Description

Technical Field

[0001] The utility model relates to the technical field of spar production, in particular to a protection structure for forming a combined aircraft spar. Background Technique

[0002] At present, the wings of some aircraft adopt integral spars. Such spars are integrally die-forged from aviation aluminum alloy. After forming, the temperature is relatively high, and they need to be placed on a protection rack and left to air-cool statically before machining can be carried out. At present, most of the used spar protection racks are fixed, occupying a large area, not easy to store when not in use, and unable to stack between multiple protection racks, which will occupy more production sites. Therefore, we propose a protection structure for forming a combined aircraft spar. Content of the Utility Model
