Project Features

High precision complex pneumatic surface machining

According to the target airfoil, wing or blade profile, precision 3D processing is carried out, and the leading edge, trailing edge, curvature change area and key aerodynamic surface are strictly controlled to improve the consistency between the actual shape of the model and the theoretical profile.

High stiffness metal structure

The main body of the model made of metal material can maintain good structural stiffness and geometric stability under high wind speed and complex load environment, and provide a reliable basis for high repeatability wind tunnel test.

Integrated design of internal structure

According to the requirements of pressure measuring pipes, sensors, mounting shafts and other internal components, special cavities, channels and strengthening structures can be designed inside the model to realize internal functional integration while ensuring the external pneumatic shape.

Multi-point pressure measurement capability

According to the test requirements, different numbers and positions of surface pressure measuring holes can be arranged, and combined with the internal pressure channel or pipeline system, the pressure distribution measurement of different positions of the airfoil or model can be realized.

sectional modular structure

For large or complex models, multi-segment combinations can be used to take into account the processing realizability, transportation convenience and on-site installation requirements, and to ensure the continuity of the shape and assembly accuracy between the segments.

Highly adaptable installation interface

The special shaft, flange, support and connection interface can be designed according to different wind tunnel support systems and test bench structures to realize the rapid adaptation between the model and the existing equipment in the laboratory.
