Book Synopsis The Effect of Trailing-edge Extension Flaps on Propeller Characteristics by : John L. Crigler
Download or read book The Effect of Trailing-edge Extension Flaps on Propeller Characteristics written by John L. Crigler and published by . This book was released on 1945 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: An analysis was made to determine the effect on propeller performance of extension flaps added to the trailing edge of a propeller blade. A method of calculating the changes in the ideal angle of attack, the angle of zero lift, and the design lift coefficient of a propeller blade section having a trailing-edge extension flap was utilized to calculate the performance of a six-blade dual-rotating propeller with extension flaps varying up to 40 percent chord. The method was used to determine the angle that the flap extension must make with the chord in order to obtain a particular load distribution. Although the analysis in this report was made for a wind-tunnel propeller designed to operate at low advance-diameter ration, the method is directly applicable to any propeller section under any operating condition.

Download or read book Effect of a Trailing-edge Extension on the Characteristics of a Propeller Section written by Theodore Theodorsen and published by . This book was released on 1944 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented to evaluate changes in airfoil characteristics resulting from extension of chord at trailing edge of propeller blade section. Method determines changes in angle of zero lift, angle of attack, and difference in these angles (upon which design lift coefficient depends) as function of angle and length of trailing edge extension. Treatment is based on thin-airfoil theory and is concerned only with mean camber line of section. Examples and detailed computations illustrate application of method, which is applicable to all propeller sections. Characteristics obtained were in perfect agreement with data calculated by exact method of arbitrary airfoil theory.

Book excerpt: Propellers with trailing-edge extensions were studied to determine aerodynamic characteristics. Trailing-edge extension increased power absorbed by propeller with little loss in efficiency. Power coefficient for maximum efficiency was greater for 20 percent camber type extension than for 20 percent straight type extension over range of advance ratio of 1.0 to 2.5 although camber type was less efficient. Efficiency was about the same for cruising and high-speed at a high power coefficient for propeller with extension.

Book Synopsis Marine Propellers and Propulsion by : John Carlton
Download or read book Marine Propellers and Propulsion written by John Carlton and published by Butterworth-Heinemann. This book was released on 2012-11-23 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Propulsion technology is a complex, multidisciplinary topic with design, construction, operational and research implications. Bringing together a wealth of disparate information from the field, Marine Propellers and Propulsion provides comprehensive and cutting edge coverage to equip marine engineers, naval architects and anyone involved in propulsion and hydrodynamics with the knowledge needed to do the job. Drawing on experience from a long and varied career in consultancy, research, design and technical investigation, author John Carlton breaks the subject into three main sections - hydrodynamic theory, materials and mechanical considerations, and design, operation and performance. Connecting essential theory to practical problems in design, analysis and operational efficiency, Marine Propellers and Propulsion is an invaluable resource, packed with hard-won insights, detailed specifications and data. The most complete book available on marine propellers, fully updated and revised, with new chapters on propulsion in ice and high speed propellers Gathers together otherwise disparate material on the theory and practice of propulsion technology from the past 40 years’ development, including the latest developments in improving efficiency Written by a leading expert on propeller technology, essential for students, marine engineers and naval architects involved in propulsion and hydrodynamics
