摘要： A gas turbine engine has a fan rotor, a first compressor rotor and a second compressor rotor. The second compressor rotor compresses air to a higher pressure than the first compressor rotor. A first turbine rotor drives the second compressor rotor and a second turbine rotor. The second turbine drives the compressor rotor. A fan drive turbine is positioned downstream of the second turbine rotor. The fan drive turbine drives the fan through a gear reduction. The first compressor rotor and second turbine rotor rotate as an intermediate speed spool. The second compressor rotor and first turbine rotor together as a high speed spool. The high speed spool and the fan drive turbine configured to rotate in the same first direction. The intermediate speed spool rotates in an opposed, second direction.

摘要： A gas turbine engine with a compressor rotor having compressor impulse blades that delivers gas at supersonic conditions to a stator. The stator includes a one or more aerodynamic ducts that each have a converging portion and a diverging portion for deceleration of the selected gas to subsonic conditions and to deliver a high pressure oxidant containing gas to flameholders. The flameholders may be provided as trapped vortex combustors, for combustion of a fuel to produce hot pressurized combustion gases. The hot pressurized combustion gases are choked before passing out of an aerodynamic duct to a turbine. Work is recovered in a turbine by expanding the combustion gases through impulse blades. By balancing the axial loading on compressor impulse blades and turbine impulse blades, asymmetrical thrust is minimized or avoided.

摘要： An apparatus and method for recycling or maintaining the latent heat of vaporization in work producing cycles such as the Rankine cycle by eliminating phase changes by replacing the condenser in such cycles with a compressor and restricting or limiting the expansion to reduce compressor work requirements.The standard compound turbine prevalent today consisting of a single Curtis stage in tandem with pressure compounded stages has been replaced with several two-row Curtis stages.An alternative embodiment utilizes one or several two-row Curtis stages and a condenser as in the Rankine cycle but limits the expansion, maintaining a relatively high pressure typical in exhaust from this type of turbines. The high pressure maintains the temperature of the condensate sufficiently high to eliminate feed water preheating.Sacrifice of low pressure output is compensated in both cases by salvaging latent heat of vaporization which would not be possible economically, if expansion carried to the maximum. Sufficient heat is added in the boiler to restore the vapor to its operating condition and to replace any excess heat removed at the final stage of the turbine.
摘要翻译：一种用于在诸如朗金循环的工作生产循环中循环或维持蒸发潜热的装置和方法，通过用压缩机替代这种循环中的冷凝器并消除相变，并限制或限制膨胀以减少压缩机工作要求。目前由标准复合涡轮机组成的单一柯蒂斯级与压力复合级组合在一起，已被几排两排柯蒂斯级替代。一个替代实施例在兰金循环中使用一个或几个两排Curtis级和一个冷凝器，但是限制了膨胀，保持了来自这种类型的涡轮机的典型排气中相当高的压力。高压保持冷凝水的温度足够高以消除给水预热。在两种情况下，通过消除蒸发潜热而牺牲低压输出，这在经济上是不可能的，如果膨胀达到最大值。在锅炉中加入足够的热量以将蒸汽还原到其运行状态并替换在涡轮机的最后阶段除去的任何多余的热量。
