FIN LOADS AND TIP-CONTROL HINGE MOMENTS ON A l/3-SCALE MODEL SIMULATING THE FIRST STAGE OF THE SCOUT RESEARCH VEHICLE AT A MACH NUMBER OF 2.01 By Ross B. Robinson and Emma Jean Landrum

摘要

An investigation has been conducted at a Mach number of 2.01 in the Langley 4- by 4-foot supersonic pressure tunnel to determine the fin loads and tip-control hinge moments on a l/8-scale model simulating" the first stage of the Scout research vehicle. The model was a body of revolution with cruciform, 45° delta tail fins,nFor the range of this investigation, hinge moment was small and varied nonlinearly with control-deflection. Roll angle had no effect on the control-effectiveness parameters which were relatively constant throughout the angle-of-attack range.
