![]() Since the sensors work with narrow-band blue light, interfering ambient light can be filtered during image acquisition. The result, even with reflective surfaces and complex-shaped objects with complicated undercuts, is a mesh of complete measuring data without holes or faulty points. As the beam paths of both cameras and the projector are calibrated in advance, 3D surface points from three different ray intersections can be computed. They project precise fringe patterns onto the surface of an object which are recorded by two cameras based on the stereo camera principle. Due to their robust design with protected optics, encapsulated electronics and a self-monitoring sensor, the measuring systems are also ideal for use in harsh industrial environments.Īll sensors of the ATOS product range operate according to the Triple Scan Principle. Within minimum time, an easily understandable overview of the dimensional accuracy of the just produced, maintained or repaired part is created. The resulting point cloud can directly be compared in the GOM software using a surface comparison with the CAD model or data from previous measurements. ![]() This means, that a turbine blade is completely digitised in 3 minutes, a complete blisk in about an hour. The sensor transmits the data via fibre optic cable. A total of 120 images per second can be triggered. A scan in one measuring position takes only 0.2 seconds. The 2019 releases of ATOS Professional and GOM Inspect Professional feature new modules that, among other things, make it much easier to analyse demanding edge geometries.Īll ATOS 5 scanners excel by their high digitising speed and high-precision measuring data. Eventually I made some jigs that help me get good, consistent airfoils on. Using ATOS technology partnered with techniques such as additive manufacture and adaptive machining can lead to considerable savings.Īlong with the introduction of ATOS 5 for Airfoil, GOM offers a corresponding software update. For years, I always wanted some sanding jigs to help me get good airfoils on fins. The costs associated with the MRO sector are large, replacing turbine blades can exceed €10,000. The ATOS 5 for Airfoil sensor also excels during maintenance and repair of nozzle guide vanes. Their complex-shaped edges and surfaces have been a challenge during 3D digitisation until now. At the same time, the ATOS 5 for Airfoil is particularly well-suited for the inspection of turbine components produced for the aerospace industry, such as blades, blisks and air-conducting structures. With the introduction of a 3D measuring machine particularly designed for small parts with a size of 100 x 70mm2 to 400 x 300mm2, GOM closes the gap in the lower measuring area. While the all-rounder ATOS 5 successfully performs a wide range of measuring tasks in measuring areas from 170 to 1,000mm in length, the ATOS 5X is particularly effective when used for large surfaces and parts due to its strong, focused light. The ATOS 5 for Airfoil expands the ATOS 5 series in the measuring area for small parts. The other force acting on an aircraft during flight is its weight, which is a body force and not an aerodynamic force.GOM has introduced the new ATOS 5 for Airfoil optical measuring machine that is particularly suitable for the inspection of airfoil components like turbine blades, nozzle guide vanes or blisks in the aerospace and power generation industries. The aerodynamic force on a powered airplane is commonly represented by three vectors: thrust, lift and drag. The force created by propellers and jet engines is called thrust, and is also an aerodynamic force (since it acts on the surrounding air). In addition to these two forces, the body may experience an aerodynamic moment. lift is the force component perpendicular to the direction of relative motion.drag is the force component parallel to the direction of relative motion,.This aerodynamic force is commonly resolved into two components, both acting through the center of pressure: : 14 : § 5.3 When an airfoil (such as a wing) moves relative to the air, it generates an aerodynamic force in a rearward direction, at an angle determined by the direction of relative motion. The net aerodynamic force on the body is equal to the pressure and shear forces integrated over the body's total exposed area. Pressure acts normal to the surface, and shear force acts parallel to the surface. While the nominal airfoil produces a lift coefficient equal to approximately 1.70, the aircraft is fitted with a leading edge slat as well as a full-span, fixed, trailing edge flap which serves to increase the effective camber of the airfoil section and increase the maximum lift coefficient further. ![]()
