  • Machine learning‐based wind classification by wing deformation in biomimetic flapping robots: Biomimetic flexible structures improve wind sensing Invited Reviewed International journal

    Flying animals such as insects and birds have strain receptors on their wings. The functions and information processing capabilities of these strain receptors, however, are largely unknown. Herein, the potential ability of wing strain sensors to detect wind direction in flapping flight is experimentally explored. Seven strain gauges are attached to the biomimetic wing shafts of flexible wings. The wings flap through an electric mechanism emulating hovering flight in a wind tunnel with gentle wind, and a convolutional neural network model for wind direction classification is developed. The results show that with only one strain gauge, accurate wind classification is achieved using segmented data of ≈1 flapping cycle. Even with segmented data of only 0.2 flapping cycles, wind classification can be achieved with all seven strain gauges. Moreover, the use of wing shafts improves the classification accuracy, especially with shorter segmented data. Additional flapping phase information does not substantially improve classification performance. These results suggest that hovering animals determine the wind direction via strain sensing, which is useful for flight control. The implementation of wing strain sensors in flapping‐wing aerial robots may improve flight control ability.

  • Three-dimensional shape of natural riblets in the white shark: relationship between the denticle morphology and swimming speed of sharks Reviewed International journal

    The ridges of the dermal denticles of migratory sharks have inspired riblets to reduce the frictional drag of a fluid. In particular, the dermal denticles of white sharks ( Carcharodon carcharias ) are characterized by a high middle ridge and low side ridges. The detailed morphology of their denticles and their variation along the body, however, have never been investigated. Moreover, the hydrodynamic function of high–low combinations of ridges is unknown. In this article, the ridge spacings and heights of the white shark denticles were three-dimensionally quantified using microfocus X-ray computed tomography. Then, the swimming speed at which the ridges would reduce drag was hydrodynamically calculated with a flat plate body model and previous riblet data. High ridges with a large spacing were found to effectively reduce drag at a migration speed of 2.3 m s −1 , while adjacent high and low ridges with a small spacing reduced drag at a burst hunting speed of 5.1 m s −1 . Moreover, the above hydrodynamic calculation method was also applied to the shortfin mako shark and an extinct giant shark (called megalodon) with known ridge spacings, resulting in the estimated hunting speeds of 10.5 m s −1 and 5.9 m s −1 , respectively.

    In this study, we introduce a new structure called the “connecting membrane” aiming to improve the performance of hummingbird-mimetic flapping wings. The “connecting membrane” is an extension of the wing membrane at the basal that connects the root shaft and the robot body, it elastically pulls the wing to stop the continuous feathering, thereby curbing feathering in the wing's root chord while promoting twist of the wing. This augmentation in total wing torsion improves lift generation. Tethered flapping experiments conducted at 24 Hz showed that the wing with the connecting membrane integrated achieved 24.2% higher power efficacy and 8.4% higher lift (116 mN) compared to the wing without a connecting membrane that flapped with a rigid limiter.

    Butterfly-type flapping flight was defined by a low flapping frequency, low wing loading and large wingspan. On the basis of the definition, we made a butterfly-type ornithopter (BTO). The BTO has no stabilizing device such as a tail fin, however, it flew stably when the position of the center of gravity was appropriate. Flights of the BTO were recorded with a high-speed video camera, and its longitudinal motion was measured. In the stable flight, angle of attack of the body α_<body> varied coincidentally with a flapping cycle. To reveal the effect of the change of α_<body> on aerodynamics, we visualized the air flows around the wing of the tethered BTO for several values of α_<body> When α_<body> is positive, leading edge vortex (LEV) was attached to the wing during downstroke, and it separated from the wing when α_<body> was too large. We also visualized the air flow around the free flying BTO. In this case, α_<body> was large in the beginning of downstroke, however, LEV was not separated from the wing during downstroke due to the rapid decrease of α_<body>. This result suggests that butterflies are designed to take advantage of passive change of α_<body>.

