Tracked Air Cushion Research Vehicle (TACRV). Air Cushion Experimental/Theoretical Correlation.

摘要

A modified version of the exponential theory of peripheral jet operation was selected by the manufacturer of TACRV for the prediction of the steady state performance of the TACRV air cushions. Air cushion performance observed during subsystem development tests indicate further modification is required to match the theory to test results. Subsequently, a slightly more concordant set of equations according to Burgess-Barratt were modified to account for the geometric effects of the TACRV nozzle. The resulting theory and test data appear to be in good agreement. The revised predictions of the pressure/flow/height performance of the TACRV levitation and guidance cushions present a more accurate estimation of their behavior. Further verification of the revised theory,based on data from the TACRV test program,will provide information for improved design of future TACVs. It should be noted that since the publishing of this report,the Tracked Air Cushion Research Vehicle (TACRV) has been renamed the Tracked Levitated Research Vehicle (TLRV).
