An airfoil (1) having one-sided pedestals (131) is disclosed. The airfoil (1) defines various cavities, such as an inflow feed cavity (110), an impingement cavity (130), and an outflow cavity. The various cavities are connected by crossover sections (120, 140) such as an inflow crossover section (120) and an outflow crossover section (140). Cooling air is conducted into the inflow feed cavity (110) and then out of the inflow feed cavity (110) through an inflow crossover section (120) into an impingement cavity (130), and through an impingement cavity (130). The cooling air may be conducted out of the impingement cavity (130) and into an outflow cavity through an outflow crossover section (140). Various cavities include one-wall pedestals (131). One-wall pedestals (131) are structures extending from a wall of a cavity into the void of the cavity, whereupon cooling air may impinge, effectuating convective cooling. A corresponding method of making such an airfoil is also provided. |