  • Alcids-like flapping wing for exploring the role of wing folding in underwater locomotion Reviewed International coauthorship International journal

    Alcids showcase excellent aerial–aquatic locomotion abilities benefitting from the morphing wing. In the aerial environment, alcids fully extend their wings, while underwater, they partly fold the wings. In this article, we mimicked the wing morphology of the alcids family to explore the hydrodynamic advantage of the folded configuration in the aquatic environment and four three-dimensional-printed wings including any combination of with feather or without feather, and extended or folded were created. The steady-state experiment reveals that the extended wings of alcids double the lift, counteracting gravity, while folding the wings halves the drag and reduces unnecessary lift, with configurations maintaining a similar lift-to-drag ratio. We investigated the alcid wing kinematics and designed an electronic wing mechanism with flapping and pitching motions to mimic the wing motion of the alcid. Quasi-steady estimation confirmed the presence of an active upstroke during diving in alcids. The experimental results validate the estimation, showing good agreement in force trends and average forward force. Additionally, the flapping wing experiment also demonstrates that pitch motion improves thrust generation, reduces lateral vibrations and increases mechanical efficiency. Under identical kinematics, extended models performed best, but alcids may prefer folded wings underwater for their highest thrust at the same Strouhal number and lower power needs.

    Hummingbird-inspired flexible wings were fabricated and tested with an electric flapping mechanism to explore the optimal design of the flexibility. The wing consisted of 3D-printed flexible radial shafts realizing spanwise torsion of the wing, an elastomeric membrane allowing the spanwise torsion by stretching, and a torsion-bar spring at the leading-edge base directly promoting the spanwise torsion. Measurement of lift and input power of the tethered flapping mechanism with different wing designs revealed that a favorable equilibrium between high lift and low power consumption can be achieved by the less-stiff torsion bar spring, stiff and tapered shafts, and the elastic membrane.

    Abstract

    Studies on the evolution of avian flight have failed to clarify why wing shape is weakly correlated with flight styles and phylogenetically constrained. Birds seem to have achieved their diverse flight styles owing to changes in the shapes of localized parts of the wing, despite a highly conserved wing outline. The alula, which stems from the first digit of the wing, is a part of the wing that might have enabled various flight styles to develop. To test this hypothesis, we measured alula length and width using museum specimens of 187 species from 21 orders of birds and used a phylogenetic comparative method to investigate the relationship between alula morphology and flight style, body mass, habitat and migratory distance. We found that: (1) phylogenetic signals were weak for the alula width and aspect ratio but moderate for length; (2) alula morphology exhibited an allometric relationship with body mass; and (3) fewer flapping birds had large alulae. Alula morphology might have evolved in response to changes in body mass and flight styles. Variations in the shape of localized wing parts, such as the alula, which modifies airflow around a wing, might be key to the evolution of the diverse flight styles of birds.

  • Hydrodynamics of gliding penguin flipper suggests the adjustment of sweepback with swimming speeds

    Hydrodynamic performance of a gliding penguin flipper (wing) considering the backward sweep was estimated with computational fluid dynamics (CFD) simulation. A flipper of a gentoo penguin (<italic>Pygoscelis papua</italic>) was 3D scanned, smoothed, and a numerical fluid mesh was generated. For accurate yet resource-saving computation, an embedded large-eddy simulation (ELES) methods was employed, where the flow near the flipper was solved with large-eddy simulation (LES) and flow far away from the flipper was solved with Reynolds-averaged Navier-Stokes (RANS). The relative flow speed was fixed at 2 m s-1, close to the typical foraging speed for the penguin species. The sweep angle was set to be 0°, 30°, and 60°, while the angle of attack was varied between -40° and 40°, both are within the realistic ranges in the wing kinematics measurement of penguins in an aquarium. It was revealed that a higher sweep angle reduces the lift slope, but the lift coefficient is unchanged at a high angle of attack. Drag coefficient was reduced across the angles of attack with increasing the sweep angles. The drag polars suggest the sweep angle may be adjusted with the change in swimming speed and anhedral (negative dihedral) angle to minimise drag while maintaining the vertical force balance to counteract the positive buoyancy. This will effectively expand the swimming envelope of the gliding penguin, similar to a flying counterpart such as swift.

    To achieve flight, an insect generates aerodynamic force by flapping its wings. However, this aerodynamic force acting on the wings has not been directly measured during free-flight. In this study, we fabricated an ornithopter modeled on a hawk moth, and attached a MEMS differential pressure sensor on its wing. Then, we measured differential pressure between upper and lower surfaces of the wing during free-flight. Reynolds number of the wing and wing load of the ornithopter were designed to be 4.2 × 103[–], and 7.5[N/m2], which were close to those of a hawk moth. The mass, wing length and flapping frequency were 6.8[g], 110[mm] and 13[Hz], respectively. The maximum differential pressures at the center of the wing were 39[Pa] and 18[Pa] during downstroke and upstroke, which were 5 and 2 times larger than the wing load. The differential pressure contributed vertical pressure of 38[Pa] during downstroke and horizontal pressure of 15[Pa] during upstroke. The time average of vertical differential pressure was 7.0[Pa], which was as large as the wing load of the ornithopter.

