The invention belongs to a helicopter fairing design technology, and relates to a detachable fairing of a helicopter. Comprising a left detachable fairing, a right detachable fairing, a middle quick-release fairing and a guide limiting device. According to the invention, a block type design is adopted, the fairing is divided into a fairing with two functions of general disassembly and quick disassembly, and the fairing is respectively corresponding to two use requirements of aircraft overhaul or engine troubleshooting and airborne equipment regular maintenance and troubleshooting. The middle quick-release fairing adopts a composite sandwich structure, so that the weight of the fairing structure can be reduced by about 20%, and the manufacturing period of the fairing is shortened by about 50%. The quick-release design of the quick-release cloud-shaped lock and the guide limiting device is selected, on the premise that the flight safety of the airplane is guaranteed, compared with a common bolt connection mode, the fairing dismounting and mounting efficiency can be effectively improved by more than 10 times, the service life of a fastener is effectively prolonged, the attendance rate of the airplane is guaranteed, and the service life of the fairing is prolonged. And the economic benefit and the civil market competitiveness of the airplane of the model are improved.

    本发明属于直升机整流罩设计技术,涉及一种直升机可拆卸整流罩。包括:左侧可拆卸整流罩、右侧可拆卸整流罩、中部快拆整流罩、导向限位装置。本发明采用了分块式设计,将整流罩分为一般拆卸和快速拆卸两种功能整流罩,分别对应“飞机大修或发动机故障排除”与“机载设备定检维护及故障排查”两种使用需求。中部快拆整流罩选用复合材料夹层结构,可降低整流罩结构重量20%左右并缩短整流罩制造周期近50%。而选用快卸云形锁及导向限位装置的快拆设计,在保障飞机飞行安全的前提下,较普通螺栓连接方式可有效提升整流罩拆卸、安装效率近10倍以上,且有效延长了紧固件使用寿命,保障飞机出勤率,提升了该型号飞机经济效益及民用市场竞争力。
