Description

本発明は、翼付きの移動体に係り、より詳細には、翼付き移動体の主翼の構造に係る。   The present invention relates to a moving body with wings, and more particularly, to a structure of a main wing of a moving body with wings.

近年、地上では自動車と同様に車輪にて走行でき、且つ、空中では飛行機(固定翼機)と同様に翼にて飛行することのできる翼付き移動体(飛行可能モビリティ、フライング・カーとも称される。)として、種々の構造が提案されている。特に、そのような翼付き移動体の場合、その重量から見積もられる相応の主翼面積(例えば、10m程度)が必要となるので、そのような面積の主翼が地上での走行の妨げとならないように、地上走行状態で主翼をコンパクトに格納し或いは折り畳むことが一つの課題となっている。かくして、コンパクトに格納可能な主翼構造として、例えば、柔らかい素材から成る浮き袋の如き翼構造にして、翼の使用時には、空気を入れて空気圧力により膨らませて翼構造を伸長させ、収納時には袋の構造を密に折畳んで格納するインフレータ式の翼構造、硬い素材から形成された複数に分割された部分が入れ子式に連結された翼構造にして、収納時には先端部分から根元部分へ向かって順々に内側に収容されて短縮する構造を有するテレスコピック式の翼構造(特許文献1〜2)、或いは、硬い素材から形成された複数に分割された部分が互いにヒンジにより連結された翼構造にして、収納時には伸長していた複数の部分がそれぞれヒンジにて屈曲される折り曲げ式の翼構造(特許文献3〜4)などが検討されている。 In recent years, a winged mobile body (also called a flying vehicle or flying car) that can run on wheels like a car on the ground and can fly on a wing like an airplane (fixed wing aircraft) in the air. Various structures have been proposed. In particular, in the case of such a winged moving body, a corresponding main wing area (for example, about 10 m 2 ) estimated from its weight is required, so that the main wing of such an area does not interfere with traveling on the ground. In addition, it is a problem to store or fold the main wing in a ground running state in a compact manner. Thus, as a main wing structure that can be stored compactly, for example, a wing structure such as a floating bag made of a soft material is used, and when the wing is used, the wing structure is expanded by inflating it with air pressure, and when storing the bag structure Inflator type wing structure that folds and stores the wing structure, and a wing structure in which multiple divided parts made of hard material are connected in a nested manner, and in order from the tip part to the root part during storage The telescopic wing structure (Patent Documents 1 and 2) having a structure that is housed inside and shortened, or a wing structure in which a plurality of divided parts formed of a hard material are connected to each other by a hinge, A folding type wing structure (Patent Documents 3 to 4) in which a plurality of portions that have been extended at the time of storage are bent by hinges has been studied.

上記の如き種々の翼構造のうち、インフレータ式の翼構造の場合には、下記のような課題を有している。まず、高い翼面荷重を支えるために、ストラット、吊線などによる荷重の分散が図られるが、そうすると、抵抗が増加し、高速飛行が困難となり得る。また、コンパクトに自動的に収納できるようにするために、脱気や巻取りのための機構が必要となるところ、巻取りロール径が大きくなり、地面に接触してしまうなどの支障が生じ得る。更に、柔らかい素材で形成されるので、翼表面が鳥、雹、異物等の衝突で破れ、揚力喪失してしまうことを回避すべく、多胞化したり、前縁部鎧状ガードを用いたりした場合、或いは、翼型表面乱れによる揚力の減少と抵抗の増大を回避するために、中仕切りや面剛性ある表面材を用いた場合には、重量の増大に繋がってしまう。そして、エルロン、フラップなどの動翼を構成することを考えると、空気圧式のアクチュエータによる翼型変更が想定されるところ、その場合には、応答が遅いなどの問題が生じ得る。その他、インフレータ式の翼構造の場合、耐久性、耐光性、耐候性などの課題もあるので、実際に人が乗る実用的な翼付き移動体への適用は困難であると考えられる。   Among the various blade structures as described above, the inflator type blade structure has the following problems. First, in order to support a high wing surface load, the load is distributed by struts, suspension lines, and the like. However, this increases resistance and makes high-speed flight difficult. In addition, in order to automatically store in a compact manner, a mechanism for deaeration and winding is required. However, the diameter of the winding roll becomes large, and troubles such as contact with the ground may occur. . In addition, because it is made of a soft material, the wing surface was broken into multiple wings and a front edge armor guard was used to avoid losing lift due to the collision of birds, spiders, foreign objects, etc. In order to avoid a decrease in lift and an increase in resistance due to airfoil surface disturbance, the use of a partition or a surface material with surface rigidity leads to an increase in weight. Considering the construction of moving blades such as ailerons and flaps, it is assumed that the airfoil type is changed by a pneumatic actuator. In this case, problems such as slow response may occur. In addition, since the inflator type wing structure has problems such as durability, light resistance, and weather resistance, it is considered difficult to apply it to a practical winged moving body on which a person actually rides.

