Effect of Fabric Deflection at High Speeds on the Aerodynamic Characteristics of the Horizontal Tail Surface of an SB2D-1 Airplane

Abstract

Two fabric-covered elevators with rib spacing of 4 in. and 8 in., respectively, and a solid wood elevator were tested at maximum Mach number of 0.68. No appreciable fabric deflections occurred for elevator with 4 in. rib spacing. Marked increases in elevator hinge-moment coefficients occurred as Mach number increased. Effect of fabric deflection for elevator with 8 in. rib spacing caused an additional adverse increment in hinge-moment coefficient as speed increased. Effectiveness of elevator with 4 in. rib spacing did not change with Mach number, while effectiveness with 8 in. rib spacing decreased sharply at Mach number above 0.56.
