Sliding-blade rotary air-heat engine with isothermal compression of air

A rotary air-heat engine utilizing isothermal compression of air comprising:

• a rotary air-water compressor having a rotor, an ambient air intake, water atomizer injectors, and an air-water mixture discharge port;
• an air-water separator having an inlet connected with said air-water compressor air-water mixture discharge port, a water outlet, and an air outlet;
• a heat exchanger having an air inlet connected with said air-water separator air outlet, a working fluid inlet, an exhaust port, and a preheated air outlet;
• a combustion chamber having a preheated air inlet connected with said heat exchanger preheated air outlet and a high temperature working fluid discharge port;
• a rotary gas expander having a rotor operatively connected with said rotary air-water compressor rotor for rotating said air-water compressor rotor, a working fluid inlet connected with said combustion chamber working fluid discharge port, a working fluid outlet connected with said heat exchanger working fluid inlet, and a water cooling system including a water inlet connected with said air-water separator water outlet and a water outlet;
• power take-off means connected with at least one of said rotors;
• and
• a water condenser having an inlet connected with said gas expander water cooling system water outlet, and an outlet connected with said air-water compressor water atomizer injectors;
• wherein
• ambient air is drawn into said air-water compressor upon rotation of its said rotor and atomized water is introduced into said air-water compressor through said water atomizer injectors to form an ambient air-water mixture therein and upon continued rotation of said rotor, said ambient air-water mixture is isothermally compressed and the compressed air-water mixture is discharged into said air-water separator where water is separated from said isothermally compressed air-water mixture and discharged into said gas expander water cooling system and air separated from said air-water mixture is discharged into said heat exchanger, preheated therein, and discharged into said combustion chamber and the products of combustion are discharged into said rotary gas expander as a working fluid, adiabatically expanded therein to rotate its said rotor, said air-water compressor rotor and said power take-off means and thereby produce useful work, and spent working fluid is discharged from said rotary gas expander into said heat exchanger and used as waste heat to preheat air passing therethrough.