一方、テレスコピック式の翼構造は、次のような主として機械的な構造に関わる課題を有している。まず、翼付き移動体の主翼に於いては、揚力分布は、翼巾方向に於いて楕円分布のようになるところ、テレスコピック式の翼構造では、片持ち梁式の構造となるので、翼の根元部分に大きな曲げモーメントが作用することとなる。そうすると、かかる高い翼面荷重を支えるためには、例えば、翼構造内部にクレーン伸縮ジブ状スパーの如き構造を採用することが考えられるが、先端部分から根元部分へ向かって順々に内側へ収容されるテレスコピック式の幾何学的な構成に於いて、翼型を形成する外側の表面部分(スキン部)と翼面荷重を支える内側の主桁(スパー)とを連結できるようにする構造は、複雑な機構を必要とし、その結果、重量の増大、機構の複雑化を引き起こし得ることとなる。また、エルロン機能やフラップ機能等の動翼機能を考える場合、そういった機能を持たせることができる部分は、翼の最外部分又は先端部分に限られることとなり、十分な機能が得られるかどうかが問題となる。更に、テレスコピック式構造に於ける各部分の連結部に於ける段差による渦の発生及びこれによる揚力の減少、抵抗の増大を回避し、或いは、連結部に於ける引掛りなど動作不良を回避するために、テレスコピック式構造の連結部の設計及び製作にも労力、時間、費用を要することとなる。   On the other hand, the telescopic blade structure has the following problems mainly related to the mechanical structure. First, in the main wing of a winged moving body, the lift distribution is an elliptical distribution in the wing span direction. In the telescopic wing structure, a cantilever structure is used. A large bending moment acts on the root portion. Then, in order to support such a high blade load, for example, it is conceivable to adopt a structure such as a crane telescopic jib spar inside the blade structure, but it is accommodated inward from the tip part to the root part in order. In the telescopic geometric configuration, the structure that allows the outer surface part (skin part) forming the airfoil to be connected to the inner main beam (spar) that supports the blade load is as follows. A complicated mechanism is required, and as a result, the weight can be increased and the mechanism can be complicated. In addition, when considering blade functions such as the aileron function and flap function, the part that can have such a function is limited to the outermost part or tip part of the blade, and whether or not sufficient functions can be obtained. It becomes a problem. Furthermore, the generation of vortices due to a step in the connecting portion of each part in the telescopic structure and the reduction in lift and the increase in resistance due to this, or the malfunction such as the catch in the connecting portion is avoided. Therefore, labor, time, and cost are also required for designing and manufacturing the connecting portion of the telescopic structure.

更に、折り曲げ式の翼構造の場合には、テレスコピック式の翼構造の場合と同様に片持ち梁式の構造となるところ、高い翼面荷重を支えられるようにヒンジ部分に剛性を持たせると、機構が複雑となったり、重量の増大を引き起こし得る。また、折り曲げ式構造に於ける各部分の連結部に於いては、テレスコピック式構造の場合と同様の問題が生じ得る。   Furthermore, in the case of a folding type wing structure, it becomes a cantilever type structure as in the case of a telescopic type wing structure, and if the hinge part is rigid so as to support a high blade surface load, The mechanism may be complicated or increase in weight. Further, in the connecting portion of each part in the folding structure, the same problem as in the telescopic structure can occur.

