1. the engine component (80) for gas-turbine unit, described gas-turbine unit generates hot burning gasStream, including:

  • Substrate (82), it has in the face of the hot surface (84) of described hot burning gas stream with in the face of the cooling surface of cooling fluid stream(86), described hot burning gas stream generally limits updrift side and downstream direction relative to described hot surface (84);

    WithFenestra (90,130,160), it extends through described substrate (82) and limits centrage (102,142,172), and including;

    Metering section (98,138,168), it limits metering diameter D;

    WithDiffusion section (100,140,170), its have downstream boundary surface (110,150,180) and upstream boundary surface (108,148、

    178);

    Wherein, described diffusion section (100,140,170) as described metering section (98,138,168) downstream (106,146,176) distance along described upstream boundary surface (108,148,178) limits cover cap length and between described hot surface (84)L;

    AndWherein, 1≤

    L/D≤

    6.
