Download or read book Experimental Spindle Torque and Open water Performance of Two Skewed Controllable pitch Propellers written by Robert J. Boswell and published by . This book was released on 1975 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are presented on the spindle torque and open-water performance of two skewed controllable-pitch propellers. Both propellers have radial distributions of skew specified so that the section midchord is forward of the spindle axis at the inner radii and aft of the spindle axis at the outer radii. One propeller has no rake and the other has substantial forward rake. The experiments were conducted at steady conditions in uniform flow in a towing basin over a range of positive and negative pitch ratios and a range of positive and negative advance coefficients so that the complete maneuvering envelope of the ship was simulated in a quasi-steady manner. The experimental open-water performance was correlated with calculated values based on a least-squares fit to previous systematic experimental data.

This book was released on 1967 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study is presented of the blade spindle torque of five controllable-pitch propeller models, representing five different designs for MSO-421. The study covers a range of both positive and negative advance coefficients at both ahead and astern pitch settings. It was found that the blade with spindle axis located 40 percent of blade width from the leading edge and with uncambered National Advisory Council for Aeronautics Series 66 (NACA 66) airfoil blade sections modified by the Bureau of Ships required the least extreme value of spindle torque.

Available in PDF, EPUB and Kindle. Book excerpt: This report is a summary of the controllable pitch (CP) propeller blade attachment investigations which were conducted by the David W. Taylor Naval Ship Research and Development Center subsequent to the failure of the CP propeller on the USS BARBEY (FF-1088). Analysis of the BARBEY failures revealed that there was insufficient information available concerning design loads, structural response, and material selection for CP propeller hub components.

Book excerpt: A series of open water propeller tests was conducted with an adjustable pitch propeller with 2, 3, 4, 5 and 6 blades. The faired coefficient curves of thrust, torque, and efficiency are presented with the propeller design. An example is given to illustrate the use of the curves in selecting the optimum propeller for a given set of conditions. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Blade spindle-moment values are presented for the operation of a five-bladed controllable-pitch propeller over a range of blade pitches and advance conditions. Spindle moment (blade turning effort) was measured on a single blade of NSRDC Model Propeller 4402 in an experimental program conducted in the 24-in. variable-pressure water tunnel. Experimental results are presented as mean spindle-moment values taken at steady-state operating conditions. No transient or time-dependent data were taken. The operating conditions investigated (1) positive pitch--steady ahead, (2) negative pitch--steady backing, and (3) negative pitch--ahead advance. The spindle moment due to hydrodynamic loading and that due to centrifugal forces were separated and nondimensionalized. The effects of Reynolds number and propeller blade cavitation are discussed briefly. (Author).
