The invention provides a Y/YB series airplane fire extinguishing platform. The Y/YB series airplane fire extinguishing platform comprises two front supports, two rear supports, a front corner box and a rear corner box. The front corner box and the rear corner box are oppositely arranged; the front corner box and the rear corner box are fixedly connected through a base and used for balancing gravitational torque generated by the self weight of the fire extinguishing bomb to the front beam and the rear beam; the two bases are symmetrical about the symmetry axis of the aircraft body; two fire extinguishing bombs are arranged at the lower part of the belly, and the other two fire extinguishing bombs are respectively arranged at the lower parts of the left and right wings; the hanging frame is provided with a fuselage belly reinforcing structure, and the fuselage belly reinforcing structure comprises longitudinal reinforcing structures arranged on the front beam and the rear beam respectively, a transverse reinforcing structure arranged between the longitudinal reinforcing structures and end transverse reinforcing parts arranged between the two ends of the longitudinal reinforcing structures respectively; the device is used for balancing lateral bending moment generated by inertia moment and turning of a fire extinguishing bomb mounted on the belly of the aircraft due to gravity of the fire extinguishing bomb during flight during normal flight of the aircraft.

    本发明提供了一种Y/YB系列飞机灭火平台,包括两个前支座、两个后支座、前角盒以及后角盒;前角盒与后角盒相对设置;前角盒和后角盒之间通过底座固定连接,用于平衡灭火弹自重对前、后梁产生的重力矩;两个底座关于飞机机身的对称轴对称;两个灭火弹设置在机腹下部,另外两个灭火弹分别设在左右机翼下部;所述挂架上设有机身腹部补强结构,所述机身腹部补强结构包括分别设在所述前梁和后梁上的纵向加强结构、设在纵向加强结构之间的横向加强结构以及分别设在纵向加强结构两端之间的端部横向加强部;用于平衡飞机正常飞行时,机腹挂载的灭火弹因自身重力、飞行时沿航向的惯性力矩和转弯产生侧向弯矩。
