Download or read book Method of Calculating Performance of Dual-rotating Propellers from Airfoil Characteristics written by Irven Naiman and published by . This book was released on 1943 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method developed for calculating the performance of a dual-rotating propeller from the section characteristics of the blade elements. The method is applied to an eight-blade dual-rotating propeller and the computed results are compared with low-speed wind-tunnel tests of the same propeller in both the tractor and the pusher positions. The computations are found to agree within the experimental accuracy of the measurements. A detailed step-by-step procedure for the computations is given in an appendix.

Download or read book Application of Theodorsen's Propeller Theory to the Calculation of the Performance of Dual-rotating Propellers written by Jean Gilman and published by . This book was released on 1951 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theodorsen's propeller theory is used to calculate the performance of a dual-rotating propeller having nonideal load distributions. The application of this theory to either performance or design calculations of dual-rotating propellers is found to involve a modification to the value of the mass coefficient, which is shown to be affected by the ratio of the spinner radius to the propeller radius. The effect is very important and, since it has not been considered in previous work on this subject, the required modification and the method of application is explained in the present paper.

Download or read book Charts for Determining Propeller Efficiency written by John L. Crigler and published by . This book was released on 1944 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: A short method of estimating propeller efficiency for a given operating condition is described. The efficiency is determined for any design condition by evaluating separately from charts the induced losses and the profile-drag losses. The estimated efficiency is compared with experimental results for a wide range of operating conditions and found to be in agreement near peak efficiency. The present analysis covers single-rotating propellers of two, three, four, six, and eight blades and includes charts showing the rotational-energy loss for the given operating condition in order to assist in estimating the gain in efficiency for dual-rotating propellers. The change in efficiency to be expected from body interference is discussed. Two examples illustrating the use of the method are given in an appendix.
