<P>PROBLEM TO BE SOLVED: To provide a completely new thrust measuring method of a feed-forward type introducing thrust from input electric power, since a measuring tool and setting are costly for evaluation of a ducted fan, the evaluation can not be performed easily, only static thrust can be measured, the thrust during flying and output of the original performance of a motor are difficult to measure, performance of the ducted fan can not be correctly determined since the relation of the output to the input can not be simply recognized, and difficulty of evaluation is caused. <P>SOLUTION: The proportion of the thrust to the input electric power has been found. Since the thrust of the ducted fan has been confirmed to be in the proportional primary relation to the input electric power, the relation of input/output can be simply recognized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
