The invention discloses a helicopter integrated armored floor, and relates to the field of aviation military equipment. The invention aims to overcome the defects of large weight, large occupied space, incompact structure, unreasonable system design and the like of a helicopter floor draping armor protection mode. The helicopter integrated armored floor comprises a sandwich structure formed by bonding two layers of mould-pressed fiber reinforced resin bulletproof plates and a honeycomb core, a bulletproof ceramic layer and an outer side fiber winding layer. The sandwich structure and the bulletproof ceramic layer are bonded to form a main body structure, and high-performance fibers are alternately wound on the outer layer of the main body structure in a 0-DEG /90-DEG direction by adoptinga wet winding process to form an integrated structure. The integrated armored floor has a bulletproof function while meeting the bearing requirement of A helicopter cab floor. The bulletproof ceramicside of the integrated armored floor faces downwards, is fixed to a longitudinal beam and a partition frame of a bottom supporting structure in a traditional helicopter floor installation mode, and can be widely applied to cab protection of armed helicopters.

    本发明公开了一种直升机集成装甲地板,涉及航空军用装备领域。本发明旨在解决直升机地板披挂装甲防护方式存在的重量大,空间占用多,结构不紧凑,系统设计不合理等缺陷。发明包括两层模压的纤维增强树脂防弹板与蜂窝芯子粘结而成的夹层结构,防弹陶瓷层和外侧纤维缠绕层。夹层结构与防弹陶瓷层通过粘结形成主体结构,高性能纤维采用湿法缠绕工艺以0°/90°方向交替缠绕于主体结构外层形成一体化整体结构。集成装甲地板满足直升机驾驶室地板承载要求的同时还具有防弹功能。集成装甲地板的防弹陶瓷一侧向下,通过传统直升机地板安装方式固定于底部支撑结构的纵梁、隔框上,可广泛应用于武装直升机的驾驶室防护。
