Abstract: The disclosed concept presents a combination of a gas-turbine power-plant and a pneumatic motor, acting as an isobaric motor-combustor for the gas-turbine power-plant, to the end of achievement of a highly efficient generation of energy/power. In the process of isobaric combustion of fuel within the pneumatic motor, the pneumatic motor, which is supplied with compressed air by an air compressor from the gas-turbine power-plant, simultaneously performs mechanical work of isobaric combustion (in addition to the mechanical work of adiabatic expansion of the gas turbine) and thus increases the overall cycle output and the cycle thermal efficiency. Various combinations between gas-turbine power-plant and pneumatic motor are disclosed: simple, simple-recuperated, intercooled and intercooled-recuperated gas-turbine-cycle configurations, as well as simple and intercooled combined gas-turbine-steam-turbine cycle configurations.

Abstract: 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.
