<p>A transonic turbine blade (60). Expansion waves (125) are generated by a lifting surface (66) on the blade (60). The expansion waves (125) extend downstream, through a shock (115) generated at the trailing edge (78) of an adjacent blade (60). The invention increases the strength of the shock (115), thereby attenuating the expansion waves (125) passing through the shock (125). One stratagem for increasing the shock (115) is to reduce the aerodynamic load of the trailing edge (78) generating the shock (115).</p> |
