Abstract
A combustor of a turbine engine combusts fuel and air. The combustor includes a dome and a heat shield fastened to the dome. The heat shield is unconstrained relative to dome, to permit relative thermal expansion and contraction in a radial direction. A heat shield inner portion is generally annular in shape, is arranged about a dome eyelet longitudinal centerline axis, is smaller in diameter than a dome inner portion, and is assembled inside of the dome inner portion. A plurality of pinned assemblies fastens the heat shield to dome. Each pinned assembly includes a fastener with a pin end, the pin end assembled in a clearance fit into a hole in the heat shield inner portion. The fastener is fixed to the dome inner portion, the pin end sliding in the hole in the heat shield during relative thermal expansion and contraction between the dome and the heat shield.
