The invention relates to a gas turbine engine and a method for cooling said gas turbine engine. The gas turbine engine (1) comprises a compressor (2), a combustor plenum (3) housing at least one combustion chamber (4), at least one turbine (5) having at least a first stage (16). The turbine (5) comprises an outer housing (7) and a turbine vane carrier (12). A cooling plenum (13) for air is definedbetween the outer housing (7) and the turbine vane carrier (12). The gas turbine engine (1) comprises an annular element (15, 19) upstream of a vane (10A) of the first stage with respect to the hot gas direction (G), and a heat exchanger (6) is connected between the combustor plenum (3) and the cooling plenum (13). 本发明涉及燃气涡轮发动机及用于冷却所述燃气涡轮发动机的方法。具体而言，燃气涡轮发动机(1)包括压缩机(2)、收纳至少个燃烧室(4)的燃烧器仓室(3)、具有至少第级(16)的至少个涡轮(5)。涡轮(5)包括外壳(7)和涡轮导叶载体(12)。用于空气的冷却仓室(13)限定在外壳(7)与涡轮导叶载体(12)之间。燃气涡轮发动机(1)包括相对于热气体方向(G)在第级的导叶(10A)上游的环形元件(15,19)，和在燃烧器仓室(3)与冷却仓室(13)之间液压连接的热交换器(6)。
