The invention discloses a double-supporting-rod statically-determined landing gear and an aircraft comprising the double-supporting-rod statically-determined landing gear, the double-supporting-rod statically-determined landing gear can move between a folded position and a put-down locking position, the double-supporting-rod statically-determined landing gear comprises a buffer supporting column, an upper supporting rod, a lower supporting rod, an upper locking rod, a lower locking rod and a locking spring, and the locking spring is always in a stretching state; and a locking spring, one end of which is connected to the lower lock bar and the other end of which is connected to the lower stay bar, the upper lock bar and the lower lock bar being brought into contact with each other by the tensile force of the locking spring when the double stay statically indeterminate landing gear is in a lowered locking position, thereby maintaining the double stay statically indeterminate landing gear in a locked state. According to the undercarriage, a supporting and locking mechanism composed of the upper supporting rod, the lower supporting rod, the upper locking rod and the lower locking rod is adopted, a static structure can be achieved, and disastrous accidents caused by the fact that one of the two mechanisms cannot be locked or locking of the two mechanisms is not synchronous are effectively avoided.
一种双撑杆静定式起落架和包括该双撑杆静定式起落架的飞机,上述双撑杆静定式起落架能够在收起位置与放下锁定位置之间运动,包括:缓冲支柱、上撑杆和下撑杆、上锁杆和下锁杆、以及锁定弹簧,上述锁定弹簧始终处于拉伸状态,其一端连接至下锁杆,另一端连接至下撑杆,在处于放下锁定位置时,通过上述锁定弹簧的拉伸力,将上锁杆与下锁杆彼此抵接,由此将上述双撑杆静定式起落架维持为锁定状态。本申请的起落架采用由上撑杆和下撑杆、上锁杆和下锁杆构成的一套支撑锁定机构,能够实现静定式结构,并且有效地避免以往的两套机构中的一套机构无法上锁或者两套机构的上锁不同步所导致的灾难性事故。
