Finally, one can observe (Fig. 41) that the values of e, which pro- 

 vide good performances, are very close (between 0.001 and 0.03). They are re- 

 markably lower than the values of a cold-air hydrojector (Fig. 42 and Refs. [7] 

 and [8]), which reach and exceed 0.01. 



(f) No remarkable results derived from the analysis of powerplants 

 where after combustion was realized. On the contrary, however, no numerical 

 analysis was developed about it. It is noteworthy to consider the possibility that
