摘要
A fan section (100) for a gas turbine engine (20) is provided. The fan section includes a fan hub including a slot and a fan blade (210) including an airfoil (211) extending from a root (143) to a tip. The airfoil has an airfoil leading edge (212) and the root is received in the slot. A first platform (134) is secured to the fan hub and arranged between adjacent fan blades. A first platform seal (300A) including a platform seal leading edge (309) and a base (306) is secured to a side of the first platform. A first winglet (304A) extends from the platform seal leading edge and contacts the airfoil leading edge. A corresponding gas turbine engine is also provided.