かくして、翼付き移動体の主翼構造に関しては、上記の列記した如き問題が軽減される新規な構造が利用できると有利であろう。従って、本発明の一つの課題は、翼付き移動体に於ける格納可能な主翼構造であって、従前のインフレータ式、テレスコピック式或いは折り曲げ式とは異なる構造であり、それら従前の構造に比して、揚力に対する強度がより高く、且つ、できるだけ小さく収納することのできる構造を提供することである。   Thus, with regard to the main wing structure of a winged mobile body, it would be advantageous if a new structure could be used that would alleviate the problems listed above. Therefore, one object of the present invention is a retractable main wing structure in a winged mobile body, which is a structure different from the conventional inflator type, telescopic type or folding type, compared to the conventional structure. Thus, it is to provide a structure having higher strength against lift and capable of being stored as small as possible.

本発明によれば、上記の課題は、翼付き移動体であって、胴体と、該胴体の左右に設けられる一対の主翼部にして、前記胴体の左右側面の各々から外方へ延伸する内翼部と、前記主翼部の格納状態に於いては前記内翼部の外表面に覆うように該内翼部に外嵌され、前記主翼部の展開状態に於いては前記内翼部の先端部から外方へ延伸する鞘状の外翼部とを含む主翼部とを有する移動体によって達成される。   According to the present invention, the above-mentioned problem is a winged moving body, and is an inner body that extends outwardly from each of the left and right side surfaces of the fuselage with a fuselage and a pair of main wings provided on the left and right sides of the fuselage. In the retracted state of the wing part and the main wing part, it is fitted on the inner wing part so as to cover the outer surface of the inner wing part, and in the deployed state of the main wing part, the tip of the inner wing part And a main wing part including a sheath-like outer wing part extending outward from the part.

上記の本発明の構成に於いては、端的に述べれば、地上では車輪にて走行でき、空中では翼にて飛行することのできる「翼付き移動体」に於いて、移動体の胴体(車体又は機体)の両側に取り付けられた主翼が、内翼部と外翼部とから構成される。ここで、内翼部は、胴体から左右側面にて外方へ延在し、外翼部は、内翼部上に外嵌される鞘状構造に形成される。内翼部と外翼部とは、この分野で利用される任意の硬質の材料にて形成されてよい。そして、外翼部は、主翼部の展開状態、即ち、移動体の空中飛行のために、主翼が胴体から完全に延伸した状態に於いては、内翼部の先端部から更に外方へ延在し、主翼部の格納状態、即ち、地上走行のため、主翼が収縮される状態に於いては、内翼部を外側から覆うように内翼部上に嵌合されるよう構成される。かかる構成によれば、まず、主翼部の展開時に内翼部よりも先に延在する部分、即ち、外翼部が主翼部の格納時に内翼部の内側に入れ子式に収容されるといったことがないので、テレスコピック式の構造とは異なり、内翼部に於いて、外側にて翼型を形成する外皮又はスキン部と、内側にて翼面荷重を支えるべく延在する主桁とを連結することが容易となる。これにより、片持ち梁式の主翼構造に於いて、翼の根元に作用する大きな曲げモーメントに耐え得る構造を複雑化することなく形成可能となることが期待される。なお、外翼部もその部分にて作用し得る曲げモーメントに耐え得る強度に形成される。また、内翼部の内側には、入れ子式に収容される部品がないことから、エルロン、フラップ或いはフラッペロン等の動翼構造を比較的簡単な構成にて装備することも可能となるので、内翼部に、かかる動翼構造が設けられてよい。   In the above-described configuration of the present invention, to put it briefly, in the “moving body with wings” that can travel on wheels on the ground and can fly on the wings in the air, Or a main wing attached to both sides of the airframe) includes an inner wing portion and an outer wing portion. Here, the inner wing portion extends outward from the body on the left and right side surfaces, and the outer wing portion is formed in a sheath-like structure that is fitted onto the inner wing portion. The inner wing portion and the outer wing portion may be formed of any hard material used in this field. The outer wing extends further outward from the tip of the inner wing when the main wing is fully extended from the fuselage because the main wing is deployed, i.e., for the flying of the moving body. In the retracted state of the main wing part, that is, in the state where the main wing is contracted for ground running, the inner wing part is configured to be fitted on the inner wing part so as to cover from the outside. According to such a configuration, first, a portion extending before the inner wing portion when the main wing portion is expanded, that is, the outer wing portion is accommodated in a nested manner inside the inner wing portion when the main wing portion is retracted. Unlike the telescopic structure, the inner wing part connects the outer skin or skin part that forms the airfoil on the outside and the main girder that extends to support the blade load on the inside. Easy to do. As a result, it is expected that a cantilever type main wing structure can be formed without complicating a structure capable of withstanding a large bending moment acting on the root of the wing. The outer wing portion is also formed with a strength that can withstand a bending moment that can act on the outer wing portion. In addition, since there are no telescopic parts inside the inner wing, it is possible to equip a moving blade structure such as an aileron, flap or flaperon with a relatively simple structure. Such a moving blade structure may be provided on the wing portion.

