SummaryExperiments are described in which the lift on a rectangular element of a two-dimensional wing and on a finite aspect ratio wing has been measured in grid turbulence. By measuring the spectrum of the lift and the spectrum of the turbulence upwash component, an experimental value for the turbulent admittance may be found. This is compared with a calculated value based upon linearised theory.

This paper describes an experimental evaluation of the effects of the intensity and scale of turbulence on the drag coefficient of two-dimensional rectangular cylinders exposed to grid turbulence. It is observed that the mean drag coefficient is principally influenced, for a given cylinder, by the intensity of turbulence and that the scale of turbulence plays a secondary role.
