压气机模型减缩RCS试验研究

减缩压气机RCS的后向散射,是降低进气道RCS主要技术途径之一,本文通过缩比压气机模型涂敷RAM不同方案的试验研究,获得的最佳涂敷RAM方案,在小方位角时能达到降低9.3～9.7dB的最佳效果。同时指出,这一成果的应用,还有许多技术工作要做。

INVESTIGATION OF COMPRESSOR MODEL TEST FOR RCS REDUCTION

Reducing backcattering of RCS of compressors is the one of major technical ways to decrese RCS of inlets. This Paper gives a test investigation of applying several different RAM coating on a scale compressor model to determine the optimum RAM coating scheme by using which the optimum effect to reduce 9.3 - 9. 7dB in the RCS average can be achieved when the azimuth angle is lower. Meanwhile, it should be pointed out that there are lot of technical work to be done for the application of this result.
