The invention relates to a detection method for a round opening of an air inlet of an airplane. A detection device comprises an outer shape clamping board and an inner shape detection clamping board,wherein an inner shape surface of the outer shape clamping board is matched with an outer shape surface of the air inlet of the air plane, an outer shape surface of the inner shape detection clampingboard is matched with an inner shape surface of the air inlet of the airplane, the inner shape detection clamping board is fixed in the outer shape clamping board, equally spaced annular gaps exist between the outer shape clamping board and the outer shape surface of the inner shape detection clamping board, and the outer shape surface of the inner shape detection clamping board is a round reference surface. The detection method comprises the following steps of fixing the air inlet of the air plane to a fixture; inserting the round opening of the air inlet of the airplane into the annular gapsbetween the outer shape clamping board and the inner shape detection clamping board; and measuring a radial gap value between the round reference surface of the inner shape detection clamping board and the inner shape surface of the air inlet of the air plane to judge whether the round opening of the air inlet of the airplane is qualified or not according to the gap value.
Description
technical field [0001] The application relates to the technical field of aircraft assembly, in particular to a detection method applicable to the circular opening of an air intake of an aircraft. Background technique [0002] The air intake is one of the most critical parts of the aircraft power structure. The shape of the opening of the air inlet determines the important parameters of the aircraft flying at high altitude. In order to ensure the smooth and efficient flight of the aircraft in the air, there are strict requirements on the shape of the opening of the air inlet of the aircraft. When assembling the aircraft, it is necessary to inspect the circular opening of the air inlet to check whether the manufacturing error of the circular opening is out of tolerance. Existing detection methods generally need to be coordinated with the components at the docking point to know the results, and the assembly results cannot be fed back to the design in time for improvement. At...
