Technical Field

The application relates to the technical field of aircraft structure design, in particular to a cross-medium variant wing watertight device and a cross-medium variant aircraft.

Background

The development of the telescopic wing technology worldwide has started very early. In 1929, the GX-3 airplane designed by American airplane design Entechure, Gaster and Borrelia successfully flies for the first time, and the airplane integrates a plurality of new ideas in the aviation field at that time, such as a lifting body fuselage (namely a prototype of a BWB layout), a telescopic variable-area wing, a variable-camber wing, a full-span high-lift wing flap, a wing tip winglet, a wing tip aileron and the like, and obtains a concept patent of the telescopic wing which is probably the earliest in the world. In the next decades, the research on the telescopic wing technology in western countries has not been stopped, and the research results in various aspects continuously report the invention patents of a plurality of telescopic wing mechanisms and application concepts.

When the cross-medium aircraft enters water at a high speed, the wings are greatly impacted by the water surface to cause structural damage, and when the cross-medium aircraft sails underwater, the wings are not needed to provide large lift force, and the large-area wings bring unnecessary resistance and excessive lift force instead, so that the cross-medium aircraft can fly/sail in different media by changing the areas of the wings in different media through expansion and contraction. Patent publication No. CN111003145A (a variable unmanned aerial vehicle) discloses a telescopic morphing wing scheme, which can change the wing area by over-extension, but the morphing wing does not have water tightness and cannot be applied to a cross-medium aircraft.

The following describes in detail an implementation of a cross-medium morphing wing watertight device and a cross-medium morphing aircraft provided by an embodiment of the present invention with a specific implementation example.

As shown in fig. 2 and 3, the cross-media variant aircraft may include: the middle fuselage is fixedly arranged on the inner wings at two sides of the middle fuselage, and the outer wings are nested in the inner wings from the end parts of the inner wings; the inner wing is of a central wing type structure, penetrates through the fuselage, can accommodate the outer wing inside, and is provided with a watertight device of the cross-medium variant wing in the region where the inner wing and the outer wing on two sides are nested.

As shown in fig. 3, the structure and installation position of the watertight device for the cross-medium morphing wing are that inner wing end plates 1 for sealing are arranged on the end surfaces of the inner wings at two sides, inner side sealing rings 2 are arranged on the inner sides of the inner wing end plates 1, outer side sealing rings 3 are arranged on the outer sides of the inner wing end plates 1, and an opening in the inner wing end plates 1 can allow the outer wings to pass through; one end of the two ends of the outer wing, which are positioned in the inner wing, is provided with an inner end plate 4 of the outer wing for sealing, and the outer end of the outer wing is provided with an outer end plate 5 of the outer wing; the integrated wing beam 6 is arranged on the inner side of the inner wing, and particularly, the wing beam and the outer wing which are arranged on the inner side of the inner wing are nested on the corresponding nesting area of the inner wing, so that the integrated wing beam 6 not only bears the bearing function of a common wing beam, but also has the functions of a guide rail and a rack; the worm 7 is arranged on an output shaft of the motor 8, meshed with the rack on one side of the integrated wing beam 6 and driven by the motor 8. The motor 8 is arranged on the sliding block 9 and used for driving the outer wing to stretch; the sliding blocks 9 are fixedly connected with the wing spars of the outer wing and can move along guide rails on the integrated wing spars 6.

In this embodiment, the operation mode of the cross-medium morphing wing watertight device is as follows:

when the outer wing is driven by the motor 8 to extend to the maximum expansion position, the inner end plate 4 of the outer wing extrudes the inner sealing ring 2 on the inner side of the inner wing end plate 1 to play a watertight role, and the self-locking characteristic of a worm rack mechanism consisting of the worm 7 and the rack on the integrated wing beam 6 can ensure that the sealing structure is not loosened; when the outer wing is driven by the motor 8 to retract to the minimum deformation position, the outer end plate 5 of the outer wing extrudes the outer sealing ring 3 on the outer side of the inner wing end plate 1 to play a watertight role, and the self-locking characteristic of a worm rack mechanism consisting of the worm 7 and the rack on the integrated wing beam 6 can ensure that the sealing structure is not loosened.

Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
