Abstract:
A fan section for a gas turbine engine includes a fan blade having an airfoil with an exterior surface. A platform seal is adhered to the airfoil. A fan section for a gas turbine engine includes a fan hub having a slot. A fan blade includes an airfoil extending from a root to a tip. The root is received in the slot. A platform is secured to the fan hub and is arranged between adjacent fan blades. A seal has a base secured to opposing sides of the fan blade and a flap integral with and extending from the base portion and canted toward the root and engaging the platform to provide a sealed inner flow path.
Abstract:
The present disclosure relates generally to the field of fan blade platforms for gas turbine engines. More specifically, the present disclosure relates to a compressed chopped fiber fan blade platform for a gas turbine engine.
Abstract:
A platform (410) for an airfoil in a gas turbine engine is provided. The platform includes a top wall (411) configured to connect to an airfoil of the gas turbine engine, a connector (422) configured to receive a pin and secure the platform to a rotor of the gas turbine engine, and a sidewall (434) extending from the top wall to the connector, the sidewall having a first arm (434a) and a second arm (434b), wherein the first arm and the second arm are curved such at a bowed sidewall extends from the top wall to the connector.
Abstract:
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.

Abstract:
A platform (410) for an airfoil in a gas turbine engine is provided. The platform includes a top wall (411) configured to connect to an airfoil of the gas turbine engine, two sidewalls (432) extending downward from the top wall, a connector (422) attached to and connecting the two sidewalls, wherein the top wall, the sidewalls, and the connector define an interior volume of the platform, and a single stiffener (436) extending from the connector to the top wall within the interior volume between the two sidewalls. The connector defines two parallel apertures (426a; 426b) passing through the connector.
Abstract:
A fan blade platform (150) is provided. The fan blade platform (150) may include a flowpath (106), a first sidewall (110; 152) extending from the flowpath (106) to a circular member (164), and a second sidewall (112; 154) extending from the flowpath (106) to the circular member (164). A stiffening member (158) may also extend from the circular member (164) to the flowpath (106) and be formed integrally with the first sidewall (110; 152), the second sidewall (112; 154), and the flowpath (106).
