Abstract:
A method for providing enhanced efficiency in a turbine engine having compression, heat addition, and expansion stages, said method comprising:providing a rotor having blades capable of containing fluid therebetween;providing at least one stator adjacent to said rotor and having a plurality of chambers for receiving fluid therein with said chambers effectively progressively varying in size with respect to the direction of rotation of said rotor; andproviding a fluid flow path through at least the compression and heat addition stages and having a pressure difference existing during normal operation between the compression and heat addition stages, with fluid in said fluid flow path extending between said at least one stator and said rotor, and with fluid in said fluid flow path at said rotor contained between said blades of said rotor being transferred between the compression and heat addition stages and encountering said plurality of chambers in said at least one stator upon rotation of said rotor.
