Abstract

To determine the operational boundaries of pneumatic brakes based on multistage axial compressors, recommendations have been developed for selecting the configuration and parameter values of the finite element flow mesh in these devices. The proposed recommendations allow for a reduction in the number of mesh elements in models of the compressor's inter-blade channels without decreasing the accuracy of determining the operational boundaries of pneumatic brakes. Testing of the developed recommendations has shown that their application enables more than a twofold reduction in the time required for the gas-dynamic design of pneumatic brakes.