実施の形態に於いて、内翼部と外翼部とは概ね同じ長さとなるように、即ち、それぞれの主翼の片翼巾のほぼ半分の長さとなるように形成されてよい。これにより、外翼部が内翼部上に完全に嵌合した状態では、内翼部の根元から外翼部の先端までの長さは、片翼巾のほぼ半分に短縮されることとなる。主翼部が格納状態から展開状態へ変位する際には、内翼部上に外嵌された鞘状の外翼部が翼巾外方向に内翼部上を摺動して延伸して内翼部の外端に外翼部の内端が固定されるようになっていてよい。内翼部上にて鞘状の外翼部を摺動させるための機構は、任意の形式にて達成されてよい。そのような機構としては、例えば、後の実施形態の欄にてより詳細に例示される如く、外翼部の長手方向に歯切りをした棒状のラックを取り付け、内翼部にそのラックに噛み合うピニオンを取り付け、外翼部が内翼部上を長手方向(翼巾方向)に伸縮駆動することを可能する構造が採用されてよい(内翼部にラックが設けられ、外翼部にピニオンが設けられてもよいことは理解されるべきであり、そのような場合も本発明の範囲に属する。)。また、主翼部の展開状態に於いて、内翼部の外端に外翼部の内端を固定するための機構、例えば、内翼部の外端に、外翼部の内端にてその内側から係止するロック機構など、が設けられていてよい。なお、本発明による主翼構造が適用される移動体に於いては、詳細には図示していないが、更に、主翼部を格納状態にして、移動体が地上走行する場合に、格納状態の主翼部が胴体の長手方向に沿って延在するように、内翼部の根元には、内翼部を枢動する機構が設けられてよい。これにより、移動体の幅が、実質的に胴体の幅まで収縮されることとなる。   In the embodiment, the inner wing portion and the outer wing portion may be formed to have substantially the same length, that is, to be approximately half the length of one wing width of each main wing. As a result, in a state where the outer wing portion is completely fitted on the inner wing portion, the length from the root of the inner wing portion to the tip of the outer wing portion is reduced to almost half of the width of one wing. . When the main wing part is displaced from the retracted state to the deployed state, the sheath-like outer wing part fitted on the inner wing part slides and extends on the inner wing part in the outer direction of the wing width, and extends the inner wing. The inner end of the outer wing portion may be fixed to the outer end of the portion. The mechanism for sliding the sheath-like outer wing on the inner wing may be achieved in any manner. As such a mechanism, for example, as illustrated in more detail in the column of the following embodiment, a rod-shaped rack cut in the longitudinal direction of the outer wing is attached, and the inner wing is engaged with the rack. A structure may be adopted in which a pinion is attached and the outer wing part can be extended and contracted in the longitudinal direction (wing width direction) on the inner wing part (a rack is provided on the inner wing part, and a pinion is provided on the outer wing part). It should be understood that such may be provided and such cases are within the scope of the present invention). Also, in the deployed state of the main wing part, a mechanism for fixing the inner end of the outer wing part to the outer end of the inner wing part, for example, at the outer end of the inner wing part at the inner end of the outer wing part. A lock mechanism or the like that is locked from the inside may be provided. Although not shown in detail in the moving body to which the main wing structure according to the present invention is applied, when the moving body travels on the ground with the main wing part in the retracted state, the main wing in the retracted state A mechanism for pivoting the inner wing portion may be provided at the base of the inner wing portion so that the portion extends along the longitudinal direction of the body. Thereby, the width | variety of a moving body will be shrunk | reduced to the width | variety of a trunk | drum substantially.

