    摘要: A gas turbine engine (10) having a pressure-rise combustor (30) and the pressure-rise combustor (30) is positioned upstream of a stage of turbine nozzle guide vanes (32). The vanes (33) of the stage of turbine nozzle guide vanes (32) forms an ejector and each of the vanes (33) has an upstream portion (34) and a downstream portion (36). The upstream portions (34) of the vanes (33) have leading edges (38) and the upstream portions (34) are arranged substantially straight and parallel to define constant area mixing passages (40) for a flow of gases there-through. The downstream portions (36) of the vanes (33) are arranged at an angle to the upstream portions (34) of the vanes (33) to turn the flow of gases there-through.

    摘要: A pressure rise combustor is provided with fuel provided at intermittent periods. The fuel is pulsed at timings such that the phase lag between the addition of the fuel and a resultant pressure rise is minimised. The fuel is pulsed such that the unsteady addition of heat reinforces the amplitude of an unsteady pressure fluctuation.

    摘要: A gas turbine engine (10) comprising a compressor (14), a turbine (16) a combustor (20) and a recuperator (26), a first portion air (22) from the compressor (20) is ducted into the combustor (20) where it mixes with fuel and is burned, a second portion (24) of compressor air passes through a high-pressure side of the recuperator (26) where it is heated by gas (32) ducted from the turbine (16), the second portion of air (24) flowing through the recuperator (26) is mixed with the first portion of gas (22) to form a third gas flow (30) which is ducted into the turbine (16).
