Abstract
Disclosed herein are various dynamometer embodiments in which the devices have a cooling tank comprising cooling fluid, a rotatable drum body disposed over a stator body, and first and second friction disks axially extendable from the stator body such that the friction disks are frictionally engageable with the bases of the drum body. The bases of the drum body can be rotatable friction plates that are coupled via a connection tube to form the drum body.
