FAN BLADES FOR GAS TURBINE ENGINES WITH REDUCED STRESS CONCENTRATION AT LEADING EDGEA light weight fan blade for a gas turbine engine is disclosed. The disclosed fan blade has an increased chord length at a transition section between the inner edge or single tooth attachment portion of the fan ...
For many years, fan blades for high bypass aero-engines were manufactured from solid titanium alloy forgings and were designed with mid-pan snubbers to control vibration. However, snubbers impeded airflow and reduced aerodynamic efficiency, yielding to high fuel consumption. Modern fan blade designs...
A fan blade for a gas-turbine engine which comprises a supporting structure (2) in fiber-composite material is enclosed by a sheet-metal enveloping structure (4) only in an area of the airfoil (3) such that the loads and stresses acting on the blade root (11), as well as the risk ...
