Download Control-Surface Hinge-Moment Calculations for a High-Aspect-Ratio Supercritical Wing Book in PDF, Epub and Kindle
The hinge moments, at selected flight conditions, resulting from deflecting two trailing edge control surfaces (one inboard and one midspan) on a high aspect ratio, swept, fuel conservative wing with a supercritical airfoil are estimated. Hinge moment results obtained from procedures which employ a recently developed transonic analysis are given. In this procedure a three dimensional inviscid transonic aerodynamics computer program is combined with a two dimensional turbulent boundary layer program in order to obtain an interacted solution. These results indicate that trends of the estimated hinge moment as a function of deflection angle are similar to those from experimental hinge moment measurements made on wind tunnel models with swept supercritical wings tested at similar values of free stream Mach number and angle of attack.

Download Hinge Moments of Sealed-internal-balance Arrangements for Control Surfaces Book in PDF, Epub and Kindle
Summary: The results of a theoretical analysis of the hinge-moment characteristics of various sealed-internal-balance arrangement for control surfaces are presented. The analysis considered overhangs sealed to various types of wing structure by flexible seals spanning gaps of various widths or sealed to the wing structure by a flexible system of linked plates. Leakage was not considered; the seal was assumed to extend the full spanwise length of the control surface. The effect of the developed width of the flexible seal and of the geometry of the structure to which the seal was anchored was investigated, as well as the effect of the gap width that is sealed.

Download An Experimental Investigation of the Hinge-moment Characteristics of a Constant-chord Control Surface Oscillating at High Frequency Book in PDF, Epub and Kindle
The results of an experimental investigation of the hinge-moment characteristics of a constant-chord control surface oscillating at high frequency is presented. The control surface was mounted on an aspect-ratio-2 triangular wing. The aerodynamic restoring-moment coefficient and damping-moment coefficient were determined at a frequency of 260 cycles per second for a Mach number range of 0.6 to 0.8 and 1.3 to 1.9 at angles of attack of 5 degrees and 10 degrees.

Download Approximate Relations for Hinge-moment Parameters of Control Surfaces on Swept Wings at Low Mach Numbers Book in PDF, Epub and Kindle
This report contains derivations, based on an approximate theory, of equations for the hinge-moment parameters of control surfaces on swept wings at low Mach numbers. Method accounts for effects of sweep and aspect ratio, and considers, in an approximate manner, the effects of induced camber. Comparisons of calculated and experimental values of the hinge-moment parameters are presented.
