  • Foreign matter diverter systems for turbofan engines
    Patent number: 5431535
    Abstract: The axial gap (30) between a turbofan section (18) in a turbofan aircraft engine (10) is enlarged so that foreign matter thrown radially outwardly by the fan blades (48) will travel vectors (52, 54) which are located forwardly of the forward boundary (28) of the splitter wall (26). This results in the foreign matter being expelled through the fan duct (14) the engine (10), preventing it from entering into the engine core (20). Forward extensions (56, 58) of the fan blades can also be used for shifting the vectors (52, 54) forwardly. Smaller forward extensions (56, 58) can be used in combination with a partially widened gap (30) for positioning the vectors (52, 54) forwardly of the splitter wall forward boundary (28).
