Pressure measurement model of glass fiber wing
Integration of complex surfaces and pressure measurement for efficient construction of wind tunnel test carriers
The shape, stiffness, airtightness and interface coordination of the lightweight wing model are realized by the design of glass fiber composite molding and internal pressure system.
Glass-fiber pressure-measurement wing models are widely used in studies of pressure distribution, boundary layers, and flow separation for airfoils, wings, and blades. The model must accurately replicate the aerodynamic surface while incorporating internal pressure-tapping lines, reinforcing structures, and mounting interfaces.
Glass fiber composite materials have the characteristics of flexible molding, fine surface treatment and moderate cost, suitable for large, long size and complex surface models, and can adjust the structural stiffness through beams, ribs, core materials and local paving.
Xi 'an Xinghualang Technology Co., Ltd. provides the whole process services from surface modeling, measuring point arrangement, mold manufacturing, composite molding to surface finishing, assembly and wind tunnel adaptation.
