Each stage of this path serves a specific function and relies on key system components: <\/p><h3>Settling and flow conditioning chamber (honeycomb \/ screens)<\/h3><p>The airflow enters the settling chamber, where it passes through flow-straightening screens and honeycomb structures. Their function is to eliminate swirl, vortices, and residual turbulence generated by the fan, ensuring a uniform and well-aligned flow before acceleration. <\/p><h3>Contraction chamber (flow acceleration)<\/h3><p>The air passes through a converging nozzle that reduces the flow cross-sectional area and, therefore, increases the flow velocity in a controlled manner. At this stage, the principles of Bernoulli and flow continuity are directly applied to obtain a clean, accelerated stream that impinges on the model in a repeatable way. <\/p><h3>Test section (testing area)<\/h3><p>It is the core of the wind tunnel. This is where the model to be studied is installed. The flow interacts directly with the object while sensors and data acquisition systems record parameters such as drag and lift forces, pressure distribution, or flow visualization. The walls are typically transparent to facilitate observation and optical analysis.   <\/p><h3>Diffuser (pressure recovery)<\/h3><p>After passing the model, the air enters the diffuser, a divergent section that reduces flow velocity and recovers static pressure. This process improves the energy efficiency of the system and helps stabilize the flow before the next cycle. <\/p><h3>Power and return system (fans and recirculation)<\/h3><p>The fan is the driving element of the wind tunnel, providing the energy required to move the air at a constant rate. In closed-circuit tunnels, the flow is not exhausted after the diffuser but instead redirected through a return system with curved guide vanes that preserve flow quality. This configuration enables energy savings and helps maintain stable and repeatable conditions.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-aef4360 elementor-widget elementor-widget-image\" data-id=\"aef4360\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1024\" height=\"586\" src=\"https:\/\/ftmtechnologies.com\/wp-content\/uploads\/2026\/01\/componentes-de-un-tunel-de-viento-1024x586.jpg\" class=\"attachment-large size-large wp-image-2105\" alt=\"partes de un tunel de viento\" srcset=\"https:\/\/ftmtechnologies.com\/wp-content\/uploads\/2026\/01\/componentes-de-un-tunel-de-viento-1024x586.jpg 1024w, https:\/\/ftmtechnologies.com\/wp-content\/uploads\/2026\/01\/componentes-de-un-tunel-de-viento-300x172.jpg 300w, https:\/\/ftmtechnologies.com\/wp-content\/uploads\/2026\/01\/componentes-de-un-tunel-de-viento-768x440.jpg 768w, https:\/\/ftmtechnologies.com\/wp-content\/uploads\/2026\/01\/componentes-de-un-tunel-de-viento.jpg 1100w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3e1a9ad elementor-widget elementor-widget-spacer\" data-id=\"3e1a9ad\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dad43fe elementor-widget elementor-widget-heading\" data-id=\"dad43fe\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What happens during a wind tunnel test<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-66439e2 elementor-widget elementor-widget-text-editor\" data-id=\"66439e2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p data-pm-slice=\"1 1 []\">An aerodynamic test is a carefully designed process that is carried out through several technical and sequential stages:<\/p>\n<ul data-spread=\"false\" data-pm-slice=\"3 3 []\">\n<li>\n<p><strong>Model installation<\/strong> and sensor calibration<\/p>\n<\/li>\n<li>\n<p>Flow stabilization until the desired conditions are reached<\/p>\n<\/li>\n<li>\n<p><strong>Data acquisition<\/strong> through sensors and flow visualization systems<\/p>\n<\/li>\n<li>\n<p><strong>Real-time or post-test<\/strong> analysis of the measured variables<\/p>\n<\/li>\n<\/ul>\n<p data-pm-slice=\"1 1 []\">Throughout the entire process, the objective is to reproduce conditions that are as realistic as possible within a controlled laboratory environment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1880fa3 elementor-widget elementor-widget-heading\" data-id=\"1880fa3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Types of tests performed in a wind tunnel<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9be19df elementor-widget elementor-widget-text-editor\" data-id=\"9be19df\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"186\" data-end=\"633\">Wind tunnel testing does not always involve the same types of experiments, as each test is designed to address specific measurement or validation objectives.
