Abstract

In the embodiment depicted, the dynamometer is of an absorption type, for fluid, having fluid entries on both axial ends thereof, and a rotor having blades disposed, in a radial exit flow path, in parallel with the rotor axis. Adjustable, annular, blade shrouds, controlled simultaneously, expose more or less of the blade lengths to the radial exit fluid flow path.
