Gas Dynamic Designing of Pneumatic Braking System for Gas Turbine Engine Test Bench

The purpose of this research was the gas-dynamic design of the pneumatic brake system on the basis of the existing geometry of the three stage axial flow low-pressure compressor for application in the GTE test benches.

The pneumatic brake system has been obtained by adding of the add stage to the low-pressure compressor, the geometry of which repeats the geometry of the stages of the base compressor. In this work, two options were considered. First, the second stage of the base compressor was used as the add stage. Second, the third stage of the base compressor was used as the add stage.
