Description
(構成及び機能)
図1は本発明の第1の実施形態に係る降着装置としてのスキッドを備えた回転翼航空機の側面図であり、図2は図1に示す回転翼航空機に取付けられるスキッドの構造を示す斜視図である。
このため、スキッド4を取付けた回転翼航空機1によれば、従来の金属製のスキッドを取付けた回転翼航空機に比べて軽量化を図ることができる。また、変位に応じて非線形に変化する剛性をクロスチューブ11に付与することによって、回転翼航空機1の着陸時における十分なエネルギ吸収と、胴体3と地面30との間における接触の回避を一層確実に両立させることができる。
図8は本発明の第2の実施形態に係る降着装置としてのスキッドの構成を示す正面図である。
(第3の実施形態)
図9は本発明の第3の実施形態に係る降着装置としてのスキッドの構成を示す正面図である。
以上、特定の実施形態について記載したが、記載された実施形態は一例に過ぎず、発明の範囲を限定するものではない。ここに記載された新規な方法及び装置は、様々な他の様式で具現化することができる。また、ここに記載された方法及び装置の様式において、発明の要旨から逸脱しない範囲で、種々の省略、置換及び変更を行うことができる。添付された請求の範囲及びその均等物は、発明の範囲及び要旨に包含されているものとして、そのような種々の様式及び変形例を含んでいる。
