The invention provides an amphibious universal aircraft landing gear arrangement structure. Wings of the amphibious general-purpose aircraft are arranged in an upper single wing mode, the layout of a front landing gear and a main landing gear is adopted, and a front three-point retractable landing gear is adopted. The nose landing gear is mounted on the nose, is folded forwards or backwards along the course and is matched with the nose and the ship bottom in shape; the main undercarriage adopts a high-strut and narrow-wheel-track undercarriage structural form and is arranged at the positions, higher than the waterline of the ship bottom structure of the aircraft, of the two sides of a fuselage of the amphibious general-purpose aircraft, the main undercarriage achieves the folding and unfolding functions through a conical folding and unfolding path, and the main undercarriage is higher than the waterline of the ship bottom structure of the amphibious general-purpose aircraft after being folded. And the retraction path does not damage the integrity of the lower edge of the fairing and does not reduce the pneumatic and hydrodynamic performance of the aircraft. The problem that the main landing gear of the amphibious general-purpose aircraft is difficult to arrange is solved.

    本发明提供一种水陆两栖通用飞机起落架布置构型。所述的水陆两栖通用飞机的机翼采用上单翼布置,前、主起落架的布局,采用前三点、可收放式起落架;前起落架安装在机头沿航向向前或向后收起,匹配机头船底外形;主起落架采用高支柱、窄轮距起落架结构形式并布置在水陆两栖通用飞机的机身两侧高于飞机的船底结构水线的位置,主起落架通过锥形收放路径实现收起、放下功能,收上后高于水陆两栖通用飞机的船底结构水线,而且收放路径不破坏整流罩下沿完整性,不降低飞机气动、水动性能。本发明解决水陆两栖通用飞机主起落架布置困难的问题。
