Summary:

A simplified type of all-metal wing construction of 18-8, spot-welded except for the skin attachment, was tested by means of hydrostatic loading, the wing being proportioned to permit close representation of typical conditions by means of the waterhead.

The general principle of design was to apply the skin on the wing under controlled initial tension and to utilize a finite internal pressure in flight. The initial tensioning was found to be an essential factor and the internal pressure in flight an important factor, although neither was critical with respect to small variations.

The results showed the possibility of eliminating almost all of the stiffners from a stressed-skin wing, the possible reduction of weight in a lightly loaded wing and of substantial cost in the construction of any all-metal wing. Further experiments are suggested on the magnitude and the effect of slight surface irregularities and on the contribution of the complete wing tip. A discussion of these suggested experiments is not included in the present paper.

With certain recommended improvements, the test method described is believed to be a valuable one for research on any new type of wing construction, particularly in cases where the covering, regardless of material or arrangement, is questionable.