    A butterfly-type ornithopter (BTO) was developed to investigate flapping flight of butterflies. The BTO has the same values of wing length, flapping frequency and wing loading as butterflies. It flew forward when its center of gravity was appropriate. Its longitudinal motion was measured with a high-speed video camera. We found that the angle of attack of the body axis, α_&lt;body&gt;, varied coincidentally with flapping motion. Periodical change of α_&lt;body&gt; in the flight of a real butterfly was also observed. To reveal the effect of the change of abody on the aerodynamics, we visualized the flow around the BTO both in tethered flight and in free flight. In tethered flights, leading edge vortex was attached to the wing during downstroke when α_&lt;body&gt; was 20°, but it separated from the wing when α_&lt;body&gt; was 40°. However, in a free flight, leading edge vortex was attached to the wing in spite of the large value of α_&lt;body&gt;, 50°, in the beginning of downstroke.

    The vertical hovering behavior of the largehead hairtail (Trichiurus lepturus) represents an unusual example of extreme morphological and behavioral specialization among fishes. Unlike most hovering species that depend on continuous fin or body corrections, hairtails sustain a steep head-up posture with minimal muscular effort, relying largely on passive stability. By combining behavioral observations with hydrodynamic modeling, we examine how this species reconciles stability, maneuverability, and energy economy. The dorsoventrally streamlined body reduces drag and mitigates vortex-induced vibrations, while the longitudinal offset between the centers of mass and buoyancy produces a stabilizing hydrostatic torque. This arrangement enables energetically efficient station-keeping. Adjustable dorsal fin deployment further regulates yaw stability, allowing either passive turning or full directional stabilization depending on context.

    鳥は翼を羽ばたかせて空中を飛行できる。それだけではなく、水中を遊泳することもできる。飛行の極端な例が、鳥の中で最も小さく最も高速で羽ばたいて空中でピタリと静止できるハチドリのホバリングである。遊泳の極端な例は、水中遊泳に特化して飛行能力を失ったペンギンの羽ばたき推進である。筆者は、この両極端なハチドリとペンギンの両者を工学的な視点から研究してきた。どちらも鳥類で体の基本構成は同じだが、空気という軽い流体中を運動するのか水という重い流体中で運動するのかによって物理的な制約と要求が異なり、進化で獲得された羽と翼の機能も異なる。本講演では、ハチドリとペンギンという両極端な鳥の羽と翼に関する筆者のバイオミメティクス研究を4つ紹介する。
    1つ目の研究は、ハチドリのような羽ばたき飛行体のための人工柔軟翼である[1]。飛行する鳥の翼(よく)は多数の薄い風切羽で構成され、しなやかで軽量である。ハチドリの羽ばたきでは、翼は常に広げられて打ち下ろしと打ち上げの両方で揚力を発生し、そのために翼は大きくねじれ変形する。このねじれ変形は、手首関節の回転と風切羽同士のスライドで実現される。このような柔軟性を再構成した人工翼として、腕と手の骨格および風切羽の羽軸に相当するフレーム構造を3Dプリントで一体形成し、そのフレームで伸張性のあるエラストマーフィルムの翼面を支持するという構造を提案した。特に手首関節に相当する部分は、ねじれ板ばね状に形成して柔軟性を与えた。小さい構造を、軽量性を損なわずに高精度に製作するには、部品点数をできるだけ少なくして接合部と組立工程を簡略化するのがよい。結果として、本物の翼は多数の分離した部品(複数の骨と関節、多数の風切羽)で構成されるのに対して、人工翼は2つの部品の一体構造となった。
    2つ目の研究は、この人工翼を使った「感覚」の研究である[2]。鳥の腕と手、および昆虫の翅には、翼の変形に反応する機械受容器が点在している。翼の変形は空気力によって変わるので、翼の変形には周囲の風の情報が含まれていると考えられる。しかし鳥や昆虫が機械受容器でどんな情報を得ているのかは不明である。そこで、人工翼にひずみゲージを貼って、微風の中で羽ばたかせ、機械学習によってひずみデータから風向を分類できるのかを調べた。その結果、高精度で風向の分類に成功した。これは、柔軟に変形する羽ばたき翼が風を認識するセンサとしても機能することを意味する。
    3つ目の研究は、ペンギンの羽ばたき中の翼変形の研究である[3]。水の大きな流体力に適応して、ペンギンの翼は分厚く、腕と手の骨格がつまっており、頑丈である。浮力が自重を支えるので軽さは不要である。この頑丈な翼は、遊泳中は変形しない剛体と見なせるのか。多数の水中ビデオカメラによる詳細な3次元運動解析の結果、翼は打ち上げのときに腹側へしなやかに曲げ変形していた。この変形は、手首と手の関節で生じていると考えられる。流体力学計算の結果、この曲げ変形によって、推進に寄与しない背腹方向の力が低減して、推進効率が向上することが分かった。
    最後の研究は、ペンギンの胴体表面の羽の流体抵抗低減効果である[4]。体は細かい羽でびっしり覆われており、きれいな毛並みが頭から尾の向きに配向している。これまで体表の羽については、防水・保温効果が注目されてきた。本研究では体表の毛並みを、流体摩擦抵抗を低減する「リブレット」と見なして、ポリイミドフィルムの紫外線パルスレーザスキャン加工によってペンギン模倣リブレットフィルムを製作した。リブ断面形状は、羽枝の断面を模して台形とした。このフィルムを紡錘体に貼り、水流中で抵抗を計測したところ、未処理の平滑なフィルムを貼った場合に比べて、抵抗が約3 % 減少した。これはペンギン体表が流低抵抗の低減にも適応していることを示唆する。
    以上のように、鳥の羽と翼は飛行と遊泳に適応して、工学的に注目に値する機能を獲得している。そのバイオミメティクス研究は、新技術の開発だけでなく、鳥の羽と翼の進化と機能を力学の観点から理解するのにも役立つ。

