Falkner's Surface-loading Method to Predictions of Hinge-moment Parameters for Swept-back Wings Book in PDF, ePub and Kindle
Application of the Falkner lifting-surface-theory method to the prediction of hinge-moment and, incidentally, lift parameters for swept-back plan forms has been made in an attempt to develop an analogue to the existing lifting-surface-theory procedure for prediction of these parameters on unswept plan forms. For the two specific swept-back plan forms investigated the hinge-moment predictions based on the Falkner method were not in good agreement with experimental values. The discrepancies between the predicted and the experimental results probably are due to the effects of fluid viscosity which were not included in the Falkner method as applied herein.
