Some measurements were made of the aerodynamic forces and moments acting on a rectangular wing of aspect ratio 2 which was oscillated about the midchord. These measurements were made at four frequencies (31, 43, 54, and 62 cps) over a range of Mach number from 0.15 to 0.81, a range of reduced frequency from 0.15 to 1.32, and a range of Reynolds number from 0.60 x 10 to the sixth power to 9.21 x 10 to the 6th power. It was feasible to compare results of a portion of these measurements with some published experimental data and, in general, reasonable agreement was found to exist. An appendix is included to show the correction of the root reaction for inertia and aerodynamic effects in order to determine the total aerodynamic load. Comparison of the measured aerodynamic forces and moments with those predicted by the method of Reissner and by the method of Lawrence and Gerber for wings of aspect ratio 2 in incompressible flow showed generally good agreement. Comparison of the measured quantities with those predicted by two-dimensional-flow theory indicated that the effects of finiteness of span on the aerodynamic forces and moments are considerable. Some experimental results pertaining to the influence of wind-tunnel-wall effects on nonsteady aerodynamic measurement have been included.

A study was made to determine the probable causes of deterioration of each of several adhesives in bonds to stainless steel at temperatures from 400 to 550 degrees F. Prellminary studies of aluminum surfaces on which ions of metals used in staLnless steel were introduced showed that iron was probably catalyzing a thermal deterioration of the adhesive. The resistance of FPL-878 adhesive to thermal deterioration at 550 degrees F on steel was improved signiffcantly by treating the steel surface to be bonded with either zinc or cerium naphthenate and firing at 1,200 degrees F. The addition of manganese dioxide to the adhesive also increased its resistance to thermal deterioration. A study of the thermal-aging properties of five different chemical types of adhesives on stainless steel and alumina revealed that a phenol-nitrile rubber adhesive was superior to a phenol-epoxy adhesive on steel, but this order was reversed on alumina. These and other observations indicated probable specific relationships among the chemical structure of the adhesive, the metal adherend, and the resultant thermal stability of bonds after aging at high temperatures.
