A rotor blade system comprising:
- a rotor;
- and
- a plurality of blades coupled to the rotor, the plurality of blades arranged in an airfoil distribution pattern, the airfoil distribution pattern comprising one or more baseline blades including a first sheath having a first chord length and a first thickness and one or more intentionally mistuned blades including a second sheath having a second chord length and a second thickness, the one or more intentionally mistuned blades including an intentional mistuning feature that includes at least one of a varied second chord length of the second sheath relative to the first chord length of the first sheath or a varied second thickness of the second sheath relative to the first thickness of the first sheath.
A turbine engine comprising:
- a fan section;
- a compressor section;
- and
- a turbine section, wherein at least one of the fan section, the compressor section, and the turbine section includes a rotor blade system comprising:
- a rotor;
- and
- a plurality of blades coupled to the rotor, the plurality of blades arranged in an airfoil distribution pattern, the airfoil distribution pattern comprising one or more baseline blades including a first sheath having a first chord length and a first thickness and one or more intentionally mistuned blades including a second sheath having a second chord length and a second thickness, the one or more intentionally mistuned blades including an intentional mistuning feature that includes at least one of a varied second chord length of the second sheath relative to the first chord length of the first sheath or a varied second thickness of the second sheath relative to the first thickness of the first sheath.