    Previous studies on flapping-wing flight of animals and small unmanned aircraft at low Re (Reynolds number) revealed that a large lift can be generated at a large angle of attack due to the stable attachment of a leading-edge vortex (LEV) on the wing, that is so-called delayed stall. At high Re under water, however, vortex structures around the flapping wings are not fully understood yet. In this study, we perform high-fidelity simulations on a multi-GPU supercomputer to investigate LEV dynamics around the flapping wing of a penguin at high Re. Our computational model combines the cumulant lattice Boltzmann method (LBM) with the direct-forcing immersed boundary method (IBM), utilizing adaptive mesh refinement (AMR) method to optimize memory usage and ensure computational efficiency. The analysis focuses specifically on how the feathering angle influences vortex topology and the resulting hydrodynamic forces. Results indicate that even at high Re, a stable LEV forms at high angles of attack, inducing delayed stall. However, this vortex is observed to burst after the wing's midstroke. We demonstrate that variations in the feathering angle significantly alter flow separation, which in turn affects the drag forces acting on the wing. These findings provide a deeper understanding of high-Re flapping wing hydrodynamics, offering insights for the design of bio-inspired underwater and aerial vehicles.

    Event date: 2006

    Language:Japanese  

    We reported on the effect of the phase relationship between forewings and hindwings in the dragonfly flight. The dragonfly-type ornithopters (DTOs) were developed to investigate the flapping flight. The wing span of DTO is 100 mm long. Reynolds number is the same order as Dragonfly&#039;s Reynolds number (10^3). Flights of DTOs with various phase relationships were recorded with a high speed video camera, and their motions were analyzed. We also visualized air flow around the wings in a wind tunnel. We demonstrated that there are phase relationships for accelerating flight (45°), low speed flight (180°), high speed flight (270°,315°). This relationship between flight and phase almost matched that of dragonflies.

    A butterfly-type ornithopter (BTO) was developed to investigate flapping flight of butterflies. The BTO has the same values of wing length, flapping frequency and wing loading as butterflies. It flew forward when its center of gravity was appropriate. Its longitudinal motion was measured with a high-speed video camera. We found that the angle of attack of the body axis, α_&lt;body&gt;, varied coincidentally with flapping motion. Periodical change of α_&lt;body&gt; in the flight of a real butterfly was also observed. To reveal the effect of the change of abody on the aerodynamics, we visualized the flow around the BTO both in tethered flight and in free flight. In tethered flights, leading edge vortex was attached to the wing during downstroke when α_&lt;body&gt; was 20°, but it separated from the wing when α_&lt;body&gt; was 40°. However, in a free flight, leading edge vortex was attached to the wing in spite of the large value of α_&lt;body&gt;, 50°, in the beginning of downstroke.

