The article considers a possibility of creating a drive based on the effect of "Ultimate pneumatic hammer" in the radial gas-static bearing. It summarizes the conditions of occurrence of the effect of "limiting pneumatic hammer". We draw up recommendations on the application of the drive in the air conditioning systems of modern aviation aircraft, refrigeration. The prospects of the use of the drive as the rotating mechanism of intrinsically safe shut-off valve are shown. The first results of theoretical studies of gas-static bearings operating in the "limit pneumatic hammer" mode were obtained in a three-dimensional mapping. For the first time we present a stand for investigation of driving performance, as well as the first results on the basis of which we defined features of occurrence of the "limiting pneumatic hammer" mode. Also we found equations and the structure of the phase diagram, corresponding the regimes "pneumatic hammer" and "limiting pneumatic hammer". Basic conditions for the appearance of the "limiting pneumatic hammer" mode were established. Also for the first time we clarified dependence, which leads to the effect of "limiting pneumatic hammer". The basic design and operational requirements of the developed drive were determined. Analysis of the obtained results allowed to put forward further steps of development and the shape of a new drive.
