Germany's Lufthansa Asia's largest repair base adheres to rigorous work purposes. It needs to perform three-dimensional reverse engineering of the air inlet cavity wall of the aircraft engine, obtain high-precision three-dimensional data for mold processing, and reduce the difficulty of subsequent repair work.

Practical problems 

1. The volume of the air inlet cavity wall of the aircraft engine is large, and the traditional measurement method is too low in efficiency and low in accuracy, which makes it difficult to reverse design and modeling in the later stage. Waste too much human and material resources.

2. The curvature of the outer surface of the air inlet cavity wall of the aircraft engine is difficult to measure by manual comparison. The customer requires that complete and accurate data can be obtained in a short time, so that the follow-up work can be carried out quickly and the quality of service can be ensured.

Holon solutions

The customer hopes to be able to obtain complete and accurate 3D data of the air inlet cavity wall of the aircraft engine in a short time. Hualang 3D proposes a solution according to the problem faced by the customer: using the camera-based 3D scanner HL-3DS+ to quickly and accurately The three-dimensional data of the air inlet cavity wall of the engine was obtained, and the scanned 3D data was imported into the software to fit the SLT triangle mesh surface, and then imported into the three-dimensional design software for reverse design. The product structure design and improvement have improved the efficiency, the follow-up work can be carried out quickly, and the service project has been completed within the specified time.
