Composite material wing pressure measurement model
Lightweight load and stiffness can be designed to serve complex wing aerodynamic tests.
Carbon fiber composite material molding, metal interface integration and pressure measurement structure design, taking into account the model quality, stiffness, shape and test function.
The composite-material wing pressure-measurement model is used to simulate the aerodynamic shape and certain structural characteristics of a real wing, thereby obtaining surface pressure distributions, aerodynamic loads, and flow-field data. Compared with all-metal designs, composite materials allow for the adjustment of mass and stiffness through material selection and ply‑layup design, making them more suitable for lightweight, slender structural components and aeroelasticity studies.
The model body can be made of carbon fiber composite material and combined with the metal root connection, the mounting shaft and the internal load cell structure. The manufacturing process requires co-ordination of mold, layup, curing, surface accuracy, surface quality and pipeline space.
Xi'an Xinghualang Technology Co., Ltd. provides structural design, forming and manufacturing, metal interface processing, surface treatment and installation adaptation of composite wing models according to the target airfoil, geometric dimensions, wind tunnel interface and measurement scheme.
Core technology advantage
01 Lightweight high stiffness composite structure-reduce model quality
The higher specific strength and specific stiffness of carbon fiber composites are used to reduce the weight of the model while meeting the structural stability.
The lay direction, local reinforcement and internal support can be designed according to the test objectives.
02 Stiffness and mass distribution can be designed-support similarity study
The bending and torsional stiffness and mass distribution are adjusted by the material system, the number of layers and the structural form.
It provides a more flexible model basis for the study of aeroelasticity, flutter and load response.
03 Complex surface integral forming-keep the aerodynamic surface continuous
The mold and forming process design are completed according to the wing geometry, and the leading edge, trailing edge, wing root and gradual cross-section are finely controlled.
The surface smoothness is improved by finishing and surface treatment after molding.
04 Metal interface integration-for reliable installation and load transfer
The root of the model is equipped with a special metal connection structure, which is customized according to the support method and the installation shaft.
