EXPERIMENTAL INVESTIGATION OF THE FORCES AND MOMENTS DUE TO SIDESLIP OF A SERIES OF TRIANGULAR VERTICAL-AND HORIZONTAL-TAIL COMBINATIONS AT MACH NUMBERS OF 1.62, 1.93, AND 2.41

摘要

An experimental investigation was made at Mach numbers of 1.62, 1.93> and 2.41 of a series of tail combinations consisting of a triangular ver¬tical tail attached symmetrically to a triangular horizontal tail to determine the lateral force, yawing moment, and rolling moment due to sideslip. The apex angles of both the vertical- and horizontal-tail sur-faces were varied systematically in order to obtain results for an appre-ciable range of operating conditions.nThe results of the investigation indicated that, for tails having subsonic leading edges and supersonic trailing edges, the lateral-force derivative and the yawing-moment derivative were predicted satisfacto¬rily by the method presented in NACA TN 5071 except when the leading edges approach a sonic condition.
