Highly precise 3D printing

With our specially adapted machines, we take 3D printing to the next level. We are specialized in manufacturing smallest channels and minimal wall thicknesses. In this way, we can create highly functional components which are not possible with traditional manufacturing methods. Through additional topology optimization, we are playing with physics. Changing natural frequencies and heat transfer, invisible material reinforcements are just a few examples of what is possible. In general, there are of course the following advantages: 

  • Design freedom - creating complex geometries that would not be possible through traditional manufacturing
  • Complex shapes - optimization of the internal structure through special grids and bionic shapes with less material
  • Time saving - production in days/weeks instead of months
  • Weight saving - topology optimization leads to minimization of weight

In addition to fluid-dynamic measuring systems, we also build integral components with inherent functions. A popular example of this is components with complex cooling structures. 

FEA possibilities

Vectoflow's engineering and design are complemented and optimized by our in-house finite element analysis (FEA). Whether severe vibration or thermal loads in turbomachinery, aerodynamic or inertial loads in flight applications, our probes and systems are numerically analyzed for their structural integrity.
Modal analyses and special design optimizations are performed to ensure that our measurement system components are outside the resonance zone. Structural analyses ensure the longevity of our probes in operation.

Heat transfer analyses are performed to maximize the performance of our systems in harsh thermal environments.
Our specialized 3D printing expertise is fully exploited by performing topology optimization in the design phase to develop lightweight and bionic probes.
Our expertise also allows the development and simulation of aerodynamic rakes and probes made of plastic and composite materials.

Calibration

For a flow probe to attain its measurement accuracy, calibration is essential. Vectoflow operates two proprietary wind tunnels precisely for this purpose.

The cornerstone of reliable measurement outcomes is the meticulous calibration of the probes. During this process, the relationship between applied pressure and measured speed is established. The probe is situated in a controlled flow field generated within the wind tunnel. By adjusting the angle of attack and rotation, pressures at various measuring points are recorded. Subsequently, calibration factors are derived from this data. When deployed in an unknown flow field, these calibration factors enable the determination of flow speed based on measured pressure.

Central to every calibration is the creation of an optimal free jet—a consistent, homogeneous airflow with minimal turbulence. Powering this process is a 90 kW asynchronous motor, driving two radial compressors via belt drive. The compressed air undergoes refinement in a settling chamber, passing through multiple sieves and rectifiers to achieve homogenization. A series of nozzles with specialized geometry, engineered for low pressure loss, accelerates the compressed air. This setup facilitates the generation of speeds ranging from Mach 2 (0,012 m/s ISA) to Mach 4 (0,99 m/s ISA). To ensure precision, the probes are meticulously positioned to within 337° using a 2-axis traverse, encompassing roll and yaw angles. This meticulous calibration process allows customisation within the speed and angle parameters defined by our customers.
