The air distribution system must maintain the required air velocity and environmental conditions around a large and aerodynamically complex aircraft while supporting the controlled transport of&nbsp;<strong>paint overspray, solvent vapours and volatile organic compounds (VOCs)<\/strong>&nbsp;toward the extraction system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, ventilation is considered an integral part of the aircraft painting process rather than simply a building HVAC function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gerhman, in cooperation with its strategic partner&nbsp;<strong>Lindab<\/strong>&nbsp;and in coordination with mechanical subcontractor&nbsp;<strong>Birle\u015fim M\u00fchendislik<\/strong>, developed the air distribution solution from the engineering design stage through&nbsp;<strong>product selection, system calculations, CFD analysis, airflow optimization and commissioning<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The air distribution system was implemented using&nbsp;<strong>Lindab RCW low-turbulence displacement diffusers<\/strong>, selected and configured according to the specific aerodynamic and operational requirements of the aircraft paint hangar.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Engineering Challenge<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aircraft refinishing consists of several different processes:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Paint Stripping \u2192 Cleaning \u2192 Surface Preparation \u2192 Priming \u2192 Final Painting<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These operations do not necessarily require identical ventilation conditions. Required surface velocities, contaminant loads and active working zones vary throughout the painting process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aircraft geometry creates an additional engineering challenge. The&nbsp;<strong>fuselage, wings, engines, horizontal stabilizers and vertical tail<\/strong>&nbsp;act as large aerodynamic obstructions within the hangar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Their interaction with the supply airflow can create:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Low-velocity regions \u00b7 Aerodynamic shadow zones \u00b7 Local recirculation \u00b7 Non-uniform surface velocities<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simply increasing the total ventilation rate does not necessarily eliminate these conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The engineering objective was therefore to establish the&nbsp;<strong>required airflow velocity and direction around the active aircraft surfaces<\/strong>, while minimizing unnecessary airflow to areas where no active process was taking place.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Engineering Design &amp; Product Selection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Gerhman developed the system using its&nbsp;<strong>engineering calculation and product-selection software<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The design process evaluated the main aerodynamic and thermal parameters affecting air distribution:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Airflow Rate \u00b7 Surface Air Velocity \u00b7 Discharge Velocity \u00b7 Pressure Drop \u00b7 Throw Distance \u00b7 Jet Penetration Depth \u00b7 Discharge Direction \u00b7 Supply-Air Temperature \u00b7 Operating Zone<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Different operating scenarios were evaluated according to the individual stages of the aircraft painting process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach allowed the air distribution system to be designed according to the actual process requirements rather than sizing the complete hangar around a single maximum operating condition.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">CFD-Based Airflow Analysis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Following the preliminary engineering calculations,&nbsp;<strong>Computational Fluid Dynamics (CFD)<\/strong>&nbsp;analysis was used to evaluate and optimize the proposed airflow concept before implementation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CFD studies analysed the interaction between:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Supply Airflow + Lindab RCW Diffusers + Aircraft Geometry + Process Zones + Extraction System<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The simulations were used to evaluate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>air velocity distribution around the aircraft,<\/li>\n\n\n\n<li>surface airflow uniformity,<\/li>\n\n\n\n<li>airflow direction and jet penetration,<\/li>\n\n\n\n<li>potential low-velocity and recirculation zones,<\/li>\n\n\n\n<li>airflow behaviour around the fuselage, wings and tail,<\/li>\n\n\n\n<li>interaction between supply and extraction,<\/li>\n\n\n\n<li>alternative zonal operating scenarios.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">CFD therefore served as an&nbsp;<strong>engineering design and verification tool<\/strong>, allowing alternative configurations to be analysed before the final system was implemented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This was particularly important because conventional air-change calculations and catalogue-based diffuser selections alone cannot fully represent the complex three-dimensional airflow patterns created around an aircraft.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Air Distribution Product: Lindab RCW<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The final air distribution solution was implemented using&nbsp;<strong>Lindab RCW low-turbulence displacement diffusers<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The RCW units were selected for their ability to provide the aerodynamic characteristics required by the aircraft painting process:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Low-Turbulence Displacement Airflow<\/strong><br><strong>Adjustable Air Discharge Direction<\/strong><br><strong>Electrically Controlled Jet Penetration Depth<\/strong><br><strong>Low Pressure Drop<\/strong><br><strong>Stable Operation Under Heating and Cooling Conditions<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These characteristics allowed the air distribution pattern to be adapted according to the&nbsp;<strong>aircraft geometry, active process zone and required surface air velocity<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Low-Turbulence Air Distribution<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive turbulent mixing is undesirable in aircraft painting applications because it can redistribute overspray and airborne contaminants and generate local recirculation around aircraft surfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lindab RCW units introduce conditioned air using a&nbsp;<strong>low-turbulence displacement principle<\/strong>, creating a controlled airflow field through the active working zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The design supports a defined airflow path from the supply side, across the working area and toward the extraction system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The engineering objective is therefore not only to provide the required total airflow, but also to establish the correct&nbsp;<strong>velocity distribution and airflow direction at the aircraft surface<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This supports the controlled transport of overspray, solvent vapours and VOCs toward the extraction system while limiting unnecessary dispersion within the hangar.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Adjustable Air Direction &amp; Jet Penetration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Different parts of an aircraft require different airflow trajectories and penetration distances.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The airflow requirement around the fuselage, for example, is different from that around the wings, tail section or lower aircraft surfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lindab RCW units incorporate an&nbsp;<strong>electric actuator for adjustment of the discharge characteristics and jet penetration depth<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows the airflow pattern to be adapted according to the active working zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Where greater penetration is required, the discharge characteristics can be adjusted accordingly. Where the active process is closer to the supply zone, unnecessary penetration can be reduced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This capability was an important element in developing the process-based zonal ventilation strategy.