    本年度は、昨年度の平板における研究成果に基づき、ペンギンの胴体の羽毛を模倣したリブレットフィルム製作と抗力計測の精度を向上させて、様々な条件で実験データを取得した。データの解析結果をまとめて、国内学会で1件発表し、国際論文を1報投稿した。国際論文は現在リバイズ中である。
    次に、リブレットフィルムを3次元物体に適用した。物体形状は断面が正12角形の紡錘体とし、3Dプリンタで製作した。紡錘体の側面輪郭曲線は、ペンギンの背中の輪郭に基づいて設計した。リブレットフィルムは正24角形紡錘体の展開図状に製作して、スプレー接着剤で貼付した。フィルムを貼付した紡錘体の抗力を回流水槽で計測した。平滑フィルムを貼付した場合と比較して抗力低減率を求めた。その結果、興味深いことに、平板の時よりも、抗力低減率は向上した。向上の理由が、ペンギンの羽毛に基づくリブレット形状に起因するのか、紡錘体まわりの表面流れに起因するのかは、まだ分かっていない。
    さらに、ペンギンの羽ばたきに伴うヒービング(背腹方向の振動)を再現するために、高速リニアアクチュエータを回流水槽に設置して、フィルムを貼付した紡錘体をヒービングさせながら抗力と揚力を2分力計で計測する装置を構成した。ヒービング振幅や速度は、当研究室で過去に行った実際のペンギン遊泳の運動解析結果に基づいて決定した。これまでに、ヒービング中においても、遊泳速度方向に対する抗力はリブレットフィルムによって固定時と同程度に低減するという結果が得られた。

    領域設定期間に明らかにすることは、羽ばたき飛行・遊泳生物のしなやかな飛行・遊泳を実現するE-kagenな流体構造連成メカニズム及び身体デザインである。そのために、次のA~Eの5項目に分類して研究を進めている:A.生物とロボットの「しなやかな運動」と「しなやかな変形」の定量的な計測;B.生物の翼・筋骨格構造の機械特性の計測;C.数値計算と機械モデル実験による流体構造連成メカニズムの解明;D.サブミリ構造製作技術を用いたソフト構造の実装;E.ソフト飛行・遊泳ロボットによるロバスト性・効率性・俊敏性の構成論的検証(当初計画に追加)。
    本年度は、ペンギンの羽ばたき前進遊泳の運動解析と流体力学解析の結果をまとめ、翼の打ち上げ中に翼が曲げ変形すること、および曲げ変形によって無駄な流体力が減少して推進効率が向上することを明らかにし、国際論文を発表した(項目A)。本成果をプレスリリースし、招待講演を多数行い、広く社会に周知した。また、ペンギンの羽ばたきを再現するロボットを回流水槽中で動かし、力計測とPIVによる流れ場計測と行い、剛体翼においてストローハル数が大きい低速遊泳において大迎角時に大きな前縁渦が発生して剥離が遅れ、大きな推力が発生することが分かった(項目C)。翼膜を支持する羽軸をポリイミドフィルムの積層によって製作してタフなハチドリ模倣翼を実現し、電動羽ばたき機構で羽ばたかせてPIVによる流れ場計測と力計測を行い、羽軸本数と変形および効率の関係を明らかにした(項目C, D, E)。さらに、ペンギンの胴体の羽毛が形成する微小列状突起構造を紫外線レーザ加工でポリイミドフィルムに形成して、回流水槽での力計測実験によって、流体摩擦抵抗が低減することを明らかにし、その効果は流速方向が列状突起に平行でなくても維持されることを明らかにした(項目D, E)。

