摘要： A method and apparatus for testing an engine component, e.g. a turbine blade, guide vane or exhaust duct, for blockage of one or more through-holes (114) in at least a portion of a wall (104) thereof, wherein the portion of the wall (104) comprises a known pattern of through-holes (114) therein extending between first and second sides of the wall (104), the method comprising:
(i) providing in a first region to the first side of the wall (104) a supply (130) of a test fluid, wherein the test fluid comprises a material able to scatter electromagnetic radiation incident thereon;
(ii) causing or permitting a flow of the test fluid to occur from the first region to a second region to the second side of the wall (104);
(iii) illuminating the second region with electromagnetic radiation (155) to cause scattering of electromagnetic radiation by material (160) exiting substantially non-blocked through-holes (114) in the wall portion (104) having passed therethrough from the first side to the second side;
(iv) detecting said scattering of electromagnetic radiation from said substantially non-blocked through-holes (114); and
(v) comparing said detected scattering of electromagnetic radiation from said substantially non-blocked holes (114) with the known pattern of through-holes in the component wall portion (104) to determine the presence and/or location and/or identity of any blocked or partially blocked through-holes (114B) in the component wall portion (104).
