The invention described herein may be manufactured and used by or for the Government of the United States for all governmental purposes without the payment of any royalty.
An improved power plant incorporating a gas turbine and a magnetohydrodynamic (MHD) generating means is provided wherein a plurality of coolant conducting fins are disposed in the diffuser region of the duct between the MHD generator and the turbine. The cooling fins are provided with means to supply compressed coolant to the diffuser duct for mixing with the combustion gases to provide optimum gas pressure, temperature and velocity for driving the turbine.
a. means providing a source of high temperature gaseous flow;
b. a rotary turbine driven by said gaseous flow;
c. means defining a duct for conducting said gaseous flow from said source to said turbine;
d. a magnetohydrodynamic generator adjacent said duct and intermediate said source and said turbine, said generator interacting with said gaseous flow to generate electrical power; and
e. a plurality of cooling fins disposed within said duct intermediate said generator and said turbine for cooling said gaseous flow.
