Statistical analysis in the aerodynamic forces and moments measurement in indonesian low-speed wind tunnel

Abstract

The reliability of measurement should be based on accuracy and precision. A reliable measurement system will deliver quality results of data. Quality of the data will affect the decision which taken based on analysis of the data. A decision taken based on poor quality data will lead to a misleading action. This paper presents application statistical analysis in the aerodynamics measurement system in Indonesian Low-Speed wind Tunnel (ILST), using case of repeatability data on testing of Unmanned Aircraft Vehicle (UAV) model, in terms of one-way and two-way analysis of variance. The aerodynamics measurement system could be considered to accept statistically. The calculation was performed ratio of F to P using One-ways Analysis of Variance (ANOVA) methods indicate almost equal to zero. In case data is small we used Two-way ANOVA analysis show the variance also very small. That calculation results showed the measurement system can be categorized as an acceptable and proper measurement.
