Outline of Research at the Start

昆虫飛行の翼・胴体の柔軟構造と飛行 ロバストネスの相関を運動・力学・制御の統合的研究により解明することで、“墜ちない” 安全安心なドローンなど無人飛行体のバイオミメティクス基本設計指針の創出を目指す。外乱に強い昆虫飛行の空気力学ロバスト性(なぜ失速しないのか)と飛行制御ロバスト性(なぜ 安定飛行できるのか)を解明するために、自然外乱を模倣可能な低速風洞での昆虫飛行時の翼・胴体の運動と変形の同時計測システムと、昆虫飛行の柔軟翼・胴体の運動・力学・制御の多力学連成シミュレータを開発・統合するとともに、昆虫翼・胴体の柔軟構造機構が生み出す胴体主導の飛行制御則を明らかにする。

Outline of Final Research Achievements

Insects power and control their flight by flapping their wings. Insect flights are diverse but robust relying on the integration of different flexible structures including wings, exoskeletal elements, wing-hinges, musculoskeletal elements, and sensors. In this study, to unlock how insects execute complex maneuvers in turbulent environments, we developed an integrated computational platform of insect-inspired flight systems and explored unraveling a passive and active mechanism strategy of how flexible wing-body structures work interactively to achieve a systematically efficient and robust flapping-wing dynamics and aerodynamics as well as flight control. An extensive investigation was further undertaken on the insect flight strategies in terms of robustness, intelligence and flexible-structure-based multi-functionalities. Our results provide a novel biomimetic design of the insect-inspired micro air vehicles / drones with capabilities to perform a variety of complex maneuvers.

Academic Significance and Societal Importance of the Research Achievements

本研究は、外乱に強い昆虫羽ばたき飛行の空気力学ロバスト性(なぜ失速しないのか)と飛行制御ロバスト性(なぜ安定飛行できるのか)を解明したことにより、様々な自然環境に強く、“墜ちない”生物規範型羽ばたきロボットやドローンなど次世代“安全安心”無人航空機の研究開発に、一つのバイオミメティクス設計指針を提供した。また、昆虫のもつ翼と胴体と筋骨格系の柔軟構造が知能構造として生み出す飛行制御則は、小型飛行体の安定性・操縦性トレードオフを打破する一つのキーになる可能性を示唆し、それが生物飛行制御のロバスト性の解明だけでなく、次世代ドローンや空飛ぶ車に革新的な設計指針をもたらすことが期待される。
