EXPERIMENTAL ANALYSIS OF A PLASTIC MODEL MULTICELL CANTILEVER BOX BEAM WITH 30 DEGREE SWEEP.

Abstract

An experimental analysis of a plastic model four-cell swept back wing is presented. The model is cantilevered with a massive root rib oriented 60 degrees with the spars. Three other ribs are located perpendicular to the spars. The results were compared with results previously obtained from tests performed on an aluminum alloy model of the same structure. Spanwise stresses and deflections compared very well. Considerable error was observed in chordwise stresses and shear stresses due to lack of joint duplication at the root rib and a difference in Poisson's Ratio between the two materials. (Author)
