Customized wind tunnel experimental model
From the real object to the experimental scale, the precise construction of the aerodynamic research carrier.
Based on similarity theory, complex form factor manufacturing and test interface integration, it provides customized wind tunnel models for aircraft, vehicles, buildings and energy equipment.
A wind-tunnel model is a high-precision test specimen that, based on similarity theory, simulates the aerodynamic characteristics of a real object in a laboratory setting, and is used to obtain data on lift, drag, moments, pressure distribution, stability, and the flow field. The model must not only replicate the external shape but also be compatible with the wind tunnel’s support, force-measurement, pressure-measurement, and flow visualization systems.
Different research objects have obvious differences in size, material, stiffness, surface quality and measurement function. Aircraft, helicopters, airships, vehicles, buildings, cooling towers and special configurations require different scaling strategies, internal structures and manufacturing processes.
Xi'an Xinghualang Technology Co., Ltd. carries out the system design of model scheme, structure, material, processing, surface treatment and on-site interface according to the three-dimensional data, drawings or concept scheme provided by customers, and provides customized services from single component to complete machine model.
