A method for the calculation of three-dimensional turbulent boundary layers is given. It depends on the assumptions that the component of the velocity in the boundary layer parallel to the external streamlines follows a ...

A simple formula is derived for determining the onset of leading-edge buckling due to aerodynamic heating of wings which are either solid or thin-walled with a shear-resistant filling. The post-buckling behaviour is also ...

Camber and twist is applied to the problem of producing low-drag wings with no leading-edge pressure singularities, at design lift. The suction peaks near the leading edges of the wing are removed and the associated adverse ...

The response of a typical aircraft of the dive-bomber class to various disturbances has been calculated at four angles of dive covering tile range 0 to 90 deg and for four pairs of values of lv, nv. The most notable effect ...

This report describes a series of free-flight tests designed to investigate various methods of body shaping to achieve low drag at transonic and supersonic speeds. In all, ten configurations were flown; three had unwaisted ...

This paper collects together the flow patterns observed by an oil film (titanium oxide) technique over ten different Swept-back wings at high incidence and low Mach number in the Royal Aircraft Establishment 10-ft X 7-ft ...

A series of three thick uncambered slender wings and twelve flat-plate slender wings, all with sharp edges, have been tested in the 13 ft x 9 ft Low-Speed Wind Tunnel at the Royal Aircraft Establishment, Bedford. Pressure ...

A theoretical investigation of symmetric body freedom flutter of a rocket model is described. The results confirm that structural failures of models were caused by this type of flutter, and an extension of the investigation ...

An expression has been derived for the factor to he applied to ideal induced drag to allow for Wing-tail interference. This factor is primarily dependant on the wing-taillift and span ratios. It is of the order of 1.1 for ...

Measurements of local surface friction were made by Preston's method using a round pitot attached to the surface ('Preston .tube') and were compared with the values given by differentiation of overall measurements of surface ...
