flight with a free stream temperature of 400°R and various wall-to-free 

 stream enthalpy ratios. The recovery factor when the plate is insulated 

 is plotted in Fig. F,5j. It is seen that the recovery factor follows Prl, up 

 to about Mach number 3 after which r overshoots and remains con- 

 sistently below Pr\,. Fig. F,5k gives the recovery factor for different 

 wall-to-free stream enthalpy ratios. Fig. F,51 is a cross plot of Fig. F,5k.

Fig, F,5m gives the Reynolds analogy factor for the limiting case of the 

 insulated plate, s has the same characteristics as r, overshooting Pr\ in 

 the neighborhood of M^ = 4. Fig. F,5n and F,5o gives the Reynolds 

 analogy factor for various wall-to-free stream enthalpy ratios. 



Local heat transfer coefficients, recovery factors, and Reynolds anal- 

 ogy factors for insulated flat plates in heated wind tunnels are presented 

 in Fig. F,5p, F,5q, F,5r, F,5s, F,5t, F,5u, and F,5v. In particular. Fig. 

 F,5q and F,5r show the relation of r-,^^ to Pr\ and Pr\„ and of Sins to Prl and