かくして、上記の本発明の如く主翼部に於いて外翼部が内翼部上にて伸縮可能に外嵌される構造に於いては、内翼部の内側にて翼面荷重を支えるべく翼巾方向に延在する主桁に対して直接に外側にて翼型を形成する外皮又はスキン部を連結することが容易となるので、主翼の翼巾方向が伸縮可能な構造であって尚且つ(相対的に)大きな曲げモーメントが作用する主翼の根元側(内翼部側)の強度を高めることが容易に可能となる。また、外翼部も内翼部も硬質な材料で製作されてよいので、インフレータ式の構造の場合の、鳥、雹、異物等の衝突で翼表面が破れるなどの種々の問題は解消されることとなる。更に、外翼部が内翼部上に外嵌される本発明の構造によれば、既に触れた如く、(テレスコピック式の構造のように)主翼の格納状態で外翼部が内翼部の内側に入り込む、といったことや、(折り曲げ式の構造のように)翼部分の継ぎ目に剛性の高いヒンジを装備する、といったことの必要がなく、内翼部の内側の空間の自由度が高いので、揚力の高い内翼部側に動翼機構を容易に(然程に複雑化することなく)構成することが可能となり、従って、十分な機能を果たし得る動翼の構成を達成できることが期待される。   Thus, in a structure in which the outer wing portion is externally fitted on the inner wing portion so that the outer wing portion can be expanded and contracted on the inner wing portion as in the present invention described above, the wing is required to support the blade surface load inside the inner wing portion. Since it becomes easy to connect the outer skin or skin part forming the airfoil directly to the outer side of the main girder extending in the width direction, the structure of the main wing can be expanded and contracted, and It is possible to easily increase the strength of the base side (inner wing part side) of the main wing on which a (relatively) large bending moment acts. In addition, since both the outer wing and inner wing may be made of a hard material, various problems such as the wing surface being broken by the collision of a bird, a shark, a foreign object, etc. in the case of an inflator type structure are solved. It will be. Furthermore, according to the structure of the present invention in which the outer wing is fitted on the inner wing, as already mentioned, the outer wing is in the retracted state of the main wing (as in the telescopic structure). There is no need to enter the inside or to equip the joint of the wing part with a rigid hinge (like a folding structure), and the freedom of the space inside the inner wing is high. Therefore, it is possible to easily configure the rotor blade mechanism on the inner wing portion side having high lift (without so much complexity), and therefore, it is expected that the configuration of the rotor blade capable of performing sufficient functions can be achieved.

翼付き移動体の構成の概略
図1(A)〜(C)を参照して、本発明による翼付き移動体1は、自動車等の車両と略同様に内部に乗員席(図示せず)を有する胴体2と、その前後左右の車輪3FR、3FL、3RR、3RLと有する。そして、翼付き移動体1が空中にて飛行する状態に於いては、図1(A)に示されている如く、胴体2の前後の車輪の間の側部から左右外方に主翼部4L、4Rが延在し、胴体2の後方には、尾翼8が延在し、尾翼8の略上方に推進用のプロペラ9が装備される。一方、翼付き移動体1が地上にて走行する状態に於いては、尾翼8とプロペラ9とは、適宜折り畳まれて胴体2の後方のトランク18内へ格納され、主翼部4L、4Rは、図1(B)に示されている如く、翼巾方向に短縮され、しかる後、図示されていないが、それぞれ根元部分(内翼部連結部10−図2参照)にて、翼巾方向が胴体2の前後方向に沿うように枢動されて胴体2の下側へ格納されることとなる(図1(C))。
Referring to FIGS. 1 (A) to 1 (C) of the configuration of a winged mobile body, a winged mobile body 1 according to the present invention has a passenger seat (not shown) in the interior in substantially the same manner as a vehicle such as an automobile. It has a fuselage 2 and front, rear, left and right wheels 3FR, 3FL, 3RR, 3RL. In the state in which the winged moving body 1 flies in the air, as shown in FIG. 1A, the main wing part 4L extends laterally outward from the side part between the front and rear wheels of the fuselage 2. 4R extends, a tail 8 extends behind the fuselage 2, and a propeller 9 for propulsion is provided substantially above the tail 8. On the other hand, in a state where the winged mobile body 1 travels on the ground, the tail 8 and the propeller 9 are appropriately folded and stored in the trunk 18 behind the fuselage 2, and the main wings 4L and 4R are As shown in FIG. 1 (B), the blade width direction is shortened. Thereafter, although not shown in the drawing, the blade width direction is changed at the root portion (inner blade portion connecting portion 10-see FIG. 2). It is pivoted along the front-rear direction of the body 2 and stored below the body 2 (FIG. 1C).

