lar application. A distinct advantage of film cooling for practical appli- 

 cations is that it can be very easily adapted in most designs. In addition, 

 film cooling, as explained above, appears to be a good method for thor- 

 oughly cooling a specific location. In this connection, further intensive 

 research on the problems of methods of injection, stability of coolant film.
