Description
本出願は、2019年4月25日に出願された米国仮出願番号62/838,773の利益を主張し、この参照によりその全体が組み込まれる。本出願は、2020年2月28日に出願された米国仮出願番号62/983,445の利益を主張し、この参照によりその全体が組み込まれる。
[1.概要]
[2.効果]
本航空機100は、機体、傾斜機構、ペイロードハウジングを備え得り、オプションで、衝撃減衰器、地上支持部材(例えば、支柱)のセット、動力源のセット、および制御要素のセットを備え得る。しかし、本航空機100は、他の適切な構成要素のセットをさらに備え得る。
ある具体例では、傾斜軸は、揚力および/または推力の中心からオフセットされ、キャビン領域の外側に配置され、それでも、前進飛行中の抗力ベクトルと実質的にアライメントされる推力ベクトル、および、ホバリング時にCoGと実質的にアライメントされる揚力ベクトルを供給する。第2の具体例では、垂直/縦方向平面の傾斜軸を通ってCoGから延びる線は、垂直および/または縦方向軸に対して45度の角度を画定する。第3の具体例では、傾斜軸は、重心の後方および上方(および/または前方および下方)にゼロ以外の角度(例えば、45度)で配置され得り、そのため、すべてのロータの平均推力中心が、ホバリング飛行と前進飛行の両方で重心と、なおもアライメントされ得る。
