Abstract: 
Laminar-turbulent transition regime in a slot between flat disks rotating around the axis at the same velocity is investigated. The slot is a working element of disk pumps, compressors, turbines, and fans recommended for space power units. Instabilities of varions types which appear in the flow as well as the velocity distribution in the slot were determined by optical methods. Experimental relations lips hips which define the beginning of laminar-turbulent transition and its end were obtained.
Keywords: disk hydraulic machines, space power unit
