transonic airfoil shock wave has been reduced

摘要

PROBLEM TO BE SOLVED: To provide a transonic turbine blade 60.;SOLUTION: Expansion waves 125 are generated on a lifting surface 52 on the blade 60. The expansion waves 125 extend downstream through the shock waves 115 generated at the trailing edges 78 of an adjacent blade 60. In the present invention, the strength of the shock waves 115 is increased to attenuate the expansion waves 125 that pass through the shock waves 115. One stratagem for increasing the shock waves is to reduce aerodynamic load of the trailing edges 78 generating the shock waves 115.;COPYRIGHT: (C)2003,JPO
