Design and Analysis of the Multi-Microchannel Aerostatic Restrictor

Abstract:

Restrictors are one of core parts in aerostatic systems. A special multi-microchannel aerostatic restrictor is designed and developed, and the air film thickness is measured by the capacitive measuring method. The mathematical model of capacitance and air film thickness is carried out, capacitances of specific air film thickness are calculated, air film thickness of the multi-microchannel aerostatic restrictor with the overall diameter is measured, and error sources processed and analyzed. Results illustrate that errors between the theoretical calculations and the experimental data are less than 13%, this proves the correctness of the mathematical model as well as the effectiveness of the capacitive measuring method applying for the air film thickness measurement of the aerostatic systems.
