Simulation of Exposure of Aircraft Transparencies to Flight Line Environment,
Abstract
During the major portion of their lifetime, aircraft transparencies are subjected to the flight line environment. Processes initiated or aggravated by exposure to the elements usually reduce the useful life of the transparency. A procedure for developing an accelerated flight line environment test is presented. Determination of the acceleration rate of weathering simulated in the test cycle is based on the definition of a so-called worst case day for exposure to ultraviolet radiation. Acceleration rate for the simulated flight line environment test was determined by dividing the total dosage of ultraviolet radiation produced by a 'constant' laboratory source in the test environment by the total amount of ultraviolet radiation which would have been absorbed during a 'year' of worst case days. In the combined flight and flight line environment test facility, the test article was exposed to ultraviolet radiation produced by fluorescent sunlamps and black lights. A year of normal exposure to ultraviolet radiation was simulated in two months of testing.
