A turbine blade for a turbine engine having an internal cooling system formed from at least one cavity for receiving cooling air from a turbine blade assembly, passing the cooling air through the internal cooling system, and expelling the cooling air through orifices in a leading edge forming a showerhead, orifices in a trailing edge and in other locations. The showerhead includes exhaust orifices extending at various angles relative to each other through an outer wall forming the turbine blade. The exhaust orifices may form rows of orifices that are offset generally orthogonally and generally parallel to a longitudinal axis of the blade. The exhaust orifices are configured to effectively cool the leading edge portion of the blade and to reduce the likelihood of cracking of the outer wall forming the leading edge.
