Estimation of low-speed lift and hinge-moment parameters for full-span trailing-edge flaps on lifting surfaces with and without sweepback / Jules B. Dods, Jr.
A method is proposed for estimating the lift and hinge-moment parameters of lifting surfaces with and without sweep. The method is based upon lift predictions presented in NACA Report 921, 1948 and upon estimates of the induced-camber aspect-ratio corrections to the hinge-moment parameters computed...

| Summary: | A method is proposed for estimating the lift and hinge-moment parameters of lifting surfaces with and without sweep. The method is based upon lift predictions presented in NACA Report 921, 1948 and upon estimates of the induced-camber aspect-ratio corrections to the hinge-moment parameters computed from a solution of the chordwise loading by the Falkner method. Design charts for the induced-camber correction are provided so that the method may be applied without extensive computations of the surface loading. The theoretical results are compared with expermental results for four horizontal-tail models without sweepback and for five horizontal-tail models with sweepback. |
