Abstract:
A rotor assembly 10 having a rotor disk 12 and a plurality of outwardly extending rotor blades 16 is disclosed. Various construction details are developed to provide effective cooling to the platform sections 20 of such rotor blades. In one particular embodiment, a damper 58 engages the underside of the rotor blades 16 and a seal member 42 inwardly of the damper engages the damper to provide damping of vibrations in the rotor blades. Both the damper and the seal member are provided with cooling air holes 42, 74 to positively distribute cooling air collected inwardly of the damper and seal member and to direct the cooling air preferentially between the adjacent platform sections 20 of the rotor blades to effectively cool the rotor blades.
