Summary: A technical method is given for calculating the axial interference velocity of a propeller. The method involves the use of certain weight functions P, Q, and F. Numerical values for the weight functions are given for two-blade, three-blade, and six-blade propellers.

Summary: Values of the circulation function have been obtained for dual-rotating propellers. Numerical values are given for four-, eight-, and twelve-blade dual-rotating propellers and for advance ratios from 2 to about 6. In addition, the circulation function has been determined for single-rotating propellers for the higher values of the advance ratio. The mass coefficient, another quantity of significance in propeller theory, has been introduced. This mass coefficient, which is actually the mean value of the circulation coefficient, expresses the effective area of the column of the medium acted upon by the propeller in terms of the propeller-disk area. Values of the mass coefficient, which have been determined directly by special measurements and also by integration of the circulation function, are given for the four-, eight-, and twelve-blade dual-rotating propellers. The mass coefficient has also been determined for several cases of single-rotating propellers, partly for the purpose of comparing such experimental values with theoretical results in the known range of low advance ratios and partly to extend the results to include a range of high advance ratios. The effect of stationary countervanes on the mass coefficient has also been determined for several cases of practical interest.

The author: Makes minimum use of nondimensional coefficients, and takes great care to define them, and to show their function, their use in the industry and their physical meaning. Contrast this with a typical exposition of the "momentum method," in which the reader is lost in C sub this and C sub that after the first page. Uses the technique of dimensional analysis in explaining the operation of propellers. Explains all the theoretical treatments relevant to the task at hand, shows their relation to one another and gives examples contrasting the procedure and the solutions obtainable with each theory. Each chapter has relevant references listed at the end.In the helicopter section, makes use of propeller theory and gives a clear exposition of the special problems of helicopters. Here again, instead of spending pages expounding the details of theory, he states the results, explains their limitations, and again offers examples. And if that were not enough, he covers numerical procedures for solving problems, which means that this sixty-year-old book is a good basis for digital computer programs or MathCAD worksheets solving the relevant problems. In fact, the computation forms published in the book can easily be converted to spreadsheets.It is true that the book is not a comprehensive or encyclopedic treatment of helicopters. The problem of vibration is not covered, for example. Thus, this text will be useful in preliminary design, but a more detailed text will be needed for more advanced work.

As a first step in the formulation of a rational propeller theory for compressible flow, the axial momentum theory for compressible flow has been developed. The flow conditions predicted are significantly different from those predicted for incompressible flow. Charts are presented for flow conditions for an ideal propeller at a Mach number of 0.7 and are used as the basis for a discussion of the implications of theory.
