Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

This book was released on 2018-09-10 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2016 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following research determines the feasibility of predicting control surface hinge mo- ments using various computational methods. A detailed analysis is conducted using a 2D GA(W)-1 airfoil with a 20% plain flap. Simple hinge moment prediction methods are tested, including empirical Datcom relations and XFOIL. Steady-state and time-accurate turbulent, viscous, Navier-Stokes solutions are computed using Fun3D. Hinge moment coefficients are computed. Mesh construction techniques are discussed. An adjoint-based mesh adaptation case is also evaluated. An NACA 0012 45-degree swept horizontal stabilizer with a 25% ele- vator is also evaluated using Fun3D. Results are compared with experimental wind-tunnel data obtained from references. Finally, the costs of various solution methods are estimated. Results indicate that while a steady-state Navier-Stokes solution can accurately predict control surface hinge moments for small angles of attack and deflection angles, a time- accurate solution is necessary to accurately predict hinge moments in the presence of flow separation. The ability to capture the unsteady vortex shedding behavior present in mod- erate to large control surface deflections is found to be critical to hinge moment prediction accuracy. Adjoint-based mesh adaptation is shown to give hinge moment predictions similar to a globally-refined mesh for a steady-state 2D simulation.
