Download or read book The NACA Balanced diaphragm Dynamometer torque Indicator written by Charles S. Moore and published by . This book was released on 1944 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A balanced-diaphragm device for measuring dynamometer torque of single-cylinder or multi-cylinder engines is described. This device, which was developed for laboratory use, has proved to be accurate, reliable, and adaptable. Compressed air, automatically controlled, is used as the balancing and the transmitting fluid; thus, a simple method of obtaining torque measurement at a remote position is provided.

This book was released on 1948 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results indicate that cross-sectional shape and aspect ratio are minor factors compared with radius ratio in affecting the velocity pattern. Variation of Reynolds number within the range of the tests had no appreciable effect on the velocity distribution in curved ducts.

Download or read book The Effect of Simulated Icing on Propeller Performance written by Blake W. Corson and published by . This book was released on 1946 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of a 10-foot-diameter three-blade Curtiss 89301-15 propeller with Clark Y blade sections have been conducted in the Langley 16-foot high-speed tunnel in order to determine the effect of simulated iceon the aerodynamic characteristics of the propeller. The irregular coat of cement and fabric was used on the blades to simulate in outline and thickness a formation of glaze ice that might be formed in flight. The propellers were tested on a new 2000-horsepower dynamometer, a brief description of which is included. All tests were made at a rotational speed of 1800 rpm for blade angles of 20, 25, 35, and 40 degrees at the 42-inch radius and at airspeeds varying from 120 to 420 miles per hour. The results are representative of full-scale constant-speed propeller operation.

This book was released on 1947 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dynamometer-stand investigation was conducted to determine the effect of exhaust pressure on the performance of a 12-cylinder liquid-cooled aircraft engine equipped with a conventional exhaust collector. The investigation covered a range of exhaust pressures from about 7 to approximately 62 inches of mercury absolute, engine speeds from 1600 to 3000 rpm, inlet-manifold pressures from 30 to 50 inches of mercury absolute and fuel-air ratios of 0.063, 0.069, 0.085, and 0.100.
