Summary. Three planforms, rectangular, delta and symmetrical tapered, have been selected for combined theoretical and experimental aerodynamic research. Numerous linearized theoretical methods have been applied to each ...

If ad hoc wind-tunnel work on controls is to be of value it is essential that the same precautions should be taken as are necessary for fundamental research. For the model there must be careful selection of material and ...

This note explains an improved numerical method of evaluating the contributions to the downwash at moderate or large spanwise distances from a vortex lattice. By allowing freedom of choice of ihe chordwise positions of the ...

An approximate theoretical formula for the distribution of aerodynamic load over arbitrary thick wings in incompressible flow is developed by combining three-dimensional results from thin-wing theory with twodimensional ...

There is a great need for more accurate data on the aerodynamic derivatives of swept-back wings in order to solve problems of stability, control and flutter. As one step in the search for these data the estimation of the ...

Leading-edge separation from fairly thin wings of moderate or low aspect ratio gives rise to aerodynamic loading and forces that are non-linear with incidence. It is important to be able to estimate these effects theoretically ...
