Practical Guide to
Performance and Design
by Donald R. Crawford
Includes nomograms & templates for quick performance predictions
The analyses described in this book can be used by the first time designer to calculate the complete performance of the airplane from seven parameters; gross weight, drag area, wing span, wing area, maximum lift coefficient, horsepower, and propeller diameter. All design variables are mathematically related to these parameters by equations derived through the design nomograms in this book.
A Practical Guide to Airplane Performance and Design is for the designer who wants to understand and compare how physical characteristics of an airplane contribute to its performance (speed, climb, stall, glide, etc...), and then implement those design choices to obtain that desired performance. With this book, calculated data can then be deciphered by the use of mathematics or with an enclosed plastic template and nomograms.
