This appendix contains plots and tables related to the minimum and maximum value of each variable versus the pitch amplitude a for the prescribed pitch motion of Model 5514 in task 1. The plots are found in Figures P-1 through P-60. For each variable, speed, and frequency there is one plot that depicts the results from all the codes. If f stands for a time-dependent variable, then the quantities plotted are the minimum and maximum of f f-fthetasub a, where f is the mean. Only filtered values f are used since filtered values lessen the impact of spikes that probably originate in numerical filtering schemes in the codes. Linear variation as a function of the amplitude appears as a horizontal line. Quadratic variation appears as a straight line with a nonzero slope. Tables P-1 through P-480 in this appendix correspond to the plots. Following each plot is one table for each of the eight codes for which data were received. The tables give information about the mean, the minimum and maximum of the unfiltered variable, the minimum and maximum of the filtered variable, and the starred function depicted in the figure. For the corresponding time history plots, the reader is referred to Appendix F.
