The invention provides an electrorheological damping aircraft nose landing gear and an aircraft. The landing gear comprises a damping cylinder body; one end of the piston rod is slidably arranged in the damping cylinder, the other end of the piston rod is connected with an aircraft wheel, and a supporting shoulder is arranged in the middle of the piston rod; the electrorheological damping assembly comprises a plurality of electrorheological damping units which are stacked on the supporting shoulder; each electrorheological damping unit comprises electrorheological elastomers, a first electrode plate and a second electrode plate, and the adjacent electrorheological elastomers share one electrode plate; each first electrode plate is arranged on the inner wall of the damping cylinder body through a first insulating snap ring seat, and the end away from the snap ring seat is in sliding contact with the outer wall of the piston rod; each second electrode plate is arranged on the outer wall of the piston rod through a second insulating snap ring seat, and the end away from the snap ring seat is slidably contacted with the inner wall of the damping cylinder body; the power supply and the two electrodes are electrically connected with the piston rod and the damping cylinder body respectively to form a conductive loop; the rigidity can be adjusted in a self-adaptive mode, and the stability and comfort of aircraft operation are improved.

    本发明提供一种电流变减震飞机前起落架及飞机,起落架包括:减震缸体;活塞杆,一端可滑动设在减震缸体内,另一端连接有飞机机轮,其中部设有支撑台肩;电流变减震组件,包括若干个电流变减震单元,叠设在支撑台肩上;电流变减震单元包括电流变弹性体、第一电极板和第二电极板,相邻的电流变弹性体之间共用一个电极板;每个第一电极板通过第一绝缘卡环座设在减震缸体内壁,远离卡环座端与活塞杆外壁可滑动触接;每个第二电极板通过第二绝缘卡环座设在活塞杆外壁,远离卡环座端与减震缸体内壁可滑动触接;电源,两电极分别与活塞杆和减震缸体电性连接,并构成导电回路;本发明可自适应调整其刚度,提升飞机运行的稳定性和舒适性。
