The measurement process

Our mobile team visited the Blades at their base in Northamptonshire, UK to capture highly-accurate data of the Edge 540 using the industry-leading GOM 3D measurement systems structured light (3DSL) measurement system ATOS 5. A combination of Photogrammetry and Scanning was used to capture surface data of the plane. To begin, a series of coded and un-coded markers were placed on and around the aircraft, along with calibrated scale bars which are placed next to the plane to define the relative size.

Using our GOM TRITOP photogrammetry system, multiple images were captured to precisely and accurately triangulate the position of the reference points in 3D space. These coded markers are used to orientate the images together which subsequently position the un-coded markers to a point cloud forming a reference frame of these markers, ensuring the global accuracy of the scan.

Our team then used the ATOS 5 optical scanning system, which projects a three-dimensional structured light (3DSL) fringe pattern onto the aircraft. Using triangulation principles, the sensor accurately measures the divergence and convergence of the pattern, creating a high density point cloud of surface measurements.

Post processing within the GOM software ensures traceability, exporting the data set as a .STL format. Using specialist CAE software, the data is fully aligned and then reverse engineered to produce a CAD model of the Edge 540 for future downstream use in various CAE packages i.e. CAD, FEA etc.

Looking to the future

Moving forward, Physical Digital will be working with The Blades Racing Team as a Technical Partner and supporting them with their ongoing measurement and development needs. Ben Murphy, Lead Pilot commented: “This is a huge partnership for us. Physical Digital are assisting us to reach the next stage in critical development of our Edge 540 Race plane. With accurate data and more precise knowledge of our current aerodynamic strengths and weaknesses we can focus our strategy and align our modification packages. Knowledge = power and hopefully speed and results will follow.”
