Book excerpt: Tests were made of a number of 10-inch shear panels of 24S-T aluminum alloy with 1- 1/2-inch holes to determine the stress concentrations at static rupture and the deformation characteristics. The average factor of stress concentration was found to be about 1.1; reinforcements around the edges of the holes did not increase the ultimate strengths. Permanent set began in specimens without holes at nominal shear stresses of 10 to 12 kips per square inch. In thin specimens with holes, permanent set began at the buckling stress.

Download or read book The Knock Limited Performance of Fuel Blends Containing Aromatics 1 Toluene Ethylbenzene and P Xylene written by and published by . This book was released on 1944 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to determine blending sensitivity, lead susceptibility, and sensitivity of the blends to inlet-air temperature, knock-limited small-scale-engine tests were made of toluene, ethylbenzene, p-xylene blended individually in various concentrations with selected base fuels. Toluene, ethylbenzene, and p-xylene increased the knock-limited indicated mean effective pressures of the two base fuels from 5-183 percent at high fuel air ratios depending on operating conditions and percentage of aromatics. At lean fuel air mixtures the addition of the aromatics increased the knock-limited indicated mean effective pressure of the base fuel 10-39 percent in the full-scale cylinder and 0.33 percent in the 17.6 engine. The general trend indicated that the lead susceptibility of the aromatic blends increased with increasing aromatic content and decreased with increasing inlet-air temperature.

Available in PDF, EPUB and Kindle. Book excerpt: In the 1930s, as nations braced for war, the German military build up caught Britain and the United States off-guard, particularly in aviation technology. The unending quest for speed resulted in the need for radical alternatives to piston engines. In Germany, Dr. Hans von Ohain was the first to complete a flight-worthy turbojet engine for aircraft. It was installed in a Heinkel-designed aircraft, and the Germans began the jet age on August 27, 1939. The Germans led the jet race throughout the war and were the first to produce jet aircraft for combat operations. In England, the doggedly determined Frank Whittle also developed a turbojet engine, but without the support enjoyed by his German counterpart. The British came second in the jet race when Whittle's engine powered the Gloster Pioneer on May 15, 1941. The Whittle-Gloster relationship continued and produced the only Allied combat jet aircraft during the war, the Meteor, which was relegated to Home Defense in Britain. In America, General Electric copied the Whittle designs, and Bell Aircraft contracted to build the first American jet plane. On October 1, 1942, a lackluster performance from the Bell Airacomet, ushered in the American jet age. The Yanks forged ahead, and had numerous engine and airframe programs in development by the end of the war. But, the Germans did it right and did it first, while the Allies lagged throughout the war, only rising to technological prominence on the ashes of the German defeat. Pavelec's analysis of the jet race uncovers all the excitement in the high-stakes race to develop effective jet engines for warfare and transport.