主翼部の構成
上記の移動体1の構成に於いて、主翼部4L、4Rは、より詳細には、図1(A)に示されている如く、胴体2の側部に取り付けられた内翼部5L、5Rと、その内翼部の翼巾方向外端から更に外方へ延在する外翼部6L、6Rとから構成される。かかる内翼部5L、5Rと、外翼部6L、6Rとは、略同じ長さ、即ち、片翼巾のほぼ半分の長さをそれぞれ有するよう形成されてよく、更に、外翼部6L、6Rは、矢印aに示されている方向に摺動して内翼部5L、5R上へ外嵌可能な鞘状構造に形成される。従って、主翼部4L、4Rを格納するべく、図1(B)に示されている如く、主翼部4L、4Rをその翼巾方向に短縮する際には、外翼部6L、6Rは、内翼部5L、5R上を覆うように内翼部5L、5R上に嵌合され、逆に、空中飛行のために、主翼部4L、4Rを格納状態から展開状態にするには、図1(B)の状態から、外翼部6L、6Rが内翼部5L、5R上を摺動して、図1(A)に示されている如く、外翼部6L、6Rの翼巾方向内端部分が内翼部5L、5Rの翼巾方向外端部分に固定され、飛行可能な主翼部を形成することとなる。
Configuration of Main Wing In the configuration of the moving body 1 described above, the main wing 4L, 4R is more specifically the inner wing attached to the side of the fuselage 2 as shown in FIG. It is comprised from the outer wing | blade part 6L, 6R extended further outward from the wing-width direction outer end of the inner wing | blade part. The inner wing portions 5L and 5R and the outer wing portions 6L and 6R may be formed to have substantially the same length, that is, approximately half the width of one wing width. 6R is formed in a sheath-like structure that is slidable in the direction indicated by arrow a and can be fitted onto the inner wing portions 5L and 5R. Therefore, when the main wing parts 4L, 4R are shortened in the span direction as shown in FIG. 1B in order to store the main wing parts 4L, 4R, the outer wing parts 6L, 6R To fit the main wing parts 4L, 4R from the retracted state to the deployed state for air flight, the main wing parts 4L, 4R are fitted on the inner wing parts 5L, 5R so as to cover the wing parts 5L, 5R. From the state of B), the outer wings 6L and 6R slide on the inner wings 5L and 5R, and as shown in FIG. 1A, the inner ends in the wing width direction of the outer wings 6L and 6R. The portion is fixed to the outer end portion in the wing width direction of the inner wing portions 5L and 5R, and a flying main wing portion is formed.

上記の如き主翼部4L、4Rの構造によれば、まず、外翼部6L、6Rは、内翼部5L、5Rの内側ではなく、外側にて摺動することとなるので、内翼部5L、5Rの内側には、空間的に比較的余裕があり、従って、内翼部5L、5Rに於いては、エルロン、フラップ或いはフラッペロン等の、図1(A)中の矢印bにて示された方向に枢動する動翼機構7L、7Rを比較的容易に装備することが可能である。また、外翼部6L、6Rが内翼部5L、5Rの外側を摺動する構造によれば、図2又は図3に示されている如く、内翼部5L、5Rの内部に於いては、内翼部5L、5Rの表面外皮11に対して直接に接着した剛固な主桁12が延在するよう構成することが可能であり、かかる主桁12は、主翼全体の曲げモーメントに耐えることができ、且つ、主翼部を胴体下部へ収納するための根元部のヒンジ(図示せず)に作用する荷重に耐えられるものにすることが可能である。   According to the structure of the main wing parts 4L, 4R as described above, first, the outer wing parts 6L, 6R slide on the outside rather than the inside of the inner wing parts 5L, 5R. 5R has a relatively large space. Therefore, the inner wings 5L and 5R are indicated by an arrow b in FIG. 1A such as an aileron, a flap or a flaperon. It is possible to equip relatively easily with the moving blade mechanisms 7L and 7R that pivot in different directions. Further, according to the structure in which the outer wing portions 6L, 6R slide outside the inner wing portions 5L, 5R, as shown in FIG. 2 or 3, the inside of the inner wing portions 5L, 5R The rigid main girder 12 bonded directly to the surface skin 11 of the inner wing portions 5L and 5R can be extended so that the main girder 12 can withstand the bending moment of the entire main wing. It is possible to withstand the load acting on the hinge (not shown) of the root portion for accommodating the main wing portion in the lower part of the fuselage.

