Abstract

A locating device for accessory mounting of an A-320 aircraft radome is in a truncated conical shell shape; the internal surface of the locating device is completely fit with the external surface of an open end of the radome; corresponding holes are formed in positions, corresponding to accessory mounting holes in the radome, of the locating device; a solid structure of glass fiber fabric steeped with epoxy resin is arranged in a general position of a conical shell; a solid structure of the glass fiber fabric steeped with the epoxy resin is arranged at an accessary fastener mounting part; the glass fiber fabric steeped with the epoxy resin is arranged on the internal surface and the external surface of an easy deformation part; and a flexible NOMEX honeycomb core is arranged in the middle of the easy deformation part. The invention further relates to a fabrication method of the device. The device can keep a consistent structure with the original structure completely, fully meets locating requirements, is precise in location and quick and convenient to mount and dismount, saves time and labor, has no special requirements on skills of a worker and fills a blank in the field domestically at present.

Description

technical field [0001] The invention relates to a positioning device for installing an accessory of an aircraft radome, in particular to a positioning device for installing an accessory of an A-320 aircraft radome. The invention also relates to a method of making said device. Background technique [0002] The radome is the radome installed at the front of the aircraft. It not only needs to maintain the aerodynamic appearance of the aircraft and meet the requirements for structural strength, but it is also a functional part, that is, it must meet the electrical performance requirements of the radar. Radar waves are penetrating enough for him. The A-320 aircraft radome is a new type of radome launched by Airbus. It has outstanding electrical properties. It is a class A radome with a wave transmission rate of 90%. In comparison, Boeing is a class B and C. The wave transparency rate can only reach 70% and 80%. [0003] During aircraft operation, the nose radome is most vulner...
