摘要:为实现在无人机小尺寸空间内完成切割伞绳和推销的功能，根据总体技术要求，设计了一种推销切割多功能一体化结构的电切割器，以实现轴向推销和径向切割伞绳、电缆、金属丝等功能，并对影响其功能的主要参数进行了设计及试验验证。试验结果表明：当切割器输出装药为18mg的高氯酸钾/亚铁氰化铅点火药、砧板为1.5mm厚T2M铜带的环形垫圈、环刀材料为T7(A)M银亮钢时，在+55℃、-50℃和常温条件下，切割器均能实现可靠切割Φ3.5mm锦丝绳及推销功能，且残骸结构完整。
Abstract:In order to realize the function of cutting umbrella rope and pushing pin in the small space of the drone, an electric cutter with multifunctional integrated structure for pushing and cutting was designed according to the general technical requirements, which can realize axial pushing pin and radial cutting of umbrella ropes , cables , metal wire and other functions. The main parameters affecting the realization of its function were designed and verified by tests. The test results show that when the cutter output charge is potassium perchlorate/lead ferrocyanide ignition powder of 18mg, the cutting board is an annular washer of T2M copper strip with 1.5mm thickness, and the ring knife material is T7(A)M silver bright steel, the cutter can cut Φ3.5mm brocade wire rope and push pin reliably under the conditions of +55℃, -50℃ and normal temperature, and the structure of the wreckage is complete.
