Describes the design development of the ventilating and air handling systems in a corrosion-control facility for large aircraft. It is based on the findings of a study conducted for the US Air Force to determine the most cost-effective method for performing corrosion control processes on large aircraft. States the research team was a multi-disciplinary group with expertise in architecture, spray painting, industrial hygiene, fire protection and industrial ventilation.KEYWORDS: Ventilation, air, recirculating, designing, corrosion protection, aircraft.
