The purpose of this paper is to present a method of simplifying those so far used in determining the cascade characteristics. Specially-designed probes, which swing through an amplitude of one blade spacing at a constant speed in the downstream of blade cascade, were used in order to obtain average values of spatial pressure distribution. A model measuring apparatus was built, and its applicability was examined experimentally. The results are : 1. This swing method is applicable, if the coefficient of the total pressure loss is smaller than 0.1. 2. The error in average outlet static pressures and outlet angles by the swing method is confined within the limit of measuring errors. 3. If the coefficient of the total pressure loss is known, the coefficient of the wake momentum loss, which is necessary for obtaining the lift and drag coefficients, can be calculated on a few suppositions. 4. The adoption of the swing method will save the time by 1/8〜1/10 of that needed by any conventional method.
