Abstract
A system and method for reducing blade strain on the fan blades of an air cycle machine is proposed. The method involves a strut arrangement that is positioned in a cylindrical air passage upstream from the fan assembly. The strut arrangement includes at least three struts, wherein the at least three struts are separated by unequal degrees of separation along the circumference of the air passage. The strut arrangement effectively reduces the strain on the blades of the fan assembly.