主翼部4L、4Rを展開及び格納するために、内翼部5L、5R上にて鞘状構造の外翼部6L、6Rを摺動するための機構(外翼伸縮機構)13及び内翼部5L、5Rに対して外翼部6L、6Rを固定するための機構(外翼固定機構)14は、任意の機構にて達成されてよい。   A mechanism (outer wing expansion / contraction mechanism) 13 and an inner wing portion for sliding the outer wing portions 6L and 6R having a sheath structure on the inner wing portions 5L and 5R in order to deploy and store the main wing portions 4L and 4R. The mechanism (outer wing fixing mechanism) 14 for fixing the outer wing portions 6L and 6R to 5L and 5R may be achieved by an arbitrary mechanism.

外翼伸縮機構13の一つの例は、図2及び図3に示されている如く、ラック・アンド・ピニオン機構により達成されてよい。具体的には、例えば、歯型を切ってある棒状の外翼伸縮用ラック13rを外翼部6L、6Rの長手方向に延在するよう取り付け、内翼部5L、5Rの最外端5Le(図示せず)、5Reにラック13rに噛み合う外翼伸縮用ピニオン13pを取り付けられる。そして、外翼伸縮用駆動モータ13mによってピニオン13pを回転することにより、ラック13rが図3中の矢印aの方向に駆動され、これと伴に外翼部6L、6Rが長手方向(翼巾方向)に伸縮するようになっていてよい。なお、図示していないが、内翼部5L、5R側にラック13rが備えられ、外翼部6L、6R側にピニオン13pとその駆動用モータ13mが設けられる構成であってもよく、そのような場合も本発明の範囲に属することは理解されるべきである。   One example of the outer wing telescopic mechanism 13 may be achieved by a rack and pinion mechanism as shown in FIGS. Specifically, for example, a rod-shaped outer wing expansion / contraction rack 13r having a tooth shape is attached so as to extend in the longitudinal direction of the outer wing portions 6L and 6R, and the outermost ends 5Le ( An outer wing expansion / contraction pinion 13p meshing with the rack 13r is attached to 5Re. Then, by rotating the pinion 13p by the outer wing expansion / contraction drive motor 13m, the rack 13r is driven in the direction of the arrow a in FIG. 3, and the outer wing portions 6L and 6R are moved in the longitudinal direction (wing width direction). ). Although not shown in the figure, the rack 13r may be provided on the inner wing portions 5L and 5R, and the pinion 13p and the driving motor 13m may be provided on the outer wing portions 6L and 6R. In any case, it should be understood that it falls within the scope of the present invention.

外翼固定機構14の一つの例は、図2及び図3に示されている如く、リンク及びロック機構により達成されてよい。具体的には、図3に詳細に描かれている如く、内翼部の最外端5Reにて、外翼6Rの外皮に対して係止される外翼固定用ロック15と外翼固定用ロック駆動装置16とが外翼固定用リンク17によって連結された構造が設けられる。そして、外翼固定用ロック駆動装置16が外翼固定用リンク17を介して、外翼固定用ロック15をピボット15c周りにて矢印x周りに回動すると、ロック爪15aが外翼内端の外皮に穿たれた孔部に係合し、これにより、外翼部6L、6Rの内端がそれぞれ内翼部5L、5Rの外端に固定され、かくして、外翼の揚力などによる荷重が内翼部へ伝達されることとなる。   One example of the outer wing securing mechanism 14 may be achieved by a link and locking mechanism as shown in FIGS. Specifically, as illustrated in detail in FIG. 3, an outer wing fixing lock 15 and an outer wing fixing lock which are locked to the outer skin of the outer wing 6R at the outermost end 5Re of the inner wing portion. A structure in which the lock driving device 16 is connected to the outer blade fixing link 17 is provided. Then, when the outer wing fixing lock driving device 16 rotates the outer wing fixing lock 15 around the pivot 15c around the arrow x via the outer wing fixing link 17, the lock claw 15a is moved to the inner end of the outer wing. Engaging with the hole formed in the outer skin, the inner ends of the outer wing portions 6L and 6R are fixed to the outer ends of the inner wing portions 5L and 5R, respectively. It will be transmitted to the wing.

