 IR-(l) powerplant (y - 0.9, (3 = 12, a. p.) 



the heating of the gas in the IR FC powerplant (but the same thing can be 

 realized for any hot- gas powerplant) could be partially supplied by the turbine 

 exhaust in a heat recuperator. This practice would not provide any thrust im- 

 provement, but it would surely improve the efficiency.
