Download or read book Analysis of Propeller Efficiency Losses Associated with Heated air Thermal De icing written by Blake W. Corson and published by . This book was released on 1946 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis is made of the loss of efficiency associated with a heated-air thermal de-icing propeller both with and without internal flow. For the available data, measured efficiency losses are compared with the calculated losses and the agreement is found to be within the experimental accuracy of the data. The method presented may be used with reasonable accuracy to determine the net change in propeller efficiency due to the combined effects of the nozzle and internal flow if the characteristics of the propeller without nozzles are known.

Download or read book Tank Tests to Determine the Effect of Varying Design Parameters of Planing tail Hulls written by John R. Dawson and published by . This book was released on 1946 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second part of a series of tests made in Langley tank no. 2 to determine the effect of varying design parameters of planing-tail hulls is presented. Results are given to show the effects on resistance characteristics of varying angle of afterbody keel, depth of step, and length of afterbody chine. The effect of varying the gross load is shown for one configuration. The resistance characteristics of planing-tail hulls are compared withthose of a conventional flying-boat hull. The forces on the forebody and afterbody of one configuration are compared with the forces on a conventional hull.

This book was released on 1946 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic tests of a 12.208-foot-diameter two-blade hollow steel propeller before and after alteration for thermal de-icing have been made in the Langley 16-foot high-speed tunnel to determine the effect of the alterations on propeller efficiency. The propeller, which had Clark Y blade sections, was tested on a 2000-horsepower dynamometer at blade angles ranging from about 25 degrees to 60 degrees at the 42-inch radius and at airspeeds varying from 100 to 425 miles per hour.
