um'rao STATES ALBERT RUURD KUIPERS, OF RIJ'SWIJ'K, NETHERLANDS.
WING FOR AEROPLANES.
Application filed February 16, 1924. Serial No. 693,317.
To all whom it may concern.
Be it known that I, ALBERT Room) KUIP- ERS, a subject of the Queen of the Netherlands, residing at Rijswijk, Zuid-Holland, the Netherlands, have invented certain new and useful Improvements in WVings for Aeroplanes, of which the following is a specification.
The present invention relates to a wing for aeroplanes and has for its object to increase the portative capacity of the wing. According to the invention the wing, which at the upper and lower side is provided with air cushioning means, comprises passages bringing into communication the interior of the air cushioning means with the atmosphere surrounding the wing and preferably these passages are so arranged that the interior of the air cushioning means under the wing is brought into communication with the atmosphere above the wing and the interior of the air cushioning means above the wing with the atmosphere in front of the wing.
In order that my invention will be more fully understood reference is directed to the accompanying drawing, illustrating it by way of example.
The wing proper 1, which can be one of ordinary structure, is provided on the upperside with an elastic membrane 2 and the intervening space 3 is filled with air under a higher pressure than the air of the surrounding atmosphere. On the underside an elastic membrane 4 is provided and the space 5 between these two is filled with air of lower pressure than that of the surrounding atmosphere.
. To be able to retain their form, the elastic membranes may be supported by metallic sprlings or springs of other elastic mater1a The different pressures in both these spaces 5 and 3 can be maintained mechanically, but they can also be maintained antomatically by connecting those spaces through tubes 67 and 8-9 with the air outside.
When the aeroplane is in action, pressure is created on the front edge and larefaction is obtained on the upperside of the wings. The tubes 67 and 8-9 guarantee that in the space 3 the same pressure will. reign as on the front edge and for the same reason there will be a rarefaction in the lower space 5.
By this arrangement the action of an aeroplane wing becomes somewhat similar to that of a birds wing. With an elastic upperside, above which there is a rarefaction, and with an elastic underside, underneath which there is pressure, the wing of the aeroplane is enabled to retain the energy of the pressure pulsations which are con tinually propagated upward from the surface of the earth.
There is no objection to divide the spaces into compartments, which compartments are then connected by separate tubes to the air outside; it is also preferable to have ridges in the material of the membranes, so as to diminish the lateral deviations of the air along the surface.
Having now particularly described and ascertained the nature of my said invention and the manner in which the same is to be performed, I declare that what I claim as new and desire to secure by Letters Patent is:
1. A wing for aeroplanes comprising a high air pressure receiving and cushioning means at the upper side of the wing and a low air pressure receiving and cushioning means at the under side of the wing, and passages for conducting air into the interior of the air receiving and cushioning means.
2. A wing for aeroplanes comprising air cushioning means at the upper as well as at the lower side of the wing, and passages, bringing into communication the atmosphere above the wing with the interior of the air cushioning means under the wing,
and bringing into communication the atmosphcre in front of the wing with the interior of the air cushioning means above the wing.
3. A wing for aeroplanes comprising air cushioning means at the upper as well as at the lower side of the wing, a covering of elastic material for said means, resilient means for keeping the covering in its desired form and passages, bringing into communication the interior of the air cushioning means with the atmosphere outside the wing.
4. A wing for aeroplanes comprising air cushioning means at the upper as well as at the lower side of the wing, partitions dielastic material for said means, ridges in said elastic material, and passages bringing into communication the interior of the air cushioning means with the atmosphere outside the Wing.
In testimony whereofIafiix my si ature.
ALBERT RUURD KUIP RS.
