Production Number: 103 Model Name: Falcon 6.1 Wingspan: 1080mm Overall Length: 430mm Power Source: 240mAh 2S LiPo Total Weight: 182grams CG: 100.7mm Drive System: Planetarygear 1/114 Gear Ratio Power Source: 4300kv Small Drone Motor with ESC Control System: Elevon Control System ,Two YSIDO_4.3g Digital Servos move the main wings up and down to controll and pitch. Gliding Wing Locking System (GWLS): The wing is locked in the gliding position by using a servo-driven hook to hold the rotating flapping drive wheel in place. Fuselage: LWA-PLA 3D-printed,LWA-PLA and TPU 3D-printed head Main Wing: LWA-PLA EK-EB EAGLE airfoil ribs and front cover with upper and lower surface film planking, Φ2.5 and Φ1.8 and Φ1 CR spars Tail: Fixed V-tail stabilizer with small vertical tail (1mm-thick styrene sheet facing,50-degree V angle downward) Falcon 6.1はサーボ駆動のフックを使用して、回転する羽ばたき駆動輪を所定の位置に保持し、主翼を滑空位置にロックする機構を備えています。そして、シンプルな捩れ翼羽ばたき機構と左右動作の作動が少ないWatts-Link Flapping-Arm Mechanism を搭載したオーニソプターです。 鳥の飛行で重要な点は効率良く羽ばたく翼と高度を落とさずに滞空する滑空性能と機動的な姿勢制御です。 従来のGLDABシステムでは翼をグライディング位置に固定する確度が低く、成功確率は20%から60%程度でソアリングが困難でした。 これを解決する目的でサーボ駆動のフックで、回転する羽ばたき駆動輪を所定の位置に保持し、主翼を滑空位置にロックする機構を開発しました。 機動的な姿勢制御を実現するために私は、翼の角度を調整することで、羽ばたき翼航空機の飛行を制御する簡単な方法を開発した。 多くの鳥類は、羽ばたき飛行中は尾翼を閉じたままにし、飛行姿勢をほぼ主翼と胴体だけで制御しています。 急旋回、減速、離陸、着陸といった飛行姿勢の急激な変化時や、ホバリングや滑空など高い揚力を必要とする機動時には、主翼と尾翼を最大限に広げ、翼面積を増加させます。 これらの観察結果に基づき、鳥の定常飛行を模倣する場合、主翼の調整だけで飛行姿勢を制御でき、それによってシンプルで軽量な構造が可能になるとの考えから、この機構を応用したワイドボディ・ロングリンクアーム機構のオーニソプターを作りました。 2026年10月27日 The Falcon 6.1 features a mechanism that uses a servo-driven hook to hold the rotating flapping drive wheel in place and lock the main wing into the gliding position. It is an ornithopter equipped with a simple twisted-wing flapping mechanism and a Watts-Link flapping-arm mechanism that requires minimal lateral movement. Key aspects of bird flight include efficient flapping wings, gliding performance that allows for sustained flight without losing altitude, and agile attitude control. Conventional GLDAB systems had low accuracy in fixing the wings in the gliding position, with a success rate of only about 20% to 60%, making soaring difficult. To address this issue, I developed a mechanism that uses a servo-driven hook to hold a rotating flapping drive wheel in a predetermined position, thereby locking the main wing into the gliding position. To achieve agile attitude control, I developed a simple method for controlling the flight of a flapping-wing aircraft by adjusting the wing angle. Many birds keep their tail surfaces closed during flapping flight, controlling their flight attitude almost entirely with their wings and fuselage. During sudden changes in flight attitude—such as sharp turns, deceleration, takeoff, and landing—or during maneuvers requiring high lift, such as hovering or gliding, they spread their wings and tail surfaces to the maximum to increase wing area. Based on these observations, and on the idea that mimicking steady-state bird flight would allow flight attitude to be controlled solely by adjusting the main wings—thereby enabling a simple and lightweight structure—we built a wide-body, long-link-arm ornithopter utilizing this mechanism.
