Abstract
An improved turbine inlet screen for protecting the inlet to the turbine of an engine turbosupercharger and exposed to numerous substantial and rapid variations in exhaust gas temperature. The screen comprises a circular metal plate having an improved pattern of annularly arranged perforations providing radially non-linear mass relations from the plate center to its edge selected to reduce maximum thermal stresses, particularly at the plate edge, during transient gas temperature conditions.
