Pressure measurement model of metal wing
Stable maintenance of aerodynamic shape, accurate acquisition of wing surface pressure distribution
With high rigidity metal structure, precision aerodynamic surface and integrated pressure measuring channel, it provides a reliable model for high repeatability wind tunnel pressure measurement test.
The pressure distribution on the wing surface is a crucial basis for analyzing lift, drag, pitching moment, local loads, and flow separation. The pressure-measurement model must both accurately replicate the theoretical shape and accommodate pressure taps, pressure lines, mounting shafts, and reinforcing structures within its limited internal space.
The metal wing pressure measurement model adopts aluminum alloy, stainless steel and other materials, and obtains high dimensional stability and structural rigidity through precision machining, which is suitable for wind tunnel tests with high requirements for repeatability, air tightness and surface geometric accuracy.
Xi 'an Xinghualang Technology Co., Ltd. can complete the overall structure, internal passage, segment connection, precision machining, surface treatment and installation adaptation of the model according to airfoil, aspect ratio, measuring point scheme, wind tunnel interface and test conditions.
Core technology advantage
01 High-precision pneumatic surfaces-control critical surface manufacturing errors
Three-dimensional modeling is performed based on the target airfoil and wing geometry, with fine machining applied to the leading edge, trailing edge, wingtip, wing root, and regions of curvature variation.
Through surface detection and surface modification, the consistency of physical model and theoretical shape is improved.
02 High stiffness metal body-maintain geometric stability under wind tunnel conditions
The metal structure can maintain good dimensional stability under high wind speed and complex load, which provides the basis for repeated measurement.
Combined with the internal cavity and reinforced structure design, the overall stiffness is taken into account while meeting the measurement function.
03 Multi-point pressure measurement integration-forming a complete pressure acquisition path
According to the number and distribution of measuring points, surface pressure measuring holes are set, and the internal pressure channel, hose space and outlet interface are planned as a whole.
Focus on the processing quality of the pressure measurement hole, pipeline identification and sealing connection, which is convenient for docking with the pressure scanning system.
04 Modular segmented structure-both processing and transportation and on-site assembly
Large or complex wings can adopt a segmented combination scheme to reasonably set the positioning datum and connection structure.
The segmentation ensures continuity of the external shape, assembly accuracy, and ease of disassembly, while supporting adjustments to different test configurations.
05 Wind tunnel interface adaptation-connection support and measurement system
Custom roots and internal connections according to support rods, shafts, flanges, force balance and test bench structure.
Improve model installation efficiency and repeat positioning capability through interface co-design.