上記の主翼部の構成に於いて、内翼部及び外翼部は硬質の材料から製作されてよい。例えば、外翼は、アルミ合金やCFRPなどの複合材の単板或いはハニカムや発泡樹脂などのコア(芯)材のサンドイッチ複合板により内翼を包むような鞘状の構造に作られてよい。また、外翼部の内側及び/又は内翼部の外側には、内翼外面と外翼内面との間の滑りを良くするためのポリテトラフルオロエチレンなどの潤滑性材料が貼り付けられていてよい。   In the configuration of the main wing part, the inner wing part and the outer wing part may be made of a hard material. For example, the outer wing may be made into a sheath-like structure that wraps the inner wing with a single plate of a composite material such as an aluminum alloy or CFRP or a sandwich composite plate of a core material such as a honeycomb or foamed resin. Also, a lubricating material such as polytetrafluoroethylene is attached to the inside of the outer wing and / or the outside of the inner wing to improve the slip between the outer surface of the inner wing and the inner surface of the outer wing. Good.

かくして、上記の実施形態の構成によれば、主翼部4L、4Rに於いて、鞘状の外翼部6L、6Rが内翼部5L、5R上にそれぞれ外嵌されて翼巾方向に伸縮されるようになっていることから、地上走行時には、主翼の翼巾方向の長さをコンパクトに短縮可能であると伴に(内翼部5L、5Rと、外翼部6L、6Rとは、略同じ長さに形成することができるので、主翼の格納時には、主翼の長さを、飛行時の半分の長さに短縮できることとなる。)、翼型を形成する外皮11に直接に接着した状態で翼面荷重を支えるべく翼巾方向に延在する主桁12を内翼部5L、5Rの内側にて配置することが容易となり、移動体の空中飛行時に於いて、大きな曲げモーメントが作用する内翼部の根元側の強度を容易に高めることができるようになる。また、既に述べた如く、内翼部の内側の空間の自由度が高いので、揚力の高い内翼部側に動翼機構を構成することが可能となり、従って、十分な機能を果たし得る動翼の構成を達成できることが期待される。   Thus, according to the configuration of the above-described embodiment, in the main wing parts 4L and 4R, the sheath-like outer wing parts 6L and 6R are respectively fitted on the inner wing parts 5L and 5R and expanded and contracted in the wing span direction. Therefore, when traveling on the ground, the length of the main wing in the wing width direction can be reduced in a compact manner (the inner wing portions 5L and 5R and the outer wing portions 6L and 6R are substantially Since they can be formed to have the same length, when the main wing is retracted, the length of the main wing can be shortened to half the length during flight.) Directly adhered to the outer skin 11 forming the airfoil Therefore, it becomes easy to dispose the main girder 12 extending in the span direction in order to support the blade load on the inner side of the inner wing portions 5L and 5R, and a large bending moment acts when the moving body is flying in the air. The strength on the base side of the inner wing portion can be easily increased. Further, as described above, since the degree of freedom of the space inside the inner wing part is high, it is possible to configure the moving blade mechanism on the inner wing part side having high lift, and therefore the moving blade capable of performing a sufficient function. It is expected that this configuration can be achieved.

以上の説明は、本発明の実施の形態に関連してなされているが、当業者にとつて多くの修正及び変更が容易に可能であり、本発明は、上記に例示された実施形態のみに限定されるものではなく、本発明の概念から逸脱することなく種々の装置に適用されることは明らかであろう。   Although the above description has been made in relation to the embodiment of the present invention, many modifications and changes can be easily made by those skilled in the art, and the present invention is limited to the embodiment exemplified above. It will be apparent that the invention is not limited and applies to various devices without departing from the inventive concept.
