A gas turbine rotor blade comprising:an airfoil integrally joined with a mounting dovetail at a platform therebetween;said airfoil including opposite pressure and suction sidewalls extending chordally between opposite leading and trailing edges, and in span between a root adjoining said platform

1. A gas turbine rotor blade comprising:an airfoil integrally joined with a mounting dovetail at a platform therebetween;said airfoil including opposite pressure and suction sidewalls extending chordally between opposite leading and trailing edges, and in span between a root adjoining said platform and an opposite tip;said tip including a floor bounded by integral, first and second ribs extending upwardly therefrom along said pressure and suction sidewalls, respectively, to define an open tip plenum therebetween; andsaid first rib being inclined outwardly from said tip plenum, and having a base offset inwardly from said pressure sidewall to form an outboard ramp inclined upwardly from a bullnose at said pressure sidewall to join said first rib at a fillet and define a notch extending chordally along said first rib between said leading and trailing edges. 2. A blade according to claim 1 further comprising:a cooling circuit disposed inside said airfoil; anda row of cooling apertures extending from said circuit to said ramp between said bullnose and said fillet. 3. A blade according to claim 2 wherein said first rib bounds said tip plenum at an obtuse angle with said tip floor. 4. A blade according to claim 3 wherein said ramp is disposed higher than said tip floor. 5. A blade according to claim 4 wherein said ramp is substantially straight said fillet at said first rib to said bullnose at said pressure sidewall. 6. A blade according to claim 5 wherein said first rib overhangs said ramp and terminates in substantially vertical alignment with said pressure sidewall. 7. A blade according to claim 6 wherein said second rib bounds said tip plenum at a substantially normal angle with said tip floor. 8. A blade according to claim 7 further comprising a plurality of floor apertures extending from said cooling circuit through said tip floor to said tip plenum. 9. A blade according to claim 8 wherein said ramp has an inclination angle within the range of about 10 degrees to about 35 degrees relative to said tip floor. 10. A blade according to claim 9 wherein said first rib is inclined from said tip floor at an acute angle of about 65 degrees. 11. A gas turbine rotor blade comprising:an airfoil integrally joined with a mounting dovetail at a platform therebetween;said airfoil including opposite pressure and suction sidewalls extending chordally between opposite leading and trailing edges, and in span between a root adjoining said platform and an opposite tip;said tip including a floor bounded by integral first and second ribs extending upwardly therefrom along said pressure and suction sidewalls, respectively, to define an open tip plenum therebetween; andsaid first rib being inclined outwardly from said tip plenum, and having a offset inwardly from said pressure sidewall to form an outboard ramp extending from said pressure sidewall to said first rib and defining a substantially normal notch therebetween. 12. A blade according to claim 11 wherein said tip ramp is inclined upwardly from said pressure sidewall to join said first rib at a fillet. 13. A blade according to claim 12 wherein said first rib bounds said tip plenum at an obtuse angle with said tip floor. 14. A blade according to claim 13 wherein said second rib bounds said tip plenum at a substantially normal angle with said tip floor. 15. A blade according to claim 13 further comprising:a cooling circuit disposed inside said airfoil; anda row of cooling apertures extending from said circuit to said ramp. 16. A blade according to claim 15 wherein said ramp is disposed higher than said tip floor. 17. A blade according to claim 15 wherein said ramp is substantially straight from said fillet at said first rib to a bullnose at said pressure sidewall. 18. A blade according to claim 15 wherein said first rib overhangs said ramp and terminates in substantially vertical alignment with said pressure sidewall. 19. A blade according to claim 15 wherein said ramp has an inclination angle with in the range of about 10 degrees to about 35 degrees relative to said tip floor. 20. A blade according to claim 19 wherein said first rib is inclined from said tip floor at an acute angle of about 65 degrees.
