The use of electronic computers instead of graphic methods for turbine blade calculation requires preliminary determination of the geometric parameters. To determine the dependence of these parameters on other known turbine blade characteristics, measurements were made of a series of blade cascades of various types of aircraft turbine engines. Formulas were derived for maximum blade thickness, blade profile area, inlet edge radius, inlet and exit angles, and blade angle. The interrelationship of geometric parameters was found to be the same for both nozzle and rotor blade cascades.
