Critical Evaluation of a Nonuniform Flow Sonic Boom Reduction Concept.
Abstract
An investigation was made of a 'nonuniform flow field' sonic boom elimination device. The two-dimensional flow field consists of a slit jet impinging on an inclined fat plate airfoil. The report presents independent analyses of the problem as well as a critique of the analysis. The major finding is that one can expect no more than a 10% reduction in the strength of the leading edge shock wave at a thousand chord lengths from the plate when compared to the corresponding case without jet flow (same chord and lower surface pressure). Under identical conditions, a 20% reduction is found. (Author)
