The invention provides a design method of an openable side window mechanism of an airplane, the side window mechanism comprises an upper plane four-bar mechanism and a lower plane four-bar mechanism, and the two plane four-bar mechanisms are connected through a torsion bar to realize synchronous movement. The method comprises the steps that a front lower lock column, a rear lower lock column, a rear upper lock column and a limiting piece are arranged at the positions, close to a stiffening beam, of the four corners of a fuselage side window opening correspondingly; the upper track is designed to be a straight track and installed at the position of an upper beam of a fuselage side window opening, the lower track is installed at the position of a lower beam of the fuselage side window opening, and the linear section of the lower track is completely parallel to the upper track. Front and rear upper rollers are arranged at the connecting positions of the front and rear upper latch hooks and the upper track; and front and rear lower rollers are arranged at the connecting positions of the front and rear lower latch hooks and the lower track. The method has the remarkable advantages of improving the operation flexibility of flight crew, enhancing the flight safety, improving the airplane performance, and being environmentally friendly, flexible in design, innovative in technology, convenient to maintain and the like.
本发明提供一种飞机可开启侧窗机构设计方法,侧窗机构包括上、下两组平面四杆机构,通过扭力杆将两组平面四杆机构进行连接以实现同步运动,该方法包括将前下锁柱、后下锁柱、后上锁柱和限位件分别布置在机身侧窗开口四个边角靠近加强梁的位置;设计上轨道为平直轨道,将其安装在机身侧窗开口上部梁位置,将下轨道安装在机身侧窗开口下部梁位置,其直线段与上轨道完全平行;在前、后上锁钩与上轨道的连接位置配置前、后上滚轮;在前、后下锁钩与下轨道的连接位置配置前、后下滚轮。本发明在提高机组人员操作灵活性、增强飞行安全性、提高飞机性能、环境友好性、设计灵活性、技术创新和维护方便性等方面具有显著的优点。
