1. A system for a gas turbine engine, comprising:
a flowpath wall comprising a surface and an opening to a blind aperture, the surface forming a peripheral boundary of an internal engine flowpath, the opening disposed in the surface, the opening having a lateral opening width, and the blind aperture extending vertically into the flowpath wall from the opening; and
a deflector projecting vertically out from the flowpath wall into the internal engine flowpath, the deflector configured to deflect gas flowing within the internal engine flowpath over the opening, the deflector having a lateral deflector width which extends laterally from a first side of the deflector to a second side of the deflector, the lateral deflector width equal to or greater than the lateral opening width, the deflector vertically tapering to the surface as the deflector extends laterally from a peak of the deflector to the first side of the deflector, and the deflector vertically tapering to the surface as the deflector extends laterally from the peak of the deflector to the second side of the deflector.
