A continuous flow structural health monitoring system for detecting a crack in a component or structure comprises a pressure source, a fluidic circuit and a measurement system. The pressure source supplies fluid at a regulated pressure relative to ambient pressure. The fluidic circuit couples at one end to the pressure source and opens at an opposite end to ambient pressure. The pressure source produces a substantially constant and continuous flow of fluid through the fluidic circuit. The fluidic circuit has a first passage having a first surface portion of the component or structure. The measurement system monitors perturbations in the flow of fluid through the first passage to provide an indication of structural health of the component or structure. |
