As many aerospace ducting manufacturers will tell you, ducting is a major component of any helicopter and airplane design. Ducting is so important in aerospace that it is responsible for distributing various fluids and air throughout the entire aircraft.
Ducting is responsible for temperature regulation, fuel distribution, ventilation, anti-icing, humidity control, and so much more. The failure of any of these systems can have fatal consequences.
High-Pressure Ducts in Aerospace
In aerospace applications, a high-pressure duct is used in both helicopters and airplanes for various applications. Regardless of how the high-pressure duct is being used, it is manufactured using materials that have the ability to withstand high pressures, chemical exposures, and high temperatures. The typical materials used in high-pressure duct systems include Kevlar, carbon fiber, stainless steel, and aluminum.
The most common location of a high-pressure duct system in airplanes and helicopters is running from the engine to the edges of the wings. The duct system passes through the fuselage to reach each location. Applications in aerospace using high-pressure duct systems include environmental control systems, engine starter, air intake-exhaust, anti-ice systems, and more.
Low-Pressure Ducts in Aerospace
Aerospace ducting manufacturers use low-pressure ducts for a handful of applications. These low-pressure duct systems can only be used in low-temperature and low-pressure areas.
In aerospace manufacturing, you most often see low-pressure duct systems used in the cabin for the air conditioning supply, to cool the instruments, defogging, and other low-pressure ventilation areas. The most low-pressure duct is made from aluminum or a composite.
