An analysis was made of the hinge-moment effectiveness of tabs based on the available two- and three-dimensional tab data. The results of the analysis indicated that the effects of tabs on control-surface hinge moments can be estimated from geometric characteristics of the tab-flap-airfoil combination with a reasonable degree of accuracy.

Various wind-tunnel data on the hinge-moment characteristics of control-surface tabs have been collected and analyzed. The data, all of which are for plain unbalanced tabs, were obtained from force tests of models in two- and three-dimensional flow and from pressure-distribution measurements on models in two-dimensional flow. Some data that show the effects of Mach number on tab hinge moments for representative conventional and NACA 6-series airfoil sections are presented.

Flight Testing, Volume II: Stability and Control focuses on the development of adequate flight test techniques for the appraisal of stability and control characteristics and flying qualities of airplanes. This book discusses the flying quality requirements, longitudinal motions, and flight determination of stick-fixed neutral points. The determination of aerodynamic parameters from steady maneuvering, desirable control characteristics in steady flight, and various forms of lateral control surfaces are also elaborated. This publication likewise covers the measurement of maximum lift coefficient, emergency anti-spin devices, and concept of the altitude-Mach number flight envelope. This volume is recommended for design, development or research engineers, test pilots, and instrumentation personnel interested in airplane stability and control.
