Arc frame opening degree control method in aircraft canopy remanufacturing process

The invention provides a method for controlling the opening degree of an arc frame in the remanufacturing process of an aircraft canopy, and belongs to the technical field of aerospace. The method comprises the steps of positioning and fixing a canopy framework, adjusting the thickness of an arc frame middle layer, excessively filling a sealant, installing a positioning bolt group, progressively installing arc frame bolts, curing, fastening, carrying out loosening inspection and the like. According to the method, the thinking mode that in an original canopy arc frame opening degree control method, the total thickness of arc frame middle layer parts is firstly determined, and then assembling is conducted is abandoned; according to the method, assembling is conducted firstly, the tightness of the bolts is adjusted, so that the sealant is extruded to flow, the thickness is automatically adjusted to be in a reasonable gradual change state, the ideal expected effect that bolt holes in all bolt installation positio
