PROBLEM TO BE SOLVED: To enable propeller characteristics to be accurately measured in a state close to that of a real flying object even if the object is not actually flown.SOLUTION: In a propeller characteristics measuring apparatus (1) for measuring characteristics of a propeller (8), an installation base (3) for installing a motor (9) fitted with the propeller (8) is disposed via a guide mechanism (4) for so guiding the installation base (3) as to be able to move up and down but unable to rotate relative to a base plate (2) is provided on the base plate (2); further, a moving extent sensor (14) for detecting the moving extent of the propeller (8) in the rotating direction, a driving electric power sensor (22) for detecting the driving electric power supplied to the motor (9) and a floating force sensor (10) for detecting the floating force provided by the motor (9) are connected to a controller (20); and the controller (20) is thereby enabled to measure the characteristics in a state in which the propeller (8) is fitted to the motor (9).SELECTED DRAWING: Figure 1
【課題】飛行体を実際に飛行させなくても、プロペラの特性を実際の飛行体に近い状態で正確に計測すること。【解決手段】本発明では、プロペラ(8)の特性を測定するためのプロペラ特性測定装置(1)において、基台(2)に、プロペラ(8)を装着したモータ(9)を設置するための設置台(3)を、基台(2)に対して設置台(3)が昇降可能かつ回動不能にガイドするためのガイド機構(4)を介して設けるとともに、プロペラ(8)の回転方向の移動量を検出するための移動量センサ(14)と、モータ(9)に供給される駆動電力を検出するための駆動電力センサ(22)と、モータ(9)による浮上力を検出するための浮上力センサ(10)とをコントローラ(20)に接続し、コントローラ(20)でプロペラ(8)をモータ(9)に装着した状態における特性を計測可能とすることにした。【選択図】図1