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Process-Based Zonal Control<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The main system optimization was achieved by replacing the initial&nbsp;<strong>full-volume ventilation concept<\/strong>&nbsp;with process-based zoning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of treating the entire hangar as a single ventilation zone operating continuously at peak conditions, the aircraft and surrounding working areas were divided into&nbsp;<strong>functional process zones<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system could therefore provide the required:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Airflow Rate + Surface Velocity + Airflow Direction + Jet Penetration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">according to the active aircraft zone and painting process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conditioned air was directed to where it was actually required rather than maintaining the complete hangar continuously under the maximum design condition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This engineering approach resulted in an approximately:<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">64% REDUCTION<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">IN REQUIRED AIRFLOW CAPACITY<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">compared with the initial full-volume ventilation concept.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reduction was achieved through&nbsp;<strong>better utilization and distribution of conditioned air<\/strong>, rather than by compromising the required process ventilation conditions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Contribution to Energy Efficiency<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<strong>64% figure represents a reduction in required design airflow capacity<\/strong>, not a 64% reduction in total energy consumption.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, reducing the required airflow capacity has a significant impact on the energy demand of the complete ventilation system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aircraft paint-hangar process air typically passes through several energy-intensive stages:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Filtration \u2192 Fan Transport \u2192 Heating \/ Cooling \u2192 Humidity Control \u2192 Supply \u2192 Extraction<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reducing unnecessary airflow therefore contributes to lower:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fan Energy Demand<\/strong><br><strong>Heating Load<\/strong><br><strong>Cooling Load<\/strong><br><strong>Humidification and Dehumidification Demand<\/strong><br><strong>Overall Air-Handling Requirement<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<strong>low pressure drop of the Lindab RCW diffusers<\/strong>&nbsp;provides an additional contribution by minimizing terminal pressure losses within the supply-air system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The optimized design therefore reduces the quantity of air that must be continuously transported and conditioned, making a substantial contribution to the overall&nbsp;<strong>energy efficiency and lifecycle operating cost<\/strong>&nbsp;of the facility.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Temperature &amp; Humidity Conditions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature and relative humidity are important process parameters in aircraft painting because they influence&nbsp;<strong>paint application, solvent evaporation, coating behaviour, curing and final surface quality<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lindab RCW is designed to maintain its intended air distribution characteristics with supply-to-return temperature differences of up to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cooling:<\/strong>&nbsp;\u0394T =&nbsp;<strong>\u20135 K<\/strong><br><strong>Heating:<\/strong>&nbsp;\u0394T =&nbsp;<strong>+8 K<\/strong><br><strong>Heating-Up Operation:<\/strong>&nbsp;\u0394T =&nbsp;<strong>+10 K<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature and humidity are controlled by the associated air-handling system, while the RCW units distribute the conditioned air according to the required aerodynamic conditions within the process zone.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Supply &amp; Extraction Integration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The performance of an aircraft paint-hangar ventilation system cannot be evaluated from the supply-air terminals independently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The final airflow field is determined by the interaction between:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Supply System + RCW Diffusers + Aircraft Geometry + Extraction System + Control Strategy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, the supply and extraction systems were considered as part of the same airflow concept.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective was to maintain the intended airflow path through the working zone and toward the extraction points while minimizing low-velocity and recirculation regions around the aircraft.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This system-level approach was incorporated into both the CFD analysis and the final airflow optimization.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">From Engineering Design to Commissioning<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Gerhman remained involved throughout the development and implementation of the air distribution system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The engineering workflow followed a continuous design and verification process:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Process Requirements<\/strong><br>\u2192&nbsp;<strong>Engineering Calculations &amp;

Commissioning<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This methodology was important because the actual performance of an aircraft paint hangar cannot be determined from individual diffuser catalogue data alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The complete system must be evaluated considering the interaction between the&nbsp;<strong>air distribution system, aircraft geometry, extraction arrangement and operating conditions<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Engineering Outcome<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Through the&nbsp;<strong>Gerhman\u2013Lindab cooperation<\/strong>, the initial full-volume ventilation concept was redesigned around the actual aerodynamic and process requirements of aircraft painting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gerhman\u2019s engineering calculations and product-selection tools, combined with&nbsp;<strong>CFD analysis and Lindab RCW low-turbulence displacement diffusers<\/strong>, enabled conditioned air to be directed to the required aircraft zones with controlled velocity, direction and penetration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The resulting design achieved an approximately:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">64% Reduction in Required Airflow Capacity<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">while maintaining the required process-based airflow strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reduction in conditioned-air demand also makes a significant contribution to lower&nbsp;<strong>fan, heating, cooling and humidity-control energy requirements<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project demonstrates an important principle of process ventilation engineering:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>System efficiency depends not only on the quantity of air supplied, but on how effectively that air is distributed within the required process zone.<\/strong><\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Project Highlights<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Project:<\/strong>&nbsp;Pegasus Airlines \u2013 Aircraft Maintenance &amp;
