—その2.フラッピング運動の測定

抄録

The motion of a stabilizer bar of the small coaxial helicopter was analyzed in the previous study. It has been made clear by the measurements on the motion of the stabilizer bar that the following two revisions are required in the analysis. (1) The motion of stabilizer bar is affected by the upper rotor. (2) Neither of the terms in the moment acting on the stabilizer bar at its hinge, k_ββ+k_ββ, can be ignored.
