Summary:

Fan brakes are widely used as absorption dynamometers in testing internal combustin engines because they are comparatively simple, in expensive and flexible. They do have the disadvantage that a given fan will will run at only one speed when the engine is delivering full power, that speed being determined by the size, proportions, and environment of the fan, and the density of the air. To be able to vary the speed at which a given power will be absorbed, English manufacturers have for some time been using a cylindrical housing around the fan with one or two variable openings in the periphery. The tests reported here were undertake by the Automotive Power Plant Section of the Bureau of Standards to determine how great a range of speed cna be obtained with such a device.
