The Heat of Solution of Uranium Tetrachloride in Aqueous Perchloric Acid Solutions

Abstract: "The heat of solution of UCl4 solid has been measured and found to change appreciably with changing concentration of H+ or ionic strength. The heat of hydrolysis of U+4 to form UOH+3 is probably of the order of +11 kcal per mole" (p. 1).

Investigation in the Langley 19-foot pressure tunnel of two wings of NACA 65-210 and 64-210 airfoil sections with various type flaps (open access)

Investigation in the Langley 19-foot pressure tunnel of two wings of NACA 65-210 and 64-210 airfoil sections with various type flaps

Report presents the results of an investigation conducted in the Langley 19-foot pressure tunnel to determine the maximum lift and stalling characteristics of two thin wings equipped with several types of flaps. Split, single slotted, and double slotted flaps were tested on one wing which had NACA 65-210 airfoil sections and split and double slotted flaps were tested on the other, which had NACA 64-210 airfoil sections. Both wings were zero sweep, an aspect ratio of 9, and a taper ratio of 0.4.
