摘要
现有登机桥在正常靠接B787机型的前门时,因飞机迎角传感器与登机桥左遮篷缓冲器之间的距离仅为20~30mm,在不规范的靠接操作中极易造成遮篷与飞机迎角传感器的碰撞,对靠桥操作人员的要求较高。许多机场靠接B787机型时,只靠接飞机中门,未靠接前门,极大影响旅客服务体验。根据冲量定理,提出增加靠接时间,以降低登机桥与迎角传感器发生碰撞时产生的冲击力。通过增加登机桥左侧遮篷与迎角传感器Z向的安全缓冲距离,并提出4种有效解决方案。最后从干涉风险、坠落风险、接机难度、实施难度4个方面分析比较,决定采用在接机口前沿增加100 mm过渡梁的结构设计改进方法,即能够有效消除登机桥与迎角传感器的干涉风险,也可以提升飞机服务保障质量和效率。
When the existing boarding bridge is normally abutting the front door of the B787 aircraft,the distance between the aircraft angle of attack sensor and the left canopy buffer of the boarding bridge is only 20~30 mm,which is extremely easy in irregular abutting operations.The collision between the canopy and the aircraft\s angle of attack sensor is caused,and the requirements for the bridge operator are relatively high.When many airports dock with the B787,they only dock at the middle door of the aircraft and do not dock at the front door,which greatly affects the passenger service experience.According to the impulse theorem,increasing the contact time is proposed to reduce the impact force when the boarding bridge and the angle of attack sensor collide.By increasing the safety buffer distance between the left canopy of the boarding bridge and the Z direction of the angle of attack sensor,four effective solutions are proposed.Finally,from the four aspects of interference risk,falling risk,difficulty in picking up the plane,and difficulty in implementation,it is decided to adopt the structural design improvement method of adding a 100 mm transition beam at the front of the pick-up port,which can effectively eliminate the interference between the boarding bridge and the angle of attack sensor.Risks can also improve the quality and efficiency of aircraft service assurance.
