520 3 ⊔ ‡aAsymmetric air-flow characteristics of supersonic twin-intake air-induction systems were studied with inlets having peak static-pressure recovery at greater than 50-percent mass flow and critical static-pressure recovery equal to or greater than the value at zero mass flow. Analytical predictions of asymmetric flow and initial flow reversal agreed with the experimentally observed trends. Initial flow reversal (i.e., a zero flow in one duct) occurred simultaneously with critical inlet flow in the other duct. Thus, in terms of engine throttling, engine air flow cannot be reduced to less than half the total inlet critical air flow before initial flow reversal occurs.
