摘要： A novel power-producing concept is disclosed, employing a rotating-plate radial gas turbine in various gas-turbine cycle configurations. The “rotating-plate radial gas turbine” is a rotating barrel with robust rectangular plates fitted into the turbine rotor, performing the function and the role of turbine blades, contained within a motionless rigid horizontal cylinder (casing). Combustion can take place in the spaces confined between adjacent rotating plates and the static cylinder, thus enabling a practical achievement of the Atkinson cycle (constant-volume heat addition) with improved cycle thermal efficiency. Alternatively, two or more compressor stages can be combined to feed a single rotating-plate radial gas turbine in cascades, thus gradually increasing pressure of working gas within a volume bordered by adjacent un-cooled rotating plates of the radial gas turbine and the casing. Alternatively, a single compressor may be combined with one or more stages of an axial turbine for cascade feeding of a single rotating-plate radial gas turbine. This “isochoric stuffing” effect enables achievement of significantly and even drastically improved gas-turbine-cycle thermal efficiencies. Cycle heat addition may be either isobaric or isochoric in either an open-cycle or a closed-cycle configuration. Using a sufficiently efficient radial gas turbine, it is theoretically possible to obtain 100% cycle thermal efficiency in a simple radial-gas-turbine configuration with appropriately chosen compressor-stages compression pressure ratios.
摘要翻译：公开了一种新颖的发电概念，其采用各种燃气轮机循环构造中的旋转板径向燃气轮机。 “旋转板式径向燃气轮机”是具有安装在涡轮转子中的坚固矩形板的旋转筒，执行包含在不动的刚性水平圆筒（套管）内的涡轮叶片的功能和作用。燃烧可以发生在相邻旋转板和静态气缸之间的空间中，从而实现了Atkinson循环（恒定体积热量加入）的实际实现，并提高了循环热效率。或者，可以组合两个或更多个压缩机级，以级联地馈送单个旋转板径向燃气轮机，从而逐渐增加由径向燃气涡轮机和壳体的相邻未冷却的旋转板所界定的体积内的工作气体的压力。或者，单个压缩机可以与一个或多个级的轴向涡轮机组合，用于单个旋转板径向燃气涡轮机的级联输送。这种“等渗填充”效应能够实现显着甚至大幅提高的燃气轮机循环热效率。循环加热可以是开放循环还是闭环循环配置中的同量异位或等电位。使用足够有效的径向燃气轮机，理论上可以在具有适当选择的压缩机级压缩比的简单径向气体涡轮机构造中获得100％的循环热效率。
