3D Model of Aircraft Longeron

3D Model of Aircraft Longeron

Reverse Engineered cracked longeron, designed doubler (splice) and provided adaptive machining 3D model using ZScanner 800, Rapidform XOR software and Solid Edge CAD software.

Client provided: 1. four foot long cracked section of longeron removed from aircraft 2. two foot long plaster cast of inside surface of remaining section of longeron (mating surface for doubler) 3.six foot long pre-machined blank for replacement longeron with integral doubler.

All 3 components were scanned using ZScanner and then modeled (minus crack) using Rapidform to create Parasolid 3D models. Solid Edge was used to 'assemble' 3D models and to design replacement longeron with inegral doubler inside pre-machined blank to insure 100% cleanup and to equalize material removal. Client was pleased with results.

3D Models from CT Scan STL

3D Models from CT Scan STL

Client was very impressed with CT results. 3D models of components revealed significant voids in prototype product. 3D model of assembly revealed interference between prototype components. Client now plans to expand use of Zeiss' X-ray Computed Tomography (CT). Multiple products will benefit from 3D models created from CT scan STL mesh.

Rapidform XOR3 and EXPLORER software modules were used to analyze STL mesh created using Zeiss CT scan technology. STL data was extremely high resolution which allowed creation of very accurate and very detailed 3D models, which enabled determination of cause of product non function and which allowed characterization of voids in material. Dimensional analysis using Zeiss' CAD to scan comparison technology was very beneficial as well.
