The variation of the loading components with simulated time during the 
pitch cycle are also somewhat similar for these two configurations. The 
comparative results for Ho presented as time in seconds following the 
point YY oy=O> W>0 are as follows:

ACCELERATION 
The variation of all measured loading components with blade angular 
position for the quasi-steady simulated acceleration condition Vv=P=n=0 
(Conditions 7 through 11 in Table 3) is shown in Figures 20 and 21 for the 
hydrodynamic loads, and is shown in Figure 22 for the total (hydrodynamic, 
centrifugal, and gravitational) loads. The amplitudes and phases of the 
harmonics of these loading components are presented in Figure 23 for 
the hydrodynamic loads and in Figure 24 for the total loads. Appendix B 
presents tabulated values of the data in Figures 20 through 24. The 
values for each loading component are presented as decimal fractions of 
the time-average value of the corresponding loading component at the self 
propulsion condition (Condition 1 in Table 3). These average values for 
both hydrodynamic loads and total loads are presented in Table 8.
