Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.In addition, if below in described each embodiment of the present invention involved technical characteristic do not form conflict each other and just can mutually combine.
As shown in Figure 1, be the structural representation of the parafoil according to the present invention's realization, in above-mentioned figure, illustrate the integral structure schematic diagram of parafoil, and the integral structure of its leading edge opening portion and parafoil is shown.
In Fig. 2, the cover 4 of the whole length of its air chamber open ribs 1 of parcel is respectively made in the front portion of all ribs 1 in parafoil leading edge opening portion along outline, and the nylon wire 5 penetrated in cover 4 for supporting, the diameter of this nylon wire is generally 4 ~ 6mm, closes the two ends of cover 4 simultaneously.The diameter of nylon wire is arranged on this scope, make the diameter of nylon wire can not be too little, also not too large, make to support bending when reclaiming, enough bearing forces can be provided again, and increase too many weight load can not to taking off of parafoil, and within this number range, produce large impact can not to the integrally-built aerodynamic properties of parafoil.
Further, in cover 4, penetrate nylon wire 5, close the two ends of cover 4, thus nylon wire 5 can not be stretched out in the process reclaimed and fly from cover 4, impact flight.Meanwhile, in order to not allow cover cause too many obstruction to parafoil in flight course, the diameter of cover 4 should, slightly larger than the diameter of nylon wire, make cover 4 can not cause large obstruction to flight.
Further, larger to the effect of cover 4 because wind-force is comparatively large in order to reach nylon wire 5 in-flight better, nylon wire is caused to be gone here and there out from cover 4, the two ends that can contact with nylon wire about 5 at cover 4 arrange two rigid disks, and the material of cover 4 is set to the version that nylon wire not easily passes, make the rigid face at upper and lower two ends and nylon silk braid form cylindric structure, thus strengthen its flight and the stability in reclaiming.
Further, if the span of leading edge open plenum is larger, the nylon wire that rib 1 is arranged only is relied on likely to make leading edge not be shaped completely, in order to more effectively prop up leading edge air chamber, and top airfoil 2 in each of front in edge air chamber and lower aerofoil 3 from air chamber leading edge opening part backward extension seam be shaped with some covers 4, in cover 4, also nylon wire is set, thus supporting role is more strongly realized to air chamber, simultaneously in order to save material, and need the grade strength according to wind-force, the shape size of air chamber opening arranges the development length of cover 4, the length of this extension general is equal with the length of the rib of upper and lower both wings, if need more smoothly wind-force to fill air chamber, then the length of this extension can be increased but not beneficial this length is arranged to aerofoil length equal, the structure of parafoil is caused to change like this, and increase the resistance and difficulty that reclaim and again launch.
In order to not add to the difficulties to removal process, the setting of rib had better not be carried out at the two ends up and down of aerofoil, to such an extent as to reclaim process in, if the set-up mode of encapsulation and nylon wire has also been carried out in the aerofoil upper end of leading edge air chamber opening, then can cause reclaim process in difficulty can be very large.
Further, in order to reduce the cost of setting, the rib that there is no need edge air chamber opening in each of front all carries out the setting of nylon wire, can arrange by some ribs of interval, the distance at interval is not too big, is good with 2-4 leading edge air chamber opening.
Further, in order to reduce the resistance owing to producing when wind is filled into leading edge open plenum, arranging of this cover can in one end of the close parafoil of rib, wind energy can be made like this to enter leading edge air chamber enough smoothly, be unlikely to due to cover and nylon wire effect and the front end of leading edge open plenum generation resistance.
Simultaneously, the material of the cover made can be the material of flexible cloth matter, or the material that the higher some fibre class of intensity is made, such as: thin renforce, and the nylon wire be arranged at for supporting in cover, be not strictly only defined as nylon wire yet, and the thread structure can made for the material of some flexibilities, such as: glass fiber or carbon fiber wire, the effect played and support leading edge opening can be positioned in cover.
According to the parafoil structure that the present invention realizes, utilize auxiliary flexible material to instead of flexible plastic sheet of the prior art, and the preferred modes such as the position of above-mentioned auxiliary flexible material are arranged, thus reach the result of better flight experience effect.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
