| Abstract: | Temperature distortion on inlet flow of engine is more important than pressure distortion for engine stability. This paper, studies some technical problems in the measurement of temperature distortion of engine and the adjustment of simulation equipment by using a high speed and huge capacity data acquisition, real time storage and processing system. Experimental data and analytic results are successfully obtained. The affecting factors of measurement precision are also discussed. Finally some advice and important information are presented. |
