Download or read book A Flight Investigation of the Thermal Performance of an Air heated Propeller written by John F. Darsow and published by . This book was released on 1947 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal performance of an air-heated propeller, installed on a test airplane, was evaluated by observations of the ice-prevention propertiesof the propeller during flight in natural-icing conditions and by the collection of thermal data on the propeller during flight in clear air and in clouds at temperatures above freezing. The test propeller was equipped with hollow steel blades of a standard design which were altered to permit heated air to enter the blade cavities at the propeller hub and to leave the cavities at the blade tips. No provisions were made to control the distribution of air flow inside the blades.

This book was released on 1941 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal properties are presented for the exhaust heated wing de-icing system of a Lockheed 12-A airplane which has successfully prevented wing icing in 25 hours of flying in various icing conditions. The quantities of heat supplied for de-icing of the wings under various conditions were measured and are presented. The distribution of temperatures above the ambient air temperature for the wing surface under various operating conditions are given. The design and construction factors relative to the weight, maintenance, and the applicability to exhaust heating on other airplanes are discussed.

This book was released on 1948 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: The landing of a simplified airplane structure, consisting of a uniform beam for the wings, a concentrated mass for the fuselage, and a linear spring for the landing gear, is analyzed exactly and is compared with several approximate solutions. The approximate solutions which neglect elasticity in the determination of landing-gear reaction but consider elasticity in computations of stresses give results of good accuracy and indicate that drop tests in which rigid masses are used may be a satisfactory approach to the landing problem.

Book excerpt: An investigation was conducted to determine the thermal and hydrodynamic behavior of air in the downstream portion of two types of double-skin passages used in heating-air leading-edge anti-icing systems. The downstream average unit thermal conductance in the turbulent region was 30 to 35 percent below that given by the commonly used equations. In the laminar region, the experimental unit conductance was about 30 percent below the predicted values for rectangular ducts but for trapezoidal ducts the data were much lower than the predicted values.
