A list of standard symbols for rotating-wing aircraft is presented. The list of symbols is subdivided for ready reference under appropriate headings, the symbols being restricted to those most generally used in studies of helicopter aerodynamics. Great interest has been shown by manufacturers of helicopters and by various government agencies charged with the design, evaluation, and procurement of helicopters in the standardization of symbols for use in their work. A survey was therefore conducted among members of the armed services, industry, certain educational institutions, and various government agencies in order to obtain an indication of their preferences. This survey was made by the Helicopter Committee of the Society of Automotive Engineers in cooperation with the NACA Subcommittee on Helicopters. The results of the survey indicated a definite preference for those symbols that had been most widely used in the past. Accordingly, a list of symbols that have appeared in many papers on rotating-wing aircraft has been prepared and correlated. This list, which is presented herein, was approved as standard by the members of the NACA subcommittee on Helicopters at a meeting held on December 3, l947. The membership of this Subcommittee is considered representative of the various groups contacted during the aforementioned survey. The symbols listed have been limited for the present to those most generally used in helicopter aerodynamic studies. Specialized symbols necessary in vibration, stress, and stability work remain to be developed and standardized as these studies mature with time and use.
