Outline of Final Research Achievements

The author has developed a new method for the aerosol observation and sample return using the combination of a balloon and a glider unmanned aerial vehicle(UAV) in Antarctica. We have used "Two Stage Separation Method" in which the UAV descends down to approximately 12km in alitutde by a parachute after separating from the balloon, and starts autonomous gliding by separating the parachute because of the unknown aerodynamic characteristics at higher altitudes, i.e. low Reynolds number and mid-to-high subsonic region. We have attempted and confirmed effective to estimate aerodynamic characteristics of the UAV at low Reynolds number which corresponds to the glide at higher altitude by using the device named "Parachute Sting Balance (PSB)". We can derive pure aerodynamic forces and moments by subtracting the forces and moments measured at the point where the PSB is attached from the whole aerodynamic forces and moments measured by accelerometers and angular sensors mounted on the UAV.

Academic Significance and Societal Importance of the Research Achievements

高高度における小型無人航空機の飛行データが無く,制御系設計のための空力特性データを取得することは非常に困難であった.筆者が開発した二段階分離法(気球からの分離高度から,空力特性が把握できている高度までパラシュートで一旦降下させる方法)において,今回開発したパラシュートスティングバランスと呼ぶ装置により低レイノルズ数領域における空力特性を推定できるようになったことは大きな意義がある.実験結果からは妥当な結果が得られており,いくつかの実施上の課題が残るものの,推定法としてほぼ確立できたと言える.また,南極観測において定常的に高高度までのサンプル回収ができるようになる意義は大変大きい.