    鳥の翼では柔軟かつ伸縮可能な翼面が羽根の微小な毛状構造の曲げ変形によって実現している。本研究では、柔軟かつ伸縮可能なフィルムの構造として、異方的に配向した微小なシワよって伸縮性と曲げ剛性を増加するシワフィルムを提案した。今年度は、市販の有限要素法ソフトウェア(ANSYS R15.0)を用いて、シワの波長と振幅が引張剛性に与える影響を調べた。その結果、振幅が増加すると引張剛性は指数関数的に減少することが分かった。また、曲げ剛性を断面2次モーメントから解析的に評価し、曲げ剛性は振幅・膜厚比の 2 乗に比例して増加することが分かった。たとえば波長 120 マイクロメートル、振幅 20 マイクロメートル、膜厚 5 マイクロメートル のシワフィルムの場合、引張剛性はシワが無い場合の 0.018 倍、曲げ剛性は 97 倍となる。このシワフィルムを手のひらサイズの小型羽ばたき飛行機の翼面フィルムに応用した。1 方向に配向させたシワフィルを用いて翼長 60 mm、最大翼弦長 30 mmの楕円翼を製作し、1 自由度の羽ばたき機構に取り付けて 24 Hz から 28 Hz で羽ばたかせ、翼面変形と平均揚力を計測した。翼のサイズと羽ばたき周波数はハチドリを規範として決定した。実験の結果、シワが無い場合と翼前縁に平行に配向させた場合は、翼面フィルムの後縁部が不規則に大きく振動するフラッターが見られた。一方、シワを前縁に垂直に配向させると翼後縁のフラッターは抑制され、翼面全体が前縁まわりにねじれて適切な迎え角を取った。また平均揚力は、シワなしと平行シワよりも 2 倍以上の大きさとなった。これによりシワによるフィルム剛性制御が羽ばたき翼の空力性能向上に有効であることが示された。成果は国内学会の招待講演で 1 件発表し、国際論文に 1 件が採択された(平成27年度掲載予定)。

    Through investigating the effects of subcellular-size structures, fluid and fluctuation on animal locomotion, we propose a novel scaling law-based theory, namely the bio-multi-scaled mechanics to give macroscopic classification of biological fluid dynamics. For micro-mechanical systems, we carried out a mechano-biomimetic study of the mechanisms associated with cell motion control and force sensing, and succeeded in manufacturing the mechano-bio-materials for cell culture. For macro-mechanical systems, we developed a bio-inspired flight simulator to integrate external flight dynamics and inner working system, and built up a low-speed wing tunnel equipped with DPIV flow measurement system. A systematic study of insect flights unveiled robustness mechanisms in terms of wing morphology and flapping motion, flight stability and control. We further succeeded in developing two-winged flapping micro air vehicles and bio-inspired rotors applicable to drones and micro-wind turbines.

    Aiming to develop small flapping aerial robots capable of hovering flight, we measured wing motions and shapes of a real hummingbird in hovering flight using multiple high-speed video cameras and motion analysis software. To realize wing deformation like the real hummingbird wing in artificial wings with light-weight structures and mechanisms, the wing films was relaxed in order to enhance passive feathering deformation. As a result, the wing with the relaxed film generated higher average lift than the wing with a tight film, which was comparable to the body weight of the hummingbird. The relaxed film also improved efficiency represented as a ratio of average lift to input power.

    平成18年度の研究では,昆虫の羽ばたき飛行において翅の受動的な弾性変形が飛行運動に大きく影響することを示し,チョウの翅のモデルとして薄膜と翅脈からなるプラスチック製の柔軟人工翅の製作方法を新たに開発した.平成19年度は,人工翅の製作方法を実用レベルまで発展させて実験用人工翅を設計し,チョウと同じサイズ,重さ,羽ばたき周波数を持つ人工翅付羽ばたき機の自由飛行を実現した.平成20年度は,翅脈形状の異なる2種類の人工翅について羽ばたき機の飛行運動を比較し,チョウの翅脈形状と飛行運動の関係を明らかにした.さらに実際のチョウの飛行との比較を行い,羽ばたき機で得られた実験結果が実際のチョウに適用できることを示した.
    人工翅として実際のアゲハチョウと同様の翅脈太さを持つ基準人工翅と,前縁と胴体側のみに翅脈をもち翅面内に翅脈を持たない無翅脈人工翅を製作した.基準人工翅を実装した羽ばたき機は,前進飛行させると羽ばたきに同期して体が上下し,その結果,翅付け根における迎え角が0°から40°の範囲で変化した.この迎え角変化が,打ち下ろし中の翅の揚力係数を定常流中よりも大きく増大させることを示した.一方,無翅脈人工翅の場合は,体の上下運動が小さく,翅付け根における迎え角変化が基準人工翅よりも小さかった.その結果,打ち下ろし中の翅の揚力係数は定常流中の揚力係数と同じ程度であった.これは,翅脈がないことで翅面がフェザリング変形し,体の上下運動を引き起こすほどの空気力を発生しないことに起因すると考えられる.以上より,チョウの翅脈は翅面のフェザリングを抑制し,体の大きな上下運動をもたらし,打ち下ろし中の大きな揚力係数を実現する機能を持つことが示された.実際のアゲハチョウの飛行においても羽ばたきに同期した体の上下運動や迎え角変化が観察され,羽ばたき機での実験結果が妥当であることが示された.
