APPENDIX A 
DETAILS OF WAKES* 
Tables 9 and 10 present the velocity component ratios and the 
harmonic content of the wakes in the plane of the propeller, both with 
and without the downstream dynamometer boat. The data at even radial sta- 
tions were obtained by interpolation and extrapolation of the measured 
data as described in-Reference 38. 
*Al11 data presented in Appendix A were obtained from wake surveys con- 
ducted by R.F. Roddy, DINSRDC Code 1524. Further details of these wake 
surveys will be presented in a future DINSRDC report.
