Elements of Propeller and Helicopter Aerodynamics

By Daniel O Dommasch

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.
