一个微型，高速压缩机叶轮（直径12毫米，800，000转）进行了测试的可行性方面的气动性能。该压气机设计用于拳头大小的燃气轮机发电机。为了在如此高的温度下承受高应力，转子通过模具SDM工艺制造为氮化硅中的单个涡轮机/压缩机/轴单元。在冷流试验台中以420，000 rpm的降低速度进行性能测试。计算流体动力学代码的结果与此速度下的测量数据相比是有利的。通过在两种速度下应用计算流体动力学，完成了从试验条件到全设计速度的外推。
A micro-scale, high-speed compressor impeller (12mm diameter, 800,000rpm) was tested for feasibility in regard to aerodynamic performance. The compressor was designed for application in a fist-sized gas-turbine-generator. To survive high stresses at such high temperatures, the rotor was manufactured as a single turbine/compressor/shaft unit in silicon nitride, by the Mold SDM process. Performance testing was conducted in a cold-flow rig at reduced speed of 420,000rpm. Results from a CFD code compared favorably to measured data at this speed. Extrapolation from test conditions to full design speed was accomplished by application of CFD applied at both speeds.
