Abstract: 
The questions of hydrostatic bearing activity are considered. An influence of flow conditions of lubricating material on power losses in reference units of power installations of flight vehicles is investigated. The conclusions about value of power losses on abrasion and scavenging are made. The graphic relations of energy losses from angular rate of rotation and from value of relative eccentricity are constructed. These investigations are important and actual for projection of fast-running machines curls, because on high speeds the resource of other kinds of bearings is extremely limited.
